In response to a request from the New Jersey Department of Health, environmental and medical surveys were conducted at Asbury Graphite Mill (SIC-1499), Asbury, New Jersey to investigate exposure to pneumoconiotic dusts. A case of pneumoconiosis had been reported in a former employee of the facility. One of 35 personal samples and 19 area samples taken and analyzed for respirable graphite (7782425) had a concentration that exceeded the threshold limit value (TLV) of 2mg/m3. The potential for overexposure to respirable crystalline silica (14808607) was demonstrated for several samples. Of the 34 personal breathing zone and 230 area samples collected for total dust, one personal and two area samples had levels which exceeded the TLV of 10mg/m3 for total particulate, not otherwise classified. The inadequacy of the local exhaust ventilation system was noted. Of the 54 current employees, 47 participated in medical studies. Chest X-rays consistent with pneumoconiosis were detected in three of the workers. Symptoms of chronic cough and chronic phlegm were reported more frequently among workers whose jobs included a higher potential for exposure to dust. Pulmonary function was inversely related to exposure. The authors conclude that a potential hazard existed from exposure to silica containing dusts. The authors recommend that local exhaust ventilation systems be improved, formal respiratory protection programs be developed, and a medical surveillance program be instituted.
