It only takes a very small amount of respirable silica dust to create a health hazard. One of the dangerous effects of silica exposure is a disease called silicosis, which can be contracted after just a few months of high exposure. Silicosis occurs when silica dust enters the lungs and causes the formation of scar tissue, reducing the lungs ...

Description. Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2 ). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.

In the UK, there is an almost total reliance ...
Download a free copy (PDF) This leaflet explains what employers and employees should do to prevent lung disease caused by exposure to silica at work. Silica is a natural substance found in most rocks, sand and clay and in products such as bricks and concrete. In the workplace these materials create dust when they are cut, sanded, carved etc.
Because quartz, a type of crystalline silica, is commonly found in stone, workers who cut, polish, or grind stone materials can be exposed to silica dust. Recently, silicosis outbreaks have been reported in several countries among workers who cut and finish stone slabs for countertops, a process known as stone fabrication ( 2 – 5 ).
Colloidal silica is used in many applications including catalysis, pharmaceuticals, and coatings. Although naturally formed silica materials are widely available, they are often in forms that are difficult to process or are even harmful to health. Therefore, uniform colloidal silicas are generally manufactured using synthetic chemical …
