Health hazard evaluation report: HETA-90-092-L2083, Bethlehem Steel, Chesterton, Indiana.
NIOSH 1990 Nov; :1-25
In response to a request from the United Steel Workers of America Local 6787, an investigation was undertaken of possible hazardous working conditions at the 160 inch plate mill at Bethlehem Steel, Chesterton, Indiana. A significant number of employees were experiencing symptoms of eye and respiratory irritation which could be linked to workplace exposures. There was no evidence of severe occupational illness. Low to moderate exposure to air contaminants were measured, including metals, sulfur-dioxide (7446095), nitrogen- dioxide (10102440), and carbon-monoxide (630080). No single contaminant was identified as the cause of eye and respiratory irritation. The authors conclude that the symptoms were caused by a combination of contaminants released by the cutting operations and by the heat treatment and tempering furnaces. The authors recommend that exposure to these irritants be controlled to minimize employee discomfort. The ventilation system should be improved, in part through the use of local exhaust or other engineering controls.
