NIOSH 1980 Jul:8 pages
An on site visit was made to Dubarry Cleaners, Detroit, Michigan, as part of an industrywide mortality and industrial hygiene study of dry cleaning workers exposed to perchloroethylene (127184) (PCE). Air samples were taken at the facility and the time weighted average exposure to PCE was calculated to be 23 parts per million (ppm) with 5 minute peak exposures ranging from 33 to 141ppm. A 15 minute sample collected indicated a 34ppm peak of PCE. The exhaust ventilation through the washer door measured 60 feet per minute. Leaks were noted with the door closed. Temperature readings ranged from 16.7 to 21.1 degrees-C with the relative humidity varying between 22 and 38 percent. The author recommends that prospective employees receive preemployment physical examinations, that all dry cleaning machines and recovery units be equipped with a unit blower capable of providing an indraft velocity through the loading door of 100 feet per minute for each square foot of door opening, that respiratory protection be provided for emergency use, that protective clothing to prevent skin exposure be provided, that all employees be informed as to hazards, symptoms and precautions to take, that storage containers, equipment, piping, and valves be checked for leaks, and that recovered solvent be piped directly to the base tank of the dry cleaning machine and residues containing solvent be disposed of in a manner which would not create a health hazard.
