Silica is a natural mineral found in many construction materials such as concrete and mortar. The silica is broken into very fine dust (also known as Respirable Crystalline Silica or RCS) during many common tasks such as cutting, drilling and grinding. Anyone who breathes in these dusts should know the damage they can do to the lungs and airways.
