NIOSH 1979 Apr:11 pages
Worker exposure to perchloroethylene (127184) (PCE) was determined at Roy's Cleaners (SIC-7216) in Redwood City, California on July 28, 1978. Four persons were employed at the facility. First aid supplies were provided but none of the employees had formal first aid training. The gas masks provided were not NIOSH approved. The dry cleaner was exposed to 13 parts per million (ppm) PCE; the three other employees were exposed to 1ppm. The average concentration of PCE around the washer was 5ppm. Five minute peak samples collected during clothing transfer measured 1, 21, 32 and 12ppm. Leaks were found at the rear of the dryer and on the control unit. Dry bulb temperatures ranged between 21.7 to 23.9 degrees C, and the relative humidity ranged from 52 to 58 percent. The author notes that exposures to PCEs were within the OSHA standard of 100ppm. He recommends preplacement physical examinations; engineering controls; respiratory protection for use during emergencies; protective clothing; educating employees to the hazards, symptoms, effects and precautions concerning the use and handling of PCE, and periodically checking storage containers, equipment, piping and valves for leaks.
