Abstract
A study was made to document and evaluate effective techniques for the control of potential health hazards at Kwick Kleen Industrial Solvents, Inc. (SIC-2851), Vincennes, Indiana. This particular study was born out of a growing concern of the hazards of methylene- chloride (75092) and the need for technical advice to furniture strippers. This particular company produced, sold, and distributed furniture stripping solutions to over 2,000 furniture stripping shops. The study evaluated the local ventilation systems designed by the company for their ability to minimize the amount of methylene- chloride to which workers were exposed. Three local ventilation systems were used in conjunction with a flow over furniture stripping tank: a hood ventilation system, a PVC pipe ventilation system, and a floor ventilation system. Five different sampling setups or configurations were evaluated. Personal exposures to methylene-chloride while using local ventilation systems were about 200 parts per million (ppm) while stripping which was lower than the control system which used no local ventilation and had an average exposure of 600ppm. Local ventilation systems should be improved to lower the personal exposure levels. No control system was demonstrably better than any of the others. According to the authors, increasing the amount of air exhausted locally from the stripping area might significantly reduce exposures to methylene- chloride. Other suggestions included enclosure of the tank, as well as other tank and ventilation system designs.
