'iv Nl6r.ll wants service establishments nlcrted to this danger because if. feels that the hazard is much more severe than 'normally believed and ' nay he joIn; unrecognized. NIOSII estimates thHt potent Ini exposuro . in this industry may be- reaching nearly 1,000,000 wotkers. . . Although it Is continuing research in this area. NTOSIl has recommended. * ` ^ the attached Interim procedures designed specifically to reduce usbestos 1 > exposure in automotive service areas. The recommended procedures are meant to supplement, not replace, the current ashestos standard admin- . . <: istored by the Occupational Safety and Health Administration (OSHA). The OSHA standard applies to all occupations where there is exposure to asbestos dust. Tho standard regulates permissible concentrations of asbestos fibers, methods of compliance, warning signs, monitoring, medical examinations and recordkeeping, if you do not have a copy of the current enforceable OSHA standard, APAA will he happy to supply you with one. ; ' After three years of enforcing its standard, OSHA is now considering ` / '._i more stringent measures. According tc OSHA, new evidence indicates 1 * that asbestos levels sought In the current standard are not low enough ..., to reduce potential health hazards in tho workplace. Originally in tent on reducing the number of cases of nsbestiosis (lung-scarring), .. ' OSHA now believes that asbestos is a human cancer-causing agent and , that anyone working in the vicinity of asbestos dust is in danger, j ;i- Asbestos can cause lung cancer at levels much below those that canj"' causo ssbestiosls. OSHA administrators have said that their enforcement activity this year .will focus heavily on toxic substances such as esbostos dust. MAR 000915 ( ) ;,-j R , ; iMjfrp.;... , .'.'Mf,.: J.f.Vi.
