Abstract
A walk through study was made of the Ingersoll-Rand Company (SIC- 3561, SIC-3563), Phillipsburg, 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 firm has operated both gray iron and steel foundries at this site, but at this point the gray iron foundry had closed. The facility was a captive foundry producing steel and stainless steel castings for the parent company. Five induction furnaces were used to melt the scrap. The foundry produced molds using an alkyd/oil molding system. Casting appendages were removed by either an air or oxygen torch in one of two ventilated booths. Grinding of bronze castings was performed in an adjacent booth. The authors recommend the modification of the semiautomatic system to allow all molds to be isolated once they are poured, and substitute of olivine sand for silica to reduce the incidence of silicosis. A potential exposure of hand grinding operators to excessive levels of silica will be lessened if the castings are as clean as possible before grinding. Improvements in the local exhaust ventilation system and in the general ventilation system are also recommended.
