Worker exposure to toxic metal fumes, flux fumes, and gases generated during routine welding and cutting operations was studied. The investigation was requested by the United Mine Workers of America and was performed on November 14 and 15, 1979. The study was prompted by worker concern over a possible excess of mortality among welders in the shop. A total of 17 welders and one blacksmith worked in the welding shop. Some welders were exposed to inorganic nickel in concentrations higher than the NIOSH recommended standard of 15 micrograms per cubic meter (mg/cu m). Most of the welders were exposed to hexavalent chromium in concentrations above the American Conference of Governmental Industrial Hygienists standard of 0.5 mg/cu m. Three of five 15-minute personal samples exceeded the NIOSH recommended limit of 1.8 mg/cu m for nitrogen-dioxide. It was concluded that there was significant overexposure to nickel, hexavalent chromium, and nitrogen dioxide. Recommendations were made.
