In response to a management request, an evaluation was made of possible hazardous working conditions at ARMCO Advanced Materials Corporation (SIC-3312), Butler, Pennsylvania. ARMCO produced primarily specialty steel products. An indirect method of electric heating was used at the facility to make steel. Concern was expressed about employee exposures to infrasound, electromagnetic radiation, and various dusts throughout the melt shop. The investigation was then expanded to include radiofrequency exposures at the Ultra-Rapid Annealing (URA) furnace located in the Strip Coating and Silicon Anneal Building (SCSAB). Air samples analyzed indicated that the recommended levels were being exceeded for chromium (7440473), manganese (7439965) and lead (7439921). Radiofrequency radiation measurements at the URA furnace and the visible radiation levels near the electric arc furnaces in the melt shops exceeded the appropriate evaluation criteria. The authors conclude that health hazards existed during the survey from excessive airborne levels of hexavalent chromium, manganese, and lead, high levels of optical radiation near the electric arc furnaces, and radiofrequency radiation at the URA furnace. The authors recommended measures to lower these exposures and suggested the institution of medical and environmental surveillance programs.
