Abstract
Worker exposure to perchloroethylene (127184) (PCE) was determined at Ruby's Cleaners (SIC-7216) in Hayward, 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 a presser, dry cleaners and spotters, and counter help. First aid supplies were provided on the premises, along with a chemical cartridge that contained an expired Bureau of Mines date of approval. Personal air, peak, and samples were collected. The 8 hour time weighted average (TWA) exposure of the presser was 7 parts per million (ppm) PCE; the 8 hour TWA concentration in the vicinity of the spotting table was 10ppm. Concentrations of two peak samples collected over 5 minute periods during clothing garment transfer were 84 and 122ppm; a 15 minute peak sample during transfer indicated a PCE concentration of 65ppm. Concentrations of samples collected over a front dryer door were 446, 983, and 139ppm, for a TWA of 540ppm. Exposures to the workers were within OSHA standards of an 8 hour TWA concentration of PCE of 100ppm and a 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.
