Personal air samples were analyzed for total particulate concentrations, iron-oxide fumes, and particulate inorganic fluorides, at the Bethelehem Steel Corporation (SIC-3312), in Chesterton, Indiana, on June 3 to 6, 1980. A representative of the United Steelworkers of America, Local 6787, requested the evaluation on behalf of approximately 20 affected workers in the continuous castor shop. Total particulate concentrations ranged from 0.8 to 2.2 milligrams per cubic meter (mg/CuM), compared with the OSHA standard of 15mg/CuM. Iron-oxide concentrations were in the range of 0.04 to 1.0mg/CuM, with the OSHA standard being 10mg/CuM. Fluoride concentrations ranged from 0.04 to 1.7mg/CuM, compared with the OSHA standard of 2.5mg/CuM. Seventeen of the 20 workers interviewed reported one or more acute, intermittent work related health problems, predominately respiratory tract and mucous membrane irritation. The authors conclude that a health hazard from particulate or iron-oxide fume did not exist at this facility, although they suggest that workers were exposed to irritant concentrations of fluorides. They recommend that additional environmental monitoring be conducted and that appropriate respiratory protection be provided to all workers during periods of increased dust generation.
