Employee exposure to lead (7439921) and asbestos (1332214) at Raybestos Friction Materials Company (SIC-3714), Crawfordsville, Indiana was investigated. The study was confidentially requested and was performed on March 11 to 13, 1981. The facility employed about 430 hourly workers including 93 in the brake block area. Personal airborne sampling was conducted to evaluate exposure to formaldehyde (50000), asbestos, lead, tin (7440315), barium (7440393), and zinc (7440666). Medical interviews were performed. Formaldehyde concentrations peaked at 0.82 parts per million. NIOSH considers formaldehyde to be a potential occupational carcinogen and recommends that exposures be maintained at the lowest feasible concentration. Four airborne samples of asbestos were above the NIOSH recommended standard of 0.1 fiber greater than 5.0 microns per cubic centimeter. Medical interviews did not reveal findings that could be attributed to asbestos, lead, or other heavy metal exposure. The authors conclude that a health hazard did exist in the brake block area since airborne concentrations of personal samples of formaldehyde and asbestos exceeded NIOSH criteria. Recommendations are made for increased environmental monitoring of airborne contaminants and for modification of employee work practices.
