Inhaling silica particles generated during cutting, sawing, grinding, drilling, and crushing materials such as stone, rock, concrete, brick, block and mortar can cause negative health consequences including silicosis, an incurable lung disease, lung cancer, and chronic obstructive pulmonary disease.
Reducing Silica Exposure in Concrete Cutting Part 1 Crystalline silica, a common mineral often produced on construction sites from materials like sand, stone, brick, mortar, and most commonly, concrete, poses a significant health risk to construction professionals.
Silica is a chemical compound commonly found in sand, stone, concrete, brick, mortar and other materials. When left undisturbed, silica does not present a hazard. However, once disturbed (through activities such as concrete cutting or sandblasting) the silica becomes a fine, easily inhaled dust that is hazardous if inhaled.
