Evaluation of eight dry cleaning shops with state-of-the-art control equipment. Report on task 1. Perchloroethylene in dry cleaning shops.
NIOSH 1999 Apr; :1-324
The Occupational Safety and Health Administration (OSHA) funded a study of control technologies for perchoroethylene (Perc) in the dry cleaning industry to determine the extent of exposure and to gather control and operational information to assist in determining technological feasibility of controlling worker exposure to Perc. The study was designed to determine the extent of exposure of employees and control technology in small and medium sized dry cleaning establishments to provide OSHA with data to be utilized in determining technological feasibility of controlling worker exposure to Perc. This report describes task one of the study, in which dry cleaning plants were selected and data taken to characterize worker exposure levels and control technology for 'fourth generation' closed-loop, dry-to-dry machines (with an integrated, in-line refrigerated condenser and a carbon absorber to recover Perc vapors during the dry cycle); the 'fifth generation' machines, having the same features as a fourth generation machines plus an internal monitor/interlock system to prevent door opening at Perc concentrations above a set level.
