Walk-Through Survey Report at Union Carbide Corporation, Battery Products Division - Edgewater Plant, Cleveland, Ohio.
Worker exposure to manganese (7782505) and particulate materials was determined at Union Carbide Corporation, Battery Products Division (SIC-3692), Edgewater facility in Cleveland, Ohio on January 29, 1980. The facility was under consideration for inclusion in a NIOSH industry wide study of occupational exposure to manganese. Of 600 workers at the facility, about 30 had significant potential for exposure to manganese in the dry cell production process. The facility had medical industrial hygiene and safety programs. New employees were given medical examinations, and periodic physicals were furnished to some employees, depending upon their job and age. Airborne manganese concentrations at the mixer operator's station and near the cell assembly machines were well within the OSHA 15 minute ceiling value of 5 milligrams per cubic meter. Particulate concentrations ranged from 0.191 to 0.734 milligrams per cubic meter. The authors conclude that the engineering controls and material handling techniques appear to prevent the release of significant quantities of manganese and other particulate material into the workplace air. They do not recommend the inclusion of this facility in further NIOSH studies of occupational exposure to manganese because of the low concentrations of airborne manganese.
