In response to a request from the United Steel Workers of America, Local 1011, a study was undertaken of exposures to refractory dust at the Steel Producing Tundish Repair Yard at LTV Steel (SIC-3312), East Chicago, Indiana. At the yard, tundishes used on the continual casting line were deskulled, repaired, and coated with refractory material. Personal breathing zone samples and area samples taken showed respirable dust concentrations were well below the evaluation criteria for occupational exposures of 5mg/m3. Silica (14808607) was not detected in any of the air or bulk samples. Exposure to environmental tobacco smoke was identified as a potential hazard. A walk through survey identified several potential hazards, including welding without protective screening, no eye hazard warning signs, and large dust clouds during hopper filling. The author concludes that workers were not overexposed to respirable dust or silica at the time of the survey. Environmental tobacco smoke was identified as a potential hazard. The author recommends that engineering controls and improved safety practices be instituted.
