In nature, quartz is the cr ystal line form most commonly encountered an d is so abu ndant that the term quartz is often used in place of the general term crystalline silica [6, 7] Quartz is abundant in most rocks and soils and is also present in sand, mortar, concrete, fluxes, abrasives, construction aggregate, porcelain, paints and brick .
Silica or silicon dioxide occurs in two forms, either crystalline or amorphous The most common type of crystalline silica, quartz, is found in most igneous, metamorphic and sedimentary rock The potential for worker exposure to crystalline silica is widespread within the minerals mining and quarrying industry.
Why is Silica Hazardous? Silica, often referred to as quartz, is a very common mineral It is found in many materials common on construction and oil & gas sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials.
Silica exposure is also associated with increased risk for lung infection (notably, tuberculosis), lung cancer, emphysema, autoimmune diseases, and kidney disease (1) Because quartz, a type of crystalline silica, is commonly found in stone, workers who cut, polish, or grind stone materials can be exposed to silica.
