In response to an employee request, an investigation was begun into possible hazardous working conditions at A K Steel Coke Works (SIC- 3312), Ashland, Kentucky. Employees were concerned about exposure to contaminants during collection and blending of coal-tar sludge with coal. The facility employed 400 workers and produced about 1,000,000 tons of coke annually at full capacity. A questionnaire was administered and measurements were taken of 1-hydroxypyrene (5315797) (1-HP), as an indicator of polycyclic aromatic hydrocarbon exposure. Samples were taken from 18 of 22 workers in the coal handling area. Testing revealed exposures to coal-tar-pitch volatiles, polynuclear aromatic hydrocarbons, and potentially benzene (71432), which exceeded the recommended exposure levels during the processing of coal-tar sludge. Improper use of personal protective equipment was also noted. Urine 1-HP levels indicated excessive exposures to pyrene (129000). The authors conclude that a health hazard existed due to exposure to contaminants. There was a potential for skin contact with coal-tar sludge. The authors recommend specific measures to reduce the hazardous exposures to the workers at this site.
