Abstract
In September 1998, a local exhaust ventilation (LEV) system was installed on a dry-to-dry cleaning machine with a refrigerated condenser and activated charcoal filters. In this study, a dry cleaning store was selected that had a single machine that was at least 10 years old, a LEV system was installed at a cost of approximately $2,500, and the reduction of exposures to perchloroethylene (PERC) to the employees was assessed. This task was completed as a part of an Interagency agreement between NIOSH and OSHA. Full-shift time weighted average (TWA), short duration ceiling, and 15 minute short-term exposure levels (STEL) PERC exposure concentrations were measured for the workers at the store and in select areas in the store. PERC exposure concentrations were measured for the workers at the store and in select areas in the store. PERC exposures were assessed before and after the LEV system was installed and with and without the LEV system operating. Comparisons were made to determine to what extent PERC exposures were reduced with the addition of the LEV system. The LEV system installed demonstrated that a simple inexpensive system can be installed that will significantly reduce worker exposure to PERC fumes while loading and unloading cloths form a dry cleaning machine.
