• Description:
  An on site visit was made to the Minerals Division of Grefco, Inc. (SIC-3295), Lompoc, California for the purpose of evaluating the methods used at this location to control employee exposure to hazardous materials. This company produces a variety of diatomaceous-earth (68855549) (DE) products used as filter aids and mineral fillers in water and food processing, pigments, insulation, cleansers, carriers for insecticides and catalysts, match heads and other products. About 100,000 tons of crude diatomite, an amorphous silica were processed annually. Exhaust ventilation was provided at each packer station and inside the press pit, and at a palletizing station. Airborne dust in the pit was captured as it was generated during pallet loading and compacting. A trough with water sprays removed product falling from packers and during bag handling. The water spray significantly reduced the airborne dust concentrations. Outside grounds were kept clean by immediately sweeping up spills and frequently washing down with water. Monitoring, primarily through personal samples for respirable dust, was done quarterly in dusty areas. Wind breaks were installed in the area of the recycle hoppers. The author concludes that an in depth study at this site may be desirable.
