Environmental and breathing zone samples were analyzed for total dust, benzene soluble coal tar fractions, and polynuclear aromatic hydrocarbons (PAHs) during roof removal operations (SIC-1761) at the Fisher Body facility, Hamilton, Ohio, in December, 1983. The evaluation was requested by the United Union of Roofers, Waterproofers, and Allied Workers. All 13 employees involved in the roof removal were interviewed and given limited physical examinations. Total dust concentrations ranged from 2.1 to 13.1 milligrams per cubic meter (mg/m3). The OSHA standard is 15mg/m3. Benzene soluble coal tar fractions ranged from 0.6 to 5.3mg/m3. The OSHA standard for cyclohexane soluble fractions (assumed comparable with benzene soluble fractions) is 0.1mg/m3. Geometric mean PAH concentrations ranged from 12.8 to 48.1 micrograms/m3. No standards for PAHs are given. Acute eye irritation symptoms such as burning, redness, and tearing and chronic eye and skin irritation were the most frequent symptoms found. The prevalence of chronic skin lesions could not be determined due to cold weather and the use of heavy clothing. The authors conclude that the workers involved in roof removal operations are overexposed to coal tar pitch dust containing PAHs. Recommendations include wetting the roof surface and wearing protective equipment and clothing.
