Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Quartz is the most common form of crystalline silica. Cristobalite and tridymite are two other forms of crystalline silica. All three forms may become respirable size particles when workers chip, cut, drill, or grind objects that contain crystalline silica.
Silica dust is dangerous.

high silica eruptions are generally explosive, giving rise to large abbounts of dust and may even result in pyroclastic flows. This happens because high silica melts are more viscous (thick) than low silica melts. If you see a nice river or fountain of lava, you can bet that it is relatively low in silica, probably a basalt.
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
One use according to Vexcon Exterminators is use of silica dust in pest control for wasps and other insects.Silica Gel has many uses. Silica Gel absorbs moisture from the air as well as anything with which it comes in contact. It is used to protect electronics, leather goods and dried food products from moisture. Silica Gel can also be used to preserve the freshness of vitamins, create professional looking dried flower arrangements, and save electronic devices that have gotten wet.
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.

Silicosis. Over time the exposure to silica dust in blocks can have irreparable effects on the lungs.
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.
Probably a miner who inhaled silica dust when he was mining for minerals.
No- but it does contain silica- and you should avoid breathing silica dust. The Hardie website has information on working safely with Hardiplank.
