Inhalation exposure to airborne respirable crystalline silica (RCS) poses major health risks in many industrial environments.Introduction. Crystalline silica is the name for a group of naturally occurring minerals found in many types of rock. It can be released into the air when the rock or articles made from the rock are crushed, cut, or worked in some other way. It is the fine fraction of the dust, the respirable fraction, that is harmful to health when inhaled.Respirable Crystalline Silica OSHwiki European Agency for

to take steps to protect workers from exposure to respirable crystalline silica. What is Respirable Crystalline Silica? Crystalline silica is a common mineral that is found in construction materials such as sand, stone, concrete, brick, and mortar. When workers cut, grind, drill, or crush materials that contain crystalline silica, very smallCrystalline silica is harmful when respirable-sized dust of less than 10 microns is breathed deep into the lungs, as this can cause lung scarring known as silicosis. The lungs become less flexible, making it difficult to breathe and do hard work. The fibrosis of the lungs and the associated inflammation may lead to lung cancer.Respirable crystalline silica SafeWork SA

Respirable crystalline silica dust. Silica is a natural substance found in concrete, bricks, rocks, stone (including artificial or engineered stone found in composite kitchen benchtops), sand and clay. RCS dust is created when materials containing silica are cut, ground, drilled, sanded, polished or otherwise disturbed.Occupational exposure to respirable crystalline silica (silica hereafter) occurs in tens of millions of workers globally in a wide range of industries, including construction, mining, and quarrying, as well as manufacturing of bricks, ceramics, and metal products (1, 2).Silica is classified as a human lung carcinogen by the International Respirable Crystalline Silica Exposure, Smoking, and Lung
