Procedures for Reducing Asbestos Dust During Brake Servicing." An excerpt of this pamphlet is reprinted below: RECOMMENDED PROCEDURES FOR REDUCING ASBESTOS DUST DURING BRAKE SERVICING Because studies have indicated that exposure to excessive amounts of asbestos dust may be a potential health hazard, OSHA has set maximum levels 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 understand the nature of the problem and know the precautions to be taken. 1) 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 REMAIN IN AREA UNLESS YOUR WORK REQUIRES IT BREATHING ASBESTOS DUST MAY BE HAZARDOUS TO YOUR HEALTH The amount of asbestos in the dust brake lining wear is normally at an extremely low level because ofchemical breakdown during use, and if machining of friction material does not take place, simple procedures will minimize exposure. 2) During brake servicing, the mechanic should wear a respirator approved by NIOSH for asbestos dust. It should be worn during ail procedures starting with the removal of wheels and including reassembly. 3) When removing worn friction materials, remove the accumulated dust in the assemblies with an industrial vacuum cleaner equipped with a high efficiency . filter system. Ifsuch equipment is not available, dust can be removed with a damp cloth. Do not use compressed air or dry brushing for cleaning unless the assembly is enclosed and properly-exhausted. 4) Whenever possible, purchase friction materials pre-ground and ready for installation. If matching is necessary, the precautions which must be taken are ofextreme importance. This is the operation in brake service when exposure to asbestos dust may be at its highest. This increases the difficulty in complying with the OSHA standards. In addition to the approved respirator, there must be local exhaust ventilation such that worker exposures 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 be contacted. 5) industrial vacuum cleaner bags containing asbestos dust and cloths used for 115
