Industrial hygiene surveys were conducted at two facilities of the Suburban Dry Cleaners, Cincinnati, Ohio, April 6-7, 1977, as part of an industry-wide study of dry cleaning workers exposed to perchloroethylene (127184). The dry cleaning process (SIC-2842) is described. Two personal samples and 9 area samples were collected and analyzed for perchloroethylene. Although the workers' time- weighted average exposure to perchloroethylene was well below the OSHA standard of 100 ppm, the potential for intermittent or peak exposures to higher concentrations exists, especially on busier days, or during repair and maintenance, or emergency spills. Recommendations include: pre-placement physicals, respiratory protection for brief exposures at concentrations in excess of the environmental limit, the use of gloves during unloading, informing workers of the hazards, and periodic checks for leaks.
