Industrial Hygiene Report Perchloroethylene at Morton Drive-In Cleaners, Chicago, Illinois, Report No. IWS-71-46.
NIOSH 1980 Dec:11 pages
An industrial hygiene survey was conducted at the Morton Drive In Cleaners (SIC-7216) located in Chicago, Illinois for the purpose of gathering additional information regarding employee exposure to perchloroethylene (127184) (PCE). This particular cleaning establishment had been using PCE as a dry cleaning solvent at this location since 1950. The facility is a one story building approximately 40 feet by 100 feet. About 20 gallons of PCE are consumed each week during the dry cleaning of 1,200 pounds of clothing. The work force includes six persons. Air samples for PCE had never before been collected. Exposures to PCE were well within NIOSH recommendations, 50 parts per million (ppm), determined as a time weighted average for up to a 10 hour work day, 40 hour work week with ceiling concentrations not to exceed 100ppm during a 15 minute period. However, since PCE is regarded as a possible carcinogen, further reductions were suggested and several recommendations were given to make this possible. These suggestions included the installation of an exhaust ventilation system, use of respiratory protection during emergencies such as spill cleanup, use of protective clothing to prevent skin contact, education of the employees as to the dangers, proper storage of supplies and monitoring of equipment for leaks.
