Abstract
A health hazard evaluation of employee exposure to air contaminants in the Bronze Foundry (SIC-3362) of the Hersey Products Company reveals that 27 percent of the personnel respirable samples in the coremaking, molding, shakeout and fettling areas showed exposures to crystalline silica in excess of the NIOSH recommended standard, to the effect that coremakers, molders, utility men on shakeout and fettlers are exposed to potentially toxic concentration of airborne respirable crystalline silica (7631869). The concentrations of formaldehyde (50000) do not exceed the evaluation criteria, although evidence exists that irritant toxicity to this agent is present in the exposed workers. The levels of toluene (108883) encountered cannot account for infrequent nose and throat soreness elicited by 2 workers. Bronze alloy furnace tenders and pourers are frequently exposed to lead levels in excess of the recommended standards; the same is valid for casting chipping and grinding personnel, who also undergo excessive copper (7440508) dust exposure.
