What is respirable crystalline silica?
Crystalline silica is found in sand or quartz and is often used in a variety of building materials, such as concrete, tile, brick, countertops, glass, and more.
Many common workplace activities,such as cutting, grinding, drilling, sawing, and polishing produce fine dust that contains respirable crystalline silica.
The word “respirable” is what makes it so dangerous.
The crystalline silica particles are tiny—smaller than the diameter of a single human hair—and cannot be seen with the naked eye.
When they become airborne, they can enter the lungs and cause a serious and deadly condition known as silicosis.
