A walk through study was made of Alloy-Tech, Inc., (SIC-3321) Delran, New Jersey for the purpose of evaluating this facility for an in depth study in which potential worker exposures to silica (14808607) containing dusts would be measured and a study made of work practices and administration control programs being used to reduce these dust exposures. This facility produced ferrous castings to order in alloys ranging from iron to stainless steel. Scrap was melted in induction furnaces. Green sand molds and no bake molds were both used at the site. Castings were cleaned by steel shot in an abrasive blasting cabinet. Personal protective equipment included safety shoes, safety glasses, hard hats and ear plugs. The highest silica exposures in the facility occurred during the handling of the molding sands and during cleaning of the castings. The authors recommend the substitution of broom and shovel sand handling with large foundry grade vacuum systems to lower exposures and increased productivity. The substitution of olivine for foundry sand is also suggested. Shakeout, sand screening and sand mulling operations will also benefit from the substitution of olivine. Some modifications in equipment are suggested along with upgrading in the ventilation systems.
