OSHA Asbestos Alert Background: Brake and Clutch Repair Work
Read more here about the OSHA recommendations when performing automobile repair and working with asbestos-containing brake and clutch parts.
Many brakes and clutches used in new and recent model automobiles do not contain asbestos. However, it has not been totally eliminated.
Some reports have indicated that many mechanics and employees in the automotive repair shops as well as do-it-yourselfers are unaware that asbestos may be present in both old and replacement brakes and clutches.
OSHA’s asbestos standard requires the use of controls and safe work practices when employees work with brake shoes and clutches that contain asbestos.These requirements are detailed in 29 CFR 1910.1001 of the standard - Work Practices and Engineering Controls for Automotive Brake and Clutch Inspection, Disassembly, Repair and Assembly (http://www.osha.gov/SLTC/asbestos/index.html).
The requirements also are discussed in the Federal Register at 59 FR 40964, 40985-87 (August 10, 1994) and 60 FR 33983 (June 29, 1995), as well as in OSHA Directive CPL 2-2.63 (revised).
