PROPOSED RULES

DEPARTMENT OF

LABOR AND INDUSTRIES

[ Filed July 20, 2004, 9:02 a.m. ]

     Original Notice.

     Preproposal statement of inquiry was filed as WSR 04-09-097 on April 20, 2004.

     Title of Rule and Other Identifying Information: Safety standards for agriculture, chapters 296-62 and 296-307 WAC, the Department of Labor and Industries 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 rules "in one volume." The occupational health requirements in chapter 296-62 WAC are the focus of this effort. Several rules from this chapter were recently rewritten for clarity as part of the agency's plain language initiative. This rule making proposes to also add these rules to the agriculture safety standard chapter 296-307 WAC.

     There are no new requirements in the proposed amendments, although references to other chapters and sections of chapter 296-307 WAC will be updated where needed. Some additional reorganization of requirements will also be done for better navigation of the rule.

     Submit Written Comments to: Cindy Ireland, Project Manager, Department of Labor and Industries, WISHA Division, P.O. Box 44620, Olympia, WA 98540-4620, fax (360) 902-5529, by October 8, 2004.

     Assistance for Persons with Disabilities: Contact Sally Elliott by September 9, 2004, TTY (360) 902-5484 or yous235@lni.wa.gov.

     Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: There are no new requirements in the proposed amendments, although references to other chapters and sections of chapter 296-307WAC will be updated where needed. Some additional reorganization of requirements will also be done for better navigation of the rule.

     Reasons Supporting Proposal: The Department of Labor and Industries 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 rules "in one volume."

     Statutory Authority for Adoption: RCW 49.17.010, 49.17.040, 49.17.050, 49.17.060.

     Statute Being Implemented: Chapter 49.17 RCW.

     Rule is not necessitated by federal law, federal or state court decision.

     Name of Proponent: Department of Labor and Industries, governmental.

     Name of Agency Personnel Responsible for Drafting: Tracy Spencer, Tumwater, (360) 902-5530; Implementation and Enforcement: Michael A. Silverstein, Tumwater, (360) 902-5495.

     No small business economic impact statement has been prepared under chapter 19.85 RCW. A number of criteria and exemptions were established by the small business economic impact statement (SBEIS) analysis. One key criteria that allows rule changes to be exempt from preparation of an SBEIS is presented in RCW 34.05.310 (4)(d): "rules that only correct typographical errors, make address or name changes, or clarify language of a rule without changing its effect" are not subject to the SBEIS requirements. Because the proposed rule changes make clarifying and organizational changes for ease of understanding and use, but do not in any way alter the content of the original rules, there should not be an economical impact on Washington state business.

     A cost-benefit analysis is not required under RCW 34.05.328. The analysis of the rule reveals that in addition to not imposing new costs on businesses, these revisions will actually make WISHA rules easier for employers and employees to understand and use, and thus actually save them time.

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 ((Chemical hazard communication for manufacturers, importers and distributors, WAC 296-62-054)) Material safety data sheets and label preparation, WAC 296-307-560 through 296-307-56050.
• 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.

NEW SECTION
WAC 296-307-59805   Make sure voluntary use of respirators is safe.  

     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.
     You must:

     (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.
     You must:

     (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.
     Use Table 2 to provide information to employees who voluntarily use any type of respirator.

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.

WAC 296-307-602   Respirator selection.  

     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.

[]


NEW SECTION
WAC 296-307-60205   Select and provide appropriate respirators.  

     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:

Respirator Selection Process
     Step 1: If your only respirator use is for escape, skip to Step 8 to select appropriate respirators.

     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.
     Step 6: Select an appropriate respirator from one of the following respirators for IDLH conditions and skip to Step 8:     • Full-facepiece, pressure demand, self-contained breathing apparatus (SCBA) certified by NIOSH for a minimum service life of thirty minutes

     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 7: Identify respirator types with assigned protection factors (APFs) from Table 5 that are appropriate to protect employees from the expected exposure concentration.

     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.
     Use Table 5 to identify the assigned protection factor for different types of respirators.

     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.
     IMPORTANT:

     • 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.

[]


NEW SECTION
WAC 296-307-60405   Provide medical evaluations.  

     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.

Medical Evaluation Process
     Step 1: Identify employees who need medical evaluations AND determine the frequency of evaluations from Table 7. Include employees who:

     • 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.
     Step 2: Identify a licensed healthcare professional (LHCP) to perform your medical evaluations.

Note: If you select a different LHCP, you do not need to have new medical evaluations done.
     Step 3: Make sure your LHCP has the following information before the evaluation is completed:

     • 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

     – Additional personal protective clothing and equipment to be worn

     – 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.
     Step 4: Administer the medical questionnaire in WAC 296-307-61605 to employees, OR provide them a medical exam that obtains the same information.

Note: You may use on-line questionnaires if the questions are the same and requirements of this section are met.
     • Administer the examination or questionnaire at no cost to employees:

     – 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.
     • Make sure employees understand the content of 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.
     Step 6: Obtain a written recommendation from the LHCP that contains only the following medical information:

     • Whether or not the employee is medically able to use the respirator

     • Any limitations of respirator use for the employee

     • What future medical evaluations, if any, are needed

     • A statement that the employee has been provided a copy of the written recommendation.

     Step 7: Provide a powered, air-purifying respirator (PAPR) when the LHCP determines the employee should not wear a negative-pressure air-purifying respirator AND is able to wear a PAPR.

Reference: See WAC 296-307-602 for requirements regarding selection of air-purifying respirators.
Note: • You may discontinue medical evaluations for an employee when the employee no longer uses a respirator.
• If you have staff conducting your medical evaluations, they may keep completed questionnaires and findings as confidential medical records, if they are maintained separately from other records.
     Use Table 7 to determine medical evaluation frequency.

Table 7
Evaluation Frequency

Type of Evaluation: When required:
Initial medical evaluations • Before respirators are fit-tested or used in the workplace.
Subsequent medical evaluations • If any of these occur:
– Your licensed healthcare professional (LHCP) recommends them; for example, periodic evaluations at specified intervals.
– A respirator program administrator or supervisor informs you that an employee needs reevaluation.
– Medical signs or symptoms (such as breathing difficulties) are:
&sqbul; Observed during fit-testing or program evaluation
OR
&sqbul; Reported by the employee
– Changes in worksite conditions such as physical work effort, personal protective clothing, or temperature that could substantially increase the employee's physiological stress.

     &sqbul; An employee notifies you, or your LHCP, that the respirator fit is unacceptable. During the retest, you must give an employee reasonable opportunity to select a different respirator facepiece (size, model, etc.).

Note: You may accept a fit test completed by a previous employer IF:
• You obtain written documentation of the fit test
AND
• The results of the fit test are not more than twelve months old
AND
• The employee will use the same respirator (the same type, model, style, and size)
AND
• The fit test was conducted in a way that meets the requirements of WAC 296-307-606 and 296-307-62010.
     You must:

     • Select an appropriate fit-testing procedure from WAC 296-307-62010 of this part AND:

     – Use quantitative fit-test methods when a negative pressure respirator will be used in concentrations requiring a protection factor greater than 10. This includes:

     &sqbul; Full facepiece air-purifying respirators

     &sqbul; SCBAs operated in demand (negative pressure) mode

     &sqbul; Air-line respirators operated in demand mode.

     – Make sure PAPRs, SCBAs, or air-line respirators are fit tested in negative-pressure mode.

     • Make sure the person conducting fit testing is able to do ALL of the following:

     – Prepare test solutions if required

     – Make sure equipment works properly

     – Perform tests properly

     – Recognize invalid tests

     – Calculate fit factors properly if required.

Note: • No specific training program or certification is required for those who conduct fit tests.
• You should consider evaluating these individuals to determine their proficiency in the fit-testing method to be used.
• You can use an evaluation form such as the form included in the American National Standard for Respirator Fit Testing Methods, ANSI/AIHA Z88.10-2001 to determine if the individual meets these requirements. Visit www.ansi.org or www.aiha.org.

     – 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.
     You must:

     • 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%.
     You must:

     • 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.

NEW SECTION
WAC 296-307-61615   Make sure compressors do not create a hazardous breathing air supply.  

     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.
     You must:

     (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.
     You must:

     (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).
     You must:

     • 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.

NEW SECTION
WAC 296-307-62010   Follow these fit-testing procedures for tight-fitting 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.
     You must:

     • 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

     ♦ Controlled negative pressure (CNP) such as the FitTester 3000™, in Table 17

     ♦ 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.

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.
9. Instruct the employee to:
• 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 14

Bitrex™ Aerosol Test Procedure
Important!
• This is a qualitative fit-test (QLFT) procedure
• Bitrex™ (denatonium benzoate) is routinely used as a taste aversion agent in household liquids that children shouldn't drink and is endorsed by the American Medical Association, the National Safety Council, and the American Association of Poison Control Centers
• The employee must NOT eat, smoke, chew gum or drink anything but plain water for at least fifteen minutes BEFORE the fit test.

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

Fit-Test Exercises
Important:
• This list applies when you use any fit test
• Employees tested must perform ALL exercises marked with an "X" as described for the fit-test procedure used
– Once exercises begin, any adjustments made void the test AND you must begin again
– After test exercises are completed, you must ask the employee about the comfort of the respirator. If it has become unacceptable, have the employee choose another one for testing
• When the controlled negative pressure procedure is used, STOP and repeat the test if the employee adjusts the respirator OR takes a breath and fails to hold it for 10 seconds
• Controlled negative pressure tests conducted according to the method published in 29 CFR 1910.134, Appendix A are an acceptable alternative to the method outlined below.

1The Rainbow Passage:
"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."

WAC 296-307-62015   Follow procedures established for cleaning and disinfecting respirators.  

     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.

NEW SECTION
WAC 296-307-62020   Follow procedures established for seal checking respirators.  

     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.

NEW SECTION
WAC 296-307-62605   Identify and evaluate respiratory hazards.  

     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.
     You must:

     • 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

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.

NEW SECTION
WAC 296-307-62610   Control employee exposures.  

     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.

NEW SECTION
WAC 296-307-62615   Use respirators.  

     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.

WAC 296-307-62620   Notify employees.  

     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

WAC 296-307-62625   Permissible exposure limits of air contaminants.  

     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

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.

NEW SECTION
WAC 296-307-63205   Conduct employee noise exposure monitoring.  

     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.
     You must:

     • 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.

[]


NEW SECTION
WAC 296-307-63210   Control employee noise exposures that equal or exceed 90 dBA TWA8.  

     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.

[]


NEW SECTION
WAC 296-307-63215   Make sure employees use hearing protection when their noise exposure equals or exceeds 85 dBA TWA8.  

     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.
     You must:

     • 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

     • In addition to protection based on daily noise dose, make sure hearing protection has an NRR of at least 20 dB when exposures involve noise that equals or exceeds 115 dBA (slow response sound level meter) or 140 dBC (fast response sound level meter).

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.

[]


NEW SECTION
WAC 296-307-63220   Make sure exposed employees receive training about noise and hearing protection.  

     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.

[]


NEW SECTION
WAC 296-307-63225   Make sure warning signs are posted for areas where noise levels equal or exceed 115 dBA.  

     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.

[]


NEW SECTION
WAC 296-307-63230   Arrange for oversight of audiometric testing.  

     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.

[]


NEW SECTION
WAC 296-307-63235   Identify and correct deficiencies in your hearing loss prevention program.  

     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.
     You must:

     • 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.

[]


NEW SECTION
WAC 296-307-63240   Document your hearing loss prevention activities.  

     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.

• 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.
     You must:

     • 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.

NEW SECTION
WAC 296-307-63410   Measure employee noise exposure.  

     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

[]


NEW SECTION
WAC 296-307-63415   Use these equations when estimating full-day noise exposure from sound level measurements.  

     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 TESTING
NEW SECTION
WAC 296-307-636   Summary.  

     Your 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

     WAC 296-307-63605

     Establish a baseline audiogram for each exposed employee

     WAC 296-307-63610

     WAC 296-307-63635.

[]


NEW SECTION
WAC 296-307-63605   Provide audiometric testing at no cost to employees.  

     You must:

     • Provide audiograms, including any required travel or necessary additional examinations or testing, at no cost to exposed employees.

[]


NEW SECTION
WAC 296-307-63610   Establish a baseline audiogram for each exposed employee.  

     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.
     You must:

     • 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.

[]


NEW SECTION
WAC 296-307-63615   Conduct annual audiograms.  

     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.
     You must:

     • 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.

[]


NEW SECTION
WAC 296-307-63620   Review audiograms that indicate 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.

[]


NEW SECTION
WAC 296-307-63625   Keep the baseline audiogram without revision, unless annual audiograms indicate a persistent threshold shift or a significant improvement in hearing.  

     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.

[]


NEW SECTION
WAC 296-307-63630   Make sure a record is kept of audiometric tests.  

     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; 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.

[]


NEW SECTION
WAC 296-307-63635   Make sure audiometric testing equipment meets these requirements.  

     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

OPTIONS TO AUDIOMETRIC TESTING
NEW SECTION
WAC 296-307-638   Summary.  

     Your 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

     WAC 296-307-63805

     Make sure staff conducting audits are properly trained

     WAC 296-307-63810

     Assess the hearing protection used by each employee during audits

     WAC 296-307-63815

     Document your hearing protection audits

     WAC 296-307-63820

     Third-Party Audiometric Testing

     You must:

     Make sure third-party hearing loss prevention programs meet the following requirements

     WAC 296-307-63825

     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.

[]


NEW SECTION
WAC 296-307-63805   Conduct hearing protection audits at least quarterly.  

     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.

[]


NEW SECTION
WAC 296-307-63810   Make sure staff conducting audits are properly trained.  

     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.

[]


NEW SECTION
WAC 296-307-63815   Assess the hearing protection used by each employee during audits.  

     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.

[]


NEW SECTION
WAC 296-307-63820   Document your hearing protection audits.  

     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 TESTS
NEW SECTION
WAC 296-307-63825   Make sure third-party hearing loss prevention programs meet the following requirements.  

     IMPORTANT:

     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.

NEW SECTION
WAC 296-307-640   Noise definitions.  

     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.

     – 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.

NEW SECTION
WAC 296-307-654   Nonpermit confined spaces requirements.  

     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.

     WAC 296-307-65402

     Reevaluate nonpermit confined spaces if hazards develop.

     WAC 296-307-65404

[]


NEW SECTION
WAC 296-307-65402   Follow these requirements when classifying a confined space as a nonpermit confined space.  

     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.
     You must:

     • 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.

[]


NEW SECTION
WAC 296-307-65404   Reevaluate nonpermit confined spaces if hazards develop.  

     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.

[]


NEW SECTION
WAC 296-307-656   Definitions.  

     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:

     • Atmospheric oxygen concentration below 19.5 percent or above 23.5 percent.

     • 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.
     • Any other atmospheric condition that is immediately dangerous to life or health.

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.
     Hot work permit:

     A written authorization to perform operations, for example, riveting, welding, cutting, burning, and heating, that can provide a source of ignition.

     Immediately dangerous to life or health (IDLH):

     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).
     Inerting:

     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.
     Isolation:

     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:

     A confined space that does NOT contain actual hazards or potential hazards capable of causing death or serious physical harm.

     Oxygen deficient atmosphere:

     An atmosphere containing less than 19.5 percent oxygen by volume.

     Oxygen enriched atmosphere:

     An atmosphere containing more than 23.5 percent oxygen by volume.

     Permit-required confined space or permit space:

     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.

     • 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 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.

Part Y-9

Occupational Exposure to Bloodborne Pathogens
NEW SECTION
WAC 296-307-686   Scope.   This part provides requirements to protect employees from exposure to blood or other potentially infectious materials (OPIM) that may contain bloodborne pathogens. Examples of bloodborne pathogens are the human immunodeficiency virus (HIV) and hepatitis B virus (HBV).

     This part applies to you if you have employees with occupational exposure to blood or OPIM, even if no actual exposure incidents have occurred.

     Definitions:

     Occupational exposure means reasonably anticipated skin, eye, mucous membrane, or parenteral contact with blood or OPIM that may result from the performance of an employee's duties.

     Exposure incident means a specific eye, mouth, other mucous membrane, nonintact skin or parenteral contact with blood or other potentially infectious materials (OPIM) that results from the performance of an employee's duties. Examples of nonintact skin include skin with dermatitis, hangnails, cuts, abrasions, chafing, or acne.

     Parenteral contact occurs when mucous membranes or skin is pierced by needlesticks, human bites, cuts, or abrasions.

Part Y-10

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.

Place illustration here.

*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.

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.
    

     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.

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.


     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.

     You will find some safety and health requirements (for example, personal protective equipment) are addressed on a general level in the core rules, while being addressed for a specific application in this section. When this happens, both requirements apply and should not conflict.

     If you are uncertain which requirements to follow, you must comply with the more protective requirement. Contact your local L&I office if you need assistance in making this determination.

     You must:

NEW SECTION
WAC 296-307-70410   Planning.   Develop an emergency response plan.


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).

     You must:

     (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.

     You must:

     • 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

     • Details of who will evacuate immediately and who will remain behind for limited action

     • 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 equipment

     – 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.

     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.
     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.

     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)

     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.

     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.


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.
