A NIOSH environmental survey team conducted a health evaluation of the New England Foundry (SIC-3362) to evaluate employee exposure to a number of potential health hazards in several work areas. Airborne concentrations of crystalline silica (7631869) dust were found to be potentially toxic in all of the surveyed work areas. Exposure measurements were taken for both respirable and total dust, and in both the personal breathing zone and work areas for molders, coremakers, mullers, laborers, floormen, pourers, melters, and grinders. Airborne concentrations of metal dusts and fumes of copper (7440508), zinc-oxide and tin-oxide (1314109) were within accepted exposure limits during the period of this survey. However, lead (7439921) dust and fumes were found to be potentially toxic in breathing zone measurements for melters, pourers, and grinders. Ten of the 14 hydrogen-cyanide (74908) and all of the phenols measurements were well within accepted exposure limits for the period of this survey based on coremakers breathing zone and area samples. The other four hydrogen-cyanide samples were insufficient volume to detect below the criteria concentration. Limited area sampling and colorimetric tube measurements showed no evidence of exposure to pourers, molders or shakeout workers.
