FILE NAME: Abex (ABX) DATE: 1985 DOC#: ABX236 DOCUMENT DESCRIPTION: Recommended Procedures for Reducing Asbestos Dust During Brake Servicing RECOMMENDED PROCEDURES FOR HEUUUUMU ASBESTOS DUST DURING BRAKE SERVICING when exposure to asbestos dust may be at its Because studies have indicated that exposure to excessive amounts of asbestos oust may be a potential health hazard. OSHA has set maximum highest. This increases the difficulty m com plying with the OSHA standards. In addition to the approved respirator, there must be 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 un local exhaust ventilation such that worker ex posures are maintained below the OSHA asbestos standards. If there .s any question as to the efficiency of asbestos dust removal by the machine, the manufacturer should De con derstand the nature of the problem and know the tacted. precautions to be taken. 5. Industrial vacuum cleaner bags containing t 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 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. Asbestos Dust Hazard Avoid Breathing Dust Wear Assigned Protective Equipment Do Not R e - : if- Area Unless Your Work Requires It Caution Contains Asbestos Fibers Avoid Creating Dust Breathing Asbestos Duct V.sy Serious Bodily Harm Breathing Asbestos Dust May Be Hazardous To Your Heaith All asbestos waste should oe disposed of m accordance with OSHA and EPA asbestos 2 The amount of asbestos in the dust from brake lining wear is normally at an extremely low level because of chemical breakdown regulations. During removal of vacuum bags. an approved respirator, as described in (2) above should be worn during use. and if machining of friction m aieriai dues nol take p'ace, Simple procedures will minimize exposure. During brake servicing, the mechanic should wear a 3pprcvec by NIOSH for asbestos dust. It'should be worn during all procedures starting with the removal of wheels and in cluding reassembly. 6. Good housekeeping is essentia! in a workplace where asbestos containing materials are handled. Industrial vacuum cleaners equipped with multiple atayc " l y 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 3.
