An evaluation of control technology used at a filter/bag dump station at Young Industries, Incorporated (SIC-2869), Muncy, Pennsylvania was conducted in August, 1983. Respirable dust concentrations were monitored in the breathing zone, at the baghouse outlet, and at a location away from the dump station where workers emptied bags of crushed limestone. Samples were measured while the ventilation system was in operation and while not in operation using two types of baghouse filters (a polyester and a Gortex lined polyester filter). The average respirable dust concentrations before bag dumping, using polyester filter with ventilation system on were 0.105, 0.100, and 0.101 milligrams per cubic meter (mg/m3) at the baghouse outlet, away from the dump station, and in breathing zones, respectively. During bag dumping, concentrations increased to 0.143, 0.107, and 0.1112mg/m3, respectively. With ventilation system off, the dust concentration in the breathing zone increased to 0.62mg/m3 while bags were dumped. During the dumping using the Gortex filter with the ventilation system on, average respirable dust concentrations were 0.043, 0.055, and 0.41mg/m3 at the baghouse outlet, away from the dump station, and in the breathing zone, respectively. The authors conclude that the dump station does provide adequate dust control.
