Crystalline silica is a mineral commonly found in natural materials like sand, rock and stone. It can also be found in man-made materials like concrete, tile, brick and mortar. When workers cut or drill into materials that contain silica, tiny dust particles are created. (The technical name for this dust is respirable crystalline silica).
Silica effects Generally, silica grades that are used as flow and anti-caking agents have very fine particles. They ensure that powders can flow evenly and do not clump together. As opposed to this, carrier silica types are used to absorb liquids and make them powdery. These are usually made from coarse, free flowing particles.

Employees who work around silica should wash their hands and face, and change into clean clothes before leaving the worksite. Work clothing should be washed in hot water with a heavy-duty laundry detergent before being used again. When washing these clothes at home, always keep them separate from other family laundry.
2 · The high amount of silica means that there is a very high risk of workers developing breathing problems and silicosis if they breathe in dust made from these products. An increase in the number of workers diagnosed with silicosis and progressive massive fibrosis has been linked to working with engineered stone.
