Abstract
A survey of occupational hazard controls was conducted at Koppers Company, Incorporated, Organic Materials Group (SIC-2865), in Chicago, Illinois on June 22, 1982. The company employed about 100 workers. There was no on site industrial hygienist, but personal monitoring was periodically performed for workers. There was a safety department that provided appropriate equipment. Major potential hazards were exposure to coal-tar (8007452) and its derivatives and to phthalic-anhydride (85449). All materials used were flammable and there was a risk of burns from handling hot tar and pitch (61789604). In the coal-tar facility, fume exposures were controlled by isolating workers and venting fumes to a scrubbing tower or thermal oxidation unit. Local exhaust ventilation with particulate removal was used to control dust. In the phthalic- anhydride facility, sublimation boxes were installed on tank vents to convert fumes to fluff, which presented less danger from contact than if allowed to form indiscriminately. Local exhaust ventilation was used to control dust from flaking operations. Hot pipes and tanks were insulated and liquids were contained in a closed process. The authors conclude that alternatives to fluff boxes should be investigated. They recommend an in depth study of coal-tar-pitch and phthalic-anhydride vapors.
