• Description:
  The results of a NIOSH project for controlling methylene-chloride (75092) exposures during commercial furniture stripping operations were summarized. Scientists from the Engineering Control Technology Branch, NIOSH are conducting field studies to develop, document, and evaluate techniques for controlling methylene-chloride exposures in furniture stripping facilities. They designed, installed, and evaluated a new local ventilation system in one facility where workers who stripped furniture experienced methylene-chloride exposures of 600 to 1,150 parts per million (ppm). The new ventilation system incorporated a local ventilation hood that contained a slot hood and downdraft hood and supplied an increased amount of makeup air to the stripping area. A panel of charcoal filters that caused a pressure drop which hindered air flow was removed. The new ventilation system was tested over 3 days using charcoal sorbent tubes to collect the methylene-chloride. The system was able to reduce methylene-chloride exposures to a geometric mean of 25ppm. The authors conclude that the facility should use the new local ventilation system as a combined hood. They also recommend that cross drafts be eliminated and ventilation controls be installed in the rinse area. [Description provided by NIOSH]
