Crystalline silica is an important industrial material found abundantly in the earth’s crust. It is a mineral that occurs in several forms. Quartz, the most common form, is a component of sand, stone, rock, concrete, brick, block, and mortar. Many of these materials are used every day across a wide variety of industrial settings, including construction, mining, manufacturing, maritime, and agriculture.
Occupational exposure to crystalline silica often occurs as part of common workplace operations involving cutting, sawing, drilling, and crushing of concrete, brick, block, rock, and stone products (such as in construction work).
Operations using sand products (such as glass manufacturing, foundries, and sand blasting) can result in worker inhalation of small (respirable) crystalline silica particles from the air.
These types of exposures can lead to the development of disabling and sometimes fatal lung diseases, including silicosis and lung cancer. Processes historically associated with high rates of silicosis include sandblasting, sand-casting foundry operations, mining, tunneling, cement cutting and demolition, masonry work, and granite cutting.
