Worker exposure to perchloroethylene (127184) (PCE) was determined at Golden State Cleaners (SIC-7216) in San Francisco, California on July 25, 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, two pressers, counter attendants, and a leather cleaner. First aid supplies were available and a gas mask was provided for the dry cleaner. Personal air samples, including peak samples, were collected in the breathing zone of the workers. The exposure of the dry cleaner was 58 parts per million (ppm) of PCE during an 8 hour shift. Exposures of two pressers were 14 and 17ppm. A counter attendant was exposed to 8ppm, and one of three owners had an exposure of 11ppm. Peak samples collected over 5 minute periods during garment transfer averaged 72ppm. Although exposures to PCE were within OSHA standards of 100ppm of PCE for an 8 hour time weighted average, exposure of the dry cleaner was above the NIOSH recommended time weighted average concentration of 50ppm. The author recommends that exposure to PCE be restricted as much as possible because of its potential hazard as a carcinogen.
