These dusts are produced by casting sand, fettlings and kiln linings. Silica is actually a common naturally occurring element found in sand and quartz. When silica-containing rocks and minerals are blasted, chipped, cut, ground, and drilled, small particles are released into the air, which can then be breathed in and land in workers' lungs.

Silica sand (also commonly referred to as frac sand) is a crucial ingredient in the oil and natural gas extraction process known as fracking. The hydraulic fracturing ("fracking") process for oil and gas takes a mixture of proppant (usually frac sand), water, and chemicals and injects this mixture into a well under very high pressure.
