Industrial Hygiene Report Perchloroethylene at Janet Davis Cleaners 2165 Woodward Avenue, Detroit, Michigan.
NIOSH 1980 Jul:8 pages
Worker exposures to perchloroethylene (127184) (PCE) were surveyed on May 17, 1979, at Janet Davis Cleaners (SIC-7216) in Detroit, Michigan. The company employed 19 workers. Time weighted average (TWA) personal PCE exposures ranged from 22 to 65 parts per million (ppm), and 5 minute peak concentrations were 62 to 139ppm. Two 15 minute peak exposures were 29 and 35ppm, respectively. All exposures were below OSHA TWA, 5 minute and 15 minute PCE standards of 100, 300 and 200ppm, respectively. The author recommends that PCE exposures be kept as low as possible since the carcinogenicity of the compound has not been established. Workers should be provided with preplacement physical examinations, respirators and protective clothing, improved ventilation should be installed around dry cleaning machines and recovery and workers should be educated about units, on PCE hazards. Other recommendations include periodic inspection of equipment and PCE storage containers, direct piping of recovered PCE solvent to the base tank of the dry cleaning machine, and proper disposal of PCE solvent residues.
