Environmental surveys were conducted on June 20 and 21, 1978, to evaluate the potential health hazard of an abrasive, made from lead smelter slag, used in the abrasive blasting operation at the Mark Steel Corporation (SIC-3325) in Salt Lake City, Utah. The evaluation was requested by a company representative on behalf of two affected employees. The bulk abrasive grit sample contained less than 1 percent silicon-dioxide (7631869). Three of four respirable dust samples contained no silica and concentrations of respirable dust ranged from 3.4 to 4.7 milligrams per cubic meter (mg/m3), which were below the OSHA standard of 5.0mg/m3. No cadmium (7440439) was detected in any of the samples. Lead (7439921) concentrations ranged from 0.25 to 2.34mg/m3, exceeding the from 29.0 to 69.1 micrograms per cubic meter, exceeding the 10.0 micrograms per cubic meter OSHA standard. The author concludes that employees working at the abrasive blasting operation are potentially exposed to toxic airborne concentrations of inorganic lead and inorganic arsenic, and that employees may be exposed to excess concentrations of crystalline silica. A substitute grit should be considered, a medical monitoring program should be instituted, and a respiratory protection program should be provided for concerned employees.
