The prevalence of respiratory disease was studied in a population of foundry workers in the Cooper Energy Services Corporation Facility (SIC-3320), Grove City, Pennsylvania. Ten definite cases of silica induced pneumoconiosis, and six probable cases of silicosis, out of 181 foundry employees were found. Restrictive lung changes were demonstrated on pulmonary function tests in four of the cases. These findings were consistent with early pneumoconiosis. Work as a chipper between the years of 1951 and 1970 showed a definite correlation with risk for silicosis development. The greatest exposures to respirable crystalline silica appeared to be among chippers and grinders. All current employees exposed to an airborne concentration of respirable crystalline silica equal to or greater than 25 micrograms per cubic meter, averaged over a work shift of 8 to 10 hours, should be included in a medical screening program. The efficacy of the dust controls implemented as a result of this study should be evaluated through the existing environmental surveillance program. Limiting of worker exposure to crystalline silica of 50 micrograms/cubic meter, averaged over a work shift of 8 to 10 hours, is recommended to reduce the possibility of developing pneumoconiosis.
