Abstract
In response to a request from the United Metal Workers of America, an investigation was made of possible health hazards existing at the Dowty Corporation's welding shop (SIC-1211), Warrendale, Pennsylvania. About 100 workers on two shifts were involved in building and repairing longwall coal mining equipment. Operations included arc gouging, cutting, shielded metal arc welding, and tungsten inert gas welding. Two paint spray booths were situated adjacent to the welding operations. Worker exposures to 11 metals and elements were well below the allowable standards. Exposures to gases commonly generated by welding operations were likewise below limits. While there were no areas where exposures were greater than the allowable limits, the ventilation system was in places less than optimal and did allow a greater exposure to fumes than would have occurred had it been working up to level. One worker's exposure level for arsenic (7440382) exceeded the NIOSH 0.002mg/m3 ceiling exposure limit. In one area, exposure to perchloroethylene (127184) did exceed the lowest feasible limit for a potential carcinogen. The author concludes that worker exposures to welding fumes and organic solvents did not exceed permissible exposure limits. The author recommends measures to reduce worker exposure to solvents and welding fumes.
