Cincinnati, OH: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 79-43-663, 1980 Aug; :1-7
Environmental samples for coal tar products were analyzed, and medical interviews were conducted at the Harbison-Walker Refractories (SIC-3297), Number 1, in Clearfield, Pennsylvania, on September 26 to 27 and June 27, 1979, to determine employee exposure to benzo(a)pyrene (50328), and fluoranthene (206440). The evaluation was requested by a representative of the United Steel Workers of America. The benzene soluble fractions for coal tar products ranged from 0.03 to 1.42 milligrams per cubic meter (mg/cu m). Four of the seven sample concentrations exceeded the OSHA limit of 0.2 mg/cu m for coal tar products. Benzo(a)pyrene concentrations ranged from 0.3 to 4.98 micrograms per cubic meter, chrysene from to 0.87 micrograms per cubic meter, benzo(a)anthracene from 0.22 to 2.41 micrograms per cubic meter, and fluoranthene from 0.11 to 1.00 micrograms per cubic meter. Five of the eight workers interviewed reported no health complaints. One worker reported photosensitization. Two workers reported adverse reactions to creosote exposure. The author concludes that workers are exposed to hazardous concentrations of coal tar products. He recommends installation of local exhaust ventilation, processing modifications, periodic maintenance of all equipment involved with the handling of coal tar products, use of protective clothing and equipment, and periodic atmospheric monitoring.
