Abstract
Worker exposure to perchloroethylene (127184) (PCE) was determined at Lockwood Cleaners (SIC-7216) in Oakland, 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 pressers, a cashier, a bagger, and a dry cleaner and spotter. Personal and area air samples were collected. The 8 hour time weighted average (TWA) exposure of the dry cleaner was 65 parts per million (ppm) PCE. Samples collected over the work shift indicated concentrations of 26ppm PCE in the dry cleaning area, 48ppm in the spotting area, and 42ppm near the work bench. Other samples collected in the dry cleaning area indicated PCE concentrations of 25 and 50ppm. A detector tube sample collected during clothing transfer indicated 225ppm PCE. Exposure was within OSHA standards of 100ppm for an 8 hour TWA concentration of PCE and an acceptable ceiling concentration of 200ppm, not to exceed a maximum of 300ppm for 5 minutes in any 3 hour period, but exceeded a NIOSH recommendation that no employees be exposed to PCE in excess of 50ppm, determined as a TWA for up to a 10 hour workday, 40 hour workweek; and a ceiling concentration of 100ppm, as determined by 15 minute samples collected twice daily. The author recommends that exposure to PCE be restricted as much as possible because of its potential hazard as a carcinogen.
