A walk through survey was conducted at the Division Creek Sand Plant (SIC-1446), Millville, New Jersey as part of a study to determine the need for improving engineering controls in a sand mining operation. The Unimin Corporation supplied washed sand for the glass industry. Sand was dredged, sized, washed, purified of iron containing impurities, dried, and loaded onto rail cars or trucks. A total of 24 hourly and nine salaried individuals were employed at this facility. In the processing facility the operator worked in an air conditioned control room and in the drying and loading areas, workers spent considerable time in air conditioned sheds. Roof fans provided dilution ventilation in the processing plant. No local exhaust was used. In the drying facility air from the fluidized bed dryer was exhausted through a wet scrubber. A bag house sitting atop one silo provided bin venting for the silos and exhaust for the final bucket elevator and the loading spouts. Processing areas were remarkably free of spilled sand. A tank truck with water sprayers was available for dust control along haulage ways. Safety shoes, glasses and hard hats were required in all areas. Respirators were required in designated areas. A safety brochure outlining essential safety and health requirements was mandatory reading for all personnel and visitors. Routine monitoring of silica (7631869) exposure was performed twice yearly. The authors suggest that since this site is using ventilated loading spouts, not common in this industry, a comparison might be made between this method and more conventional techniques.
