Description:In response to a request from the Ohio Department of Health, an evaluation was made of worker exposure to lead (7439921) at Seville Centrifugal Bronze Inc. (SIC-3366), Seville, Ohio. The company used about 25 different alloys, with lead contents ranging from 0.5 to 8%. At the time of the visit, there were eight production workers and one foreman at the foundry. The company required half mask respirators with high efficiency particulate air filters to be worn in the foundry production area as well as other safety equipment. Personal breathing zone air concentrations were below the safety limits for several trace elements. However, cadmium (7440439) levels exceeded the NIOSH recommended exposure limit of lowest feasible exposure. Lead concentrations ranged from 98 to 230 micrograms/cubic meter and all of the personal breathing zone samples for lead exceeded the recommended limits. The pouring area had no local ventilation controls. The authors conclude that the lead levels constituted a health hazard to the workers. The authors recommend increasing the ventilation capabilities of the system by providing additional local exhaust ventilation during pouring and removal of the slag, use of a vacuum cleaner with high efficiency particulate air filters for cleaning up dust, substitution of a less hazardous mold wash, and separating the eating area from the machining and grinding area.
