Safety H&ealth Bulletin ooo i\pc No. 15 October 30, 1973 ASBESTOS HANDLING GUIDELINES NATIONAL PAINT & COATINGS ASSOCIATION 1500 Rhode Island Avenue, N.W. Washington, D C. 20005 Telephone 203 462*5272 ROUTE TO: Department Finsnc* Administration Stitt T#c/inicmt Production Executive Synopsis This bulletin was developed by the NPCA Occupational Health Task Force to assist in the compliance with Section 1910.93a "Asbestos" of the regulations implementing the Occupa tional Safety and Health Act. It includes the background and limits imposed by the regulation as well as methods for compliance. These methods, however, are offered as guidelines and each manufacturer should examine carefully his own specific requirements. ACTION REQUIRED BY YOU - Forward the bulletin to the person or persons responsible for'your safety and health operations. ACTION TAKEN BY NPCA - The NPCA Occupational Health Task Force will continue to monitor OSHA actions on asbestos, and comment when the paint and coatings industry is affected. OPERATIONS AFFECTED IN YOUR COMPANY - Manufacturing, Safety and Health STAFF CONTACT AT NPCA - Richard W. Murry, Assistant Technical Director 411084 1670 I 2 The Department of Labor under authority of the Occupational Safety and Health Act, promulgated standards and regulations governing the use and handling of Asbestos. The Regulation appears in Part 1910 of the Occupational Safety and Health Standards, Subpart G, Occupational Health and Environmental Control Section 1910.93a, a copy of which is included in this bulletin. It is the responsibility of each employer to become familiar with the standard and devise a compliance plan to suit the needs of his organization, and is vital that specific accountabilities be assigned to competent staff members. If the provisions of the standard are not well understood, then the service of a reliable industrial hygiene consultant should be sought. DEFINITION Section 1910.93a presently defines Asbestos to include chrysotile, amosite, crocidolite, tremolite, anthophyllite and actinolite. (Note that talc is possibly covered under this regulation if fibrous, see Table G-3 of the attached regulations.) Asbestos fibers are fibers longer than five micrometers. HAZARDS Asbestosis and lung cancer have long been associated with exposure to Asbestos. Historically, the incidence of these diseases has been significantly higher among asbestos workers than among the general population. It has also been demonstrated that smokers are much more likely to develop Asbestosis than non-smokers. Principal sources of employee exposure in the coatings manufacturing industry will result from handling Asbestos. Dumping or changing Asbestos into mixing or thinning tanks or ball mills provides the greatest exposure. Employees performing maintenance work such as installing, repairing, or removing of Asbestos insulating materials, transite piping or siding and roofing could also be exposed to airborne Asbestos. . EXPOSURE LIMITS As of July 7, 1972, Asbestos dust concentrations in air shall not exceed an eight-hour time-weight average of five fibers longer than five microns per cubic centimeter of air. At no time may the concentration exceed a ceiling of ten fibers longer than five microns per cubic centimeter. The eight-hour time-weighted average is the average concentration occurring over a period of eight continuous hours. After July I, 1976, the time-weighted average is reduced from five to two fibers longer than five microns per cubic centimeter. 411084 1671 3 CONTROL OF ASBESTOS DUSTS Engineering controls, such as, but not limited to, isolation, enclosure, local exhaust ventilation and dust collection shall be used to meet the permissible exposure limits. Use of respiratory protective equipment may be employed only: (a) During time necessary to install engineering controls (b) In situations where controls are technically not feasible or insufficient to meet exposure limits (c) In emergencies When using respiratory equipment the employer should document the use and any studies and investigations undertaken. Failure to have this information on file may result in OSHA's refusal to accept the use of protective equipment. Some references for information on industrial exhaust systems are: "Industrial Ventilation - A Manual of Recommended Practices" ANSI Z-9.2 "Fundamentals Governing the Design and Operation of Local Exhaust Systems" RESPIRATORY EQUIPMENT 1. Mechanical-filter type respirators (Bureau of Mines approved) are required when the time - weighted average or ceiling concentrations are reasonably expected to exceed no more than ten times the limits. 2. Powered-filter type respirators are required when the time-weighted average or ceiling concentrations are reasonably expected to exceed 10 times, but not 100 times, the limits. 3. Atmosphere-supplying respirators (type "C" supplied air or self contained) are required when the time-weighted average or ceiling concentrations are reasonably expected to exceed 100 times the limits. Spraying of Asbestos or demolition or removal of Asbestos insulation require the use of atmosphere-supplied respirators. 4. The Respirator program shall be established in accordance with the requirements of "ANSI Z88.2-1969, Practice for Respiratory Protection." 5. Each employee who may use a respirator shall be instructed in its use and in testing it for proper fit. 411084 1672 5 CAUTION SIGNS AND LABELS Caution signs shall be posted at all locations where airborne concentrations of Asbestos fibers may be in excess of the established limits. See Fig. I Caution labels shall be affixed to all containers of raw materials, scrap, waste, other products containing Asbestos and Asbestos contaminated clothing. See Fig. 2 !i Note: Caution labels are not required for products where the asbestos fibers have been modified by a bonding agent, coating, binder or any other material so that under reasonable use no airboume concentration in excess of the exposure limits will be released. EMPLOYEE NOTIFICATION AND RECORD KEEPING The employer shall notify, in writing, every employee found to have been exposed at any time to airborne concentrations of Asbestos fibers in excess of the exposure limits. The establishment of a training program to include work practices to minimize exposure vx>uld also be in order. ' Medical records of employee examinations must be maintained for 20 years. Records of personnel and environmental monitoring shall be maintained for three years. Records shall be made available upon request to representatives of OSHA and NIOSH. Medical records shall be made available, upon the request oflan employee or former employee, to his physician. 411084 1673 3 1/4 Yellow letters on black background Black letters on yellow background Letter sizes and styles to be at least as visible as that listed below: I" Sans Serif, Gothic, or Block -- 3/4" Sans Serif, Gothic, or Block -- 1/4" Gothic ' ..................
