Health hazard control methods, work processes, and existing control technologies were evaluated at Ohio Brass Company (SIC-3264), Barberton, Ohio, in September, 1982. The company employed 550 workers involved in the production of ceramic electrical insulations from feldspar, kaolin, alumina (1344281), locally mined flint, and ball clays. Production sized raw materials were formed into a batch mixture, combined with water, mixed, and filtered through a 120 mesh screen to form slip. The slip was dehydrated into clay press cakes which were charged into a pug mill. The material was extruded and cut into appropriate lengths, then shredded and blended, and automatically cut into blanks. The blanks were formed and trimmed into a fully formed insulator body. After drying, the body was glazed, formed with portland cement, fired, inspected, and cured. The insulators were automatically cleaned and tested, then packed and shipped to the consumer. Monthly inspections of the work areas were conducted along with periodic environmental sampling. Workers were provided with safety glasses, hearing protectors, respirators, and safety shoes. Local exhaust ventilation was used throughout the facility. The author does not recommend an in depth study of this company since there is no raw material crushing and grinding operation.
