Silica dust (crystalline silica) is found in some stone, rock, sand, gravel and clay. The most common form is quartz. Silica dust can also be found in the following products: bricks; tiles; concrete; some plastic material. When these materials are worked on, silica is released as a fine dust known as respirable crystalline silica or silica dust.
