A health hazard evaluation was carried out at the slab yard of Inland Steel Corporation, East Chicago, Indiana. Eight workers were employed at this slab yard during each shift, with three shifts per day. Samples of breathing zone air and area air were analyzed for respirable crystalline silica (14808607) and total respirable particulate matter. Measurements were also taken of sulfur-dioxide (7446095) and metallic fumes and dusts. Total respirable particulates were below the recommended limits and no detectable quantities of quartz or cristobalite were found. Airborne breathing zone concentrations of iron-oxide (1309371) ranged from 0.1 to 1.6mg/m3; of lead (7439921) from 0.003 to 0.006mg/m3; of manganese (7439965), 0.003 to 0.012mg/m3; and of copper (7440508), (0.002 to 7.0 to 10.0 parts per million (ppm); sulfur-dioxide, 0.5 to 10.0ppm; and nitrogen-dioxide (10102440), not detectable to 0.50ppm. Symptoms among the workers included cough, expectoration of dust daily, sinus difficulty, and dry mouth. Recommendations were offered concerning medical examinations and testing, respirator use, monitoring of sulfur-dioxide levels in crane cabs, installation of louvers along the south wall of the slab yard, monitoring of high carbon steel slab production, and monitoring of number 6 crude oil for benzene (71432).
