What Is Silica and How Can it Support Your Health?
Crystalline silica is found in rock, brick, and concrete. Grinding, sawing, crushing, or drilling these materials produces a fine powder that causes serious respiratory concerns. It is possible for homes to retain this sort of dust after a construction or remodeling project but, most of the time, unless you work on a construction site or quarry, you probably don’t have to worry about

Crystalline silica and silicosis | Safe Work Australia
Crystalline silica (silica) is found in sand, stone, concrete and mortar. It is also used to make a variety of products including composite stone used to fabricate kitchen and bathroom benchtops, bricks, tiles and some plastics. When workers cut, crush, drill, polish, saw or grind products that contain silica, dust particles are generated that are small enough to lodge deep in the lungs and

Dust containing crystalline silica in construction work
Exposure to crystalline silica can occur during common construction and demolition tasks when working with concrete, bricks, mortar, tiles, stone or other masonry. If employees regularly dry cut, grind, crush, drill, sweep or demolish these materials without engineering controls in place, it is likely that the exposure standard will be exceeded.
