Acting on a request received from an authorized representative of employees regarding their concern over the exposure of workers to creosote (8021394) and pentachlorophenol (87865), a health hazard evaluation was conducted by NIOSH at the wood treating operation (SIC-2865) of Koppers Company, North Little Rock, Arkansas. The results of air sampling revealed that the workers were exposed to potentially toxic levels of polynuclear aromatic hydrocarbons, while exposures to airborne concentrations of pentachlorophenol were not toxic at the levels encountered. Interviews of nine of the 11 affected workers disclosed an episode of eye irritation and four cases of skin discoloration. Examination of the workers skin revealed two cases of mild oil folliculitis and three workers with pitch warts, both conditions probably due to creosote exposures. About 45 percent of the workers interviewed and examined had either elevated or borderline elevated blood pressure levels, although definite conclusions could not be drawn regarding the relationship of the pressure phenomena to occupational exposures. Recommendations are made for improving the existing working conditions and for the application of an occupational medical program.
