Industrial Hygiene Walk-Through Survey Report on Organophosphorus Exposures at Rochester Products Division, General Motors Corporation, 100 Lexington Avenue, Rochester, New York

摘要

Worker exposures to organophosphorus (OP) esters were determined at the Rochester Products Division of General Motors Corporation (SIC-3592) in Rochester, New York, on October 12, 1979. The company was being considered for inclusion in a NIOSH study of delayed neurotoxic effects of occupational OP exposure. The die cast department surveyed had approximately 219 employees. A safety program was in existence, and periodic environmental sampling was conducted. Showers and facilities for changing clothes were provided. There was a full time physician available to provide preemployment and periodic physical examinations. Employment records provided demographic information and employment history. Exposure concentrations to OP esters were relatively low, with triphenyl-phosphate being one of the major components. Trace concentrations of diphenyl-2-isopropyl phenyl phosphate were found along with 11 other unidentified OP esters. The author concludes that because of the lack of identification for all OP ester exposures and the uncertainty of OP ester skin absorption, the facility is not suitable for inclusion in the proposed NIOSH study.
