HHE Report No. HETA-92-157-2304, The General Castings Co. - Domestic Division, Shippensburg, Pennsylvania.
In response to a request from management at the General Castings Company (SIC-3321), located in Shippensburg, Pennsylvania, an investigation was made into worker exposures in the coremaking, molding, pouring, melting, shakeout, sand handling, and cleaning areas of the facility. The facility was a gray and ductile iron foundry. An electric induction and two holding furnaces were used to produce molten iron. No local exhaust hoods or air pollution control devices for the induction furnaces were in place. Four coremaking processes were used: hot shell, oil baked, cold box, and no bake. An industrial hygiene survey was conducted and included personal breathing zone and area air sampling, work practice evaluation, engineering control measures, and noise exposure assessment. The author concludes that workers were overexposed to respirable silica (14808607), lead (7439921) and noise. Carbon- monoxide (630080), chrysotile (12001295) and benzene (71432) exposures constituted a potential health hazard to employees in the coremaking, molding, pouring, cleaning and shakeout areas. The author recommended measures for reducing exposures and improving the use of respiratory protective devices.
