Industrial Hygiene Technical Bulletin No- 83-4 Date: 1983 November 16 RE: EMERGENCY TEMPORARY STANDARD FOR ASBESTOS - 0.5 FIBERS/CC OSHA has enacted an emergency temporary standard (ETS) for asbestos effective 1983 November 4, with a final rule to followwithin six months. Attached please find a copy of the amend ment to the standard. Alcoa set an internal limit of 0.5 fibers/cc in June of this year, as well as instituting training requirements, medical surveillance criteria, etc. (refer to IH Technical Bulletin 83-3). Therefore, the ETS should have minimal impact on our operations. Please note, however, that more stringent respirator selection requirements exist under the ETS and will most likely appear also in the revised final rule. Reusable or single use air purifying respirators are acceptable for concentrations not to exceed 5 fibers/cc. Full facepiece air purifying respirators or powered air purifying respirators are acceptable for concen trations up to 50 fibers/cc. Posting of warning signs and training of all employees exposed above the PEL of 0.5 fibers/cc are required by OSHA through the ETS. Please contact me at extension 2597 if you need assistance acquiring training material or appropriate warning signs. JOAN E. SANDER JES:bep Attachment cc: H. D. Belk, M.D., Pittsburgh - 6 G. J.

No. 21S / Friday. November 4, 1983 / Rule* and Regulation* 51139 respirators, and to assure that all such employees participate in the program and are informed of specified categories of information. OSHA considers this provision to be "necessary" within the meaning of section 6(c) of the Act to reduce the grave danger faced by asbestos exposed employees. The absence of a training program requirement in the asbestos standard has been pointed out as one of the serious deficiencies of the currant standard. OSHA believes that participation in an adequate training program is essential for the protection of employees because most protective provisions enlist the employee as an active participant. For example, many employees handling asbestos depend on effective work practices. Without training in applying these work practices, employee protection would be inadequate. Where the employee plays a more passive role in his protection such as where engineering controls are relied on. training is also essential, because the employee must know the sources of workplace asbestos contamination, and the health hazards of asbestos exposure, in order to assess his own exposure situation and to help recognize when engineering controls are not operating properly. Certainly where housekeeping plays an important role in control instruction about housekeeping . . methods, for example, frequent vacuuming, is essential. Perhaps most imporianly. where employee protection depends upon respirator use, OSHA's experience shows that training employees in the use, fitting and limitations of respirators is critical to the effectiveness of respirator protection. Accordingly this requirement applies where airborne concentrations are reasonably expected to exceed 0.5 f/ cc, even if employees use respirators to reduce breathing zone concentrations and thereby comply with the ETS. As set forth in paragraph (k)(4) the employer must inform the employee of the health effects of asbestos exposure; the relationship between asbestos and smoking in producing lung cancer, the operations exposing employees to asbestos fibers and necessary protective steps to minimize exposure; the purpose, proper use. fitting instructions and limitations of respirators, and the contents of all the provisions of the Asbestos' Standard at 1910.1001. 5. Paragraph (k)(5) Respiratory protection during the ETS. The ETS adds a new paragraph (k)(5) which includes a table which ties respirator selection to the 0.5 f/cc PEL Under the ETS, the concentration cut-offs for various kinds of respirators are multiples of the reduced PEL of 03 f/cc, rather than multiples of the previous 2 f/ cc permissible limit. For example, approved air purifying respirators may be used only where asbestos concentrations are not expected to exceed 5 f/cc (10 x the PEL). Before the ETS, because the PEL was 2 f/cc. such respirators could be used where asbestos concentrations would not have exceeded 20 f/cc (10 x the PEL of 2 f/cc). Similarly, powered air purifying respirators may be used where asbestos concentrations do not exceed 100 times the PEL which at the new level of 03 f/ cc is 50 f/cc. Previously, employers could have used such respirators at concentrations up to 200 f/cc. It is likely that the main impact of the reduced PEL on respirator choice will be in operations and industries where exposure levels are between 5 f/cc and 20 f/cc. Formerly, employees exposed in this range could use half-mask air purifying'respirators; now they must be protected by a powered air purifying respirator or a full facepiece respirator, or they may use a supplied air respirator. 6. Paragraph (k)(6). Warning signs during the ETS. The ETS require* that legible signs warning of the health hazards of asbestos be displayed at locations where airborne concentrations of asbestos fibers exceed the reduced exposure limit of 0.5 f/cc. No specific legend is required signs for newly posted during the ETS. OSHA wishes to make as practicable as possible the rapid posting of signs, especially in workplaces where there has been previous non-compliance and in areas where asbestos concentrations were formerly below the 2.0 f/cc PEL XL Public Partidpatioa Interested persons are invited to submit written data, views and arguments with respect to the revisions to the esbestos standard made by the ETS.
