[ 3] and reach deep into the lungs, potentially causing serious health issues. The exposure to silica dust produces lung diseases like silicosis and silico-tuberculosis. As workers cut, grind, drill, crush or otherwise alter these materials during construction work, they may be exposed to respirable, airborne silica particles. While the Federal NIOSH airborne limit for the very dangerous Crystalline Silica is only .05mg/m3, the IDLH on Amorphous Silica is a whopping 3000mg/m3, which is 60,000 times higher than Crystalline Silica. Materials like sand, stone, concrete and mortar contain crystalline silica. This occurs primarily on worksites involving cutting, sawing, drilling, or crushing silica. This means the internal structure is closer to glass, which has almost no internal crystalline structure, than to regular silica which has a well defined crystal structure. It is commonly called. . Silicosis, an irreversible but preventable lung disease, is caused by inhalation of respirable silica dust. There are non-crystalline and crystalline forms of silicon dioxide. As crystalline silica dust swarms from cutting, drilling, or blasting, small particles are . Silica damages the lung and causes scar tissue to form. Silica supplements may help strengthen bones, improve skin health and prevent thinning hair. Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. Silica can be found in most types of rock, in concrete and other construction materials, and even in some types of soil.

Crystalline silica is a common mineral found in the earth's crust. Search Blog. Workers are required to either wet the concrete to control the dust. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen. 1 the crystalline forms have been well investigated for their role in developing pulmonary silicosis, a lung pneumoconiosis characterized by alveolar proteinosis and diffuse fibrosis. Occupational exposure to crystalline silica dust is associated with an increased risk for pulmonary diseases such as silicosis, tuberculosis, chronic bronchitis, chronic obstructive pulmonary disease (COPD) and lung cancer. Crystalline silica is a basic component of the Earth's crust and can be detected in soil, sand, granite and many other minerals. Answer (1 of 2): This is actually a good question. The most at risk to develop these diseases are miners, construction workers, and oil & gas engineers that are often performing the tasks or processes that release the dangerous respirable crystalline silica dust. Silica exposure can also cause lung cancer. The producers of crystalline silica and products containing it adhere to the principles of product stewardship: they manage their products in a responsible way by minimising the health, safety, environmental, and social impacts of a product throughout all lifecycle stages. Silica Dust The fine dust is known as respirable crystalline silica (RCS) and is too fine to see with normal lighting. Non-crystalline silica is found in glass, silicon carbide, and silicone. Respirable crystalline silica dust particles are tiny, about 100 times smaller than the grains of sand found on the beach. Many industrial and commercial processes require crystalline silica.
