Utica Dr., Littleton, CO 80128. On or about July 16, 2024, and at times prior, the employer, Centennial Concrete & Waterproofing LLC, did not assess the exposure of each employee engaged in work operations which reasonably could be expected to expose employees to respirable crystalline silica at or above the action level. Employees were required to engage in abrasive blasting and dry grinding of concrete surfaces, as well as subsequent concrete dust clean-up using a Milwaukee battery-powered blower in the enclosed breezeways and landings of Building 19. These conditions exposed employees to respirable crystalline silica dust. Centennial Concrete & Waterproofing LLC was previously cited for a violation of this occupational safety and health standard, which was contained in OSHA Inspection 1705321, Citation 1, Item 3b, which was affirmed as a final order on May 2, 2024, with respect to the workplace located at 5105 DTC Pkwy.
