Exposures to iron ore dust (15438310), lead (7439921), crystalline- silica (14808607), and total particulates were evaluated on June 6 to 8, 1978 in the ore handling department at the C. F. and I. Steel Company (SIC-3312) in Pueblo, Colorado. An evaluation request came from the United Steel Workers of America on behalf of approximately 200 affected workers. Concentration of iron ore dust and total particulates in the work environment exceeded the OSHA standards of 10 milligrams per cubic meter (mg/m3) for each contaminant. Only one of five samples for crystalline silica exceeded the OSHA standard of 10 milligrams per meter divided by the percentage of respirable quartz plus 2. The results of the lead determinations were not included. Workers reported symptoms compatible with excessive exposure to iron ore dust. The author concludes that a health hazard does exist at this company. Recommendations are included for respirator use, workplace hygiene, and improved ventilation.
