A preliminary evaluation was made of a prototype stripping tank for its ability to control exposures to methylene-chloride (75092) during furniture stripping operations. The tank was designed to meet the following goals: control methylene-chloride exposures to the lowest feasible limit; exhaust the optimum amount of air in order to minimize make up air costs but still control exposures; provide low cost ventilation so that small businesses could afford to purchase and operate the system; and provide versatility so that all kinds of furniture can be stripped. Personal exposure to methylene-chloride varied according to the amount of air exhausted at the prototype tank. At 700 cubic feet per minute, the worker was exposed to 144 parts per million (ppm) methylene-chloride. However, increasing the volume of air exhausted to 1,225 cubic feet per minute or higher dropped the exposure to the workers to 20ppm or less. The authors conclude that 1,225 cubic feet per minute of air appears to be the minimum and least expensive amount of air to be exhausted in order to get the lowest exposure the system is able to achieve.
