Abstract Personal and general area air samples were collected and analyzed for both Time Weighted Average (TWA) and peak asbestos (1332214) fiber concentrations to which brake mechanics would likely be exposed while on the job. Of the six facilities examined, two were automotive brake service shops, three were municipal garages, and one was a private fleet service garage. Asbestos fiber content and size were determined from bulk samples. Of the 13 TWA's determined for mechanics, the NIOSH recommended limits of 0.1 fibers/cubic centimeter (fibers/cc) greater than 5 micrometers (microm) in length was exceeded in 8. However, even these 8 were within the current OSHA standards. With the exception of vacuum cleaning, all cleaning methods produced fiber levels near the NIOSH recommended ceiling, which is 0.5 fibers/cc. The OSHA ceiling limit, 10 fibers/cc, was exceeded twice when compressed air cleaning was used. The authors made recommendations.
