Introduction Crystalline silica is the name for a group of naturally occurring minerals found in many types of rock. It can be released into the air when the rock or articles made from the rock are crushed, cut, or worked in some other way. It is the fine fraction of the dust, the respirable fraction, that is harmful to health when inhaled.
