Abstract
In response to a confidential request from a group of employees of the L-Tec Welding and Cutting Systems Corporation (SIC-3548) in Florence, South Carolina, potentially hazardous working conditions were investigated. Of particular concern were skin rashes, irritation of the eyes, nose, and throat, and leukopenia in machine shop workers using solvents and degreasers. The company employed about 480 workers and manufactured welding machines. About 100 employees worked in the machine shop. The most commonly reported health concern, numbness, and skin rashes appeared related to direct skin contact with methylene-chloride (75092) vapor. Several workers using Safety-Kleen-Solvent-MS reported joint pain, fatigue, dizziness and eye irritation. Only three of the samples had methylene-chloride levels above 10 parts per million; two were obtained when the ventilation system to the degreasing unit was deactivated. Exposures to Safety-Kleen were low. Of the five workers who reported leukopenia, white blood cell counts were below the race specific range in only one; workplace substances have not been associated with the development of leukopenia. The authors conclude that direct skin exposure to methylene-chloride could cause some of the numbness and skin irritation. Exposures were not in a range that would be likely to cause symptoms such as headaches and dizziness.
