What is silica and how do I get exposed?

Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Quartz is the most common form of crystalline silica. Exposure occurs through inhalation of respirable particles created when silica-containing materials are manipulated. Activities such as chipping, cutting, cutting, drilling, blasting, and grinding of silica-containing materials are expected to produce respirable particles.
