307 - FLOWCHART
PERMANENT RULES
LABOR AND INDUSTRIES
Purpose: The Department of Labor and Industries (L&I) is continuing a long-term effort to provide one book for all the safety and health requirements for agriculture. This one-book requirement results from a 1995 legislative requirement that directed the department to publish all agriculture safety rules in one volume and a 2001 agreement between L&I and agricultural industry stakeholders to add applicable occupational health requirements to one book. The occupational health requirements in chapter 296-62 WAC are the focus of the current effort. Several rules from chapter 296-62 WAC were recently rewritten for clarity as part of the agency's plain language initiative. This rule making adopts these rewritten rules into the agriculture safety standard chapter 296-307 WAC.

Employer Chemical Hazard Communication
AMENDATORY SECTION(Amending WSR 01-17-033, filed 8/8/01,
effective 9/1/01)
WAC 296-307-550
Employer chemical hazard
communication -- Introduction.
Important:
Thousands of chemicals can be found in today's workplaces. These chemicals may have the capacity to cause health problems, from minor skin irritations to serious injuries or diseases like cancer.
The employer chemical hazard communication rule was developed to make sure employers and employees are informed about chemical hazards in the workplace.
This rule applies to:
• Employers engaged in businesses where chemicals are used, distributed, or produced for use or distribution.
• Contractors or subcontractors that work for employers engaged in businesses where chemicals are used, distributed, or produced for use or distribution.
| Note: |
| • | If you produce, import, distribute and/or repackage chemicals, or choose not to rely on labels or material
safety data sheets provided by the manufacturer or importer, you must comply with (( |
| • | You may withhold trade secret information under certain circumstances, see Trade secrets, WAC 296-62-053, to find out what information may be withheld as a trade secret and what information must be released. |
| EXEMPTIONS: |
| • | For the purposes of this employer hazard communication rule, if you are engaged in agricultural production of crops or livestock, "employee" does not mean: |
| - Immediate family members of the officers of any corporation, partnership, sole proprietorship or other business entity or officers of any closely held corporation. |
| • | Certain products, chemicals, or items are exempt from this rule. Below is a summarized list of these exemptions. See WAC 296-307-55055 at the end of this rule to get complete information about these exemptions: |
| - Any hazardous waste or substance | |
| - Tobacco or tobacco products | |
| - Wood or wood products that are not chemically treated and will not be processed, for example, by sawing and sanding | |
| - Food or alcoholic beverages | |
| - Some drugs, such as retail or prescription medications | |
| - Retail cosmetics | |
| - Ionizing and nonionizing radiation | |
| - Biological hazards | |
| - Any consumer product or hazardous substance when workplace exposure is the same as that of a consumer | |
| ♦ Retail products used in offices in the same manner and frequency used by consumers can be termed "consumer products." Consumer products include things such as: Correction fluid, glass cleaner, and dishwashing liquid. |
| Example: | If you use a household cleaner in your workplace in the same way that a consumer would use it when cleaning their house, the exposure should be the same as the consumer's. ("In the same way" means using the household cleaner in the same manner and frequency.) A janitor using a household cleaner, such as bleach, throughout the day, is not considered to be consumer use. |
| – Manufactured items that remain intact are exempt for this rule. | |
| The following are examples: |
| Item | Covered by this rule | Not covered by this rule |
| Brick | sawed or cut in half | used whole or intact |
| Pipe | cut by a torch | bent with a tube bender |
| Nylon rope | burning the ends | tying a knot |
| – Manufactured items that are fluids or in the form of particles are not exempt for this rule. |
To inform and train your employees about the hazards of chemicals they may be exposed to during normal working conditions, or in foreseeable emergencies by:
• Making a list of the hazardous chemicals present in your workplace
• Preparing a written Chemical Hazard Communication Program for your workplace
• Informing your employees about this rule and your program
• Providing training to your employees about working in the presence of hazardous chemicals
• Getting and keeping the material safety data sheets (MSDSs) for the hazardous chemicals
• Making sure that labels on containers of hazardous chemicals are in place and easy to read
You must:
Develop, implement, maintain, and make available a written Chemical Hazard Communication Program
Identify and list all the hazardous chemicals present in your workplace
Obtain and maintain material safety data sheets (MSDSs) for each hazardous chemical used
Make sure that material safety data sheets (MSDSs) are readily accessible to your employees
Label containers holding hazardous chemicals
Inform and train your employees about hazardous chemicals in your workplace
Follow these rules for laboratories using hazardous chemicals
Follow these rules for handling chemicals in factory sealed containers
The department must:
Translate certain chemical hazard communication documents upon request
Attempt to obtain a material safety data sheet (MSDS) upon request
Exemption: Items or chemicals exempt from the rule, and exemptions from labeling

You must:
• Obtain a MSDS for each hazardous chemical used as soon as possible if the MSDS is not provided with the shipment of a hazardous chemical from the chemical manufacturer or importer.
| Note: |
| • | To obtain a MSDS, you may try calling the manufacturer or checking their website. |
| • | If you have a commercial account with a retailer or wholesaler, you have the right to request and receive a MSDS about hazardous chemicals you purchase. |
| • | If a chemical is purchased from a retailer with no commercial accounts, you have the right to request and receive the manufacturer's name and address so that you can contact them and request a MSDS for the chemical. |
| • | Whoever prepares the MSDS is required to mark all blocks on the form, even if there is no relevant information for that section. |
| • | If you have problems getting a MSDS within 30 calendar days after making a written request to the chemical manufacturer, importer, or distributor, you can get help from WISHA. You may contact your local regional office for assistance or make a written request for assistance to the: |
| Department of Labor and Industries | |
| Right-to-Know Program P.O. Box 44610 |
|
| Olympia, Washington 98504-4610 |
| • | Include in your request: |
| – | A copy of the purchaser's written request to the chemical manufacturer, importer, or distributor |
| – | The name of the product suspected of containing a hazardous chemical |
| – | The identification number of the product, if available |
| – | A copy of the product label, if available |
| – | The name and address of the chemical manufacturer, importer, or distributor from whom the product was obtained |
• Maintain a MSDS for each hazardous chemical:
- Keep copies of the required MSDSs for each hazardous chemical present in your workplace. These may be kept in any form, including as a part of operating procedures.
- Each MSDS must be in English. You may also keep copies in other languages.
| Note: |
| • | If you choose not to rely on MSDSs or labels provided by the manufacturer or importer, you must comply
with the chemical hazard communication standard for manufacturers, importers, and distributors, WAC
(( |
| • | It may be more appropriate to address the hazards of a process rather than individual hazardous chemicals. MSDSs can be designed to cover groups of hazardous chemicals in a work area. |
[Statutory Authority: RCW 49.17.010, [49.17].040, and [49.17].050. 01-17-033, § 296-370-55015, filed 8/8/01, effective 9/1/01.]
| Note: | The employer chemical hazard communication information and training requirements also apply to pesticides. Employers who have employees who are exposed to pesticides must be in compliance with this rule and the worker protection standards, WAC 296-307-12040. |
• Provide employees with effective information on hazardous chemicals in their work area at the time of their initial job assignment. Whenever a new physical or health hazard related to chemical exposure is introduced into their employees' work areas, information must be provided.
– Inform employees of:
♦ The requirements of this rule.
♦ Any operations in their work area where hazardous chemicals are present.
♦ The location and availability of your written Chemical Hazard Communication Program, including the list(s) of hazardous chemicals and material safety data sheets (MSDSs) required by this rule.
• Provide employees with effective training about hazardous chemicals in their work area at the time of their initial job assignment. Whenever a new physical or health hazard related to chemical exposure is introduced, the employees must be trained.
• Make sure that employee training includes:
– Methods and observations that may be used to detect the presence or release of a hazardous chemical in the work area. Examples of these methods and observations may include:
♦ Monitoring conducted by you
♦ Continuous monitoring devices
♦ Visual appearance or odor of hazardous chemicals when being released
– Physical and health hazards of the chemicals in the work area, including the likely physical symptoms or effects of overexposure
– Steps employees can take to protect themselves from the chemical hazards in your workplace, including specific procedures implemented by you to protect employees from exposure to hazardous chemicals. Specific procedures may include:
&sqbul; Appropriate work practices
&sqbul; Engineering controls
&sqbul; Emergency procedures
&sqbul; Personal protective equipment to be used
– Details of the Chemical Hazard Communication Program developed by you, including an explanation of the labeling system and the MSDS, and how employees can obtain and use the appropriate hazard information.
• Tailor information and training to the types of hazards to which employees will be exposed. The information and training may be designed to cover categories of hazards, such as flammability or cancer-causing potential, or it may address specific chemicals. Chemical-specific information must always be available through labels and MSDSs.
• Make reasonable efforts to post notices in your employees' native languages (as provided by the department) if those employees have trouble communicating in English.
| Note: |
| • | Interactive computer-based training or training videos can be used provided they are effective. |
| • | Your MSDSs may not have WISHA permissible exposure limits (PELs) listed. In some cases, WISHA PELs
are stricter than the OSHA PELs and other exposure limits listed on the MSDSs you receive. If this is the
case, you must refer to the WISHA PEL table, WAC (( |

• Permissible exposure limits - Short-term exposure limit (PEL-STEL) is the employee's 15-minute time-weighted average exposure which must not be exceeded at any time during a work day unless another time limit is specified in a parenthetical notation below the limit. If another time period is specified, the time-weighted average exposure over that time period must not be exceeded at any time during the working day.
• Permissible exposure limits - Ceiling (PEL-C) is the employee's exposure which must not be exceeded during any part of the work day. If instantaneous monitoring is not feasible, then the ceiling must be assessed as a 15-minute time-weighted average exposure which must not be exceeded at any time over a working day.
• Skin notation is the potential contribution to the overall employee exposure by the cutaneous route including mucous membranes and eye, either by airborne, or more particularly, by direct contact with the substance. These substances are identified as having a skin notation in the OSHA and WISHA PEL tables (29 CFR Part 1910 Subpart Z and WAC 296-62-075, respectively).))

Respirators
NEW SECTION
WAC 296-307-594
Scope.
This part applies to all use of
respirators at work.
IMPORTANT:
Before you decide to use respirators, you are required to evaluate respiratory hazards and implement control methods as outlined in WAC 296-307-624 through 296-307-628, Respiratory hazards.
The term "respiratory hazards" will be used throughout this part to refer to oxygen deficient conditions and harmful airborne hazards.
Definition:
Respirators are a type of personal protective equipment designed to protect the wearer from respiratory hazards.
You can use Table 1 for general guidance on which sections apply to you.
| If employees... | Then the sections marked with an "X" apply... | |||||
| 596 | 598 | 600 | 602-618 | 620 | 622 | |
| Request and are permitted to voluntarily use filtering-facepiece respirators, and are not exposed to a respiratory hazard | X | X | ||||
| Request and are permitted to voluntarily use respirators that are NOT filtering-facepiece respirators, and are not exposed to a respiratory hazard | X | X | X | X | ||
| Are required to use any respirator by WISHA or the employer | X | X | X | X | X | |
| Would use an escape respirator in an emergency | X | X | X | X | X | |
| Reference: | See WAC 296-307-100, Personal protective equipment (PPE) to find requirements for other types of personal protective equipment (PPE), such as eye, hand, and head protection. |
[]
Your responsibility:
To make sure a capable individual is in charge of respirator program development and management.
[]
| Exemption: | You do not need to designate a program administrator if employees use only filtering-facepiece respirators and do so only as voluntary use. |
Voluntary use is respirator use that is requested by the employee AND permitted by the employer when NO respiratory hazard exists.
You must:
• Designate a program administrator who has overall responsibility for your program and has sufficient training or experience to:
– Oversee program development and coordinate implementation
– Conduct required evaluations of program effectiveness outlined in WAC 296-307-60005.
[]
To make sure voluntary use of respirators by employees does not create job safety or health hazards.
You must:
Make sure voluntary use of respirators is safe
Keep voluntary use respirator program records
IMPORTANT:
• Respirator use is NOT voluntary if a respiratory hazard, such as exposure to a substance over the permissible exposure limit (PEL) or hazardous exposure to an airborne biological hazard, is present.
• To evaluate respiratory hazards in your workplace, see WAC 296-307-624, Respiratory hazards.
• Some requirements in this section do not apply if only filtering-facepiece respirators are used voluntarily. Some filtering-facepiece respirators are equipped with a sorbent layer for absorbing "nuisance" organic vapors. These can be used for voluntary use, but are not NIOSH certified for protection against hazardous concentrations of organic vapor.
[]
Definition:
Voluntary use is respirator use that is requested by the employee AND permitted by the employer when NO respiratory hazard exists.
IMPORTANT: If you choose to require respirator use, use is NOT voluntary and the required use sections of this part apply.
You must:
(1) Make sure voluntary respirator use does NOT:
• Interfere with an employee's ability to work safely, such as restricting necessary vision or radio communication
OR
• Create health hazards.
| Note: | Examples of health hazards include: |
| • Skin irritation, dermatitis, or other health effects caused by using a dirty respirator | |
| • Illness created by sharing contaminated respirators | |
| • Health effects caused by use of an unsafe air supply, such as carbon monoxide poisoning. |
(2) Provide all voluntary respirator users with the advisory information in Table 2 at no cost to them.
| Note: | If you have provided employees with the advisory information required in the previous section, WAC 296-307-598, you do not need to provide the additional information in Table 2 to those employees. |
(3) Develop and maintain a written program that includes the following:
• Medical evaluation provisions as specified in WAC 296-307-604.
• Procedures to properly clean and disinfect respirators, according to WAC 296-307-62015, if they are reused.
• How to properly store respirators, according to WAC 296-307-61010, so that using them does not create hazards.
• Procedures to make sure there is a safe air supply, according to WAC 296-307-616, when using air-line respirators and SCBAs.
• Training according to WAC 296-307-608 when necessary to ensure respirator use does NOT create a hazard.
| Note: | • Pay for medical evaluations, training, travel related costs, and wages. You do NOT need to pay for respirators employees use only voluntarily. |
| • If you have both voluntary and required respirator users, you may choose to treat voluntary users as required users. Doing this exceeds the requirements in this section. |
| Exemption: | If employees use only filtering-facepiece respirators and do so only voluntarily, you do not need to develop and maintain a written program. |
Table 2
| Advisory Information for Employees Who Voluntarily Use Respirators | |||
| • Respirators protect against airborne hazards when properly selected and used. WISHA recommends voluntary use of respirators when exposure to substances is below WISHA permissible exposure limits (PELs) because respirators can provide you an additional level of comfort and protection. | |||
| • If you choose to voluntarily use a respirator (whether it is provided by you or your employer) be aware that respirators can create hazards for you, the user. You can avoid these hazards if you know how to use your respirator properly AND how to keep it clean. Take these steps: | |||
| – Read and follow all instructions provided by the manufacturer about use, maintenance (cleaning and care), and warnings regarding the respirator's limitations. | |||
| – Choose respirators that have been certified for use to protect against the substance of concern. The National Institute for Occupational Safety and Health (NIOSH) certifies respirators. If a respirator is not certified by NIOSH, you have no guarantee that it meets minimum design and performance standards for workplace use. | |||
| &sqbul; A NIOSH approval label will appear on or in the respirator packaging. It will tell you what protection the respirator provides. | |||
| – Keep track of your respirator so you do not mistakenly use someone else's. | |||
| – DO NOT wear your respirator into: | |||
| &sqbul; Atmospheres containing hazards that your respirator is not designed to protect against. | |||
| For example, a respirator designed to filter dust particles will not protect you against solvent vapor, smoke or oxygen deficiency. | |||
| &sqbul; Situations where respirator use is required. | |||
[]
| Exemption: | If employees use only filtering-facepiece respirators voluntarily, you do not need to follow these recordkeeping requirements. |
• Keep copies of:
– Your current written respirator program
– Written recommendations from the LHCP
• Allow records required by this section to be examined and copied by affected employees and their representatives.
[]
Your responsibility:
To develop, implement, and maintain a written program that provides clear instruction for safe and reliable respirator use.
You must:
Develop and maintain a written program
Keep respirator program records
[]
| Exemption: | This section does NOT apply to respirator use that is voluntary. See WAC 296-307-59805 for voluntary use program requirements. |
(1) Develop a complete worksite-specific written respiratory protection program that includes the applicable elements listed in Table 3.
| Note: | Pay for respirators, medical evaluations, fit testing, training, maintenance, travel costs, and wages. |
(2) Keep your program current and effective by evaluating it and making corrections. Do ALL of the following:
• Make sure procedures and program specifications are followed and appropriate.
• Make sure selected respirators continue to be effective in protecting employees. For example:
– If changes in work area conditions, level of employee exposure, or employee physical stress have occurred, you need to reevaluate your respirator selection.
• Have supervisors periodically monitor employee respirator use to make sure employees are using them properly.
• Regularly ask employees required to use respirators about their views concerning program effectiveness and whether they have problems with:
– Respirator fit during use
– Any effects of respirator use on work performance
– Respirators being appropriate for the hazards encountered
– Proper use under current worksite conditions
– Proper maintenance.
When developing your written program include applicable elements listed in Table 3.

| &sqbul; Inspection and repair | ||
| &sqbul; When to discard respirators | ||
| – A cartridge or canister change schedule IF air-purifying respirators are selected for use against gas or vapor contaminants AND an end-of-service-life-indicator (ESLI) is not available. In addition, provide: | ||
| &sqbul; The data and other information you relied on to calculate change schedule values (for example, highest contaminant concentration estimates, duration of employee respirator use, expected maximum humidity levels, user breathing rates, and safety factors) | ||
| • Procedures to ensure a safe air quantity and quality IF atmosphere-supplying respirators (air-line or SCBA) are selected | ||
| • Procedures for evaluating program effectiveness on a regular basis | ||
[]
You must:
• Keep the following records:
– Your current respirator program
– Each employee's current fit test record, if fit testing is conducted. Fit test records must include:
&sqbul; Employee name
&sqbul; Test date
&sqbul; Type of fit-test performed
&sqbul; Description (type, manufacturer, model, style, and size) of the respirator tested
&sqbul; Results of fit tests, for example, for quantitative fit tests include the overall fit factor AND a print out, or other recording of the test.
– Training records that include employee's names and the dates trained
– Written recommendations from the LHCP.
• Allow records required by this section to be examined and copied by affected employees and their representatives.
[]
Your responsibility:
To select and provide respirators that are appropriate for the hazard, user, and worksite conditions.
| Exemption: | This section does NOT apply to voluntary respirator use. See WAC 296-307-598 of this part for voluntary use program requirements. |
[]
IMPORTANT:
See WAC 296-307-624, Respiratory hazards, for:
• Hazard evaluation requirements. Evaluation results are necessary for respirator selection.
• A list of substance-specific rules that may also apply to you. Those listed rules have additional respirator selection requirements.
You must:
• Select and provide, at no cost to employees, appropriate respirators for routine use, infrequent use, and reasonably foreseeable emergencies (such as escape, emergency, and spill response situations) by completing the following process:
Step 2: If the respiratory hazard is a biological aerosol, such as TB (tuberculosis), anthrax, psittacosis (parrot fever), or hanta virus, select a respirator appropriate for nonemergency activities recognized to present a health risk to workers AND skip to Step 8.
• If respirator use will occur during emergencies, skip to Step 8 and document the analysis used to select the appropriate respirator.
• Use Centers for Disease Control (CDC) selection guidance for exposures to specific biological agents when this guidance exists. Visit http://www.cdc.gov.
Step 3: If the respiratory hazard is a pesticide, follow the respirator specification on the pesticide label AND skip to Step 9.
Step 4: Determine the expected exposure concentration for each respiratory hazard of concern. Use the results from the evaluation required by WAC 296-307-624, Respiratory hazards.
Step 5: Determine if the respiratory hazard is classified as IDLH; if it is NOT IDLH skip to Step 7.
• The respiratory hazard IS classified as IDLH if:
– The atmosphere is oxygen deficient or oxygen enriched
OR
– You CANNOT measure or estimate your expected exposure concentration
OR
– Your measured or estimated expected exposure concentration is greater or equal to the IDLH value in the NIOSH Pocket Guide to Chemical Hazards
| Note: | • WISHA uses the IDLH values in the 1990 edition of the NIOSH Pocket Guide to Hazardous Chemicals to determine the existence of IDLH conditions. You may use more recent editions of this guide. Visit www.cdc.gov/niosh for more information. |
| • If your measured or estimated expected exposure concentration is below NIOSH's IDLH values, proceed to Step 7. |
OR
• Full-facepiece, pressure demand air-line respirator equipped with an auxiliary self-contained air supply
| Exception: | If the respiratory hazard is oxygen deficiency AND you can show oxygen concentrations can be controlled within the ranges listed in Table 4 under ALL foreseeable conditions, you are allowed to select ANY type of SCBA or air-line respirator. |
Table 4
Concentration Ranges for Oxygen Deficiency
| Altitude (as ft. above sea level) |
Oxygen Concentration Range (as percent oxygen) |
||
| Below 3,001 | 16.0 - 19.5 | ||
| 3,001 - 4,000 | 16.4 - 19.5 | ||
| 4,001 - 5,000 | 17.1 - 19.5 | ||
| 5,001 - 6,000 | 17.8 - 19.5 | ||
| 6,001 - 8,000 | 19.3 - 19.5 | ||
| Above 8,000 feet the exception does not apply. | |||
Step 8: Consider hazards that could require selection of specific respirator types. For example, select full-facepiece respirators to prevent eye irritation or abrasive blasting helmets to provide particle rebound protection.
Step 9: Evaluate user and workplace factors that might compromise respirator performance, reliability or safety.
• If the respiratory hazard is a pesticide, follow the requirements on the pesticide label and skip to Step 11.
Examples:
• High humidity or temperature extremes in the workplace.
• Necessary voice communication.
• High traffic areas and moving machinery.
• Time or distance for escape.
Step 10: Follow Table 6 requirements to select an air-purifying respirator.
• If Table 6 requirements cannot be met, you must select an air-line respirator or an SCBA.
Step 11: Make sure respirators you select are certified by the National Institute for Occupational Safety and Health (NIOSH).
• To maintain certification, make sure the respirator is used according to cautions and limitations specified on the NIOSH approval label.
| Note: | While selecting respirators, you will need to select a sufficient number of types, models or sizes to provide for fit testing. You can also consider other respirator use issues, such as accommodating facial hair with a loose fitting respirator. |

| Note: These respirators are no longer sold for occupational use. | ||
[]
Your responsibility:
To make sure a respirator used under your specific worksite conditions is not a health risk to employees.
| Exemption: | This section does NOT apply to employees who only use: |
| • Filtering-facepiece respirators voluntarily. See WAC 296-307-598 of this part for voluntary use requirements | |
| OR | |
| • Escape-only respirators that are mouthpiece, loose-fitting, or hooded respirators. |
• Using a respirator can create physical risks for an employee each time it is worn. The extent of these risks depends on these factors:
– Type of respirator
– Environmental conditions at the worksite
– Physical demands of the work
– Use of other protective clothing
– Employee's health status.
[]
IMPORTANT:
If you have provided an employee with a medical evaluation addressing respirator use, as required by another chapter, that evaluation will meet the requirements of this section.
You must:
• Follow the medical evaluation process, Steps 1 through 7 in this section, to provide medical evaluations for employees at no cost to them.
• Are required to use respirators
OR
• Voluntarily use respirators that are not filtering-facepiece respirators
| Note: | You may use a previous employer's medical evaluation for an employee if you can: |
| • Show the employee's previous work and use conditions were substantially similar to yours | |
| AND | |
| • Obtain a copy of the licensed healthcare professional's (LHCP's) written recommendation approving the employee's use of the respirator chosen by you. |
| Note: | If you select a different LHCP, you do not need to have new medical evaluations done. |
• Information describing the respirators employees may use, including the weight and type.
• How the respirators will be used, including:
– How often the respirator will be used, for example, daily, or once a month
– The duration of respirator use, for example, a minimum of one hour, or up to twelve hours
– The employee's expected physical work effort

– Temperature and humidity extremes expected during use
• A copy of your written respiratory protection program and this part.
| Note: | • You may choose to send the questionnaire to the LHCP ahead of time, giving time to review it and add any necessary questions |
| • The LHCP determines what questions to add to the questionnaire, if any; however, questions in Parts 1-3 may not be deleted or substantially altered. |
| Note: | You may use on-line questionnaires if the questions are the same and requirements of this section are met. |
– During the employee's normal working hours
OR
– At a time and place convenient to the employee
• Maintain employee confidentiality during examination or questionnaire administration:
– Do not view employee's answers on the questionnaire
– Do not act in a manner that may be considered a breach of confidentiality
| Note: | Providing confidentiality is important for securing successful medical evaluations. It helps make sure the LHCP gets complete and dependable answers on the questionnaire. |
• Provide the employee with an opportunity to discuss the questionnaire or exam results with the LHCP.
Step 5: Provide follow-up evaluation for employees when:
• The LHCP needs more information to make a final recommendation
OR
• An employee gives any positive response to questions 1-8 in Part 2 OR to questions 1-6 in Part 3 of the WISHA medical evaluation questionnaire in WAC 296-307-61605.
| Note: | Follow-up may include: |
| • Employee consultation with the LHCP such as a telephone conversation to evaluate positive questionnaire responses | |
| • Medical exams | |
| • Medical tests or other diagnostic procedures. |
• Whether or not the employee is medically able to use the respirator

| Exemption: | These sections do NOT apply to employees who voluntarily use any type of respirator. See WAC 296-307-598 for voluntary use requirements. |
Prevent sealing problems with tight-fitting respirators
Make sure employees leave the use area before removing respirators
[]
You must:
• Make sure employees use the procedure in WAC 296-307-62020 to perform a user seal check each time they put on their tight-fitting respirator.
• Make sure you do NOT permit respirator use if employees have a characteristic that interferes with the respirator facepiece seal or valve function. For example, stubble, moustaches, sideburns, bangs, hairlines, or scars between the face and the sealing surface of the respirator will affect the seal.
• Make sure corrective glasses or personal protective equipment (PPE) do NOT interfere with the facepiece seal. Examples of PPE include safety glasses, goggles, faceshields, clothing, and hard hats.
[]
You must:
• Make sure employees leave the use area for any of these reasons:

[]
IMPORTANT:
WISHA currently uses the IDLH values in the 1990 NIOSH Pocket Guide to Chemical Hazards to determine the existence of IDLH conditions. You may use more recent editions of this guide. Visit www.cdc.gov/niosh for more information.
You must:
• Provide at least two standby employees outside the IDLH area.
| Note: | You need only one standby employee if the IDLH condition is well characterized, will remain stable AND you can show one employee can adequately do ALL of the following: |
| • Monitor employees in the IDLH area | |
| • Implement communication | |
| • Initiate rescue duties. |
– A pressure-demand SCBA or a pressure-demand air-line respirator with an auxiliary SCBA, for each standby employee
– Appropriate retrieval equipment, when it would help with the effective rescue of the entrant, or an equivalent means of rescue
• Make sure standby employees maintain visual, voice, or signal line communication with employees in the IDLH area
• Make sure that in the event of an emergency:
– Standby employees notify you or your designee before they enter the IDLH area to provide emergency rescue
– You provide necessary assistance when notified.
[]
Your responsibility:
To provide employees who use SCBAs or air-line respirators with an acceptable air supply.
You must:
Make sure breathing air and oxygen meet established specifications
Prevent conditions that could create a hazardous breathing air supply
Make sure compressors do not create a hazardous breathing air supply
[]
You must:
• Make sure that all SCBAs and air-line respirators are provided with safe breathing air and oxygen according to the following:
– Compressed breathing air must meet the following specifications for Grade D air:
&sqbul; Oxygen (volume/volume) within 19.5-23.5%
&sqbul; Hydrocarbon (condensed): NO MORE than five milligrams per cubic meter of air
&sqbul; Carbon monoxide (CO): NO MORE than ten parts per million (ppm)
&sqbul; Carbon dioxide (CO2): NO MORE than 1,000 ppm
&sqbul; No noticeable odor
| Reference: | See the American National Standards Institute - Compressed Gas Association Commodity Specification for Air (G-7.1.1989) for more information. Contact your local library to access a copy. |
• Make sure the moisture content of the air supplied meets the following:
– Air supplied to respirators from cylinders must NOT exceed a dew point of -50°F (or -45.6°C) at 1 atmospheric pressure.
– Compressor supplied air must NOT exceed a dew point of 10°F (or 5.56°C) BELOW the use temperature at 1 atmospheric pressure.
• Cylinders obtained from a supplier of breathing air must have a certificate of analysis that verifies each cylinder's contents meet Grade D and dew point standards.
• Compressed and liquid oxygen must meet the United States Pharmacopoeia requirements for medical or breathing oxygen.
[]
You must:
• Use SCBA and air-line respirators safely:
– Do NOT supply compressed oxygen to SCBAs or air-line respirators that previously used compressed air.
| Note: | Compressed air leaves residues containing hydrocarbons such as oil or grease. Fire or explosion can occur if compressed oxygen makes contact with these residues. |
• Use breathing air couplings on air-line respirators that are NOT compatible with couplings for nonrespirable air or other gas systems, for example, utility air used for manufacturing purposes.
• Do NOT allow asphyxiating substances to enter breathing air lines; for example, do not flush nitrogen through worksite air lines also used for breathing air.
• Use equipment specifically designed for oxygen service or distribution IF oxygen concentrations greater than 23.5% are used.
| Note: | Respiratory equipment NOT designed for oxygen service or distribution can create fire or explosion hazards in oxygen concentrations higher than 23.5%. |
• Make sure cylinders used to supply breathing air for SCBAs or air-line respirators are tested and maintained as described in the federal Department of Transportation's (DOT) Shipping Container Specification Regulations, Title 49 CFR Parts 173 and 178.
| Note: | • Use only cylinders marked (with serial number, cylinder pressure, DOT exemption number, and test dates) according to these DOT regulations |
| • To find any Code of Federal Regulations (CFR) visit: www.access.gpo.gov. |
[]
IMPORTANT:
• Ambient-air movers (or pumps) used to supply air to respirators must be used according to the manufacturer's instructions.
• Respirators used with ambient-air movers must be approved by NIOSH to operate within the pressure ranges of the air mover.
You must:
(1) Locate or modify compressor intakes so they will not pick up contaminated air OR exhaust gases such as carbon monoxide from:
• Fuel-powered vehicles
OR
• The internal combustion motor of the compressor
OR
• Other contaminant sources in the area, for example, a ventilation system discharge.
| Note: | • You may need to reposition or extend the compressor's intake or engine exhaust pipe or outlet, especially if they are located near each other. |
| • Be aware that exhaust gases may not adequately disperse when the compressor is operated in: | |
| – An enclosed space such as a small room, a corner, or near a wall | |
| OR | |
| – In turbulent wind conditions. |
(2) Equip compressors with suitable air-purifying filters, water traps, and sorbents (such as charcoal beds) and maintain them as follows:
• Periodically change or clean them according to the manufacturer or supplier's instructions
• Keep a tag at the compressor with the following information:
– When the sorbent and filters were last replaced or cleaned
– The date of the most recent changes or cleaning
– The signature of the person authorized by the employer to perform changes or cleaning.
| Note: | To be sure you are providing the recommended operating pressure for respirators, you may need to install a delivery pressure gauge at the point where the manifold respirator hose is attached. |
(3) Make sure the carbon monoxide (CO) level in breathing air from compressors does NOT exceed ten parts per million (ppm).
| Note: | If you do not have a reliable CO-free area available for locating your compressor intake, consider these examples of methods to prevent CO contamination of the air supply: |
| • Use of continuous and effective carbon monoxide alarms and filters | |
| • Conduct frequent monitoring of air quality | |
| • Use a CO converter (converts CO to carbon dioxide). |
• Maintain CO levels in oil lubricated compressors by using at least one of the following:
– An effective CO alarm
– An effective high temperature alarm AND testing the air supply often enough to see if CO levels exceed ten ppm.
| Note: | • How often to test depends on a number of considerations, for example: |
| – Compressor age | |
| – Maintenance history of the compressor | |
| – Stability of CO readings | |
| • If the CO or high temperature alarm cannot be heard by the employee, a flashing light or other effective alternative to an audio alarm needs to be used | |
| • Safeguards, such as alarms, are necessary to prevent CO contamination resulting from compressor overheating | |
| • Any type of oil-lubricated compressor, such as screw or piston types, may produce dangerous levels of CO if overheating occurs | |
| – Old compressors are known to leak oil due to worn parts, increasing the possibility for overheating. Newer compressors may also overheat if maintenance practices are poor. For example, poor maintenance practices may lead to disconnected or incorrectly set alarms, inoperative shut-offs, or an impaired cooling system | |
| • You need to instruct employees to move to a safe area when the alarm sounds AND to stop using respirators. |
[]
Your responsibility:
To make sure employees, their supervisors, and program administrators can easily check for the correct air-purifying filters, cartridges, and canisters on respirators.

IMPORTANT:
• This section contains procedural requirements that apply during actual fit testing.
• See WAC 296-307-606 of this part for fit-testing requirements that apply to your overall program.
| Exemptions: | This section does NOT apply to employees who: |
| • Voluntarily use respirators | |
| OR | |
| • Are required to use mouthpiece respirators. |
• Conduct fit testing according to all of the following:
– Follow the procedure in Table 11 to choose a respirator for fit testing:
&sqbul; Prior to conducting fit tests
AND
&sqbul; Any time your employee must select a different respirator such as when a previously selected respirator fails a test
– Select and follow at least one of the following fit test procedures:
&sqbul; Qualitative fit-test procedures:
♦ Isoamyl acetate vapor (IAA, banana oil) in Table 12
♦ Saccharine aerosol in Table 13
♦ Bitrex™ aerosol in Table 14
♦ Irritant smoke in Table 15
&sqbul; Quantitative fit-test procedures:
♦ Ambient aerosol condensation nuclei counter such as the Portacount™, in Table 16

♦ Generated aerosol in Table 18
– Make sure employees perform the appropriate fit-test exercises listed in Table 19.
– Clean and maintain equipment according to the manufacturer's instructions.
– Make sure during fit testing employees wear any safety equipment that could:
&sqbul; Interfere with respirator fit
AND
&sqbul; Be worn in the workplace. For example, chemical splash goggles.
– Check, prior to fit testing, for conditions that may interfere with the respirator seal or valve functions. If you find such conditions, do NOT conduct fit testing for that individual.
| Note: | Examples of conditions that may interfere with the respirator seal or valve functions include: |
| • Moustache, stubble, sideburns, bangs, hairline, and other types of facial hair in areas where the respirator facepiece seals or that interfere with valve function | |
| • Temple bars of corrective eyewear or headgear that extend through the face seal area. |
Table 11
| Procedure for Choosing a Respirator for Fit Testing | |||
| 1. Inform the employee: | |||
| • To choose the most comfortable respirator that provides an adequate fit | |||
| • That each respirator sample represents a different size and, if more than one model is supplied, a different shape | |||
| • That if fitted and used properly, the respirator chosen will provide adequate protection | |||
| 2. Provide a mirror and show the employee how to: | |||
| • Put on the respirator | |||
| • Position the respirator on the face | |||
| • Set strap tension. | |||
| Note: This instruction does NOT take the place of the employee's formal training since it is only a review. |
|||
| 3. Review with the employee how to check for a comfortable fit around the nose, cheeks and other areas on the face. | |||
| • Tell the employee the respirator should be comfortable while talking or wearing eye protection. | |||
| 4. Have the employee hold each facepiece against the face, taking enough time to compare the fit of each. The employee can then either: | |||
| • Reject any facepiece that clearly does not feel comfortable or fit adequately | |||
| OR | |||
| • Choose which facepiece is most acceptable and which is less acceptable, if any. | |||
| Note: • Supply as many respirator models and sizes as needed to make sure the employee finds a respirator that's acceptable and fits correctly • To save time later, during this step note the more acceptable facepieces in case the one chosen fails the fit test or proves unacceptable later. |
|||
| 5. Have the employee wear the most acceptable respirator for AT LEAST 5 minutes to evaluate comfort and fit. Do ALL of the following during this time: | |||
| • Ask the employee to observe and comment about the comfort and fit: | |||
| – Around the nose, cheeks, and other areas on the face | |||
| – When talking or wearing eye protection | |||
| • Have the employee put on the respirator and adjust the straps until they show proficiency | |||
| • Evaluate the respirator's general fit by checking: | |||
| – Proper chin placement | |||
| – Properly tightened straps (do NOT over tighten) | |||
| – Acceptable fit across the nose bridge | |||
| – Respirator size; it must span the distance from nose to chin | |||
| – To see if the respirator stays in position | |||
| • Have the employee complete a successful seal check as specified in WAC 296-307-62020 of this chapter | |||
| – Prior to the seal check they must settle the respirator on their face by taking a few slow deep breaths WHILE SLOWLY: | |||
| &sqbul; Moving their head from side-to-side | |||
| AND | |||
| &sqbul; Up and down. | |||
| 6. If the employee finds the respirator unacceptable, allow the employee to select another one and return to Step 5. Otherwise, proceed to Step 7. | |||
| 7. Before starting the fit test, you must: | |||
| • Describe the fit test including screening procedures, employee responsibilities, and test exercises | |||
| AND | |||
| • Make sure the employee wears the respirator AT LEAST five minutes. | |||
Table 12
| Isoamyl Acetate (Banana Oil) Vapor Test Procedure | ||||
| Important: | ||||
| • This is a qualitative fit-test (QLFT) procedure | ||||
| • The success of this test depends on preserving the employee's odor sensitivity to isoamyl acetate (IAA) vapor | ||||
| – Vapor accumulations in ambient air can decrease odor sensitivity. To prevent this: | ||||
| &sqbul; Prepare ALL solutions in a location separate from screening and test areas | ||||
| &sqbul; Conduct screening and tests in separate well-ventilated rooms. For example, use an exhaust fan or laboratory hood to prevent IAA vapor from accumulating in the room air | ||||
| – Always use odor-free water, for example, distilled or spring water that's 25°C (77°F). | ||||
| • Isoamyl acetate is also known as isopentyl acetate. | ||||
| Screening Preparations | ||||
| Important: | ||||
| Odor threshold screening determines if the employee can detect weak concentrations of IAA vapor. | ||||
| 1. Choose an appropriate location to conduct screening. | ||||
| • Conduct screening and tests in separate well-ventilated rooms. | ||||
| 2. Prepare a stock solution AT LEAST weekly as follows: | ||||
| • Add one milliliter (ml) of pure IAA to 800 ml of odor-free water in a one-liter glass jar with a metal lid using a measuring dropper or pipette | ||||
| • Seal the jar with the lid and shake it for 30 seconds | ||||
| • Clean the dropper or pipette. | ||||
| 3. Prepare the odor test solution daily as follows: | ||||
| • Add 0.4 ml from the stock solution to 500 ml of water in a one liter glass jar with a metal lid using a clean pipette or dropper | ||||
| • Seal the jar with the lid and shake it for 30 seconds | ||||
| • Let this solution stand for 2-3 minutes so the IAA concentration above the liquid reaches equilibrium | ||||
| • Label this jar so you know the contents but the employee cannot know its contents, for example, "1." | ||||
| Note: To maintain the integrity of the test, use labels that peel off easily AND periodically switch the labels. |
||||
| 4. Prepare a "test blank" solution as follows: | ||||
| • Add 500 ml of odor-free water to a one liter glass jar with a metal lid | ||||
| • Seal the jar | ||||
| • Label the jar so you know the contents but the employee cannot know its contents. | ||||
| 5. Type or neatly print the following instructions on a card and place it on the table in front of the two test jars: | ||||
| "The purpose of this test is to find out if you can smell banana oil at a low concentration. While both jars contain water, one ALSO contains a small amount of banana oil. | ||||
| Make sure the lid is secure then pick up a jar and shake it for two seconds. Open the jar and sniff at the opening. Repeat this for the second jar. | ||||
| Tell the individual conducting the fit test which jar contains banana oil." | ||||
| Test Preparations | ||||
| 6. Choose an appropriate location to conduct fit testing. | ||||
| • Conduct screening and tests in separate well-ventilated rooms. | ||||
| 7. Assemble the fit test enclosure in the room. | ||||
| • Invert a clear 55-gallon drum liner over a circular 2-foot diameter frame made of plywood or other lightweight rigid material OR construct a similar enclosure using plastic sheeting | ||||
| • Hang the frame with the plastic covering so the top of the enclosure is about six inches above the employee's head | ||||
| • Attach a small hook inside top center of the enclosure | ||||
| • Tape a copy of the test exercises (see Table 28) to the inside of the test enclosure where the employee can read it. | ||||
| 8. Have organic vapor cartridges or equivalent on hand for each employee's chosen respirator. | ||||
| 9. Have ready a 6 x 5-inch piece of paper towel or other porous absorbent single-ply material AND 0.75 ml of pure IAA. Do NOT apply IAA yet. | ||||
| Note: As an alternative to using the paper towel, you may use an IAA test swab OR ampoule if it has been demonstrated to generate an equivalent test concentration. |
||||
| Screening | ||||
| 10. Have the employee, while NOT wearing a respirator, follow the instructions on the card provided. | ||||
| • If the employee correctly identifies the jar containing IAA, proceed to conduct testing (Step 11) | ||||
| • If the employee is NOT able to correctly identify the jar containing IAA, you must STOP and use a different fit test protocol. | ||||
| Test | ||||
| 11. BEFORE entering the fit test room, have the employee attach cartridges, put on, properly adjust, and seal check the respirator. Have the employee enter the test enclosure. | ||||
| 12. Wet the paper towel with 0.75 ml of pure IAA AND fold it in half. | ||||
| 13. Pass the paper towel to the employee inside the enclosure AND instruct the employee to hang it on the hook at the top of the enclosure. | ||||
| 14. Wait two minutes for the IAA vapor to fill the enclosure. | ||||
| • While waiting, explain the fit test, including the purpose of the test exercises, the importance of cooperation, and that you must be informed if a banana-like odor is detected during the test | ||||
| • You may also demonstrate the test exercises. | ||||
| 15. Have the employee perform the appropriate fit-test exercises in Table 19. | ||||
| • If the employee does NOT detect IAA while performing test exercises, the fit test has been PASSED. Proceed as follows: | ||||
| – BEFORE leaving the enclosure, have the employee break the respirator seal and inhale. If they detect IAA, the test is valid | ||||
| – When exiting the employee must remove the paper towel and give it to the individual conducting the fit test. This prevents IAA vapor from building up in the enclosure during subsequent tests | ||||
| – The individual conducting the fit test must keep used paper towels in a self-sealing plastic bag to prevent area contamination | ||||
| • If the employee detects IAA during any test exercise, the fit test has FAILED. STOP and have the employee do the following: | ||||
| – Quickly return to the selection room to remove the respirator. This avoids decreasing the employee's odor sensitivity | ||||
| – Select another respirator | ||||
| – Repeat screening and testing | ||||
| &sqbul; At this stage, if the employee fails the screening part of this procedure, the employee can repeat it AFTER waiting at least five minutes for odor sensitivity to return. | ||||
Table 13
| Saccharin Aerosol Test Procedure | ||||
| Screening Preparations | ||||
| Important: | ||||
| • This is a qualitative fit-test (QLFT) procedure | ||||
| • Taste threshold screening determines whether the employee being tested can detect the taste of saccharin | ||||
| – The employee must NOT eat, smoke, chew gum or drink anything but plain water for at least fifteen minutes BEFORE the fit test. Sweet foods or drink consumed before the test may make the employee unable to detect saccharin during screening | ||||
| – Nebulizers must be thoroughly rinsed in water and shaken dry: | ||||
| &sqbul; Each morning and afternoon | ||||
| OR | ||||
| &sqbul; At least every four hours. | ||||
| • You may use commercially prepared solutions if they meet the requirements in this procedure. | ||||
| 1. Obtain a test enclosure (hood) that meets the following specifications: | ||||
| • Twelve inches in diameter by fourteen inches tall | ||||
| • A clear front portion | ||||
| • Enough space inside to allow free movement of the head when a respirator is worn | ||||
| • A 3/4 inch (or 1.9 centimeter) hole to accommodate the nebulizer nozzle. The hole must line up in front of the wearer's nose and mouth. | ||||
| Note: • An enclosure similar to the 3M hood assembly, parts #FT 14 and #FT 15 combined, meets these specifications • This enclosure can also be used for testing. |
||||
| 2. Obtain and assemble two clean DeVilbiss Model 40 Inhalation Medication Nebulizers OR equivalent. | ||||
| 3. Prepare the screening solution as follows: | ||||
| • Dissolve 83.0 milligrams of sodium saccharin USP in 100 ml of warm distilled water | ||||
| OR | ||||
| • IF you have already prepared the fit-test solution, you can make the screening solution by adding 1 ml of this solution to 100 ml of distilled water. | ||||
| 4. Add about 1 ml of the screening solution to one of the nebulizers. | ||||
| • Mark this nebulizer to distinguish it from the one to be used for fit testing. | ||||
| Test Preparations | ||||
| 5. Prepare the fit-test solution as follows: | ||||
| • Add 83.0 grams of sodium saccharin to 100 ml of warm water. | ||||
| 6. Add about 1 ml of the test solution to the second nebulizer. | ||||
| • Mark this nebulizer to distinguish it from the one used for screening | ||||
| 7. Have particulate filters ready for the employee's chosen respirator or have filtering-facepiece respirators ready. | ||||
| Screening | ||||
| 8. Have the employee, while NOT wearing a respirator, put on the test enclosure. | ||||

| • Breath through a slightly open mouth with tongue extended during screening AND testing | ||||
| • Immediately report when a sweet taste is detected. | ||||
| 10. Insert the nebulizer into the front hole of the test enclosure AND administer saccharin as follows: | ||||
| • Direct the nozzle away from the employee's nose and mouth | ||||
| • Complete 10 squeezes in rapid succession | ||||
| • Each time firmly squeeze the bulb so it collapses completely, then release and allow it to fully expand. | ||||
| 11. Ask the employee if a sweet taste is detected. | ||||
| • If YES, screening is completed. Proceed to conduct testing, Step 14, AFTER you: | ||||
| – Ask the employee to remember the taste for reference during the fit test | ||||
| – Note the employee's taste threshold as "10" regardless of the number of squeezes actually completed | ||||
| • If NO, screening must continue. Proceed to Step 12. | ||||
| 12. Repeat with 10 more squeezes. Then follow Step 11 again; EXCEPT this time note the employee's taste threshold as "20" IF a sweet taste is reported. | ||||
| • If a sweet taste is still NOT detected, repeat with 10 more squeezes and follow Step 11 one last time; EXCEPT this time note "30" for the taste threshold IF a sweet taste is reported. | ||||
| 13. If NO sweet taste is reported after 30 squeezes, you must STOP and choose a different fit-test protocol for the employee. | ||||
| Test | ||||
| Important! | ||||
| • Periodically check nebulizers to make sure they do not clog during use. A test is NOT valid if the nebulizer is clogged at the end of the test. | ||||
| 14. Have the employee attach particulate filters, put on, properly adjust, and seal check the respirator. Have the employee put on the test enclosure (hood). | ||||
| 15. Instruct the employee to immediately report if a sweet taste is detected. | ||||
| 16. Insert the nebulizer into the front hole of the test enclosure AND administer the same number of squeezes, either 10, 20, or 30, as noted during screening. | ||||
| 17. Have the employee perform the appropriate fit-test exercises as described in Table 19. During this step: | ||||
| • Replenish the aerosol in the hood EVERY 30 seconds using 1/2 the number of squeezes used in Step 16, either 5, 10, or 15 | ||||
| • The employee must report if a sweet taste is detected: | ||||
| – If NO saccharin is tasted, the test has been PASSED | ||||
| &sqbul; If saccharin is tasted the test has FAILED, have the employee select another respirator | ||||
| AND | ||||
| &sqbul; Repeat screening and testing. | ||||

Table 15
| Irritant Smoke (Stannic Chloride) Test Procedure | ||
| Important: | ||
| • DO NOT USE A TEST ENCLOSURE OR HOOD FOR THIS FIT TEST! | ||
| • This is a qualitative fit-test (QLFT) procedure | ||
| • During this test an employee is exposed to irritating smoke containing hydrochloric acid produced by a stannic chloride ventilation smoke tube to detect leakage. The smoke will irritate eyes, lungs, and nasal passages | ||
| • Employee sensitivity varies, and certain employees may respond more intensely than others exposed to irritant smoke. The individual conducting the fit test must take precautions to minimize the employees' exposure to irritant smoke | ||
| • Conduct fit testing in an area with adequate ventilation to prevent exposure of the individual conducting the fit test and build-up of irritant smoke in the ambient air. | ||
| Screening AND Test Preparations | ||
| Important: | ||
| Sensitivity screening is necessary to determine whether the employee can detect a weak concentration of irritant smoke AND whether any gross facepiece leakage is detected. | ||
| 1. Obtain only stannic chloride (ventilation) smoke tubes, AND an aspirator squeeze bulb OR use a low-flow air pump set to deliver 200 milliliters of air flow per minute. | ||
| 2. Equip the employee's chosen respirator with P100 series filters if a negative pressure air-purifying respirator will be tested. If a powered air-purifying respirator (PAPR) will be tested equip the respirator with high-efficiency particulate air (HEPA) filters. | ||
| Screening | ||
| Important! | ||
| When performing sensitivity screening checks use only the MINIMUM amount of smoke necessary to elicit a response from the employee. | ||
| 3. Advise the employee that the smoke can be irritating to eyes, lungs, and nasal passages AND instruct the employee to keep eyes closed while exposed. | ||
| 4. Break both ends of the ventilation smoke tube AND fit a short piece of plastic tubing, for example, two-to-six inches of tygon tubing, over one end to prevent exposure to the sharp end of the tube. Connect the other end to an aspirator bulb or a low-flow air pump set to deliver a flow of 200 ml per minute. | ||
| 5. While the employee is NOT wearing a respirator, have the employee smell a weak concentration of irritant smoke to become familiar with its irritating properties. | ||
| • Carefully direct a small amount of irritant smoke toward the employee. | ||
| Test | ||
| Test 6. Have the employee attach respirator filters, put on, adjust, and seal check the respirator without assistance. The employee must be proficient at these tasks. | ||
| 7. Remind the employee to keep eyes closed during testing. | ||
| 8. Direct a stream of irritant smoke toward the respirator's face seal area as follows: | ||
| • Begin at least 12 inches from the facepiece AND move the smoke around the whole perimeter of the mask | ||
| • Gradually make two more passes around the perimeter of the facepiece, moving to within 6 inches of the respirator | ||
| • STOP at any time the employee detects smoke in the facepiece. If this occurs a different respirator will need to be chosen and tested, beginning with sensitivity screening. | ||
| 9. Have the employee perform appropriate fit-test exercises in Table 19 IF the employee has NOT had an involuntary response such as evidence of coughing, flinching, or other response, OR detected smoke in the facepiece. | ||
| • Continue to direct smoke from a distance of 6 inches around the facepiece perimeter | ||
| – If smoke is detected at any time the test has FAILED. A different respirator must be chosen and tested, starting with sensitivity screening | ||
| – If NO smoke is detected proceed to Step 10. | ||
| 10. Have the employee remove the respirator AND perform another sensitivity screening check as follows: | ||
| • Continue to use the smoke tube used for fit testing | ||
| • Carefully direct a SMALL amount of irritant smoke toward the employee | ||
| – The test has been PASSED IF the employee responds to the smoke | ||
| – The fit test is VOIDED IF the employee does NOT respond to the smoke. | ||
Table 16
| Ambient Aerosol Condensation Nuclei Counter (Portacount™) Test Procedure | |||
| Important: | |||
| • This is a quantitative (QNFT) fit-test procedure | |||
| • This method uses a particle counting instrument that measures and compares the particle concentration both inside and outside the respirator facepiece while the employee performs a series of test exercises | |||
| • Particles in the ambient air are used as the test aerosol. | |||
| Test Preparations | |||
| 1. Obtain a test instrument such as a Portacount™. | |||
| 2. Have probed respirators available for each respirator model and size the employer uses, OR have a sampling adapter available if the employee's actual or chosen respirator will be tested. | |||
| Note: • A probed respirator has a special fitting installed on the facepiece designed to connect with the end of the test instrument's plastic sampling tube so that air samples can be taken inside the facepiece. Probed respirators can be obtained from the respirator manufacturer, or distributor, AND can only be used for fit-testing purposes • Contact TSI Inc., OR the respirator's manufacturer to obtain probed respirators or facepiece sampling adapters. |
|||
| 3. Follow the test instrument manufacturer's instructions for test preparation, including particle, zero, and system checks. Make sure the instrument's pass OR fail criterion is programmed to the following MINIMUM performance levels: | |||
| • For half-facepiece respirators, an overall minimum fit factor of 100 as a passing level | |||
| • For full-facepiece respirators, an overall minimum fit factor of 500 as a passing level | |||
| 4. Have high-efficiency particulate air (HEPA) filters, OR other respirator filters available that are capable of preventing significant penetration by particles generated by the test instrument such as, P100 or N95 series filters. | |||
| • If you'll use a sampling adapter instead of probed respirators be sure to have the correct type for the respirators chosen. | |||
| Test | |||
| 5. Properly attach the sampling line to the facepiece probe or sampling adapter. | |||
| 6. Have the employee attach respirator filters, put on, properly adjust, and wear the respirator five minutes BEFORE the fit test. During this time you and the employee must evaluate the respirator's general fit by checking: | |||
| • Proper chin placement | |||
| • Properly tightened straps (do NOT over tighten) | |||
| • Acceptable fit across the nose bridge | |||
| • Respirator size. It must span the distance from nose to chin | |||
| • To see if the respirator stays in position. | |||
| Note: Wearing the respirator for five minutes permits the employee to make certain the respirator is comfortable AND allows for purging of ambient particles trapped inside the facepiece. |
|||
| 7. Have the employee perform a seal check. Make sure the sampling line is crimped to avoid leakage during the seal check. If NO leakage is detected, proceed to Step 8. If leakage is detected: | |||
| • Determine the cause | |||
| AND | |||
| • If leakage is due to a poorly fitting facepiece, have the employee: | |||
| – Choose another respirator size or model | |||
| AND | |||
| – Start again at Step 6. | |||
| 8. Start the fit test cycle. | |||
| • Follow the manufacturer's instructions for operating the test instrument | |||
| • Have the employee perform the appropriate fit-test exercises in Table 19 | |||
| – The test instrument will automatically stop and calculate the overall fit factor. Use this result to determine whether or not the test is passed | |||
| &sqbul; The test has been PASSED if the overall fit factor is at least 100 for a half facepiece, OR 500 for a full facepiece | |||
| &sqbul; The test has FAILED if the overall fit factor is below 100 for a half facepiece or 500 for a full facepiece. | |||
| Note: If the test has failed, have the employee select another respirator model or size following Table 11 AND repeat this procedure. |
|||
Table 17
| Controlled Negative Pressure (CNP) Test Procedure | ||
| Important! | ||
| • This is a quantitative fit-test (QNFT) procedure | ||
| • This method determines respirator fit by measuring how much the facepiece leaks when it is subject to a slight negative pressure AFTER various premeasurement activities | ||
| • Measurements occur while employees remain still AND hold their breath for 10 seconds | ||
| • No test aerosols are used. Respirator cartridges aren't needed for this test. | ||
| Test Preparations | ||
| 1. Make sure the individual conducting the fit test is thoroughly trained to perform this test. | ||
| 2. Obtain a CNP test instrument such as a FitTester 3000™. Make sure: | ||
| • Defaults are set at: | ||
| – -15mm (-0.58 inches) of water test pressure | ||
| AND | ||
| – A modeled inspiratory flow rate of 53.8 liters per minute | ||
| • It has an effective audio warning device that signals when employees fail to hold their breath. | ||
| Note: • You are not required to obtain test recording and printing equipment such as computers OR printers. Hand recording results is acceptable • To see default settings, check the instrument's "REDON protocol." |
||
| 3. Obtain facepiece adapters appropriate for each test respirator. | ||
| Note: • Adapters are either a one-piece (for SCBA facepieces), OR two-piece (for dual cartridge facepieces) device providing a manifold and breathing valve system. For positive pressure respirators, you will need to obtain an additional fitting, available from the respirator manufacturer, to convert the facepiece to negative pressure • To obtain adapters, contact the CNP instrument's distributor, Occupational Health Dynamics, OR the respirator manufacturer. |
||
| Test | ||
| Important! | ||
| After the test, you must ask the employee about the comfort of the respirator AND if the respirator has become unacceptable, another size or model must be chosen and tested. | ||
| 4. Explain the test procedure to the employee. | ||
| 5. Train the employee on how to hold a breath for at least 20 seconds. | ||
| 6. Prepare the respirator for the fit test as follows: | ||
| • Remove or prop open the inhalation valves. If a breathing tube is present, disconnect it | ||
| • Replace cartridges, if present, with the manifold and breathing valve adapter | ||
| – For positive pressure facepieces, mount the manufacturer's additional fitting followed by the manifold-breathing valve adapter | ||
| • Connect the respirator to the CNP device according to the CNP instrument manufacturer's directions. | ||
| 7. Have the employee put on, adjust, and seal check the respirator. | ||
| 8. Turn on the instrument AND have the employee stand and perform the fit-test exercises in Table 19. | ||
| 9. Interpret the test results: | ||
| • The test is PASSED IF the overall fit factor obtained is at least 100 for a half facepiece, or at least 500 for a full facepiece | ||
| • The test has FAILED IF the fit factor is less than 100 for a half facepiece; 500 for a full facepiece | ||
| – If the test has FAILED you must have the employee select another respirator model or size following the steps in Table 11 AND repeat this procedure, starting at Step 6. | ||
Table 18
| Generated Aerosol Test Procedure | ||||||||
| Important: | ||||||||
| • This is a quantitative (QNFT) fit-test procedure | ||||||||
| • In this method, a test aerosol is used to challenge the facepiece seal while aerosol concentrations inside and outside the facepiece are measured during test exercises | ||||||||
| • Special equipment is needed to generate, disperse, detect, and measure test aerosols. | ||||||||
| Test Preparations | ||||||||
| 1. Test aerosol. | ||||||||
| • Use a particulate, for example, corn oil, polyethylene glycol 400, di-2-ethyl hexyl sebacate, or sodium chloride. | ||||||||
| 2. Instrumentation. | ||||||||
| • Do ALL the following: | ||||||||
| – Obtain and use aerosol generation, dilution, and measurement systems appropriate for particulates | ||||||||
| – Use an aerosol-generating instrument that will maintain test concentrations within a 10% variation | ||||||||
| – Select a sampling instrument that allows for a computer record or strip chart record to be created | ||||||||
| &sqbul; The record must show the rise and fall of test agent concentration during each inhalation and exhalation at fit factors of at least 2000. | ||||||||
| Note: Integrators, or computers that integrate the amount of test agent penetration leakage into the respirator for each exercise, may be used if a record of the readings is made. | ||||||||
| – Minimize the time interval between the activity and the recording of the activity so you can clearly connect what you see to what is being recorded. For example, use a small diameter and length of sampling line. | ||||||||
| 3. Test enclosure. | ||||||||
| • Do ALL the following: | ||||||||
| – Make sure the enclosure is equipped and constructed to effectively: | ||||||||
| &sqbul; Maintain a uniform concentration of the test agent inside the enclosure. For example, the enclosure must be large enough to allow ALL employees freedom of movement during testing WITHOUT disturbing the test concentration or measurement instrument | ||||||||
| &sqbul; Keep the test agent from contaminating the air outside the enclosure. For example, use a HEPA filter to purify exhausted air | ||||||||
| &sqbul; Allow the individual conducting the fit test to view the employee during the test | ||||||||
| – Make sure the tubing used to collect samples from the enclosure AND respirator is the same material, diameter, AND length. This makes the effect of aerosol loss caused by deposition in each sample line equal | ||||||||
| – If sodium chloride is used, relative humidity inside the enclosure must be kept below 50%. | ||||||||
| 4. Prepare test respirators. | ||||||||
| • Do ALL the following: | ||||||||
| – Inspect test respirators regularly for missing parts AND damage | ||||||||
| – Keep test respirators in proper working order | ||||||||
| – Make sure in-mask sampling probes are: | ||||||||
| &sqbul; Designed and installed so the air sample will be drawn from the employee's breathing zone; midway between the nose and mouth | ||||||||
| AND | ||||||||
| &sqbul; The probe extends inside the facepiece at least 1/4 inch | ||||||||
| – Make sure sampling ports such as probes, or adapters on respirators are constructed and installed so they do NOT: | ||||||||
| &sqbul; Block air flow into the sampling line | ||||||||
| &sqbul; Leak | ||||||||
| &sqbul; Interfere with the respirator's fit or performance | ||||||||
| • Have high efficiency particulate air (HEPA) filters OR P100 series filter available | ||||||||
| – Replace filters when increased breathing resistance is detected OR when the test agent has altered the filter material's integrity. | ||||||||
| Test | ||||||||
| Important! | ||||||||
| • Throughout the test, maintain the employee's exposure to any test agent below the established exposure limit. Exposures allowed must be based on exposure time and exposure limit duration | ||||||||
| • If a single peak penetration exceeds 5% for half facepieces OR 1% for full facepieces: | ||||||||
| – STOP the test | ||||||||
| AND | ||||||||
| – Have the employee select another respirator for testing. | ||||||||
| 5. Have the employee attach filters, put on, adjust, and seal check the respirator. | ||||||||
| • Be sure to crimp the sampling line to avoid pressure leaks during the seal check | ||||||||
| AND | ||||||||
| • Have the employee adjust the respirator straps, without assistance, so the fit is comfortable. Do NOT over tighten. | ||||||||
| 6. OPTIONAL Step. To save time conduct a screening test to quickly identify poorly fitting respirators. | ||||||||
| Note: You may use a qualitative screening test OR an ambient aerosol condensation nuclei counter instrument in the count mode. | ||||||||
| 7. Make sure test aerosol concentration is reasonably stable. | ||||||||
| • If a canopy or shower curtain enclosure is used, determine stability of the test aerosol concentration AFTER the employee enters the enclosure. | ||||||||
| 8. Have the employee enter the test enclosure and connect the respirator to the sample lines. | ||||||||
| 9. Immediately after entering the enclosure measure test aerosol concentration inside the respirator. | ||||||||
| • Make sure the peak penetration does NOT exceed 5% for half facepieces, OR 1% for full facepieces. | ||||||||
| 10. Have employee perform the appropriate fit-test exercises in Table 19. | ||||||||
| • Do NOT adjust the respirator once exercises begin. | ||||||||
| 11. Calculate the overall fit factor as specified in Steps 12-13. The fit test is: | ||||||||
| • PASSED IF the minimum fit factor of 100 for half facepieces OR 500 for full facepieces is obtained | ||||||||
| OR | ||||||||
| • IF a passing fit factor is NOT obtained, the test has FAILED and you must have the employee select and test another respirator. | ||||||||
| Calculations | ||||||||
| Important! | ||||||||
| • Do NOT count the grimace exercise measurements during these calculations | ||||||||
| • Take into account the limitations of instrument detection when determining fit factors. | ||||||||
| 12. Calculate individual fit factors for EACH exercise by applying the following: | ||||||||
| Exercise fit factor (ffE) = Average test enclosure concentration | ||||||||
| Test aerosol concentration inside the respirator | ||||||||
| • To determine the average test enclosure concentration use one of the following methods: | ||||||||
| – Arithmetic average of the concentration before and after each test (an average of two values per entire test) | ||||||||
| – Arithmetic average of concentration before and after each exercise (an average of two values per exercise) | ||||||||
| – True average measured continuously during the respirator sample | ||||||||
| • Determine the test aerosol concentration inside the respirator in one of the following ways: | ||||||||
| – Average peak penetration values. Determine aerosol penetration for each exercise by: | ||||||||
| &sqbul; Using integrators or computers that calculate the actual test agent penetration | ||||||||
| OR | ||||||||
| &sqbul; Average the peak heights shown on the strip chart recording, graph, or by computer integration | ||||||||
| – Maximum peak penetration. Use strip chart recordings to determine the highest peak penetration for each exercise and use this value | ||||||||
| – Area under the peaks. Use computerized integration or other appropriate calculations to integrate the area under individual peaks for each exercise. | ||||||||
| 13. Using individual exercise fit factors (ffE) calculate the overall fit factor by doing ALL of the following: | ||||||||
| • Convert each exercise fit factor to a penetration value | ||||||||
| • Determine the average penetration value | ||||||||
| • Convert the average penetration value back to a fit factor | ||||||||
| OR | ||||||||
| • Use this equation to calculate the overall fit factor: | ||||||||
| Overall fit factor = | n | |||||||
| 1/ffE1 + 1/ffE2 + 1/ffE3. . . + 1/ffEn | ||||||||
Table 19

| "When the sunlight strikes raindrops in the air, they act like a prism and form a rainbow. The rainbow is a division of white light into many beautiful colors. These take the shape of a long round arch, with its path high above, and its two ends apparently beyond the horizon. There is, according to legend, a boiling pot of gold at one end. People look, but no one ever finds it. When a man looks for something beyond reach, his friends say he is looking for the pot of gold at the end of the rainbow." |

You must:
• Follow the procedure in Table 20 for cleaning and disinfecting respirators.
Table 20
Respirator Cleaning Procedure
| Step | Task | |||
| 1. | Remove filters, cartridges, canisters, speaking diaphragms, demand and pressure valve assemblies, hoses, or any components recommended by the manufacturer. | |||
| • Discard or repair any defective parts. | ||||
| 2. | Wash components in warm (43°C (110°F) maximum) water with a mild detergent or with a cleaner recommended by the manufacturer | |||
| • A stiff bristle (not wire) brush may be used to help remove the dirt | ||||
| • If the detergent or cleaner does not contain a disinfecting agent, respirator components should be immersed for two minutes in one of the following: | ||||
| – A bleach solution (concentration of 50 parts per million of chlorine). Make this by adding approximately one milliliter of laundry bleach to one liter of water at 43°C (110°F) | ||||
| – A solution of iodine (50 parts per million iodine). Make this in two steps: | ||||
| &sqbul; First, make a tincture of iodine by adding 6-8 grams of solid ammonium iodide and/or potassium iodide to 100 cc of 45% alcohol approximately | ||||
| &sqbul; Second, add 0.8 milliliters of the tincture to one liter of water at 43°C (110°F) to get the final solution | ||||
| – Other commercially available cleansers of equivalent disinfectant quality when used as directed, if their use is recommended or approved by the respirator manufacturer. | ||||
| 3. | Rinse components thoroughly in clean, warm (43°C (110°F) maximum), preferably, running water. | |||
| Note: The importance of thorough rinsing cannot be overemphasized. Detergents or disinfectants that dry on facepieces could cause dermatitis. In addition, some disinfectants may cause deterioration of rubber or corrosion of metal parts, if not completely removed. | ||||
| 4. | Drain components. | |||
| 5. | Air-dry components or hand dry components with a clean, lint-free cloth. | |||
| 6. | Reassemble the facepiece components. | |||
| • Replace filters, cartridges, and canisters, if necessary (for testing). | ||||
| 7. | Test the respirator to make sure all components work properly. | |||
[]
IMPORTANT:
• User seal checks are NOT a substitute for fit tests. See WAC 296-307-62010 for fit test procedures.
• You may use a seal check procedure recommended by the respirator manufacturer INSTEAD of the procedure outlined in Table 21 if you can demonstrate the procedure is based on a scientific study that, for example, demonstrates the procedure effectively identifies respirators that fit poorly when put on or adjusted.
You must:
• Make sure employees perform a user seal check as outlined in Table 21, EACH TIME the respirator is worn, to make sure the seal is adequate.
Table 21
| User Seal Check Procedure | ||
| Important information for employees: | ||
| • You need to conduct a seal check each time you put your respirator on BEFORE you enter the respirator use area. The purpose of a seal check is to make sure your respirator (which has been previously fit tested by your employer) is properly positioned on your face to prevent leakage during use and to detect functional problems | ||
| • The procedure below has two parts; a positive pressure check and a negative pressure check. You must complete both parts each time. It should only take a few seconds to perform, once you learn it | ||
| – If you cannot pass both parts, your respirator is NOT functioning properly, see your supervisor for further instruction. | ||
| Positive pressure check: | ||
| 1. Remove exhalation valve cover, if removable. | ||
| 2. Cover the exhalation valve completely with the palm of your hand WHILE exhaling gently to inflate the facepiece slightly. | ||
| 3. The respirator facepiece should remain inflated (indicating a build-up of positive pressure and NO outward leakage). | ||
| • If you detect NO leakage, replace the exhalation valve cover (if removed), and proceed to conduct the negative pressure check | ||
| • If you detect evidence of leakage, reposition the respirator (after removing and inspecting it), and try the positive pressure check again. | ||
| Negative pressure check: | ||
| 4. Completely cover the inhalation opening(s) on the cartridges or canister with the palm(s) of your hands WHILE inhaling gently to collapse the facepiece slightly. | ||
| • If you cannot use the palm(s) of your hands to effectively cover the inhalation openings on cartridges or canisters, you may use: | ||
| – Filter seal(s) (if available) | ||
| OR | ||
| – Thin rubber gloves. | ||
| 5. Once the facepiece is collapsed, hold your breath for 10 seconds WHILE keeping the inhalation openings covered. | ||
| 6. The facepiece should remain slightly collapsed (indicating negative pressure and NO inward leakage). | ||
| • If you detect NO evidence of leakage, the tightness of the facepiece is considered adequate, the procedure is completed, and you may now use the respirator | ||
| • If you detect leakage, reposition the respirator (after removing and inspecting it) and repeat BOTH the positive and negative fit checks. | ||

Scope.
This part applies only if your employees:
• Are exposed to a respiratory hazard
OR
• Could be exposed to one of the specific hazards listed below.
This part applies to any workplace with potential or actual employee exposure to respiratory hazards. It requires you to protect employees from respiratory hazards by applying this protection strategy:
• Evaluate employee exposures to determine if controls are needed
• Use feasible controls. For example, enclose or confine the operation, use ventilation systems, or substitute with less toxic material
• Use respirators if controls are not feasible or if they cannot completely remove the hazard.
Definition:
Exposed or exposure:
The contact an employee has with a toxic substance, harmful physical agent or oxygen deficient condition, whether or not protection is provided by respirators or other personal protective equipment (PPE). Exposure can occur through various routes of entry, such as inhalation, ingestion, skin contact, or skin absorption.
| Note: | Examples of substances that may be respiratory hazards when airborne include: |
| • Chemicals listed in Table 3 | |
| • Any substance | |
| – Listed in the latest edition of the NIOSH Registry of Toxic Effects of Chemical Substances | |
| – For which positive evidence of an acute or chronic health hazard exists through tests conducted by, or known to, the employer | |
| – That may pose a hazard to human health as stated on a material safety data sheet kept by, or known to, the employer | |
| • Atmospheres considered oxygen deficient | |
| • Biological agents such as harmful bacteria, viruses or fungi | |

Summary:
Your responsibility:
To protect your employees from exposure to respiratory hazards in the workplace by identifying and controlling the hazards.
You must:
Identify and evaluate employee exposures
Control employee exposures
Use respirators
Notify employees
Permissible exposure limits of air contaminants
[]
You must:
• Make sure employees are protected from potentially hazardous exposure while you perform your evaluation
• Perform your evaluation without considering the protection provided to employees by a respirator
• Determine the form of the hazard, such as dust, mist, gas, oxygen deficiency, or biological agent
• Make sure you consider:
– Potential emergency and rescue situations that may occur, such as equipment or power failures, uncontrolled chemical reactions, fire, explosion, or human error
– Workplace conditions such as work processes, types of material, control methods, work practices and environmental conditions.
• Determine or reasonably estimate whether any employee is or could be exposed to any of the following:
– Any airborne substance above a permissible exposure limit (PEL) listed in Table 3
– A substance at or above the action level (AL) specified in the rule for that substance
– Any other respiratory hazard.
• Use any of the following to determine employee exposure:
– Information that would allow an estimate of the level of employee exposure, such as MSDSs or pesticide labels, observations, measurements or calculations
– Data demonstrating that a particular product, material or activity cannot result in employee exposure at or above the AL or PEL
– Personal air samples that represent an employee's usual or worst case exposure for the entire shift.
| Note: | • Rules for specific substances may contain additional requirements for determining employee exposure. |
| • Use methods of sampling and analysis that have been validated by the laboratory performing the analysis. | |
| • Samples from a representative group of employees may be used for other employees performing the same work activities when the duration and level of exposure are similar. |
• Consider the atmosphere to be immediately dangerous to life or health (IDLH) when you cannot determine or reasonably estimate employee exposure
• Make sure employee exposure, to 2 or more substances with additive health effects, is evaluated using this formula:
| Em | = | C1 L1 |
+ | C2 L2 |
+ | ... | + | Cn Ln |
| The symbol | Is the . . . |
| E | Equivalent exposure for the mixture. When the value of E is greater than 1, a respiratory hazard is present. |
| C | Concentration of a particular substance. |
| L | TWA, STEL, or ceiling for that substance from Table 3. |
[]
You must:
• Use feasible controls to protect employees from exposure to respiratory hazards by:
– Reducing employee exposure to a level that removes the respiratory hazard, such as to a level below the permissible exposure limit (PEL) in Table 3;
OR
– Reducing the exposure to the lowest achievable level, when the respiratory hazard cannot be removed.
| Note: | The following table gives you examples of control methods. |
Table 1
Examples of Possible Controls
| Control: | For example: |
| Using a different chemical (substitution) | • Choose a chemical with a lower evaporation rate or vapor pressure. |
| • Choose a chemical without hazardous ingredients. | |
| Changing a process to lessen emissions | • Use hand rolling or paint dipping instead of paint spraying. |
| • Bolt items instead of welding them. | |
| Separating employees from emissions areas and sources | • Use control rooms. |
| • Build an enclosure around process machinery or other emissions sources. | |
| • Automate a process. | |
| Removing emissions at or near the source (local exhaust ventilation) | • Install exhaust hoods or slots to capture emissions. |
| • Use an exhausted enclosure (like a blasting cabinet or laboratory hood). | |
| Diluting and removing emissions in the work area (general exhaust ventilation) | • Allow natural air movement to create an adequate airflow through an area. |
| • Use mechanical fans. | |
| Modify work practices | • Change the position of the worker relative to the work so fumes, vapors, or smoke do not go into their face. |
| Rotate employees – Some specific rules prohibit the use of this control method |
• Move employees to another job that is without exposure, on a schedule to keep their total exposure below the permissible exposure limit. |
[]
You must:
• Require employees to use respiratory protection when respiratory hazards have not been removed using feasible controls. For example, use respirators at any of the following times:
– While controls are being evaluated or put in place
– When the respiratory hazard is not completely removed
– When controls are not feasible.
| Reference: | See WAC 296-307-594, Respirators, for respirator program requirements. |
[]
You must:
• Notify employees who are or may be exposed to respiratory hazards, as specified in Table 2.
| Note: | • The notification may be provided either individually, to a group, or by posting of results in an appropriate location that's accessible to affected employees. |
Table 2
Notification Requirements
| Notify employees of: | As follows: |
| Any exposure result above a permissible exposure limit (PEL) | Within five business days, after the employee's exposure result is known to the employer |
| The corrective action being taken to reduce employee exposure to or below the PEL | Within fifteen business days, after the employee's exposure result is known to the employer |
| AND | |
| The schedule for completion of the corrective action and any reasons why exposures cannot be lowered to below the PEL | |
| An exposure to these substances: | In writing, as specified in the rule specific to the substance |
| • Acrylonitrile | |
| • Arsenic (inorganic) | |
| • Asbestos | |
| • Benzene | |
| • Butadiene | |
| • Cadmium | |
| • Coke oven emissions | |
| • Cotton dust | |
| • 1,2-Dibromo-3-chloropropane | |
| • Ethylene oxide | |
| • Formaldehyde | |
| • Lead | |
| • Methylene chloride | |
| • Methylenedianiline | |
| • Vinyl chloride |

IMPORTANT:
The following information applies to Table 3, Permissible Exposure Limits for Air Contaminants.
• Exposure needs to be determined from personal air samples taken in the breathing zone or from monitoring representative of the employee's breathing zone.
• Ppm refers to parts of vapor or gas per million parts of air by volume, at 25 degrees C and 760 mm Hg pressure.
• Mg/m3 refers to milligrams of substance per cubic meter of air.
• For a metal that is measured as the metal itself, only the CAS number for the metal is given. The CAS numbers for individual compounds of the metal are not provided. For more information about CAS registry numbers see the website: http://www.cas.org.
• Time weighted averages (TWA8) represent the maximum allowed average exposure for any 8-hour time period. For work periods longer than 8 hours the TWA8 needs to be determined using the 8 continuous hours with the highest average concentration.
• Short-term exposure limits (STEL) represent maximum allowed average exposure for any fifteen-minute period, unless another time period is noted in Table 3.
• The ceiling represents the maximum allowed exposure for the shortest time period that can feasibly be measured.
• An "X" in the "skin" column indicates the substance can be absorbed through the skin, either by airborne or direct contact.
• Requirements for the use of gloves, coveralls, goggles, and other personal protective equipment can be found in WAC 296-307-100.
• The respirable fraction of particulate is measured by sampling with a size-selector having the following characteristics:
| Mean aerodynamic diameter in micrometers | Percent passing the selector |
| 1 | 97 |
| 2 | 91 |
| 3 | 74 |
| 4 | 50 |
| 5 | 30 |

Part Y-7
Hearing Loss Prevention (Noise)
NEW SECTION
WAC 296-307-630
Scope.
The purpose of this part is to:
• Prevent employee hearing loss by minimizing employee noise exposures
AND
• Make sure employees exposed to noise are protected.
These goals are accomplished by:
• Measuring and computing the employee noise exposure from all equipment and machinery in the workplace, as well as any other noise sources in the work area
• Protecting employees from noise exposure by using feasible noise controls
• Making sure employees use hearing protection, if you cannot feasibly control the noise
• Training employees about hearing loss prevention
• Evaluating your hearing loss prevention efforts by tracking employee hearing or periodically reviewing controls and protection
• Making appropriate corrections to your program.
| Reference: | Table 1 will help you determine the hearing loss prevention requirements for your workplace. For the specific requirements associated with Noise Evaluation Criteria, see WAC 296-307-63410 of this part. |
Table 1
Noise Evaluation Criteria
| Criteria | Description | Requirements |
| 85 dBA TWA8 | Full-day employee noise exposure dose. If you have one or more employees whose exposure equals or exceeds this level, you must have a hearing loss prevention program | – Hearing
protection – Training – Audiometric testing |
| 90 dBA TWA8 | Full-day employee noise exposure dose. If you have one or more employees whose exposure equals or exceeds this level, you must reduce employee noise exposures in the workplace | – Noise controls AND – Hearing protection – Training – Audiometric testing |
| 115 dBA measured using slow response | Extreme noise level (greater than one second in duration) | – Hearing
protection – Signs posted in work areas warning of exposure |
| 140 dBC measured using fast response | Extreme impulse or impact noise (less than one second in duration) | Hearing protection |
[]
HEARING LOSS PREVENTION PROGRAMYour responsibility:
To prevent employee hearing loss by minimizing, and providing protection from, noise exposures.
You must:
Conduct employee noise exposure monitoring
Control employee noise exposures that equal or exceed 90 dBA TWA8
Make sure employees use hearing protection when their noise exposure equals or exceed 85 dBA TWA8
Make sure exposed employees receive training about noise and hearing protection
Make sure warning signs are posted for areas with noise levels that equal or exceed 115 dBA
Arrange for oversight of audiometric testing
Identify and correct deficiencies in your hearing loss prevention program
Document your hearing loss prevention activities
[]
You must:
• Conduct employee noise exposure monitoring to determine the employee's actual exposure when reasonable information indicates that any employee's exposure may equal or exceed 85 dBA TWA8.
| Note: | • Representative monitoring may be used where several employees perform the same tasks in substantially similar conditions |
| • Examples of information or situations that can indicate exposures which equal or exceed 85 dBA TWA8, include: | |
| – Noise in the workplace that interferes with people speaking, even at close range | |
| – Information from the manufacturer of equipment you use in the workplace that indicates high noise levels for machines in use | |
| – Reports from employees of ringing in their ears or temporary hearing loss | |
| – Warning signals or alarms that are difficult to hear | |
| – Work near abrasive blasting or jack hammering operations | |
| – Use of tools and equipment such as the following: | |
| &sqbul; Heavy equipment or machinery | |
| &sqbul; Fuel-powered hand tools | |
| &sqbul; Compressed air-driven tools or equipment in frequent use | |
| &sqbul; Power saws, grinders or chippers | |
| &sqbul; Powder-actuated tools. |
• Follow applicable guidance in WAC 296-307-634 when conducting noise exposure monitoring
• Make sure your sampling for noise exposure monitoring identifies:
– All employees whose exposure equals or exceeds the following:
&sqbul; 85 dBA TWA8 (noise dosimetry, providing an average exposure over an eight-hour time period)
&sqbul; 115 dBA (slow response sound level meter, identifying short-term noise exposures)
&sqbul; 140 dBC (fast response sound level meter, identifying almost instantaneous noise exposures).
– Exposure levels for selection of hearing protection.
• Provide exposed employees and their representatives with an opportunity to observe any measurements of employee noise exposure that are conducted
• Notify each employee whose exposure equals or exceeds 85 dBA TWA8 of the monitoring results within five working days of when you receive the results
• Conduct additional noise monitoring whenever a change in production, process, equipment or controls, may reasonably be expected to result in:
– Additional employees whose exposure equals or exceeds 85 dBA TWA8
– Employees exposed to higher level of noise requiring more effective hearing protection.
| Note: | Conditions that may be expected to increase exposure include: |
| • Adding machinery to the work area | |
| • Increasing production rates | |
| • Removal or deterioration of noise control devices | |
| • Increased use of noisy equipment | |
| • Change in work schedule | |
| • Change of job duties. |
[]
IMPORTANT:
Hearing protection provides a barrier to noise and protects employees but is not considered a control of the noise hazard. Separate requirements apply to hearing protection and are found in WAC 296-307-63215.
You must:
• Reduce employee noise exposure, using feasible controls, wherever exposure equals or exceeds 90 dBA TWA8.
| Note: | • Once noise exposures are brought below 90 dBA TWA8, no further reduction is required. However, further reduction of noise may reduce the need for other hearing loss prevention requirements |
| • Controls that eliminate noise at the source or establish a permanent barrier to noise are typically more reliable. For example: | |
| – Replacing noisy equipment with quiet equipment | |
| – Using silencers and mufflers | |
| – Installing enclosures | |
| – Damping noisy equipment and parts. | |
| • Other controls and work practices may also be useful for reducing noise exposures. Examples include: | |
| – Employee rotation | |
| – Limiting use of noisy equipment | |
| – Rescheduling work. |
[]
You must:
• Make sure employees wear hearing protectors that will provide sufficient protection when exposure equals or exceeds:
– 85 dBA TWA8 (noise dosimetry, providing an average exposure over an eight-hour time period)
– 115 dBA (slow response sound level meter, identifying short-term noise exposures)
– 140 dBC (fast response sound level meter, identifying almost instantaneous noise exposures).
• Provide employees with an appropriate selection of hearing protectors:
– The selection must include at least two distinct types (such as molded earplugs, foam earplugs, custom-molded earplugs, earcaps, or earmuffs) for each exposed employee and must be sufficient to cover:
&sqbul; Different levels of hearing protection needed in order to reduce all employee exposures to a level below 85 dBA TWA8 &sqbul; Different sizes
&sqbul; Different working conditions.
– Consider requests of the employees regarding:
&sqbul; Physical comfort
&sqbul; Environmental conditions
&sqbul; Medical needs
&sqbul; Communication requirements.
| Note: | Hearing protector selection should include earplugs, earcaps and earmuffs. |
• Provide hearing protection at no cost to employees
• Supervise employees to make sure that hearing protection is used correctly
• Make sure hearing protectors are:
– Properly chosen for fit
– Replaced as necessary.
• Make sure all hearing protection is sufficient to reduce the employee's equivalent eight-hour noise exposure to 85 dBA or less. When using the A-weighted exposure measurements, reported as "dBA TWA8," the reduction in noise exposure by hearing protectors is given by Table 2:
Table 2
Effective Protection of Hearing Protectors
| Type of hearing protection | Effective protection |
| Single hearing protection (earplugs, earcaps or earmuffs) | 7 dB less than the manufacturer assigned noise reduction rating (NRR); for example, earplugs with an NRR of 20 dB are considered to reduce employee exposures of 95 dBA TWA8 to 82 dBA TWA8 |
| Dual hearing protection (earplug and earmuff worn together) | 2 dB less than the higher NRR of the two protectors; for example, earplugs with an NRR of 20 dB and earmuffs with an NRR of 12 dB are considered to reduce employee exposures of 100 dBA TWA8 to 82 dBA TWA8 |
| Note: | You may also evaluate hearing protection by using the other methods given in the NIOSH Compendium of Hearing Protection (DHHS (NIOSH)) Publication No. 95-105 or online at http://www.cdc.gov/niosh/topics/noise/hpcomp.html. These methods require additional monitoring and are more complex, but provide a more thorough evaluation of protection. This may be useful in cases where communication is critical or for evaluating hearing protection for employees with hearing impairment. |
[]
You must:
• Train all employees whose noise exposure equals or exceeds 85 dBA TWA8 • Provide training when an employee is first assigned to a position involving noise exposure that equals or exceeds 85 dBA TWA8 and at least annually after that
• Update information provided in the training program to be consistent with changes in controls, hearing protectors and work processes
• Make sure your noise and hearing protection training includes:
– The effects of noise on hearing (including both occupational and nonoccupational exposures)
– Noise controls used in your workplace
– The purpose of hearing protectors: The advantages, disadvantages, and attenuation of various types
– Instructions about selecting, fitting, using, and caring for hearing protection
– The purpose and procedures for program evaluation including audiometric testing and hearing protection auditing when you choose to rely upon auditing (see WAC 296-307-638)
– The employees' right to access records kept by the employer.
• Maintain a written program describing initial and refresher training.
[]
You must:
• Make sure warning signs are posted at the entrances or boundaries of all well-defined work areas where employees may be exposed to noise that equals or exceeds 115 dBA (measured using a sound level meter with slow response).
– Warning signs must clearly indicate that the area is a high noise area and that hearing protectors are required.
[]
You must:
• Make sure audiometric testing as described by WAC 296-307-636 is supervised and reviewed by one of the following licensed or certified individuals:
– An audiologist
– An otolaryngologist
– Another qualified physician.
• Make sure audiograms are conducted by one of the above individuals or by a technician certified by the Council of Accreditation in Occupational Hearing Conservation (CAOHC) and responsible to a qualified reviewer.
[]
You must:
• Use audiometric testing to identify hearing loss, which may indicate program deficiencies
• Take appropriate actions when deficiencies are found with your program.
– A deficiency may be indicated when:
&sqbul; Any employee experiences measurable hearing loss indicated by a standard threshold shift
OR
&sqbul; Any employee isn't wearing appropriate hearing protection during an audit when auditing is used in place of baseline audiograms for short term employees (see WAC 296-307-638, Option to audiometric testing).
| Note: | A standard threshold shift or audit deficiency does not necessarily indicate that a significant hearing loss has occurred. These criteria are intended to help identify where there may be flaws in your hearing loss prevention program that can be fixed before permanent hearing loss occurs. |
| There are additional statistical tools and tests that may be used to improve the effectiveness of your program. Staff conducting audiometric testing and auditing may be able to suggest additional ways to improve your hearing loss prevention program and tailor it to your worksite. |
• Evaluate the following, at a minimum, when responding to a standard threshold shift:
– Employee noise exposure measurements
– Noise controls in the work area
– The selection of hearing protection available and refit employees as necessary
– Employee training on noise and the use of hearing protection and conduct additional training as necessary.
| Reference: | You may use the option of auditing hearing protection (see WAC 296-307-638) for employees hired or transferred to jobs with noise exposure for less than one year. You may also use audiograms provided by a third-party hearing loss prevention program in some circumstances. Details of these program options are found in WAC 296-307-638, Options to audiometric testing. |
[]
You must:
• Create and retain records documenting noise exposures. Include, at a minimum:
– Exposure measurements required by this part for at least two years and for as long as you rely upon them to determine employee exposure
– Audiometric test records for the duration of employment for the affected employees
– Hearing protection audits, if you choose to rely upon them, for the duration of employment of the affected employees.
| Note: | • You need to keep as complete a record as possible. Records developed under previous rules or in other jurisdictions need to be kept, even when they do not fulfill the full requirements of this part. Similarly, records found to have errors in collection or processing need to be kept if they provide an indication of employee exposure or medical condition not found in other records |
| • You may want to consider your other business needs, such as worker's compensation claims management, before discarding these records. |
[]
NOISE MEASUREMENT AND COMPUTATIONYour responsibility:
Conduct noise monitoring or measurement to evaluate employee exposures in your workplace.
You must:
Make sure that noise-measuring equipment meets recognized standards
Measure employee noise exposure
Use these equations when estimating full-day noise exposure from sound level measurements
[]
You must:
• Make sure that noise dosimetry equipment meets these specifications:
– Dosimeters must be equipment class 2AS-90/80-5 of the American National Rule Specification for Personal Noise Dosimeters, ANSI S1.25-1991, such dosimeters are normally marked "Type 2."
| Note: | Make sure any dosimeter you use is Type 2 equipment that: |
| • Uses slow integration and A-weighting of sound levels. | |
| • Has the criterion level set to 90 dB, so the dosimeter will report a constant 8-hour exposure at 90 dBA as a 100% dose. | |
| • Has the threshold level set at 80 dB, so the dosimeter will register all noise above 80 dB. | |
| • Uses a 5 dB exchange rate for averaging of noise levels over the sample period. |
• Make sure that sound level meters meet these specifications:
– American National Standard Specification for Sound Level Meters, S1.4-1984, Type 2 requirements for sound level meters, such sound level meters are normally marked "Type 2."
&sqbul; For continuous noise measurements, the meter must be capable of measuring A-weighted sound levels with slow response
&sqbul; For impulse or impact noise measurements, the meter must be capable of indicating maximum C-weighted sound level measurements with fast response.
• Calibrate dosimeters and sound level meters used to monitor employee noise exposure:
– Before and after each day's use
AND
– Following the instrument manufacturer's calibration instructions.
| Note: | • You may conduct dosimetry using an exchange rate less than 5 dB and compare the results directly to the noise evaluation criteria in Table 1 |
| • For measuring impulse and impact noise you may also use a sound level meter set to measure maximum impulse C-weighted sound levels or peak C-weighted sound levels. |
[]
IMPORTANT:
A noise dosimeter is the basis for determining total daily noise exposure for employees. However, where you have constant noise levels, you may estimate employee noise exposure using measurements from a sound level meter. Calculation of the employee noise exposure must be consistent with WAC 296-307-63415.
You must:
• Include all:
– Workplace noise from equipment and machinery in use
– Other noise from sources necessary to perform the work
– Noise outside the control of the exposed employees.
• Use a noise dosimeter when necessary to measure employee noise dose
• Use a sound level meter to evaluate continuous and impulse noise levels
• Identify all employees whose exposures equal or exceed the Noise Evaluation Criteria as follows:
Noise Evaluation Criteria
| Criteria | Description | Requirements |
| 85 dBA TWA8 | Full-day employee noise exposure dose. If you have one or more employees whose exposure equals or exceeds this level, you must have a hearing loss prevention program | – Hearing
protection – Training – Audiometric testing |
| 90 dBA TWA8 | Full-day employee noise exposure dose. If you have one or more employees whose exposure equals or exceeds this level, you must reduce employee noise exposures in the workplace | Noise controls (in addition to the requirements for 85 dBA TWA8) |
| 115 dBA measured using slow response | Extreme noise level (greater than one second in duration) | – Hearing
protection – Signs posted in work areas warning of exposure |
| 140 dBC measured using fast response | Extreme impulse or impact noise (less than one second in duration) | Hearing protection |
[]
You must:
• Compute employee's full-day noise exposure by using the appropriate equations from Table 3 "Noise Dose Computation" when using a sound level meter to estimate noise dose.
Table 3
Noise Dose Computation
| Description | Equation |
| Compute the noise dose based on several time periods of constant noise during the shift | The total noise dose over the
work day, as a percentage, is
given by the following equation
where Cn indicates the total time
of exposure at a specific noise
level, and Tn indicates the
reference duration for that level. D = 100*((C1/T1) + (C2/T2) + (C3/T3) + ... + (Cn/Tn)) |
| The reference duration is equal to the time of exposure to continuous noise at a specific sound level that will result in a one hundred percent dose | The reference duration, T, for
sound level, L, is given in hours
by the equation: T = 8/(2^((L - 90)/5)) |
| Given a noise dose as a percentage, compute the equivalent eight-hour time weighted average noise level | The equivalent eight-hour time
weighted average, TWA8, is
computed from the dose, D, by
the equation: TWA8 = 16.61* Log10(D/100) + 90 |
[]
AUDIOMETRIC TESTINGYour responsibility:
To conduct audiometric testing of employees exposed to noise to make sure that their hearing protection is effective.
You must:
Provide audiometric testing at no cost to employees
Establish a baseline audiogram for each exposed employee
Conduct annual audiograms
Review audiograms that indicate a standard threshold shift
Keep the baseline audiogram without revision, unless annual audiograms indicate a persistent threshold shift or a significant improvement in hearing
Make sure a record is kept of audiometric tests
Make sure audiometric testing equipment meets these requirements
[]
You must:
• Provide audiograms, including any required travel or necessary additional examinations or testing, at no cost to exposed employees.
[]
You must:
• Conduct a baseline audiogram when an employee is first assigned to work involving noise exposures that equal or exceed 85 dBA TWA8.
– Make sure this audiogram is completed no more than one hundred eighty days after the employee is first assigned
OR
– Make sure employee is covered by a hearing protection audit program (as described by WAC 296-307-638 and available as an alternative only for employees hired for less than one year).
| Note: | Employers who utilize mobile test units are allowed up to one year to obtain a valid baseline audiogram for each exposed employee. The employees must still be given training and hearing protection as required by this part. |
• Make sure employees are not exposed to workplace noise at least fourteen hours before testing to establish a baseline audiogram.
– Hearing protectors may be used to accomplish this.
• Notify employees of the need to avoid high levels of nonoccupational noise exposure (such as loud music, headphones, guns, power tools, motorcycles, etc.) during the fourteen-hour period immediately preceding the baseline audiometric examination.
[]
You must:
• Conduct annual audiograms for employees as long as they continue to be exposed to noise that equals or exceeds 85 dBA TWA8.
| Note: | Annual audiometric testing may be conducted at any time during the work shift. By conducting the annual audiogram during the work shift with the employee exposed to typical noise for their job, the test may record a temporary threshold shift. This makes the test more sensitive to potential hearing loss and may help you improve employee protection before a permanent threshold shift occurs. A suspected temporary shift is one reason an employer may choose to retest employee hearing. |
• Make sure each employee is informed of the results of his or her audiometric test.
– Include whether or not there has been a hearing level decrease or improvement since their previous test.
• Make sure each employee's annual audiogram is compared to his or her baseline audiogram by an audiologist, otolaryngologist, another qualified physician, or the technician conducting the test to determine if a standard threshold shift has occurred.
– If the annual audiogram indicates that an employee has suffered a standard threshold shift, you may obtain a retest within thirty days and consider the results of the retest as the annual audiogram.
• Make sure that an audiologist, otolaryngologist, or other qualified physician sees any annual audiogram that indicates a standard threshold shift.
[]
You must:
• Make sure the healthcare professional supervising audiograms has:
– A copy of this part
– The baseline audiogram and most recent audiogram of the employee to be evaluated
– Background noise level records for the testing room
– Calibration records for the audiometer.
• Obtain an opinion from the healthcare professional supervising audiograms as to whether the audiograms indicate possible occupational hearing loss and any recommendations for changes in hearing protection.
• Pay for any clinical audiological evaluation or otological examination required by the reviewer, if:
– Additional review is necessary to evaluate the cause of hearing loss
OR
– If there is indication of a medical condition of the ear caused or aggravated by the wearing of hearing protectors.
• Inform the employee in writing of the existence of a standard threshold shift within twenty-one calendar days of the determination.
• Make arrangements for the reviewer to communicate to the employee any suspected medical conditions that are found unrelated to your workplace. This information is confidential and must be handled appropriately.
[]
You must:
• Keep the baseline audiogram without revision, unless a qualified reviewer determines:
– The standard threshold shift revealed by the audiogram is persistent
OR
– The hearing threshold shown in the annual audiogram indicates significant improvement over the baseline audiogram.
[]
You must:
• Retain a legible copy of all employee audiograms conducted under this part.
– Make sure the record includes:
&sqbul; Name and job classification of the employee
&sqbul; Date of the audiogram
&sqbul; The examiner's name
&sqbul; Date of the last acoustic or exhaustive calibration of the audiometer
&sqbul; Employee's most recent noise exposure assessment
&sqbul; The background sound pressure levels in audiometric test rooms.
[]
You must:
• Use pure tone, air conduction, hearing threshold examinations, with test frequencies including as a minimum 500, 1000, 2000, 3000, 4000, and 6000 Hz
– Tests at each frequency must be taken separately for each ear
– Supra-aural headphones must be used.
• Conduct audiometric tests with audiometers (including microprocessor audiometers) that meet the specifications of, and are maintained and used according to, American National Standard Specification for Audiometers, S3.6-1996
• Check the functional operation of the audiometer each day before use by doing all of the following:
– Make sure the audiometer's output is free from distorted or unwanted sound
– Test either a person with known, stable hearing thresholds or a bio-acoustic simulator
– Perform acoustic calibration for deviations of 10 dB or greater.
• Audiometer calibration must be checked acoustically at least annually to verify continued conformance with ANSI S3.6-1996. Test frequencies below 500 Hz and above 6000 Hz may be omitted from this check
• An exhaustive calibration must be performed at least every two years according to the American National Standard Specification for Audiometers, S3.6-1996. Test frequencies below 500 Hz and above 6000 Hz may be omitted from the calibration
• Provide audiometric test rooms that meet the requirements of ANSI S3.1-1999 American National Standard Maximum Permissible Ambient Noise Levels for Audiometric Test Rooms using the following table of Maximum Ambient Sound Pressure Levels:
| Frequency (Hz) | 500 | 1000 | 2000 | 4000 | 8000 |
| Sound Pressure Level (dB) | 40 | 40 | 47 | 57 | 62 |
| Note: | The American Industrial Hygiene Association and National Hearing Conservation Association recommend conducting audiograms using the requirements of ANSI S3.1-1999 American National Standard Maximum Permissible Ambient Noise Levels for Audiometric Test Rooms with adjustments at only 500 Hz and below. |
[]
OPTIONS TO AUDIOMETRIC TESTINGYour responsibility:
This section provides options to baseline audiometric testing for employees assigned to duties with noise exposures for less than one year. These program options may also be used to provide added assessment of longer-term employees in addition to audiometric testing.
The requirements of this section apply only if you decide to use auditing or a third-party hearing loss prevention program and do not conduct baseline audiometric testing for those employees.
Hearing Protection Audits
You must:
Conduct hearing protection audits at least quarterly
Make sure staff conducting audits are properly trained
Assess the hearing protection used by each employee during audits
Document your hearing protection audits
Third-Party Audiometric Testing
You must:
Make sure third-party hearing loss prevention programs meet the following requirements
IMPORTANT:
Hearing protection audits are a tool for use in evaluating your hearing loss prevention program in cases where audiometric testing does not provide a useful measure. For example, if most of your employees are hired on a temporary basis for a few months at a time, audiometric testing may not identify the small changes in hearing acuity that could occur. Auditing provides an alternative to audiometric testing in these cases.
Auditing is not required unless you use it in place of baseline audiometric testing for employees hired for a period of less than one year and is permitted as a substitute for audiometric testing only for these employees.
Third-party hearing loss prevention programs are full hearing loss prevention programs and are distinct from audiometric testing provided by third parties as part of your own hearing loss prevention program. These programs may be organized by labor groups, trade associations, labor-management cooperatives, or other organizations to:
• Cover a specific group of employees
OR
• Combine efforts for several employers with common employees.
Although you remain responsible for the program, third-party programs can have at least two benefits over running your own program:
• The audiometric testing is portable between the participating employers so new testing will not be needed when an employee changes employers
• Employees who only work for short periods for any one employer can be monitored under the group program over a longer period of time increasing the effectiveness of the audiometric testing in preventing hearing loss for these employees.
[]
You must:
• Conduct audits at least quarterly to provide a representative assessment of your workplace
– The assessment is representative if it:
&sqbul; Covers all processes and work activities in your business at full production levels
AND
&sqbul; Covers all employees present on the audit day.
– If your business is mobile or involves variable processes, auditing may need to be repeated more often than quarterly
– Auditing does not need to be repeated more than monthly as long as a reasonable effort is made to cover:
&sqbul; The activities with greatest exposure
AND
&sqbul; As many employees as possible.
• Assess exposures and hearing protection for the full shift for each employee covered at the time of the audit.
[]
You must:
• Make sure staff conducting hearing protection audits:
– Can demonstrate competence in:
&sqbul; Evaluating hearing protection attenuation
&sqbul; Evaluating hearing protector choices
&sqbul; Assessing the correct use of hearing protectors.
– Are certified by the Council for Accreditation in Occupational Hearing Conservation (CAOHC) or have training in the following areas:
&sqbul; Noise and hearing loss prevention
&sqbul; Washington state noise regulations
&sqbul; Hearing protectors
&sqbul; Fitting of hearing protectors
&sqbul; Basic noise measurement
&sqbul; Hearing loss prevention recordkeeping.
[]
You must:
• Confirm that:
– Current site conditions during audits are consistent with conditions existing during noise monitoring
– The hearing protection used by the employee is sufficient and appropriate for the conditions
– The hearing protection is worn properly
– The employees are satisfied with the performance and comfort of the hearing protection.
[]
You must:
• Keep a record of audit results for each employee assessed for the length of their employment and for the length of time you will rely upon the audit results
• Include the following information in the record:
– The make and model of the hearing protectors
– The size of the protectors
– Average noise exposure of the employee
– Any problems found with use of the hearing protection
– Any comments or complaints from the employee regarding the hearing protection.
[]
THIRD-PARTY AUDIOMETRIC TESTSIMPORTANT:
Third-party hearing loss prevention programs are intended:
• For short-term employees hired or assigned to duties having noise exposures for less than one year
AND
• For seasonal employees.
However, other employees may be included as long as you meet all requirements for hearing loss follow-ups and recordkeeping.
You must:
• Make sure that the third-party program is:
– Equivalent to an employer program as required by this part
AND
– Uses audiometric testing to evaluate hearing loss.
• Make sure a licensed or certified audiologist, otolaryngologist, or other qualified physician administers the third-party program
• Make sure the third-party program has written procedures for:
– Communicating with participating employers of program requirements
– Follow-up procedures for detected hearing loss
– Annual review of participating employer programs.
• Make sure the following program elements are corrected by you or the third-party program when deficiencies are found:
– Noise exposures
– Hearing protection
– Employee training
– Noise controls.
• Obtain a review of your hearing loss prevention program at least once per year, conducted by the third-party program administrator or their representative, in order to:
– Identify any tasks needing a revised selection of hearing protection
AND
– Provide an overall assessment of the employers' hearing loss prevention activities.

A-weighted - An adjustment to sound level measurements that reflects the sensitivity of the human ear. Used for evaluating continuous or average noise levels.
Audiogram - A chart, graph, or table resulting from an audiometric test showing an individual's hearing threshold levels as a function of frequency.
Audiologist - A professional, specializing in the study and rehabilitation of hearing, who is certified by the American Speech, Hearing, and Language Association, or the American Academy of Audiology, and is licensed by the state board of examiners.
Baseline audiogram - The audiogram against which future audiograms are compared. The baseline audiogram is collected when an employee is first assigned to work with noise exposure. The baseline audiogram may be revised if persistent standard threshold shift (STS) of improvement is found.
Continuous noise - Noise with peaks spaced no more than one second apart. Continuous noise is measured using sound level meters and noise dosimeters with the slow response setting.
Criterion sound level - A sound level of ninety decibels. An eight-hour exposure to constant 90 dBA noise is a one hundred percent noise dose exposure.
C-weighted - An adjustment to sound level measurements that evenly represents frequencies within the range of human hearing. Used for evaluating impact or impulse noise.
Decibel (dB) - Unit of measurement of sound level. A-weighting, adjusting for the sensitivity of the human ear, is indicated as "dBA." C-weighting, an even reading across the frequencies of human hearing, is indicated as "dBC."
Fast response - A setting for a sound level meter that will allow the meter to respond to noise events of less than one second. Used for evaluating impulse and impact noise levels.
Hertz (Hz) - Unit of measurement of frequency, numerically equal to cycles per second.
Impulsive or impact noise - Noise levels which involve maxima at intervals greater than one second. Impulse and impact noise are measured using the fast response setting on a sound level meter.
Noise dose - The total noise exposure received by an employee during their shift. It can be expressed as a percentage indicating the ratio of exposure received to the noise exposure received in an eight-hour exposure to constant noise at 90 dBA. It may also be expressed as the sound level that would produce the equivalent exposure during an eight-hour period (TWA8).
Noise dosimeter - An instrument that integrates a function of sound pressure over a period of time in such a manner that it directly indicates a noise dose.
Occupational hearing loss - A reduction in the ability of an individual to hear either caused or contributed to by exposure in the work environment.
Otolaryngologist - A physician specializing in diagnosis and treatment of disorders of the ear, nose and throat.
Permanent threshold shift - A hearing level change that has become persistent and is not expected to improve.
Qualified reviewer - An audiologist, otolaryngologist, or other qualified physician who has experience and training in evaluating occupational audiograms.
Slow response - A setting for sound level meters and dosimeters in which the meter does not register events of less than about one second. Used for evaluating continuous and average noise levels.
Sound level - The intensity of noise as indicated by a sound level meter.
Sound level meter - An instrument that measures sound levels.
Standard threshold shift (STS) - A hearing level change, relative to the baseline audiogram, of an average of 10 dB or more at 2000, 3000, and 4000 Hz in either ear.
Temporary threshold shift - A hearing level change that improves. A temporary threshold shift may occur with exposure to noise and hearing will return to normal within a few days. Temporary threshold shifts can be indicators of exposures that lead to permanent hearing loss.
TWA8 - Equivalent eight-hour time-weighted average sound level - That sound level, which if constant over an eight-hour period, would result in the same noise dose measured in an environment where the noise level varies.

• Has limited or restricted entry or exit. Examples of spaces with limited or restricted entry are tanks, vessels, silos, storage bins, hoppers, vaults, excavations, and pits.
• Not primarily designed for human occupancy.
| Note: | • Requirements in other chapters may apply to your work. You will find some safety and health requirements are addressed on a broad level in this part, while being addressed for a specific application in another rule. When this happens, both requirements apply and should not conflict. When a conflict does occur, you need to follow the more specific requirement. |
| • If you are uncertain which requirements to follow, contact your local labor and industries (L&I) office. |
[]
Your responsibility:
To identify your permit-required confined spaces and control employee entry.
You must:
Identify permit-required confined spaces.
Inform employees and control entry to permit-required confined spaces.
Follow these requirements when you contract with another employer to enter your confined space.
[]
IMPORTANT:
If your workplace contains only nonpermit confined spaces and your employees do not enter another employer's confined space, you may follow only the requirements in:
– WAC 296-307-644, Identifying and controlling permit-required confined spaces; and
– WAC 296-307-654, Nonpermit confined space requirements.
You must:
• Identify all permit-required confined spaces in your workplace.
• Assume any confined space is a permit-required confined space, unless you determine the space to be a nonpermit confined space.
– If you enter the space to determine the hazards, follow the requirements in WAC 296-307-650, Permit entry procedures.
– If you evaluate the confined space and there are no potential or actual hazards, you can consider it to be a nonpermit confined space.
• Document your determination that the space is nonpermit, as required by WAC 296-307-654.
Definitions:
A permit-required confined space or permit space is a confined space that has one or more of the following characteristics capable of causing death or serious physical harm:
– Contains or has a potential to contain a hazardous atmosphere.
– Contains a material with the potential for engulfing someone who enters the space.
– Has an internal configuration that could allow someone entering to be trapped or asphyxiated by inwardly converging walls or by a floor, which slopes downward and tapers to a smaller cross-section.
– Contains any physical hazard. This includes any recognized health or safety hazards including engulfment in solid or liquid material, electrical shock, or moving parts.
– Contains any other recognized safety or health hazard that could either:
• Impair the ability to self rescue;
OR
• Result in a situation that presents an immediate danger to life or health.
A nonpermit confined space is a confined space that does NOT contain actual hazards or potential hazards capable of causing death or serious physical harm.
[]
You must:

– Using any other equally effective means to inform employees.
| Note: | A sign reading "Danger-Permit Required Confined Space, DO NOT ENTER" or using pictures or other similar wording employees can understand would satisfy the requirement for a sign. |
(2) Take effective measures to prevent unauthorized employees from entering permit-required confined spaces.
| Note: | Examples of measures to prevent employee entry include padlocks, bolted covers, special tools to remove covers, and providing employee training. |
[]
IMPORTANT:
The contractor is responsible for following all confined space requirements in this part and in other rules that apply.
You must:
• Do all of the following if you arrange to have another employer (contractor) perform work that involves entry into your permit-required confined space:
– Inform the contractor:
&sqbul; That the workplace contains permit-required confined spaces and entry is allowed only if the applicable requirements of this part are met.
&sqbul; Of the identified hazards and your experience with each permit-required confined space.
&sqbul; Of any precautions or procedures you require for the protection of employees in or near spaces where the contractor will be working.
– Coordinate entry operations with the contractor, when either employees or employers from the different companies will be working in or near permit-required confined spaces.
– Discuss entry operations with the contractor when they are complete. Include the following in your discussion:

| – Any other method that is effective for the employer. |
• Provide training at the following times:
– Before an employee is first assigned to duties covered by this part.
– Before there is a change in an employee's assigned duties.
– When there is a permit-required confined space hazard for which the employee has not already been trained.
– If you have reason to believe that there are either:
&sqbul; Deviations from your procedures for permit-required confined space entry; or
&sqbul; Employee knowledge or use of your procedures is inadequate.
[]
You must:
• Certify employee proficiency in their assigned duties.
• Make sure the certification:
– Contains each employee's name, the trainer's written or electronic signature or initials, and the dates of training.
– Is available for inspection by employees and their authorized representatives.
[]

[]
You must:
• Keep entry permits for at least one year.
• Keep entry permits or other atmospheric monitoring records that show the actual atmosphere an employee entered or worked in, as employee exposure records.
• Review your permit-required confined space entry program as follows:
– Conduct a review when you have any reason to believe your entry program may not protect employees, and revise your program before allowing subsequent entries.
| Note: | Examples of circumstances requiring the review of your program include the following: |
| • There is unauthorized entry of a permit space. | |
| • A permit space hazard not covered by the permit is found. | |
| • A condition prohibited by the permit occurs. | |
| • An injury or near-miss occurs during entry. | |
| • There is a change in the use or configuration of a permit space. | |
| • An employee complains about the effectiveness of the program. |
• Review canceled entry permits within one year following each entry to evaluate:
– Your permit-required confined space program.
– The protection provided to employees entering permit-required confined spaces.
• Update your written permit-required confined space entry program as necessary.
| Note: | Employers may perform a single annual review covering all entries performed during a twelve-month period. If no entry is performed during a twelve-month period, no review is necessary. |
[]
You must:
• Implement measures necessary to prevent unauthorized entry into permit-required confined spaces, when conducting authorized entry.
| Note: | • When removing entrance covers to open the confined space, protect entrants and those outside the confined space from hazards. |
| • Examples of measures to prevent unauthorized entry are signs, barricades, warning tape, and an attendant. |
[]
You must:
• Provide the equipment in Table 2, when needed and at no cost to employees.
• Make sure that employees use provided equipment properly.
• Maintain the provided equipment.
| Type of equipment | For |
| Testing and monitoring equipment | Evaluating permit-required confined space conditions |

| Lighting equipment | Employees to see well enough to work safely and to exit the space quickly in an emergency |
| Barriers or shields, such as pedestrian, vehicle or other barriers | Protecting employees from hazards outside of the space |
| Ladders | Safe entry and exit by entrants |
| Rescue and emergency equipment, except for equipment provided by the rescue service provider | Safe and effective rescue |
| Any other equipment | Safe entry into and rescue from permit-required confined spaces |
[]
• Evaluate and control hazards for safe entry into permit-required confined spaces by doing all the following:
– Test for atmospheric hazards, in this order:
&sqbul; Oxygen.
&sqbul; Combustible gases and vapors.
&sqbul; Toxic gases and vapors.
– Provide each entrant or their authorized representative an opportunity to observe any of the following:
&sqbul; Preentry testing.
&sqbul; Subsequent testing.
&sqbul; Monitoring of permit-required spaces.
– Reevaluate the permit-required space in the presence of any entrant, or their authorized representative, who requests this to be done because they have reason to believe that the evaluation of that space may not have been adequate.
– Upon request, immediately provide each entrant or their authorized representative, with the results of any testing required by this rule.
– Continuously monitor conditions in areas where entrants are working, when isolation of the space is not feasible.
• Examples would be a large space or space that is part of a continuous system, such as a sewer.
• Evaluate space conditions during entry as follows:
| You must: | In order to |
| Test conditions before entry | Determine that acceptable entry conditions exist before entry is authorized by the entry supervisor |
| Test or evaluate space conditions during entry | Determine that acceptable entry conditions are being maintained during entry operations |
| Evaluate entry operations | Make sure entrants of more than one employer working at the same time in or around a permit-required confined space, do not endanger each other |
This section applies to both:
• Employers whose employees use permit entry procedures; and
• Employers who provide rescue services.
[]
You must:
(1) Make sure you have adequate rescue and emergency services available during your permit-required confined space entry operations.
• Evaluate and select rescue teams or services who can:
– Respond to a rescue call in a timely manner. Timeliness is based on the identified hazards. Rescuers must have the capability to reach potential victims within an appropriate time frame based on the identified permit space hazards.
– Proficiently rescue employees from a permit-required confined space in your workplace. Rescuers must have the appropriate equipment for the type of rescue.
• Make sure that at least one member of the rescue team or service holds a current certification in first aid and cardiopulmonary resuscitation (CPR).
• Inform each rescue team or service about the hazards they may confront when called to perform rescue.
• Provide the rescue team or service with access to all permit spaces from which rescue may be necessary.
– This will allow them to develop appropriate rescue plans and to practice rescue operations.
| Note: | What will be considered timely will vary according to the specific hazards involved in each entry. For example, WAC 296-307-594, Respirators, requires that employers provide a standby person or persons capable of immediate action to rescue employee(s) for work areas considered to contain an IDLH atmosphere. |
(2) Provide employees, assigned to provide permit-required confined space rescue and emergency services, with:
• Personal protective equipment (PPE) needed for safe entry.
• Other equipment required to conduct rescues safely.
• Training so they are:
– Proficient in the use of the PPE and other equipment.
– Proficient as an entrant of permit-required confined spaces.
– Able to safely perform assigned rescue and emergency duties.
– Knowledgeable in basic first aid and cardiopulmonary resuscitation (CPR).
• Practice sessions for permit-required confined space rescues at least once every twelve months where dummies, manikins, or actual persons are removed from either:
– The actual permit spaces; or
– Representative permit spaces that simulate the opening size, configuration, and accessibility, of permit spaces where rescue will be performed.
(3) Establish procedures for:
• Contacting rescue and emergency services.
• Rescuing entrants from permit-required confined spaces.
• Providing necessary emergency services to rescued entrants.
• Preventing unauthorized persons from attempting a rescue.
[]
You must:
• Use nonentry retrieval systems or methods to rescue entrants in a permit-required confined space unless this:
– Would increase the overall risk of injury to entrants; or
– Would not contribute to the rescue of the entrant.
• Make sure each entrant uses a chest or full-body harness, with a retrieval line attached to the harness at one of the following locations:
– At the center of the employee's back, near shoulder level.
– Above the employee's head.
– At another point which presents a profile small enough for the successful removal of the employee.
• Attach the retrieval line to a mechanical device or fixed point outside the space, so rescue can begin as soon as necessary.
• Make sure a mechanical device is available to retrieve entrants from vertical spaces more than five feet (1.52 m) deep.
| Note: | When you can demonstrate that the use of a chest or full-body harness is not feasible or creates a greater hazard, then you may use wristlets or another method shown to be the safest and most effective alternative. |
[]
You must:
• Make sure that an entry supervisor:
– Authorizes the entry into a permit-required confined space by signing the entry permit.
– Oversees entry operations.
– Knows about the hazards that may be faced during entry, including the mode, signs or symptoms, and consequences of the exposure.
– Verifies and checks all of the following:
&sqbul; The appropriate entries have been made on the permit.
&sqbul; All tests specified by the permit have been conducted.
&sqbul; All procedures and equipment specified by the permit are in place before approving the permit and allowing entry to the space.
– Terminates the entry and cancels the permit when:
&sqbul; The assigned task or job has been completed.
&sqbul; A condition in the space that is not covered by the entry permit is discovered.
– Verifies that rescue services are available and that there is a way to contact them.
– Removes unauthorized individuals who enter or attempt to enter the permit-required confined space during entry operations.
– Determines that entry operations remain consistent with the terms of the entry permit and acceptable entry conditions are maintained:
&sqbul; Whenever responsibility for a permit-required space entry operation is transferred; and
&sqbul; At regular intervals dictated by the hazards and operations performed within the space.
| Note: | • Make sure entry supervisors have the required knowledge and proficiency to perform the job duties and responsibilities required by this part. |
| • The entry supervisor may also perform other duties under this part, such as attendant or entrant, if they are trained and proficient in those duties. | |
| • The responsibility of the entry supervisor may be passed from one supervisor to another during an entry operation. |
[]
IMPORTANT:
• The number of attendants assigned should be tailored to the requirements of the space and the work performed.
• You need to assess if it is appropriate or possible to have multiple permit spaces monitored by a single attendant, or have an attendant stationed at a location outside each space. Video cameras and radios are examples of tools that may assist an attendant monitoring more than one space.
• Attendants may be stationed at any location outside the permit-required confined space if the duties described in this section can be effectively performed for each space that is monitored.
You must:
• Provide at least one attendant outside the permit-required confined space during entry operations.
• Make sure each permit-required confined space attendant:
– Understands the hazards that may be faced during entry, including the mode, signs or symptoms, and results of exposure to the hazards.
– Is aware of the behavioral effects of exposure to the hazard.
– Continuously maintains an accurate count of entrants in the space.
– Maintains an accurate record of who is in the permit-required confined space.
– Communicates with entrants as necessary to monitor their status or alert them of the need to evacuate the space.
– Monitors activities inside and outside the space to determine if it is safe for entrants to remain in the space.
– Orders entrants to evacuate the space immediately if any of the following conditions occur:
&sqbul; A prohibited condition.
&sqbul; The behavioral effects of hazardous exposure on an entrant.
&sqbul; A situation outside the space that could endanger entrants.
&sqbul; The attendant cannot effectively and safely perform all the duties required in this part.
– Takes the following actions when unauthorized persons approach or enter a space:
&sqbul; Warns unauthorized persons to stay away from the space.
&sqbul; Tells the unauthorized persons to exit immediately if they have entered the space.
&sqbul; Informs entrants and the entry supervisor if unauthorized persons have entered the space.
– Performs nonentry rescues as specified by your rescue procedure.
– Has the means to respond to an emergency affecting one or more of the permit spaces being monitored without preventing performance of the attendant's duties to the other spaces being monitored.
– Carries out no duties that might interfere with their primary duty to monitor and protect the entrants.
– Calls for rescue and other emergency services as soon as entrants may need assistance to escape from the space.
– Monitors entry operations until relieved by another attendant or all entrants are out of the space.
[]
You must:
• Make sure that all entrants:
– Know the hazards they may face during entry, including the mode, signs or symptoms, and results of exposure to the hazards.
– Use equipment properly.
– Communicate with the attendant as necessary so the attendant can:
&sqbul; Monitor entrant status.
&sqbul; Alert entrants of the need to evacuate.
– Alert the attendant whenever either of these situations exist:
&sqbul; A warning sign or symptom of exposure to a dangerous situation such as, behavioral changes, euphoria, giddiness potentially from lack of oxygen or exposure to solvents.
&sqbul; A prohibited condition.
– Exit from the permit-required confined space as quickly as possible when one of the following occurs:
&sqbul; The attendant or entry supervisor gives an order to evacuate.
&sqbul; The entrant recognizes any warning sign or symptom of exposure to a dangerous situation.

&sqbul; An evacuation alarm is activated.
[]
You must:
• Make sure you terminate the entry when entry operations are completed, including securing an entrance cover and canceling the permit.
[]
Summary:
Your responsibility:
To choose alternate entry procedures for spaces where the only hazard is a hazardous atmosphere.
IMPORTANT:
In addition to this section, you also need to meet the requirements in the following sections of this part:
– WAC 296-307-644, Identifying and controlling permit-required confined spaces.
– WAC 296-307-646, Permit-required confined space program.
– WAC 296-307-648, Employee training.
You must:
Make sure the following conditions are met if using alternate entry procedures.
Follow these alternate entry procedures for permit-required confined spaces.
[]
You must:
• Make sure, when using alternate entry procedures, instead of permit entry procedures, that you have monitoring and inspection data that supports the following:
– That the only hazard of the permit-required confined space is an actual or potentially hazardous atmosphere.
– That continuous forced air ventilation alone is all that is needed to maintain the permit-required confined space for safe entry.
• Make sure an entry to obtain monitoring and inspection data or to eliminate hazards is performed according to WAC 296-307-500, Permit entry procedures.
• Make sure all documentation produced is available to each affected employee and their authorized representative.
[]
You must:
• Use the following alternate entry procedures:
– Eliminate any unsafe conditions before removing an entrance cover.
&sqbul; When entrance covers are removed, promptly guard the opening with a railing, temporary cover, or other temporary barrier to prevent accidental falls through the opening and protect entrants from objects falling into the space.
&sqbul; Certify that preentry measures have been taken (such as safe removal of the cover and having protection needed to gather preentry data), with the date, location of the space, and signature of the person certifying.
• Make the preentry certification available before entry to each entrant.
– Before an employee enters the confined space, test the internal atmosphere with a calibrated, direct-reading instrument for all of the following, in this order:
&sqbul; Oxygen content.
&sqbul; Flammable gases and vapors.
&sqbul; Potential toxic air contaminants.
– Provide entrants, or their authorized representatives, with an opportunity to observe the preentry and periodic testing.
– Make sure the atmosphere within the space is not hazardous when entrants are present.
– Use continuous forced air ventilation, as follows:
&sqbul; Wait until the forced air ventilation has removed any hazardous atmosphere before allowing entrants into the space.
&sqbul; Direct forced air ventilation toward the immediate areas where employees are, or will be, and continue ventilation until all employees have left the space.
• Provide the air supply from a clean source and make sure it does not increase hazards in the space.
– Test the atmosphere within the space as needed to make sure hazards do not accumulate.
– If a hazardous atmosphere is detected during entry, do all of the following:
&sqbul; Evacuate employees from the space immediately.
&sqbul; Evaluate the space to determine how the hazardous atmosphere developed.
&sqbul; Implement measures to protect employees from the hazardous atmosphere before continuing the entry operation.
&sqbul; Verify the space is safe for entry before continuing the entry operation.
[]
Summary:
IMPORTANT:
A confined space may be classified as a nonpermit confined space for as long as the hazards remain eliminated. Once a hazard is present, you must follow all requirements of this part that apply.
Your responsibility:
To make sure any space you classify as nonpermit does not have the potential to contain serious health or safety hazards.
You must:
Follow these requirements when classifying a confined space as a nonpermit confined space.
Reevaluate nonpermit confined spaces if hazards develop.
[]
You must:
• Make sure the confined space meets these conditions to be classified as nonpermit confined spaces:
– The confined space does not contain an actual or potential hazardous atmosphere.
– The confined space does not contain hazards capable of causing death or serious physical harm. This includes any recognized health or safety hazards including engulfment in solid or liquid material, electrical shock, or moving parts.
– If you must enter to remove hazards, the space must be treated as a permit-required confined space until hazards have been eliminated.
| Note: | • Controlling atmospheric hazards through forced air ventilation does not eliminate the hazards. |
| • You should evaluate the use of lockout-tagout, as covered in WAC 296-307-320, to determine if using it fully eliminates the hazard. | |
| • You are allowed to use alternate entry procedures covered in WAC 296-307-652, if you can demonstrate that forced air ventilation alone will control all hazards in the space. |
• Document how you determined the confined space contained no permit-required confined space hazards. Certify this documentation with the following:
– Date.
– Location of the space.
– Signature of the person making the determination.
• Make the certification available to each entrant, or their authorized representative.
| Note: | This certification must be completed every time a permit-required confined space is reclassified as a nonpermit space. |
[]
You must:
• Reclassify a nonpermit confined space to a permit-required confined space, if necessary, when changes in the use or configuration of the space increase the hazards to entrants.
• Make sure all employees exit the space if hazards develop. You must then reevaluate the space and determine whether it must be reclassified as a permit-required confined space.
[]
Acceptable entry conditions:
The conditions that must exist in a permit-required confined space to allow safe entry and work.
Attendant:
An individual stationed outside one or more permit-required confined spaces to monitor the entrants.
Blanking or blinding:
The absolute closure of a pipe, line, or duct by fastening a solid plate (such as a spectacle blind or a skillet blind) that completely covers the bore. It is capable of withstanding the maximum pressure of the pipe, line, or duct with no leakage beyond the plate.
Confined space:
A space that is all of the following:
• Large enough and arranged so an employee could fully enter the space and work.
• Has limited or restricted entry or exit. Examples of spaces with limited or restricted entry are tanks, vessels, silos, storage bins, hoppers, vaults, excavations, and pits.
• Not primarily designed for human occupancy.
Double block and bleed:
The closure of a line, duct, or pipe by closing and locking or tagging two in-line valves and by opening and locking or tagging a drain or vent valve in the line between the two closed valves.
Emergency:
Any occurrence (including any failure of hazard control or monitoring equipment) or event internal or external to the permit-required confined space that could endanger authorized entrants.
Engulfment:
The surrounding capture of a person by a liquid or finely divided (flowable) solid substance that can be inhaled to cause death by filling or plugging the respiratory system or that can exert enough force on the body to cause death by strangulation, constriction, or crushing.
Enter (entry):
The action by which a person passes through an opening into a permit-required confined space and includes work activities in that space. Entry is considered to have occurred as soon as any part of the entrant's body breaks the plane of an opening into the space.
| Note: | If the opening is large enough for the worker to fully enter the space, a permit is required even for partial body entry. Permits are not required for partial body entry where the opening is not large enough for full entry, although other rules such as lockout-tagout, WAC 296-307-320 or respiratory hazards, WAC 296-307-624 may apply. |
An employee who is authorized by the employer to enter a permit-required confined space.
Entry permit (permit):
The written or printed document that is provided by you to allow and control entry into a permit-required confined space and that contains the information required in WAC 296-307-650, Permit entry procedures.

• Authorizing entry and overseeing entry operations; and
• Terminating entry as required.
Hazardous atmosphere:
An atmosphere that may expose employees to the risk of death, incapacitation, impairment of ability to self-rescue (that is, escape unaided from a permit-required confined space), injury, or acute illness caused by one or more of the following:
• Flammable gas, vapor, or mist in excess of ten percent of its lower flammable limit (LFL).
• Airborne combustible dust at a concentration that meets or exceeds its LFL.
| Note: | This concentration may be approximated as a condition in which the dust obscures vision at a distance of five feet (1.52 m) or less. |
• Atmospheric concentration of any substance which may exceed a permissible exposure limit. For additional information about atmospheric concentration, see chapter 296-62 WAC, Parts F, G, and I, General occupational health standards and WAC 296-307-624, Respiratory hazards.
| Note: | An airborne concentration of a substance that is not capable of causing death, incapacitation, impairment of ability to self-rescue, injury, or acute illness due to its health effects is not covered by this definition. |
| Note: | You can find guidance on establishing acceptable atmospheric conditions for air contaminants, which have no WISHA-determined doses or permissible exposure limits using other sources of information, such as: |
| • Material safety data sheets required by WAC 296-307-550, Employer chemical hazard communication. | |
| • Published information. | |
| • Internal documents. |
A written authorization to perform operations, for example, riveting, welding, cutting, burning, and heating, that can provide a source of ignition.

Any of the following conditions:
• An immediate or delayed threat to life.
• Anything that would cause irreversible adverse health effects.
• Anything that would interfere with an individual's ability to escape unaided from a permit-required confined space.
| Note: | Some materials - hydrogen fluoride gas and cadmium vapor, for example - may produce immediate transient effects that, even if severe, may pass without medical attention, but are followed by sudden, possibly fatal collapse twelve to seventy-two hours after exposure. The victim "feels normal" after recovery from transient effects until collapse. Such materials in hazardous quantities are considered to be "immediately" dangerous to life or health (IDLH). |
The displacement of the atmosphere in a permit-required confined space by a noncombustible gas (such as nitrogen) to such an extent that the resulting atmosphere is noncombustible.
| Note: | This procedure produces an IDLH oxygen-deficient atmosphere. |
The process by which a permit-required confined space is removed from service and completely protected against the release of energy and material into the space by such means as: Blanking or blinding; misaligning or removing sections of lines, pipes, or ducts; a double block and bleed system; lockout or tagout of all sources of energy; or blocking or disconnecting all mechanical linkages.
Line breaking:
The intentional opening of a pipe, line, or duct that is or has been carrying flammable, corrosive, or toxic material, an inert gas, or any fluid at a volume, pressure, or temperature capable of causing injury.
Nonpermit confined space:

• Contains any physical hazard. This includes any recognized health or safety hazards including engulfment in solid or liquid material, electrical shock, or moving parts.
• Contains any other recognized serious safety or health hazard that could either:
– Impair the ability to self-rescue; or
– Result in a situation that presents an immediate danger to life or health.
Permit-required confined space program:
An overall program for:
• Controlling and appropriately protecting employees from permit-required confined space hazards; and
• Regulating employee entry into permit-required confined spaces.
Prohibited condition:
Any condition in a permit-required confined space that is not allowed by the permit during the authorized entry period.
Rescue service:
The personnel designated to rescue employees from permit-required confined spaces.
Retrieval system:
The equipment used for nonentry rescue of persons from permit-required confined spaces, such as a retrieval line, full-body harness or wristlets, and a lifting device or anchor.
Testing:
The process of identifying and evaluating the hazards that entrants may be exposed to in a permit-required confined space. Testing includes specifying the tests that are to be performed in the permit-required confined space.
| Note: | Testing allows employers to devise and implement adequate controls to protect entrants during entry, and to determine if acceptable entry conditions are present. |

Emergency Response
NEW SECTION
WAC 296-307-704
Scope.
What is the purpose of WAC 296-307-704, Emergency response to hazardous substance
releases?
To state the minimum requirements that help you protect the safety and health of your employees during a response to hazardous substance releases in your workplace or any other location.
Do the requirements of this rule apply to your workplace?
This section applies if your employees are, or could become, involved in responding to uncontrolled releases of hazardous substances in your workplace or any other location. Use the scope flow chart, and definitions that follow, to determine if this section applies to your workplace(s). Defined words are italicized in the flow chart.
| Couldn't make gif for \\skagit\images\WSR\05-03\PERM\WAC296-307-704_01.tif
|
*The flow chart references other rules applicable to your workplace depending on conditions and hazards.
Examples include:
• WAC 296-62-400, Hazardous chemicals in laboratories
• WAC 296-307-594, Respiratory protection.
Definitions applicable to the flow chart (see WAC 296-307-70480 for additional definitions used in this section):
Danger area
Areas where conditions pose a serious danger to employees, such as areas where:
• Immediately dangerous to life or health (IDLH) conditions could exist
OR
• High levels of exposure to toxic substances could exist
OR
• There is a potential for exceeding the lower explosive limit (LEL), also known as the lower flammability limit (LFL), of a substance.
Emergency response
A response to an anticipated release of a hazardous substance that is, or could become, an uncontrolled release.
Hazardous substance
Any biological, radiological, or chemical substance that can have adverse effects on humans. (See WAC 296-307-70480 for a more specific definition.)
Immediately dangerous to life or health (IDLH)
Any atmospheric condition that would:
• Cause an immediate threat to life
• Cause permanent or delayed adverse health effects
• Interfere with an employee's ability to escape.
Incidental release
A release that can be safely controlled at the time of
the release and does not have the potential to become an
uncontrolled release.
A tanker truck is receiving a load of hazardous liquid when a leak occurs. The driver knows the only hazard from the liquid is minor skin irritation. The employer has trained the driver on procedures and provided equipment to use for a release of this quantity. The driver puts on skin protection and stops the leak. A spill kit is used to contain, absorb, and pick up the spilled material for disposal.
Limited action
Action necessary to:
• Secure an operation during emergency responses,
OR
• Prevent an incident from increasing in severity.
Examples include shutting down processes and closing emergency valves.
Release
A spill, leak, or other type of hazardous substance discharge.
Uncontrolled release
A release where significant safety and health risks could
be created. Releases of hazardous substances that are either
incidental or could not create a safety or health hazard
(i.e., fire, explosion or chemical exposure) are not
considered to be uncontrolled releases.
• Large-quantity releases
• Small-releases that could be highly toxic
• Airborne exposures that could exceed a WISHA permissible exposure limit or a published exposure limit and employees are not adequately trained or equipped to control the release.
A forklift driver knocks over a container of a solvent-based liquid, releasing the contents onto the warehouse floor. The driver has been trained to recognize the vapor is flammable and moderately toxic when inhaled. The driver has not been trained or provided appropriate equipment to address this type of spill. In this situation, it is not safe for the driver to attempt a response. The driver needs to notify someone of the release so an emergency response can be initiated.
Workplace
• A fixed facility
OR
• A temporary location (such as a traffic corridor)
OR
• Locations where employees respond to emergencies.
Summary:
Your responsibility:
To anticipate, plan for, and manage emergency response
operations so employees are protected from hazardous
substances and conditions.
| Note: | Other chapters may apply to your workplace, such as: |
| • Chapter 296-62 WAC, General occupational health standards. |

[]
| Note: | • You may already have an emergency response plan, such as required by chapter 296-843 WAC, Hazardous waste operations or by state and locally coordinated response efforts (Section 303 of Superfund Amendments and Reauthorization Act (SARA), Title III). You may use those plans to comply with this section, if they include the items listed below. |
| • Before a written emergency response plan can be developed, you will need to anticipate the types of uncontrolled releases that employees could encounter in your workplace(s). |
(1) Make sure your plan is written and adequately addresses, as a minimum, all of the following:
• Preemergency planning and coordination with additional responders (including personnel from other employers such as: Fire departments, law enforcement agencies, emergency medical services, and state or federal agencies).
• Personnel roles, (see Table 1) and lines of authority and communications for all affected parties including responders.
• Employee training (see WAC 296-307-70415, train your employees), for more detail:
| Note: | • Responders' level of training depends on the duties and roles the employer assigns. |
| • Training for the employees' role should address the competencies specified in Tables 3 through 6. | |
| • Training on specific substances may be appropriate depending on the number and characteristics of hazardous substances expected to be encountered. For example, if employees may only respond to one substance, you could provide training (covering the knowledge and skills specified in Tables 3 through 6) relevant to that single substance. If employees might respond to a range of hazardous substances, training may be required to cover categories of hazardous substances. |
• Videos and automated training methods (for example: Interactive computer based programs) may be used in training; however, instructors must be readily available to:
– Encourage and provide responses to questions for the benefit of the group
– Evaluate employees' understanding of the material
– Provide instructional interaction to the group.
• Emergency recognition
• Immediate emergency procedures including:
– Methods of alerting employees (see WAC 296-307-345, Employee alarm systems) and outside responders
– Procedures for limited action (emergency prevention).
| Note: | Limited action includes shutting down processes, closing emergency valves and other critical actions to
secure the operation, or prevent the incident from increasing in severity. |
| Limited Action and Employee Roles | |
| If. . . | Then employees involved would be: |
| Limited action could be conducted in the danger area | Considered emergency responders |
| Limited action will not be conducted in IDLH conditions | Considered evacuees, not emergency responders |
• Evacuation routes and procedures
• How to establish safe distances and places of refuge (for example, during emergency response the incident commander (IC) decides to make changes based on new developments, i.e., changes in the wind direction).
You must:
• Methods of securing and controlling access to the site
• Emergency medical treatment and first aid
• A complete personal protective equipment (PPE) program that addresses:
– Selection of PPE including selection criteria to be used and the identification, specified use and limitations of the PPE selected
– Training on proper use of PPE (including maintenance)
– Hazards created by wearing PPE including heat stress during temperature extremes, and/or other appropriate medical considerations
– Criteria used for determining the proper fit of PPE
– Procedures covering proper use of PPE including procedures for inspection, putting it on (donning) and removing it (doffing)
– Maintenance of PPE including procedures for decontamination, disposal and storage
– Methods used to evaluate the effectiveness of your PPE
program.
| Note: | • If a manufacturer's printed information or WISHA rule adequately addresses procedural requirements (such as donning or doffing for PPE), it is not necessary to rewrite this into your program; simply attach the printed information. |
| • You may use written procedures provided by the equipment manufacturer when they meet the requirements of other chapters, including chapter 296-307 WAC, Part Y-5, Respirators. |
– Emergency response procedures
– Decontamination procedures determined by a hazardous materials specialist or other qualified individual
– Methods to critically assess the response and conduct appropriate follow-up.
You must:
(2) Make your written emergency response plan available
to employees, their representatives, and WISHA personnel for
inspecting or copying.
| Note: | In situations where multiple employers could respond to an incident, all plans should consistently address: |
| • Who will be designated as the incident commander (IC) | |
| AND | |
| • If, when, and how transfer of the incident commander (IC) position will take place. |

• Instruction in the wearing of appropriate personal
protective equipment.
| Note: | Skilled support personnel do not need to comply with the other training requirements of this section. |
(2) Make sure the safety and health precautions given to your employees are also given to skilled support personnel.
[]
(1) Identify all hazardous substances and conditions present, within their training level, using site analysis and maximum exposure limits, when appropriate.
(2) Implement emergency response procedures appropriate to the hazardous substances and conditions present, such as:
• Procedures that address the use of engineering controls, hazardous substance handling, and new technologies
• Procedures that address decontamination
• Procedures that address PPE
• Procedures that limit the number of personnel to those who are actively performing emergency response operations, in areas where exposure could exist.
(3) Designate an incident safety officer (ISO).
• Make sure the ISO demonstrates knowledge about operations being implemented at the emergency response site. They must:
– Identify and evaluate hazards
– Communicate with the IC about hazards, immediately informing the IC of corrective actions that must be taken when conditions are judged to be:
&sqbul; An imminent danger
OR
&sqbul; Immediately dangerous to life or health (IDLH).
– Provide direction about the safety of operations.
[]
You must:
• Make sure operations and tasks (including limited actions) in danger areas are conducted using the buddy system in teams of two or more.
Definition:
Danger areas are areas where conditions pose a serious danger to employees, such as areas where:
• Immediately dangerous to life or health (IDLH) conditions could exist.
OR
• High levels of exposure to toxic substances could exist.
OR
• There is a potential for exceeding the lower explosive limit (LEL), also known as the lower flammability limit (LFL) of a hazardous substance.
[]
You must:
(1) Provide stand-by employees equipped with the same
level of personal protective equipment (PPE) as the entrants,
for assistance or rescue.
| Note: | • The buddy system applies to stand-by employees (WAC 296-307-70450). |
| • One of the two stand-by employees can be assigned to another task provided it does not interfere with the performance of the stand-by role. | |
| • Rescue equipment should be selected and provided based on the types of rescue situations that could occur. |
(2) Make sure employees trained in first aid are readily
available with necessary medical equipment and have a way to
transport the injured.
| Note: | • Employers who require their employees to provide first aid must comply with the bloodborne pathogen rule, chapter 296-823 WAC. |
[]
| Note: | • Only properly trained employees should select PPE. Hazardous materials technicians and hazardous materials specialists can select PPE within the competencies specified in Table 4. |
| • Selection requirements in other PPE rules also apply, including: | |
| – Chapter 296-307 WAC, Part Y-5, Respirators. | |
| – Chapter 296-305 WAC, Safety standards for fire fighting. |
• Provide employees with appropriate PPE and make sure it is used if hazards could be present.
• Select PPE (such as respirators, gloves, protective suits and other PPE) based on:

• Hazardous wastes as defined in this section.
Hazardous waste
A substance designated by chapter 173-303 WAC, Dangerous
waste regulations, department of ecology, as a dangerous waste
or an extremely hazardous waste and any waste fitting the
definition of "health hazard" in this section.
| Note: | For department of ecology regulations, visit: http://www.ecy.wa.gov. |
A chemical, a mixture of chemicals, or a pathogen for which there is statistically significant evidence, based on at least one study conducted according to established scientific principles, that acute or chronic health effects may occur in exposed employees.
The term "health hazard" includes stress due to temperature extremes and chemicals that are:
• Carcinogens
• Toxic or highly toxic agents
• Reproductive toxins, irritants, corrosives, sensitizers, hepatotoxins, nephrotoxins, or neurotoxins
• Agents acting on the hematopoietic system agents that damage lungs, skin, eyes, or mucous membranes. (Detailed definitions of these chemical terms can be found in the Safety and health core rules, WAC 296-307-550, chemical hazard communication.)
Immediately dangerous to life or health (IDLH)
Any atmospheric condition that would:
• Cause an immediate threat to life
OR
• Cause permanent or delayed adverse health effects
OR
• Interfere with an employee's ability to escape.
Incident command system (ICS)
An organized approach to control and manage operations at an emergency response incident.
Incidental release
A release that can be safely controlled at the time of the release and does not have the potential to become an uncontrolled release.
| Note: | Example of a situation that results in an incidental release: |
| A tanker truck is receiving a load of hazardous liquid when a leak occurs. The driver knows the only hazard from the liquid is minor skin irritation. The employer has trained the driver on procedures and provided equipment to use for a release of this quantity. The driver puts on skin protection and stops the leak. A spill kit is used to contain, absorb, and pick up the spilled material for disposal. |
Action necessary to:
• Secure an operation during emergency responses,
OR
• Prevent an incident from increasing in severity.
Examples include shutting down processes and closing emergency valves.
Lines of authority
A preestablished ranking of individuals, qualified to assume a commanding role during an emergency response, noted in an emergency response plan and implemented during a response. This is most important when responders from multiple employers could participate in an emergency response.
Lower explosive limit (LEL)
See lower flammable limit (LFL).
Lower flammable limit (LFL)
The lowest concentration of a material that will propagate a flame. The LFL is usually expressed as a percent (by volume) of the material in air (or other oxidant).
Must
Must means mandatory.
Permissible exposure limit (PEL)
Means the established time-weighted-average (TWA) concentration or ceiling concentration of a contaminant that must not be exceeded.
The exposure, inhalation, or dermal permissible limit specified in chapter 296-307 WAC, Part Y-6, Respiratory hazards.
Personal protective equipment (PPE)
Protective items designed to be worn by the user to protect them against airborne, skin contact and other hazards. This includes items such as respiratory protection, protective suits, gloves, eye protection, etc.
Postemergency response
The stage of the emergency response where the immediate threat from the release has been stabilized or eliminated, and cleanup of the site has started.
Published exposure level
Exposure limits published in "National Institute for Occupational Safety and Health (NIOSH) Recommendations for Occupational Safety and Health" (DHHS publication #92-100, 1992).
If an exposure limit is not published by NIOSH, then
"published exposure level" means the exposure limits published
by the American Conference of Governmental Industrial
Hygienists (ACGIH) in "TLVs and BEIs-Threshold Limit Values
for Chemical Substances and Physical Agents" (1999 edition).
| Note: | Additional exposure levels published by recognized organizations such as the American Industrial Hygiene Association are not required to be observed by this rule; however, they may be a useful resource when a hazardous substance is not covered by NIOSH and ACGIH publications. |
A spill, leak, or other type of hazardous substance discharge.
Uncontrolled release
A release where significant safety and health risks could be created. Releases of hazardous substances that are either incidental or could not create a safety or health hazard (i.e., fire, explosion or chemical exposure) are not considered to be uncontrolled releases.
Examples of conditions that could create a significant safety
and health risk:
Large-quantity releases
Small releases that could be highly toxic
Airborne exposures that could exceed a WISHA permissible
exposure limit or a published exposure limit and employees are
not adequately trained or equipped to control the release.
Example of an uncontrolled release:
A forklift driver knocks over a container of a solvent-based liquid, releasing the contents onto the warehouse floor. The driver has been trained to recognize the vapor is flammable and moderately toxic when inhaled. The driver has not been trained or provided appropriate equipment to address this type of spill. In this situation, it is not safe for the driver to attempt a response. The driver needs to notify someone of the release so an emergency response can be initiated.
Workplace
• A fixed facility
OR
• A temporary location (such as a traffic corridor)
OR
• Locations where employees respond to emergencies.
