Walk-through Survey Report of the Steel Manufacturing and Alloying Operations at ARMCO Middletown Works, Middletown, OH., March 15, 1979.

Abstract	The survey of the ARMCO Steel Corporation, Middletown Works, in Middletown, Ohio, was conducted as one of a series of initial walk-through surveys in a representative sample of firms manufacturing or using products containing manganese. Airborne manganese levels on the charging floor of Basic Oxygen Furnace No. 15 were substantially below permissible exposure limits, despite the fact that the man-cooling fan was not operated during the sampling period. Observation of work practices indicated that workers spend very little time in the dustier areas of the charging floor, consequently, personal exposure levels would be well below the concentrations observed during the sampling period. Based on the low levels of airborne manganese observed, and the small number of workers exposed, it is expected that the ARMCO Middletown Works will not be included in the NIOSH study of occupational exposure to manganese.
