Worker exposures to manganese (7439965) were determined at Ohio Ferro Alloys Corporation (SIC-1061) in Philo, Ohio, on March 21, 1979. The survey was part of a series of NIOSH studies of occupational manganese exposure. Approximately 567 of the employees were assigned to the production areas, with greatest potential manganese exposure expected for furnacemen, helpers, and crusher operators. The company had a safety and industrial hygiene program. Medical services were furnished by a consulting physician and a full- time nurse. Primary air sampling was conducted near the working positions of the pitman and helper at one silicomanganese producing furnace. All samples were below the OSHA standard of 5 milligrams per cubic meter for manganese. Area samples collected near the working stations of the pitman, helper and charger also indicated that personal exposures to manganese were below OSHA standards. The authors conclude that this workforce should not be included in the NIOSH manganese hazard study because of the low concentrations of airborne manganese and the small number of exposed workers.
