Worker exposure to perchloroethylene (127184) (PCE) was determined at Esrik Cleaners (SIC-7216) in San Francisco, California on July 26, 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 pressers, a seamstress, and dry cleaners and spotters. First aid supplies were available on the premises, but respiratory protection was not. Personal air and peak samples were collected. The average exposure of a dry cleaner was 38 parts per million (ppm) PCE over a 7 hour shift; exposures of the pressers and seamstress were 1 or 2ppm. PCE concentrations of three peak samples collected over 5 minute periods during garment transfer were 30, 20, and 7ppm, averaging 19ppm. Concentrations of two 5 minute peak samples during transfer were 31 and 27ppm. Exposures were well within OSHA standards of 100ppm for an 8 hour time weighted average (TWA) concentration of PCE and an acceptable ceiling concentration of 200ppm, not to exceed a maximum peak of 300ppm for 5 minutes in any 3 hour period. The author recommends that exposure to PCE be restricted as much as possible because of its potential hazard as a carcinogen.
