OSHA has set maximum limits of levels of airborne asbestos dust to which workers may be exposed. Since most automotive friction materials normally contain a sizable amount of asbestos, it is important that people who handle brake linings and clutch facings uncrstand the nature of the problem and know the recautions to be taken. when exposure to asbestos dust may be at its highest. This increases the difficulty in com plying with the OSHA standards. In addition to the approved respirator, mere must De local exhaust ventilation such that worker ex posures are maintained below the OSHA asbestos standards If there is any question as to the efficiency of asbestos dust removal by the machine, the manufacturer should oe con tacted 13 CJ. . Areas where brake work is done should be set aside if possible, and entrances should be posted with an asbestos exposure sign as follows: Asbestos Dust Hazard Avoid Breathing Dust Wear Assigned Protective Equipment Do Not !.' Area U nless Your Work Requires It Breathing Asbestos Dust May B9 Hazardous To Your Health 2 The amount nf asbestos in the dust from brake lining wear is normally at an extremely low level because of chemical breakdown during use, and if machining of friction m aterial dues nui take p'ace, Simple procedures will minimize exposure. During brake servicing, the mechanic should wear a respirator approves by NIO SH for asbestos dust. It should be worn during all procedures starting with the removal of wheels and in cluding reassembly. 3. When removing worn friction materials, rem ove the accu m ulated dust in the asscmb!ics *vith cn industrial vacuum cleaner equipped with a high efficiency filter system If such equipment is not available, dust can be removed with a damp cloth Do not use com pressed air or dry brushing for cleaning unless the assembly is enclosed and properly ex hausted. 4.

Industrial vacuum cleaner bags containing asbestos dust and cloths used for wiping brake assemblies should be sealed in plastic bags and labeled with the following warning label printed in letters of sufficient size and contrast to be readily visible and legible.

During removal qf vacuum bags, an approved respirator, as described in (2) above should be worn 6. Good h o usekeeping is essentia: in a workplace where asbestos containing materials are handled, industrial vacuum cleaners equipped vvitn mltiple 5ta^e niyn efficiency filters should be used for removing accumulations of asbestos dust and waste Never use compressed air or dry sweeping for cleaning. Water or otner oust suppressants should be applied if brooms a uic. 7. Good personal hygiene piCiiS ie iti'ipGi tant in minimizing asbestos dust exposure. Do not smoke. Wash before eating. Shower after work. Change to work clothes upon arrival at work and change from work rinthe* at con clusion of work. Work clothing should cot he taken home. Laundering of asbestos con taminated clothing shall be done so as :n p re vent release of airborne asbestos fibers in ex cess of the exposure limits. /t^AAUIIITIlA u n*|i .
