Environmental and breathing zone samples were analyzed for asbestos (1332214) at Grundy Industries, Incorporated (SIC-2952), Joliet, Illinois in October and December, 1983, and February, 1984. The survey was requested by the owner and manager to evaluate employee exposures to asbestos during manufacture of a roofing compound. During the October, 1983 survey, an equipment breakdown at the asphalt mixing tank occurred. Breathing zone samples taken prior to or during the breakdown had asbestos concentrations of 0.21 to 2.2 fibers per cubic centimeter (f/cc). Breathing zone samples after repairs were completed were 0.25 to 1.0f/cc. An environmental sample contained 0.6f/cc. The OSHA standard for asbestos is 2.0f/cc. Samples from the December, 1983 survey were invalidated due to contamination of the filters. Breathing zone and environmental samples obtained in February, 1984 contained 0.16 to that a health hazard exists, since all samples exceeded the NIOSH recommendation of lowest feasible exposure. The higher concentrations observed in October, 1983 were probably due to the equipment breakdown. Recommendations include replacing asbestos with a less toxic substance if possible, using engineering control methods to control asbestos exposure, and establishing an effective respirator program.
