Industrial Hygiene Report, Perchloroethylene, Mills Park Cleaners, San Bruno, California

摘要

Worker exposure to perchloroethylene (127184) (PCE) was determined at Mills Park Cleaners (SIC-7216) in San Bruno, California on July 28, 1978. The firm was included in an industry wide mortality and industrial hygiene study of dry cleaning workers exposed to PCE. The work force comprised a dry cleaner and spotter, a presser, and two counter attendants. First aid supplies were available, but respiratory protection was not. Personal air and peak samples were collected. The average exposure of the dry cleaner was 12 parts per million (ppm) of PCE. Exposures of the presser and one of the counter attendants were 1 and 2ppm, respectively. Concentrations of four peak samples collected over 5 minute periods during garment transfer were 30, 34, 43, and 21ppm, for an average of 32ppm. Exposures were well within the OSHA permissible 8 hour time weighted average of 100ppm PCE. The author recommends that exposure to PCE be restricted as much as possible because of its potential hazard as a carcinogen.
