Employees were required to grind dry concrete surfaces in an enclosed area with a 7-inch Makita powered grinder.   The employer did not ensure the Makita grinder was equipped with a grinding wheel or blade shroud as well as a dust collection system that provided 25 cubic feet per minute (cfm) or greater of airflow per inch of grinding wheel diameter, a filter with 99% or greater efficiency, and a cyclonic pre-separator or filter-cleaning mechanism.  This condition exposed employees to respirable crystalline silica.  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 3a, which was affirmed as a final order on May 2, 2024, with respect to the workplace located at 5105 DTC Pkwy.
