Industrial hygiene report, perchloroethylene, Top Hat Cleaners, San Mateo, California.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, IWS 71-24, 1979 Apr; :1-9
Worker exposure to perchloroethylene (127184) (PCE) was determined at Top Hat Cleaners (SIC-7216) in San Mateo, California on July 27, 1978. The firm was included in an industry wide mortality and industrial hygiene study of dry cleaning workers exposed to PCE. The work force included a dry cleaner and spotter and a presser. First aid supplies and a chemical cartridge respirator, which was not NIOSH approved, were kept on the premises. Personal air samples were collected in the breathing zones of the dry cleaner and presser. Average exposures to PCE for the dry cleaner and presser were 36 and 9 parts per million (ppm), respectively. Concentrations of two peak samples collected during garment transfer were 315 and 128ppm. One of these samples exceeded the OSHA maximum peak of 300ppm; all other samples were within the permissible 8 hour time weighted average concentration of 100ppm. The author recommends that exposure to PCE be restricted as much as possible because of its potential hazard as a carcinogen.
