Text For Citation: 03 Item/Group: 001B 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 PEL, unless the employer can demonstrate that such controls are not feasible: Foundry Area: On or about April 17, 2024, and at times thereafter, the employer did not use engineering and work practice controls to reduce and maintain employee exposure to respirable crystalline silica at or below the PEL. Employees were overexposed at 64 micrograms of respirable crystalline silica per cubic meter of air (?g/m�) as an 8-hour time-weighted average (8-hr TWA). These exposures were approximately 1.3 times the permissible exposure limit (PEL) of 50 ?g/m3 and were determined during a sample period of 378 minutes, using zero exposure for the unsampled portion of the 8-hour shift. Employees performed tasks that exposed them in the following locations that were at or within close proximity to the exposure source: a) Abrasive Blasting Cabinets b) Knockout Stations c) Vertical Band Saw Station d) Vertical Belt Sander Station
