A health hazard evaluation determination conducted at the Quincy Steel Casting Company (SIC-3321) revealed potentially toxic exposures to crystalline silica (7631869) and iron oxide. Excessive silica exposures were found in all areas of the foundry and cleaning room, while iron oxide exposures occurred throughout the cleaning room and torch cut-off operation. Potentially toxic exposures were not found for lead (7439921), manganese (7439965), zirconium (7440677), fluoride, p,p'-diphenylmethane-diisocyanate, zinc (7440666) and isopropanol (67630). Limited area samples for asbestos (1332214) fibers were below the current recommended criteria. Recommended control measures are described.
