Health Hazard Evaluation Determination Report No. 76-43 A-F-429, Hersey Products Company, Inc., Gilbertville, Massachusetts

摘要

A Health Hazard Evaluation investigation was conducted by NIOSH on April 22, June 29-30, and July 1, 1976 at the Hersey Products Company, Inc. in Gilbertville, Massachusetts, a facility engaged in the founding of ferrous and non-ferrous castings. The evaluation was requested by management regarding exposure of approximately 60 'affected employees' to vapors, gases, oxides, and particulates. Environmental evaluation revealed that the shell and no-bake core makers, metal pourers, and snagger-grinder operators employed in the ferrous foundry were exposed to toxic or potentially toxic concentrations of respirable crystalline silica (7631869) dust, or carbon monoxide (630080), or iron oxide and total particulates. Non-ferrous foundry workers were exposed to toxic concentrations of crystalline silica, or inorganic lead (7439921); the 5 non-ferrous foundry workers complained of a metallic taste and occasional recurrent chills suggestive of what is commonly known as 'brass chills.' Recommendations are made for improving the prevailing environmental conditions, use of respiratory protective equipment, and medical surveillance.
