What is crystalline silica?

Crystalline silica is a basic component of soil, sand, granite, and many other materials. 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.
