Text For Citation: 01 Item/Group: 004B 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) Oldcastle APG Northeast - On or about July 7, 2023, a Bagger working on line 5, was exposed to an 8 hour time weighted average of 65 ug/m� of air. This exposure is 1.3 times the permissible exposure limit (PEL) of 50 micrograms per cubic meter (ug/m�) of air . This exposure occurred over a 460 minute sampling period. A zero exposure was assumed for the 25 minutes not sampled. The employer did not implement engineering and work practice controls in accordance with this section. Feasible abatement methods include but are not limited to: 1) Improve or redesign the physical structure and/or ventilation draw of the ductwork to increase CFM and capture velocity. 2) Administratively reduce exposure time by rotating employees to other jobs in the facility instead of spending their entire shift bagging. Abatement certification and documentation required within 10 days after abatement date. The certification shall include a statement that abatement is complete, the date and method of abatement, and state that employees and their representatives were informed of this abatement. Abatement documentation shall include documents demonstrating that abatement is complete, such as evidence of the purchase or repair of equipment, photograph or video evidence of abatement or other written records.
