Though it may be a cause for chronic Bronchitis, I'm sure one doesn't get it that quick.
Coal dust, silica dust, and asbestos, which may lead to pulmonary fibrosis
Silica is sand dust.
I'm protecting myself from inhaling the silica dust.
You can analyse crystalline silica respirable dust on a 37 mm 10 micron filter by sampling.
siliaca is an element and makes up most of the earths mantle. also is use in quarts witch is use in glass. also the more silica lava has the thicker and lighter it is.it can also be used in a rubber o-ring lubracant or any lubracant Silica is silicon dioxide with the formula SiO2 and is a crystal with a tetrahedral structure. Silica is formed when silicon is exposed to the oxygen in air. When found in nature, it's most commonly in sand and quartz. Silica is known for its hardness and is used in many things: glass, optical fibers in telecommunications, ceramics, microelectronics as an electronic insulator (because of its high chemical stability), cosmetics for its light-diffusing properties, pharmaceuticals, toothpaste as an abrasive, and as a gel used in aeronautics. Exposure to fine silica dust over a long period of time can be detrimental to health because the dust can lodge itself into the lungs and cause irritation. Eventually, it could cause silicosis, bronchitis, or cancer.
Silica dust is dangerous.
dust go ing inside your eyes

Silicosis. Over time the exposure to silica dust in blocks can have irreparable effects on the lungs.
Silicon is not known to be toxic, but if breathed in as a fine silica/silicate dust it may cause chronic respiratory problems, even it can cause lung cancer if directly breathed in. Silicates such as asbestos are carcinogenic.
YES! - Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Crystalline silica has been classified as a human lung carcinogen. Additionally, breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. The respirable silica dust enters the lungs and causes the formation of scar tissue, thus reducing the lungs' ability to take in oxygen. There is no cure for silicosis. Since silicosis affects lung function, it makes one more susceptible to lung infections like tuberculosis. REF: http://www.osha.gov/OshDoc/data_General_Facts/crystalline-factsheet.pdf
A major problem in geothermal power plants, where the silica dust comes up along with the steam. Very corrosive by sand blasting. A cyclone is one trick to separate dust and vapour.
