An industrial hygiene survey was conducted at Drive Train Industries, Incorporated (SIC-3714) in Grand Junction, Colorado on November 30, 1982. The request came from an employee representative to determine if there was a health hazard from asbestos (1332214) exposure during the reconditioning of truck brakes and clutches. Airborne concentrations of asbestos, sodium-hydroxide (1310732), total welding fumes, nickel (7440020), manganese (7439965), copper (7440508), and noise levels were determined. Of two personal and three area samples taken for asbestos, one was above the NIOSH criteria of 0.10 fibers per cubic centimeter greater than 5 microns in length. Samples of all other chemicals and measures of noise levels were below NIOSH criteria values. An exhaust system was developed to remove the major source of asbestos exposure during the tear down process by adapting a vacuum exhaust hose to the deriveting machine. The system was very effective in exhausting the dust generated by the operation. The authors conclude that a potential health hazard existed from asbestos exposure to one employee. The exhaust ventilation program should be maintained and continued to further reduce overall asbestos exposures.
