Silica dust. Dust containing respirable crystalline silica particles is commonly called silica dust. Activities such as cutting, grinding, sanding, drilling, loading or demolishing products that contain silica can generate respirable particles of crystalline silica dust that are small enough to breathe into your lungs. This dust may not be visible.
silica in the air and the build-up of dust on equipment and surfaces. Examples of controls include: exhaust ventilation and dust collec-tion systems, water sprays, wet drilling, enclosed cabs, and drill platform skirts. Prac-tice preventive maintenance because the extreme abrasiveness of the silica dust can damage the systems you install.
