Environmental and breathing zone samples were analyzed for polynuclear aromatic hydrocarbons (PAH), total particulates, and respirable free silica (7631869) at the Airco Carbon Company (SIC- 3624), Saint Marys, Pennsylvania in January, 1984. The evaluation was requested confidentially because of concern over exposures to soot, coal tar pitch volatiles, and sand in the car bottom and sagger bake operations. Forty three employees were interviewed. Two of 19 total particulate samples exceeded the OSHA standard of 15 milligrams per cubic meter (mg/m3), 17.3 and 32.7mg/m3. Benzene soluble fractions ranged from 0.5 to 5.0mg/m3. The OSHA standard for benzene soluble fractions is 0.2mg/m3. Two of seven samples of silica were above the limit of detection, 0.09 and 0.06mg/m3. In bulk samples, the benzene soluble fractions ranged from 0.44 to 860mg/gram and the PAH content from 0 to 26,124 micrograms per gram. Employees working in the bake areas reported a significant excess incidence of symptoms such as skin, nose and eye irritation, cough, sore or dry throat, chest tightness, and breathing difficulty. The authors conclude that a health hazard exists at the facility. Recommendations include enclosing vehicles used in moving electrodes, cleaning up spilled dust, and controlling fumes emitted from the sagger kilns.
