Original Notice.

     Preproposal statement of inquiry was filed as WSR 08-19-073.

     Title of Rule and Other Identifying Information: Chapter 296-155 WAC, Safety standards for construction work, this proposal is to address the requirements that employers must follow with regard to inspection, maintenance and operation of cranes used in the construction industry. This phase will also include updates to our current rigging and personnel lifting requirements. RCW 49.17.400 through 49.17.440 requires the department to establish by rule a crane certification program for cranes used in the construction industry and to establish requirements that must be met to be considered a qualified crane operator. This proposal was developed with the assistance of a stakeholder group from the industry. In addition, the Occupational Safety and Health Administration (OSHA) has adopted their final rule and this proposal also includes requirements OSHA has in their rule in order for the division of occupational safety and health (DOSH) to be at-least-as-effective-as the federal rule. References are also being updated throughout other DOSH standards.

     The following small business economic impact statement (SBEIS) was prepared in compliance with the Regulatory Fairness Act (RFA), RCW 19.85.040, and it provided an analysis comparing the average costs imposed on small businesses and large businesses associated with implementation of WAC 296-155-53302 through 296-155-56435. In particular, the following provisions of the proposed rule, which have been identified as the components likely imposing increased compliance costs¹ on the affected businesses, were analyzed in this report: WAC 296-155-53302 Signal persons qualifications, 296-155-53306 Riggers qualifications, and 296-155-54100 Self-erecting tower cranes -- General.

     1. INTRODUCTION TO THE COST SURVEY

     1.1 Survey methodology:

     To estimate the economic impacts of the proposed Phase 2 crane rule on the affected businesses, L&I developed a survey in April 2011. L&I designed this survey in collaboration with the DOSH crane technical team, assistant attorney general for DOSH, L&I internal survey review committee and other relevant parties. The survey was used to gauge all the probable new compliance costs that businesses would incur if the proposed portion of the crane rule was adopted and to determine whether there exists a disproportionate cost impact on affected small businesses.

     1.1.1 Sampling frame:

     The proposed crane rule applies to all construction and general businesses that own or use cranes and derricks for construction activities. The development of the sampling strategy for the cost survey for the proposed rule requires the identification of the set of businesses that will most likely be affected by the proposed rule changes. To sample the establishments that best represent the underlying population, L&I first obtained a list of crane owners from its crane certification database.

     Next, L&I identified twenty-four industrial subsectors² that most likely would lease cranes from rental companies to perform construction work. Based on these 6-digit NAICS codes, the department extracted the most recent business information data from its administrative data warehouse. By doing this, L&I obtained the population of crane lessees in the construction industry. Together, these two lists constitute the targeted business population that would likely be affected by the proposed rule.

     1.1.2 Sample size:

     In determining the appropriate sample size that was needed to obtain valid cost estimates related to the compliance with the proposed Phase 2 crane and derrick rule, several factors including the desired confidence level, uncertainty in the cost estimates, and the expected response rate were considered.

     First, the conventional level of ninety-five percent confidence and ±5 percent uncertainty were chosen in order to ensure rigorous and statistically valid estimates. Next, approximately twenty-two thousand unique business accounts were pulled from the crane owner list and the crane lessee list as described in 1.1.1 and these businesses comprise the entire population. L&I also weighed in the fact that past rule-making related surveys often had a low response rate.

     The final determination of the sample size for this survey was based on the following factors: (1) The population is approximately twenty-two thousand active employers who will most likely be affected by the proposed rule changes, (2) the desirable confidence level is ninety-five percent (with ± 5 percent sampling error), and (3) the response rate for a similar survey has been relatively low. The department finally chose a sample size of three thousand six hundred thirty-nine to sufficiently yield statistically significant cost estimates, assuming a ten percent response rate and conventional levels for statistical validity.

     1.1.3 Sampling method:

     In order to obtain reliable estimates of compliance costs on the affected businesses, an appropriate sampling method needs to be developed. L&I adopted proportionate stratified random sampling by subsectors for crane lessees and crane owners that don't rent cranes as their main revenue. This method allows the department to create strata at the subsector level that pattern the underlying population, thereby helping to reduce sampling variability. To implement this method, L&I determined the sample size needed for each 6-digit NAICS code by multiplying its proportion of the sampling frame by the overall desired sample size (see Table A2 in the appendix). L&I also randomly selected a certain number of samples from the crane owner list. The final mailing list was obtained by combining the selected samples from the above steps and removing the duplicate records.

     1.1.4 Survey development and response rate:

     The survey was first designed by the regulatory economist in March 2011. The draft was then reviewed by the crane technical team and the AAG from DOSH. Per L&I internal policy, the survey was also submitted to the survey committee for their review. The survey was updated and finalized based on feedback from all the parties involved in April 2011, and it was sent out on May 6, 2011. The survey respondents were required to complete the survey and return it to L&I by the end of May 2011.

     Between May 6 and May 31, 2011, L&I received seven hundred eighty-eight completed surveys from the businesses out of the three thousand six hundred thirty-nine surveys sent. Hence, the response rate for those presumed to have been contacted was 21.7 percent. Six hundred and thirty-five respondents reported that they did not have employees performing as riggers or signal persons, nor did they use any self-erecting tower crane. The remaining one hundred fifty-three employers indicated that at least one section applied to them. There may have been some unsuccessful deliveries due to possible errors in the preparation or the delivery process, so the actual response rate is likely to be higher. Given the short timeframe available to conduct the survey and the fact that no follow-up contacts were made, the response rate is higher than expected.

     1.2 Survey contents:

     The majority of this proposed crane rule is intended to clarify the most current OSHA crane standard or national industrial consensus standard and is not considered as increased requirements to the businesses involved. These components of the rule are not addressed by the survey questions. After comparing the proposed rule with the existing standards and discussing the findings with the AAG and technical team, L&I identified three major requirements that are above current standards and which will probably impose more than minor compliance costs on the businesses involved.

     The survey was organized as follows: The first section of the survey was designed to obtain the background information of each employer including the number of employees, the primary business operations, and the work activities involved; the second through the last sections were designed to estimate the probable new compliance costs relating to each increased requirement. Specifically, the survey plans for the three major estimates required were as follows:

     (1) Estimate the compliance costs relating to riggers qualification requirements.

     The survey will first ask the respondents if they hire any employees to perform the tasks that would require qualified riggers under the proposed rule and if yes, how many of these employees they employ and how many of them are already qualified. The survey next asks them to estimate the costs of providing necessary training, mandatory written and practical tests, along with the evaluation services from a qualified evaluator. The estimated total costs from each respondent will be used to derive the aggregated annual costs of this provision on the affected businesses as a whole.

     (2) Estimate the compliance costs relating to crane signal persons qualification requirements.

     The survey will first ask the respondents if they hire any workers designated as signal persons and if yes, how many of these employees they employ and how many of them are already qualified. The survey then ask[ed] them to estimate the costs of providing necessary training, mandatory oral or written test and practical test, along with the evaluation services from a qualified evaluator. The estimated total costs from each respondent will be used to derive the aggregated annual compliance costs of this provision on the entire affected businesses.

     (3) Estimate the costs of new requirements employers should comply with when they use self-erecting tower cranes to perform construction work.

     The survey will first ask the respondents if they use any self-erecting tower cranes to perform construction work. If yes, it will next ask them approximately how many crane jobs they complete with the use of the self-erecting tower cranes in a typical year. Finally, it will ask them whether they are already in compliance with these two requirements and if not, how much the estimated cost would be for each requirement respectively. The total costs from each respondent the question applies to will be used to derive the aggregated annual costs of this provision on the entire affected businesses.

     2. ASSESSING ECONOMIC IMPACT BY EMPLOYMENT SIZE

     The RFA, RCW 19.85.040(1) requires the department to determine whether a proposed rule will have a disproportionate cost impact on small businesses. The act directs the department to compare "the cost of compliance for small businesses with the cost of compliance for the ten percent of businesses that are the largest businesses required to comply with the proposed rule." A convenient and easy way to make this comparison is to compare the compliance cost per employee for these two groups. For each rule component described in the survey, the unit cost for the small businesses will be compared to the unit cost for the largest ten percent of all businesses in the affected group.

     This SBEIS compares the average cost per affected worker for each component that represents increased requirements. The purpose here is to best estimate the extent to which the disproportionate impact, if any, is on small businesses rather than to estimate the total costs to the affected businesses as a whole.

     2.1 Cost per worker associated with riggers qualification requirements:

     Section 2 in the survey asked respondents whether they have employees performing the tasks that require qualified riggers and if yes, how much the total cost would be if the proposed new qualification requirements were adopted. One hundred and forty-two respondents provided their responses indicating they were subject to this requirement ("YES" to question 2a). Of these one hundred forty-two respondents, seventy-five businesses are small businesses and the remaining are those with more than fifty employees.

     Table 1 shows the costs estimated by each category. For small businesses, the average total cost is $913 for the training fee and additional eight hours of travel time³, $747 for the testing and additional eight hours of travel time, and $577 for the evaluation service from a qualified evaluator. In contrast, the costs are $830, $513 and $280 respectively for the top ten percent of the largest businesses. Since the proposed rule requires that a rigger qualification cannot exceed a five-year period and at a minimum, the renewal must include a documented written exam, a rigger needs to be qualified initially after the rule takes effect and this qualification needs to be renewed twice over an eleven-year time span. If we assume that twenty percent of riggers need to be retrained before retaking the written exam, each renewal would cost $1,134 for small businesses and $703 for the selected large businesses. In total, the annual average cost per rigger is $341 and $233 for these two categories in an eleven-year time span. In light of this, the cost per rigger for small businesses is estimated to be approximately 1.46 times the cost for the ten percent of the largest businesses.

     Section 3 in the survey asked respondents whether they have employees performing the tasks that require qualified signal persons and if yes, how much the total cost would be if the proposed new qualification requirements were adopted. One hundred and thirty-two respondents provided their responses indicating they were subject to this requirement ("YES" to question 3a). Of these one hundred thirty-two respondents, seventy-five businesses are small businesses and the remaining are those with more than fifty employees.

     Table 2 summarizes the costs estimated by each category. For small businesses, the average total cost is $815 for the training fee and additional eight hours of travel time, $658 for the testing and additional eight hours of travel time, and $503 for the evaluation service from a qualified evaluator. In contrast, the costs are $597, $408 and $153 respectively for the top ten percent of the largest businesses. Since OSHA's new crane rule already requires signal persons to be qualified, the only requirement in this proposed rule beyond federal standard is that it requires a signal person's qualification to be renewed every five years. Therefore, the new compliance cost attributed to this rule is the renewal cost. As a signal person's qualification needs to be renewed twice over an eleven-year time span, the annual average cost per signaler is $120 and $58 for these two categories in an eleven-year time span. In light of this, the cost per signaler for small businesses is estimated to be approximately 2.1 times the cost for the ten percent of the largest businesses.

     As of February 2011, there were a total of twenty-four certified tower cranes in Washington state⁸. A breakdown statistics by crane owners indicated that only four of them were certified self-erecting tower cranes. The population of this type of cranes is likely still very small even including those that have not yet certified with the department. On the survey sent to employers, Question 4d through 4f asked respondents how much the costs would be each year if the proposed increased requirements for the use of self-erecting tower cranes were adopted. Only nine respondents said they use self-erecting tower cranes to perform construction work ("YES" to question 4a), among which there was only one small business. Therefore, the department did not think it would make much sense to compare the unit cost for businesses with different size based solely on survey data and decided not to do so.

     3. ACTIONS TAKEN TO REDUCE THE IMPACT OF THE PROPOSED RULES ON SMALL BUSINESS

     The above analysis indicates that small businesses are likely to bear a moderately disproportionate share of regulatory burden from the proposed rule. The law requires L&I to mitigate the cost for small business if it is legal and feasible to do so. In response to this requirement, L&I believes the following rules and practices will help to reduce the disproportionate impact of the proposed crane rule on small businesses.

     3.1 Reduce fines for small businesses:

     RCW 49.17.180(7) requires the department give consideration in the penalty assessment to factors including the size of the employer's business. Table 5 in the section of WAC 296-900-14015 spells out the specific process for penalty adjustments including employment size. Based on these standards, employers with twenty-five or fewer employees can request up to a sixty percent reduction in penalties issued against them.

     3.2 Enhance training and education opportunities for small businesses:

     The department has made a concerted effort to focus its training and education campaign on small businesses. This includes providing employers with materials that will help develop their crane safety plan, free training courses, train-the-trainer meetings and other related services.

     3.3 Prioritize consultation services for small businesses:

     The department has developed a variety of on-site and off-site consultation services primarily for smaller employers and has prioritized establishments by size when receiving requests for these services. For example, the highest scheduled priority of consultation services will be given to employers who employ less than twenty-five employees at the worksite. Most of these services are provided at no cost to the employer through state and federal funds. These services can include, but are not limited to, opening and closing conferences, a walk-through of employer worksites, identification of hazards, correction assistance, follow-up visits to verify correction of serious hazards, assistance in the development or improvement of the employer's occupational safety and health management system, technical assistance by telephone or letter and client visits to a department office. No penalties will be proposed or citations issued for any safety and health problems identified by the consultants. Hence, these consultation services greatly benefit small businesses in establishing and maintaining a safe and healthful workplace.

     3.4 Exempt recordkeeping and reporting requirements for small businesses:

     According to WAC 296-27-00103, establishments with ten or fewer employees are not required to keep injury or illness records. Based on the survey results, about one-quarter of the total affected businesses would fall into this category, and therefore are exempt from this record-keeping requirement.

     4. SMALL BUSINESS INVOLVEMENT IN THE RULE-MAKING PROCESS

     The department has made a considerable effort to involve small businesses and their representatives at various points in the rule-making process. These efforts include:

     (1) Since August 12, 2008, the department has held twenty stakeholder meetings in Tumwater and Tukwila to hear from the business community, including many small businesses. There was also a stakeholder comment period after each series of meetings. The representatives of small businesses, along with all the other attendees, have made a significant contribution to the development of the new crane rule.

     (2) Representatives of many business and trade associations such as Associated General Contractors (AGC) of Washington, Independent Business Association (IBA), Associated Builders and Contractors of Western Washington (ABC), and International Brotherhood of Electrical Workers (IBEW) were invited and heavily involved in the entire rule-making process. Many members of these associations are small businesses and their involvement with this rule-making activity has been reflected by engagement of these associations and their representatives.

     (3) The department developed the draft rule in February 2011, with the consideration of all the comments and concerns from the interested stakeholders across the state, including the small business community.

     (4) The department has also scheduled three public hearings for these proposed provisions in Spokane, Seattle and Tumwater in late August 2011. These hearings are held for all the stakeholders, including small businesses, to provide their comments about the proposed rule and the preliminary economic analysis reports. The department will then make any necessary amendments to the rule and/or the supporting reports based on the comments collected from these hearings.

     5. INDUSTRIES LIKELY TO BE REQUIRED TO COMPLY WITH THE RULE

     All the industries included in the sampling frame for the cost survey are listed in Table A1 in the appendix of this report⁹. A vast proportion of these businesses are small businesses with fifty or fewer employees. The actual compliance cost varies among different businesses. In some cases, employers even indicated there was no cost for them because they have already been in compliance with the proposed requirements, or the union has provided the services for free to their workers.

     6. NUMBER OF JOBS CREATED OR LOST

     The department does not anticipate that a significant number of jobs would be created or lost as a result of compliance with these proposed crane rule changes. Normally these requirements are such that employers will be able to meet them using existing staff and without the need for new hires. Similarly, there is no solid reason to expect that employers would need to dismiss a significant number of employees as a result of the draft proposed rule changes. Nevertheless, there may be a possibility that employers would hire more workers as internal evaluators to assess and ensure the qualifications of riggers and signal persons, since this could be a more cost-effective option compared to the use of third-party evaluators for some employers. The department does not know the extent to which this proposed provision would impact employment in the construction industry.

     7. CONCLUSIONS

     As we have analyzed above, the proposed Phase 2 crane rule is likely to impose moderately disproportionate compliance costs on small businesses. The extent of the disproportion varies among different rule components and the majority of this cost differential can be attributed to the cost relating to the use of a qualified evaluator to assess and document the qualifications. The primary reason for this difference is that large businesses likely have their own evaluators available for use, which is the lower-cost option allowed by the proposed rule, while most small businesses do not have this internal resource and therefore have to rely on a third-party qualified evaluator. From the benefit perspective, current research findings indicate that small businesses usually suffer significantly higher rates of injuries and fatalities than large businesses (Kaskutas, et al., 2009; Mendeloff, 2006; Ringen, 1995; Marsh, 1994; Toscano and Windau, 1994). Therefore, small businesses may benefit more in terms of the reduction in injuries and deaths if the proposed rule is adopted.

     8. LIMITATIONS

     Due to time and resource constraints, there are some limitations in this analysis, which can be summarized into the following categories.

     8.1 Exclusion of construction activities in general industry:

     While we included the majority of affected businesses in our analysis, we did not take the cases in which cranes are used by general industry to perform construction work into our consideration. This would affect our estimates on the total costs and average costs associated with the proposed provisions, but the effect is supposed to be limited. The limitation of the resources available to the department and the urgency of adopting this rule prevented us from conducting a more extensive analysis that includes both construction industry and general industry.

     8.2 Nonresponse bias:

     Although the number of completed surveys is larger than needed to ensure statistical validity, the number of respondents who are related to each survey section varies and it is likely there is some nonresponse bias, especially for the survey questions with low response rate. That is, some employers may be more inclined not to respond than others. For example, it is almost always the case that those with strong opinions about the survey topic or with more interest in the outcome are more likely to respond. In this survey, small businesses have more serious nonresponse bias than relatively larger businesses. This is evident in that the proportion of small businesses out of total businesses that have completed the survey is much smaller than their proportion in the population of entire affected businesses.

     8.3 Inclination to overestimate costs:

     In a similar manner, respondents naturally have an incentive to inflate their cost estimates, which may undermine the quality of the cost data we gathered. This incentive stems from the discontent that prevails among construction businesses with the safety regulations, especially in tough economic times like those we are currently experiencing.

     8.4 Missing or infeasible data:

     A small number of respondents indicated that a certain question applied to them, but they didn't provide numerical values of the costs. A few of them simply did not answer the question when they were asked to estimate the costs. Others described the costs as "a lot," "huge," "don't know," etc. These missing or infeasible data reduced the total number of "quantitatively useable" surveys on which this analysis is based.

     10. APPENDIX

     This table excludes the affected businesses in general industry other than those from real estate and rental and leasing industry.

     ¹The department does not consider the requirements that are already addressed in OSHA's new crane rule or in most recent ASME/ANSI standards increased requirements. Therefore, these provisions are excluded from this analysis. In addition, the department does not include the proposed provisions that will only impose minimal or minor costs on the businesses.

     ²To control the survey cost, we only consider crane lessees that are in the construction industry. In reality, there may be some businesses in the general industry that would also use cranes to perform construction work.

     ³We use $24.73 as the average hourly wage for riggers. This value was derived from the average weekly wage for all construction workers released by Washington employment security department Quarterly Census of Employment and Wages, 3rd quarter report, 2010.

     ⁴The average training class cost from all these providers is $299 and we use this value as the fixed training fee.

     ⁵This cost is the sum of evaluation fee, half of total cost for exams and twenty percent of total training cost.

     ⁶We use five percent as the discount rate to annualize the costs.

     ⁷The average training class cost from all these providers is $275 and we use this value as the fixed training fee.

WAC 296-99-040   What practices must an employer follow for entry into grain storage structures?   This section applies to employee entry into all grain storage structures.

     (1) The employer must ensure that the practice of walking down grain is prohibited. "Walking down grain" means an employee walks on grain to make it flow within or out from a grain storage structure, or an employee is on moving grain.

     (2) The employer must ensure that during the entry and occupation of a storage structure the employee uses:

•	A body harness with a lifeline; or
•	A boatswain's chair that meets the requirements of ((Part J-2 of chapter 296-24 WAC whenever)) chapter 296-874 WAC, Scaffolds:

     (a) The employee is exposed to a fall hazard such as when entering from the top or above the level of the stored grain; or

     (b) The employee is exposed to an engulfment hazard such as when entering at the level of the stored grain, or while walking or standing on the grain. The lifeline must be rigged so that its position and length will prevent the employee from sinking below waist level.

     (3) The employer must ensure that during the occupation of storage structures, including walking or standing on grain, employees are protected from hazards related to:

•	Mechanical;
•	Electrical;
•	Hydraulic; and
•	Pneumatic equipment.

By using safeguards, lockout-tagout, or other equally effective means. All provisions for the control of hazardous energy (lockout/tagout) from chapter 296-803 WAC apply to this chapter.

     (4) The employer must ensure that employees are prohibited from entering any storage structure where a build-up of grain overhead (bridging) or on the sides could fall and bury them.

     (5) The employer must ensure, as minimum precautions, that employee entry and occupation of all grain storage structures including flat storage structures is done according to all applicable requirements of chapter 296-809 WAC, Confined spaces, when the storage structure:

•	Has limited or restricted means of entry and exit; and
•	Is not designed for continuous employee occupancy.

     (6) The employer may allow an employee to perform confined space entry work in grain storage structures without a permit if the employer's representative personally monitors the work to prevent employee exposure to illness or injury from atmospheric hazards during the entire operation.

For jibs with variable offset angles, tests at the maximum offset used and maximum extension of all boom sections. All major components are to be proof load tested to a minimum of one hundred percent, not to exceed one hundred ten percent of each component's charted structural capacity. Hoist line pull or rigging is not to be a limiting factor for structural proof load tests.

     (i) This test must be performed in accordance with this section and documented on the form or in the format approved by the department.

     (ii) A copy of this completed form and inspection worksheets must be sent to the department within ten working days upon completion of the inspection.

     (d))) Free rated load test ("on rubber"). Check the stability and operation of crane, carrier, wheels, tires, tracks, brakes, etc., under load by performing the following tests, when lifting without outriggers and/or traveling with the load are permitted at the activity for the type of crane being tested.

Note:

Ensure all free rated load tests "on rubber" lifting requirements established by the OEM are complied with. Attach taglines to the load to control oscillation. For cranes with outriggers, extend outriggers and maintain minimal clearance (three to four inches) above ground. Test personnel must stand clear of tires during load tests. This test is only required if the owner/lessee wants an "on rubber" certification. If the crane has "on rubber" capabilities and the owner does not desire this certification, the crane certifier must document it on the certification document.

     (i) Maximum free rated load. Hoist maximum free rated test load at minimum possible radius over the rear (or over the front as required by the OEM). Slowly boom down to the maximum radius for the load, with boom and load hoist pawls (dogs) engaged where applicable, complete (d)(i)(A) and (B) of this subsection.

     (A) Rotate through the appropriate working arc;

     (B) Travel a minimum of fifty feet with test load over the rear (or front as required by the OEM) with the boom parallel to the longitudinal axis of the crane carrier.

     (ii) Stability test. Repeat the step in (d)(i) of this subsection with a test load corresponding to the radii determined as follows: For telescoping boom cranes, test with the boom approximately halfway between fully retracted and fully extended but do not exceed OEM's boom length limitation for lifting on rubber. If no ratings are governed by stability, no stability test is required.

Note:

When lifting test loads, always lift the load well within the maximum radius and slowly boom down to a premeasured radius. Lift the test load only high enough to perform the required tests.

Figure 4. Pendant is in tension while connected to uppermost boom section, and no pins are to be removed.

Figure 5. Pendant is in tension, and pins between pendant attachment point and crane body (indicated by arrows) are not to be removed. Note that, because the cantilevered portion of the boom is not supported, only the bottom pins ahead of the pendant may be removed. See Figure 8.

     (c) None of the pins (top and bottom) on boom sections located between the uppermost boom section and the crane/derrick body are to be removed (partly or completely) when the boom is being supported by the uppermost boom section resting on the ground (or other support). See, for example, Figure 6.

Figure 6. Uppermost boom section is resting on ground, and no pins between uppermost boom section and crane body are to be removed.

     (d) None of the top pins on boom sections located on the cantilevered portion of the boom being removed (the portion being removed ahead of the pendant attachment points) are to be removed (partly or completely) until the cantilevered section to be removed is fully supported. See, for example, Figures 7 and 8.

Figure 7. Cantilevered portion of boom is not supported, and top pins therefore are not to be removed. Bottom pins (circled) may be removed.

Figure 8. Cantilevered portion of boom is supported, and top pins (circled) may therefore be removed.

     (e) Signals must be discernible or audible at all times. The crane operator must not respond unless signals are clearly understood.

     (6) During operations requiring signals, the ability to transmit signals between the operator and signal person must be maintained. If that ability is interrupted at any time, the operator must safely stop operations requiring signals until it is reestablished and a proper signal is given and understood.

     (7) If the operator becomes aware of a safety problem and needs to communicate with the signal person, the operator must safely stop operations. Operations must not resume until the operator and signal person agree that the problem has been resolved.

     (8) Only one person gives signals to a crane/derrick at a time, except in circumstances covered by subsection (9) of this section.

     (9) Anyone who becomes aware of a safety problem must alert the operator or signal person by giving the stop or emergency stop signal. The operator must obey a stop (or emergency stop) signal, irrespective of who gives it.

     (10) All directions given to the operator by the signal person must be given from the operator's direction perspective.

     (A) Use a boom angle indicator.

     (B) Clearly mark the boom hoist rope (so that it can easily be seen by the operator) at a point that will give the operator sufficient time to stop the hoist to keep the boom within the minimum allowable radius. In addition, install mirrors or remote video cameras and displays if necessary for the operator to see the mark.

     (C) Clearly mark the boom hoist rope (so that it can easily be seen by a spotter) at a point that will give the spotter sufficient time to signal the operator and have the operator stop the hoist to keep the boom within the minimum allowable radius.

     (ii) If the crane was manufactured on or before December 16, 1969, and is not equipped with a boom hoist limiting device, at least one of the measures in (b)(i)(A) through (C) of this subsection must be used.

     (c) Luffing jib limiting device. Cranes with a luffing jib must have a luffing jib limiting device. Temporary alternative measures are the same as in (b)(i) of this subsection, except to limit the movement of the luffing jib rather than the boom hoist.

     (i) Telescopic boom cranes manufactured after February 28, 1992, must be equipped with a device which automatically prevents damage from contact between the load block, overhaul ball, or similar component, and the boom tip (or fixed upper block or similar component). The device(s) must prevent such damage at all points where two-blocking could occur.

     (A) Temporary alternative measures: Clearly mark the hoist rope (so that it can easily be seen by the operator) at a point that will give the operator sufficient time to stop the hoist to prevent two-blocking; and

     (B) Use a spotter when extending the boom.

     (ii) Lattice boom cranes.

     (A) Lattice boom cranes manufactured after February 28, 1992, must be equipped with a device that either automatically prevents damage and load failure from contact between the load block, overhaul ball, or similar component, and the boom tip (or fixed upper block or similar component), or warns the operator in time for the operator to prevent two-blocking. The device(s) must prevent such damage/failure or provide adequate warning for all points where two-blocking could occur.

     (C) Temporary alternative measures: Clearly mark the hoist rope (so that it can easily be seen by the operator) at a point that will give the operator sufficient time to stop the hoist to prevent two-blocking, or use a spotter.

     (iii) Articulating cranes manufactured after December 31, 1999, that are equipped with a load hoist must be equipped with a device that automatically prevents damage from contact between the load block, overhaul ball, or similar component, and the boom tip (or fixed upper block or similar component). The device must prevent such damage at all points where two-blocking could occur. Temporary alternative measures: When two-blocking could only occur with movement of the load hoist, clearly mark the hoist rope (so that it can easily be seen by the operator) at a point that will give the operator sufficient time to stop the hoist to prevent two-blocking, or use a spotter. When two-blocking could occur without movement of the load hoist, clearly mark the hoist rope (so that it can easily be seen by the operator) at a point that will give the operator sufficient time to stop the hoist to prevent two-blocking, and use a spotter when extending the boom.

     (e) Boom angle or radius indicator (except for derricks with base mounted drum hoists). The crane must have a boom angle or radius indicator readable from the operator's station. Temporary alternative measures: Radii or boom angle must be determined by measuring the radii or boom angle with a measuring device.
