Text For Citation: 01 Item/Group: 007B 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: a) On or about April 10, 2024, in the Granite Fabrication Area, the employer did not use engineering and work practice controls to reduce and maintain employee exposure to respirable crystalline silica to below the Permissible Exposure Limit (PEL) for employees working with silica containing material. On April 10, 2024, at the facility, a fabricator employee cutting and grinding stone countertops was exposed to respirable crystalline silica at an 8-hour time-weighted average (TWA) of 77 micrograms per cubic meter, approximately 1.5 times the PEL of 50 micrograms per cubic meter. Sampling was performed for 288 minutes. Zero exposure was assumed for the remaining 192 minutes.
