Abstract
Industrial hygiene surveys of occupational exposure to perchloroethylene (127184) (PCE) at dry cleaning establishments (SIC- 3582) were conducted. Breathing zone and environmental samples from 44 dry cleaning facilities were analyzed. PCE concentrations at 42 of the facilities were below the OSHA time weighted average (TWA) standard of 100 parts per million (ppm). Thirty five of the facilities had exposures below the NIOSH recommended TWA standard of 50ppm. The geometric means of the PCE concentrations at various job stations were: dry cleaners, 22ppm; pressers, 3.3ppm; seamstress, 3.0ppm; and counter areas, 3.1ppm. The author concludes that most dry cleaning workers are exposed to PCE at concentrations below which adverse health effects occur, estimated to be 50ppm. Only workers who perform the actual dry cleaning and who maintain the processing equipment have the potential for elevated exposure. It is recommended that combination dry cleaning units be used. These units eliminate the need to transfer damp PCE exposed clothes from the cleaning to a separate drying unit, thus removing a major source of exposure.
