| Abstract |
This study was conducted to assess historical asbestos exposures of mechanics performing clutch service on motor vehicles. Personal and area air samples were collected during the removal of asbestos-containing clutches from 15 manual transmissions obtained from salvage facilities by an experienced mechanic. Clutch plates and debris were analysed for asbestos using EPA and ISO published analytical methods. More than 100 personal and area air samples were collected and analyzed for asbestos fibres using NIOSH methods 7400 and 7402. A separate study involved a telephone survey of 16 automotive mechanics that began work prior to 1975. The incremental contribution of this task to mechanics' 8-hr time-weighted average (TWA) asbestos exposures was estimated to be 0.0016 fibres/cc, ranging from 3.75x10-5 fibres/cc to 0.03 fibres/cc. The mean value of 0.0016 fibres/cc is below background levels of asbestos that have been reported in garages during this time and below the current OSHA PEL of 0.1 fibres/cc. |
