A walk through survey was made of the furniture stripping process at Jet Strip (SIC-7641), Boulder, Colorado to examine the effectiveness of a unique, enclosed, automated furniture stripping spray system which featured a gasket sealed lid which was in place while furniture was being stripped. Stripping was performed continuously throughout the workday. The enclosed spray system tank was 6 feet wide, 10 feet long and 4.5 feet deep. Furniture to be stripped was placed on a metal grid hung from the top of the enclosed spray system. The rack was lowered into the tank and the lip dropped to form the cover of the enclosed system. A hole in the lid was connected to a water bed mattress which lays on top of the lip. During the stripping process, vapors were emitted through this hole, causing the mattress to expand. At the completion of the stripping process the vapors slowly dissipated into the tank, leaving the mattress in its original form. A single personal sample collected during the stripping and rinsing operations showed a methylene- chloride (75092) concentration of 68 parts per million (ppm). If the rinse area were also controlled, this enclosed system could keep the concentration below the 25ppm level. This system was homemade and not commercially available. The authors conclude that the system, while apparently effective, was also expensive. It is not recommended for further study at this time.
