Abstract
Personal breathing zone samples and medical evaluations of workers were performed at Magma Copper Company Smelter (SIC-3331) in San Manuel, Arizona on March 6, 1980 and from April 22 to April 23, 1980. The surveys were requested by a representative of the United Steel Workers, Local 937, to determine potential hazards to workers in the reverberatory furnace and converter departments of the smelter. Personal air samples contained cadmium (7440439), copper (7440508), and lead (7439921) concentrations below the OSHA standards of 100, 200, and 50 micrograms per cubic meter, respectively. Of the 75 samples collected for sulfur-dioxide (7446095), 14 exceeded the OSHA standard of 5 parts per million. All 92 workers examined had blood lead concentrations below 40 micrograms per 100 milliliters. Four arsenic (7440382) blood concentrations were above 100 micrograms per liter, but because of overall low arsenic concentrations in the work force these elevated values were not considered significant. Sulfur-dioxide exposure was responsible for complaints of respiratory irritation, chronic obstructive pulmonary disease, asthma and skin irritation. The authors conclude that a hazard exists at the company from exposure to sulfur-dioxide. The use of respirators during high exposures reduces hazards but does not eliminate the effects of repeated short term exposures. Recommendations include updating of the ventilation system, initiation of a respirator program, use of engineering controls to reduce airborne contamination, and worker hygiene improvements.
