• Description:
  A visit was made to Pennsylvania Glass Sand Corporation, Berkeley Springs, West Virginia to evaluate control measures in place to protect workers from silica (14808607) dust exposures. Two dust suppressant techniques were in use. The first called for the use of an agglomerating/foaming agent, Deter(R), which was sprayed into whole grain sand during its transfer through the old screen tower building. The second method used exhaust ventilation during the bulk loading of silica-flour into enclosed hopper cars which controlled fugitive dust emissions. Exhaust ventilation systems were used to capture point source emissions from the six pebble mills, the three packer stations and the bulk loading stations. An exhaust ventilation system was also used to control dust emissions during the bulk loading of silica-flour into closed hopper trucks and railroad cars. The injection of the agglomerating agent reduced dust emissions by 20 to 67 percent. The bulk loading of silica- flour under local exhaust ventilation reduced dust levels from 90 micrograms/cubic meter total dust and 80 micrograms/cubic meter silica dust. The local exhaust ventilation systems at the three silica-flour packing stations showed varying degrees of effectiveness as a result of the design, total air movement control, and housekeeping practices. Other existing and planned control strategies were briefly discussed.
