Text For Citation: 01 Item/Group: 001D Hazard:

29 CFR 1910.1053(f)(1): The employer did not use engineering and work practice controls to reduce and maintain employee exposure to respirable crystalline silica to or below the permissible exposure limit (PEL), unless the employer can demonstrate that such controls are not feasible: b) In the Foundry Area, Main Loop Sand Fill, on or about April 9, 2024 - Engineering and work practice controls were not used to reduce and maintain employee exposures to respirable crystalline silica to or below the PEL. An employee designated as a Main Loop Sand Fill employee was exposed to respirable crystalline silica at a time weighted average exposure of 58.0 mcg/m3 during work operations. Feasible administrative and/or engineering controls would include, but not be limited to: 1. Effective ventilation over the Main Loop Close Up Area to decrease the distance between the source of exposure and the capture area; 2. Installation of a shroud or other covering over the mixer throat at the Main Loop Sand Fill to direct the flow of sand closer to the source; 3. Utilize a long handled tool to smooth the sand over the molds; and 4. Utilize employee rotation as an administrative control.
