In response to a request from a representative of the employees at Drive Train Industries, Inc. (SIC-3714), Casper, Wyoming, a possible asbestos (1332214) hazard was investigated at the facility. An evaluation was also made of stoddard-solvent (8052413), welding fumes, iron-oxide (1309371), lead (7439921), crystalline silica (7631869), and noise exposures. This facility was involved in the rebuilding and repairing of various truck parts including brakes, clutches, drivelines, transmissions, and other mechanical parts. Many of the brakes and clutches as well as parts of other products, were refurbished and relined with some asbestos material. Three personal air samples and three area samples were collected for asbestos which produced values ranging from less than 0.1 to 340mg/m3, with the average value being 64mg/m3. Iron-oxide concentrations at the welding station ranged from 0.2 to 12mg/m3. The average lead concentration was 0.03mg/m3. No silica was detected. One worker was overexposed to noise with an 8 hour average of 94.3 decibels-A. The author concludes that a health hazard does exist from excessive noise exposures and elevated iron- oxide levels. The author recommends that adequate hearing protectors should be provided by the management.
