Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 73-130-94, 1973 Nov; :1-10
Environmental measurements in the breathing zone of welders and employee interviews and urinalysis for fluorides indicate that no actual health hazard exists from exposure to welding exhaust gases at a foundry facility producing corrosion and heat-resistant high alloy castings. A potential health hazard is considered to exist from exposure to welding fumes, especially of alloys containing a high percentage of chromium (7440473) and nickel. Data are given for the concentrations of iron oxide, nickel (7440020), chromium, manganese (7439965), and molybdenum (7439987) in the air.
