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. The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain crystalline silica particles.
