In response to a request from management, a study was made of possible hazardous working conditions at C-F-and-I Steel Company (SIC-3313), Pueblo, Colorado. The company produced steel in electric arc furnaces. Workers in the vicinity of the electric arc furnace had complained of bad odors and tastes, and respiratory irritation. Breathing zone and general room air samples were tested for sulfur-dioxide (7446095), arsenic (7440382), cadmium (7440439), lead (7439921), total particulate, and crystalline silica (quartz (14808607) and cristobalite (14464461)). Seven general area sample measurements ranged from 0.2 to 1.7mg/m3 for sulfur-dioxide. One breathing zone sample registered 0.78mg/m3. Arsenic was found in one sample at a level of 0.02mg/m3. Cadmium was found in one of 11 samples at 0.006mg/m3. Lead was present in all 11 samples ranging from 0.004 to 0.3mg/m3. Total dust measurements were 14 and 12mg/m3. Respirable dust samples contained 1.5 and 1.4mg/m3 respirable dust; free silica samples were 0.5 and 0.2mg/m3 (quartz). The author concludes that a potential health hazard existed from exposure to arsenic, cadmium, lead, and crystalline silica. The author recommends that specific improvements be made in respiratory protection, and that workers be notified when sulfur compounds are being added to the steel.
