Breathing in silica dust can also cause silicosis: a debilitating, incurable, and sometimes fatal condition resulting from the development of scar tissue in the lungs. This is over an 8 hour shift. Crystalline silica can form a dust fine enough to penetrate deep into the lungs during the process of cutting, sanding, drilling or grinding. There is no cure for silicosis. It's extremely useful for industrial and manufacturing purposes because it's hard, chemically inert, and has a high melting point. Silicosis, an irreversible but preventable lung disease, is caused by inhalation of respirable silica dust. When inhaled, respirable silica dust enters the lungs and causes the formation of scar tissue, which reduces the lungs' ability to take in oxygen. As a result of silica exposure, chronic lung damage occurs. What is crystalline silica? Silica dust ranges in size and is characterized by its jagged crystalline form.
