Saturated Silica Gel can be reactivated by placing it in an oven at 150°C (300°F) for up to 3 ½ hours or until the blue color is restored; note: heating above 162°C (325°F) can damage the gel and render it unable to absorb moisture. Silica Dust will float in the air for up to 12 days, give or take. The particles are very tiny. One spec of silica dust is almost 100 times smaller than a single grain of sand. Due to its size, silica dust stays suspended in the air longer than other dust particles. The R.S.E. was 0.95, 0.94, and 0.81 for lung cancer, COPD, and silicosis, which indicates that silicosis's effect (risk ratio) on the mortality from these respiratory diseases in never-smokers was relatively stronger than the smokers. Unfortunately, the damage to the lungs cannot be reversed. But treatments such as inhalers and oxygen therapy can improve breathing and your quality of life. Your doctor might also suggest you stop smoking (if you smoke), have regular tests to check for tuberculosis (T.B.), and have the annual flu jab.
Crystalline silica is found in concrete, masonry, and rock materials. When these materials are made into a speck of fine dust and suspended in the air, breathing in these fine particles can produce lung damage. Silicosis can be disabling and may lead to death. Fly ash is an environmental hazard worldwide, containing organic pollutants, probable toxic metals like Se, As, B, V, Al, Pb, Hg, and Cr, and radionuclides Uranium and Thorium. Although fly ash contains toxic substances, it contains most oxides and trace elements.
