Potential health hazards from asbestos (1332214) during the manufacture of an asphalt and asbestos roofing compound were investigated. The study was requested by the owner and management of Grundy Industries (SIC-2952), Joliet, Illinois and was performed on November 4 and 19, 1981. A total of seven employees were involved in the operation. Personal breathing samples revealed concentrations of 0.15, 0.32, and 0.73 fibers greater than 5 microns in length per cubic centimeter. All personal and area air samples exceeded the NIOSH 8 hour time weighted average recommended value of environmental survey revealed airborne concentrations of 0.55 and operation. The exhaust ventilation measurements operated at 20 percent of the recommended duct velocity. The design of the ventilation hood did not provide capture velocities sufficient to capture the asbestos fibers. The authors conclude that a health hazard did exist from exposure to asbestos. Recommendations for maintaining a clean work site and improving the local exhaust ventilation system are provided.
