NIOSH 1979 Apr:9 pages
Worker exposure to perchloroethylene (127184) (PCE) was determined at Colonial 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 dry cleaner and spotter, and counter help. First aid supplies and a gas mask were available on the premises. Personal air and peak samples were collected. The 8 hour time weighted average (TWA) exposure of the dry cleaner was 14 parts per million (ppm) PCE. Other workers had PCE exposures of 1 or 4ppm during a shift. Peak samples collected over 5 minute periods during clothing transfer were 10 to 50ppm. Exposures of PCE were well within OSHA standards of 100ppm for an 8 hour TWA concentration and acceptable ceiling concentration of 200ppm, not to exceed a maximum 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.
