Silica is a mineral found in sand, rocks, and soil. Silica dust is produced during work processes such as digging and blasting, or grinding, drilling, or sawing silica-containing materials. Silica is used as an abrasive, insulator, and filler in a number of industries.
Silica causes a number of chronic diseases including lung cancer, silicosis (scarring of the lungs), and chronic obstructive pulmonary disease (COPD).
