An in depth study was conducted at Appearance Plus Cleaners (SIC- 7216), Cincinnati, Ohio to evaluate control of worker exposure to perchloroethylene (127184) (PERC) from two nonvented, refrigerated, dry to dry machines, and to provide recommendations for improvement. In the dry cleaning building, two machines were located along the center of the rear wall. The shop used an average of 30 gallons of PERC every 2 to 2.5 months. Each machine processed approximately ten loads of clothing for a total of about 600 pounds of clothing a day. Exposure to PERC was the primary health hazard for workers in dry cleaning facilities. Exposures were maintained well below 25 parts per million (ppm). The time weighted average exposure for a machine operator was 7.8ppm. Loading and unloading of the dry cleaning machines had the greatest impact on exposures. The average exposure during loading was 98ppm; during unloading, the average exposure was 89ppm. No visible leaks were found in the machines, probably because they were new. The authors recommend the addition of a simple, inexpensive, external local ventilation system. Other recommendations include use of personal protective equipment at spotting stations to reduce dermal exposure, and the development of a proper respirator program.
