Crystalline silica is a common mineral found in naturally occurring and manmade materials that consists of very small particles. Exposure to respirable crystalline silica can occur during the manufacturing of glass, pottery, ceramics, brick, concrete and artificial stone, as well as during the use of industrial sand in operations or abrasive blasting with sand.
Silica is one of the most common hazards on a worksite, particularly in the construction, oil and gas, manufacturing, and agriculture industries. Silica dust can cause silicosis, a serious and irreversible lung disease. It can also cause lung cancer. Cutting, breaking, crushing, drilling, grinding, or blasting concrete or stone releases the dust.
Silica Sand is quartz that over time, through the work of water and wind, has been broken down into tiny granules. Commercial Silica Sand is widely used as a proppant by companies involved in oil and natural gas recovery in conventional and unconventional resource plays.

Whenever materials containing crystalline silica — masonry, brick, stone, concrete, glass — are sawn, drilled, chipped or crushed, silica dust is created and released. Silica sand is especially problematic because it is grainy and dusty, even in its natural state. Most particles are 100 times smaller than sand found on beaches. Silica Exposure
