The obligation
PCBUs must identify all work activities and materials that may generate RCS dust, including cutting, grinding, drilling, and polishing of silica-containing materials.
PCBUs must systematically identify RCS hazards before work begins. High-risk silica-containing materials include engineered stone, sandstone, concrete, brick, tiles, and mortar. Work processes such as dry cutting, grinding, drilling, and abrasive blasting generate the highest dust concentrations. The Code requires review of safety data sheets (SDS), site assessments, and consultation with workers.
