Environmental surveys were conducted and blood samples were collected on February 11 to 13, 1980, to evaluate exposures to lead (7439921), iron-oxide, manganese (7439965), and magnesium (7439954) in the steel production scrap yard area at CF and I Steel Corporation (SIC-3312) in Pueblo, Colorado. The evaluation was requested by the United Steelworkers of America, Local Union 2102 on behalf of an unspecified number of workers. Airborne concentrations of iron-oxide ranged from 1.1 to 13.6 milligrams per cubic meter (mg/m3), exceeding the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV) of 5.0mg/m3; lead ranged from 0.004 to 0.79mg/m3, exceeding the OSHA standard of 0.05mg/m3; manganese ranged from 0.01 to 0.08mg/m3, well below the ACGIH TLV of 1.0mg/m3; and magnesium ranged from 0.01 to concentrations in blood samples from the workers ranged from 6 to 34 micrograms per deciliter, below the OSHA standard of 40 micrograms per deciliter. The authors conclude that a potential health hazard exists from overexposure to lead and iron-oxide. They recommend that eating, drinking, smoking, and snuff usage be prohibited in the work area, that the respirator and blood monitoring programs be continued, and that adequate washing facilities be installed and used daily by the workers before leaving work.
