Granite, sand, fill dirt, and top soil Asphaltcontaining rock or stone Abrasive used for blasting Silica is the most common hazard on a work site. Any activity that creates dust can expose workers to airborne silica. The most common ways to create silica dust are as follows: Chipping, sawing, grinding, hammering, or drilling
Crystalline silica is found in sand, stone, concrete and mortar. When workers cut, crush, drill, polish, saw or grind products containing silica, dust particles are generated that are small enough to lodge deep in the lungs and cause illness or disease including silicosis.
Silica Flour and Silica Fume Argonne National Laboratory. Hi Mark, Both materials are pure silica (silicon dioxide). Silica flour is simply made by grinding pure silica sand to a very fine powder.
