SM-3 2 (REV. 5*78) Shell Oil Company Interoffice Memorandum NOVEMBER 21, 1983 FROM: J. L. RIVARD TO: D. P. ATWOOD F. A. ELY J. J. PICKELL J. S. SZYMANOWSKI SUBJECT: OSHA EMERGENCY TEMPORARY STANDARD FOR ASBESTOS On November 4, 1983, OSHA published an Emergency Temporary Standard (ETS) for asbestos, effective immediately. Although the Asbestos Information Association has filed suit, the ETS remains in effect. Additionally, OSHA has indicated their intent to step up asbestos enforcement activity. In this regard, EPA will be advising OSHA of planned asbestos-demolition jobs, thereby increasing the probability of a related OSHA inspection. The ETS applies to general industry, construction, and maritime. States with OSHA-approved plans are expected to adopt a comparable standard within 30 days. The ETS also constitutes a Notice of Proposed Rulemaking for the permanent standard. Under the Act, a permanent standard must be published within six months of an ETS. Meanwhile, all provisions of the existing asbestos standard 1910.1001 continue to apply, except to the extent modified by the ETS. While OSHA calls for comments on this ETS, our intent is not to partici pate in an ETS debate or in the subsequent rulemaking for the permanent standard. Rather, Shell's efforts should be directed towards compliance. The following may help ensure a rational approach to compliance. ETS REQUIREMENTS (COPY ATTACHED) The ETS establishes a permissible exposure level (PEL) of 0.5 fibers per cc of air for an 8-hour time weighted average (TWA), a four-fold reduc tion from the current PEL of 2.0 fibers per cc. The ETS permits any combination of engineering controls, work practices, and personal protective equipment to achieve compliance with the new PEL. However, the requirement of the existing standard 1910.1001(c) to utilize feasible engineering controls and work practices to reduce exposures to the 2.0 fibers/cc level remains in effect. The ETS requires that within 30 days (i.e., by December 4, 1983), the employer shall institute a training program for all employees exposed "in excess of 0.5 fibers/cc, without regard to the use of respirators. ..." (emphasis added). CB8332508A LAM 001047 DPMC-16746 2 The ETS further requires selection of specific types of respiratory protection and the use of warning signs at each location where exposure may exceed the new TWA PEL. The ETS makes no changes in medical surveillance. EXISTING STANDARD (COPY ATTACHED) The existing standard 1910.1001 remains in effect, except to the extent modified by the ETS. The remaining provisions of the existing standard include: A ceiling PEL of 10 fibers/cc Methods of compliance (1) Engineering controls (to achieve compliance with the old PEL of 2.0 fibers/cc) (2) Work practices, including wet work methods Personal protective equipment (1) Respiratory protection program (2) Special clothing, change rooms, and laundering Caution signs and labels (Note - The ETS relieves some of the specificity pertaining to signs.) 0 Housekeeping Recordkeeping Medical surveillance (Note that the existing standard has no specific training requirements. However, many locations may already have an asbestos training program.) COMPLIANCE PLANNING For workplaces meeting the new PEL Functions and locations with asbestos compliance programs in place and with monitoring data confirming that exposures do not exceed the new PEL are not required to take any additional action to comply with the ETS, other than to ensure that respirator selection (when needed) ,is in accord with the new requirements. CB8332508B LAM 001048 DPMC-16747 3 Even so, in view of the increased OSHA enforcement activity, it may be useful for such functions and locations to review their asbestos compliance program and document that past exposures have not ex ceeded the new PEL. Further, it may be prudent to inform affected employees of the ETS and provide refresher training. In this regard, the Shell Training Resource Program H-140, Asbestos In The Workplace provides an excellent training tool, when coupled with an advisory regarding the new PEL. In addition, review of the Shell medical surveillance program for asbestos should be considered. Guidance regarding that program is contained in your Health and Safety Compliance Review Manual. For workplaces not meeting the new PEL Functions or locations with monitoring data showing exposure above the new PEL will be required to implement the training provisions of the ETS. Additionally, those without well-documented asbestos compliance programs should consider strengthening their overall program. A suggested plan follows. (1) Inform affected employees of the existence and provisions of the new ETS. A sample notice is attached. (2) Initiate a training program for affected employees. Target earliest training for those who may routinely be exposed to asbestos (e.g., insulators, brake mechanics, carpenters working with asbestos-transite). Ensure training of any employees assigned to particular asbestos-demolition jobs, before such jobs are performed. The Asbestos Training Resource Program can be used as one element of this training. (3) Review the medical examination program to ensure that the local program is up-to-date (see your Health and Safety Compliance Review Manual). For all workplaces Notify contractors of the new ETS and Shell Oil Company's expecta tion that their programs will comply. Questions regarding the ETS, suggested compliance planning, or available monitoring data can be referred to J. L. Rivard or C. F. Phillips, as appropriate. Questions pertaining to medical surveillance should be directed to Corporate Medical.

This new PEL is in effect now in all general industry, construction, and maritime activities. States with OSHA plans are expected to adopt a comparable standard within 30 days. Asbestos is a health hazard when taken into the system in excessive amounts. The asbestos fibers are associated with a variety of diseases, including (1) Asbestosis - a non-malignant scarring of the lungs; (2) Bronchogenic Carcinoma - a malignancy (cancer) of the lung; (3) Meso thelioma - a malignancy of the lining of the chest cavity; and (4) cancer of the stomach, colon, and rectum. These diseases develop slowly, and usually do not become evident until many years after initial exposure. Asbestos fibers can enter the system via the breathing process or via eating or drinking. When dry, the small asbestos fibers are easily "airborne" and can contaminate the work area. Smoking drastically increases the chances of cancer occurring with asbestos exposure. Asbestos is a mineral silicate occurring naturally as a variously colored fiber. It is non-combustible, non-conducting, and resistant to deteriora tion and chemical attack. Because of these properties, it has found widespread use in thermal insulation, asbestos floor tile, roofing and transite materials, gaskets, coatings, plastics, and brake linings. Because of its fibrous nature, it can be woven into cloth, or used to add strength to other materials. Asbestos is most frequently encountered within [name of location] as insulation on pipes and structures. While purchase of new insulation containing asbestos has been discontinued, asbestos insulation may be encountered in older facilities for years to come. Whenever possible, asbestos materials should be handled in a wet state to prevent or minimize the formation of airborne asbestos fibers. Work areas shall be wet-cleaned; dry sweeping and blowing create the hazard of airborne asbestos fibers. Engineering controls, such as isolation, enclosure, exhaust ventilation, and dust collection are used to control asbestos exposures. Respiratory protection is also used to protect employees. The approved respiratory devices for asbestos are specified in the new OSHA standard. Warning signs must be posted when asbestos exposure exceeds the PEL. If you are working at a task where exposure to airborne asbestos fibers is likely, coveralls shall be worn. Laundering service will be provided or disposable coveralls used. CB8332508B lam 001054 DPMC-16753 OSHA EMERGENCY TEMPORARY STANDARD FOR ASBESTOS 2 Identifying labels shall be applied to waste asbestos or asbestoscontaining debris if there is a likelihood that airborne concentrations of asbestos fibers could result. This label shall state, "CAUTIONCONTAINS ASBESTOS FIBERS-AVOID CREATING DUST-BREATHING ASBESTOS MAY CAUSE SERIOUS BODILY HARM." All asbestos materials will be disposed of via landfill at an approved location, in accord with EPA requirements. CB8332508B LAM 001055 DPMC-16754
