Hazardous exposures during removal of an old coal-tar pitch roof were investigated on December 9 and 10, 1981 at Anchor Hocking Glass Company (SIC-1761) in Lancaster, Ohio. Evaluation was requested by United Union of Roofers, Waterproofers, and Allied workers for an unspecified number of workers. Sixteen personal area air samples were analyzed for polynuclear aromatic hydrocarbons and benzene solubles. Bulk samples were also analyzed. Workers were questioned about medical symptoms. Bulk tear off dust contained 7 percent cyclohexane solubles per milligram. Various polynuclear aromatic hydrocarbons and trace amounts of quartz (14808607) and asbestos (1332214) were identified. Exposures to the benzene soluble fraction and polynuclear aromatic hydrocarbons in dust ranged from cubic meter. Exposures to polynuclear aromatic hydrocarbons in hot asphalt ranged from 0.2 to 6.3 micrograms per cubic meter. The NIOSH standard for exposure to coal-tar products is 0.1 milligrams per cubic meter; and for asphalt fumes, 5.0 milligrams per cubic meter. Symptoms included dermal erythemia, photosensitivity, and conjunctivitis. The author concludes that hazardous coal-tar pitch dust exists, and a potential asbestos hazard is present. He recommends improved hygiene practices and use of safety equipment.
