Why is Silica Hazardous? - Silica Safe
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. The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain crystalline silica particles.
Crystalline Silica Exposure - Home | Occupational Safety ...
Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Quartz is the most common form of crystalline silica. Cristobalite and tridymite are two other forms of crystalline silica. All three forms may become respirable size particles when workers chip, cut, drill, or grind objects that contain crystalline silica.
