Industrial Hygiene Report, Perchloroethylene, Peninsula French Cleaners, Burlingame, California.
Worker exposure to perchloroethylene (127184) (PCE) was determined at Peninsula French Cleaners (SIC-7216) in Burlingame, 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, a presser, and a flat work ironer. First aid supplies were available on the premises, but a NIOSH approved respirator was not. Personal air and peak samples were collected in the breathing zones of the workers. Average PCE exposures were 7, 1, and 3 parts per million (ppm) for the dry cleaner, presser, and flat work ironer, respectively. PCE concentrations of three peak samples collected over 5 minute periods during clothing transfer were 7, 7, and 8ppm; 15 minute peak samples showed concentrations of 5 and 4ppm. Exposure concentrations were well within OSHA standards of 100ppm over an 8 hour time weighted average; and for ceiling concentrations, 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.
