According to WCF Insurance’s page on silica safety, crystalline silica is a naturally occurring mineral commonly found in sand, rock, concrete, glass, marble, brick, mortar, porcelain, ceramic, artificial rock, and many other products that exists in three main forms: quartz (most common), crystobalite, and tridymite. When inhaled, silica can cause serious problems. Silicosis and lung disease are a couple of the most common health conditions associated with exposure to silica. Exposure may also increase the risk of kidney disease and lung cancer. To help reduce workers’ exposure to crystalline silica, the National Institute for Occupational Safety and Health (NIOSH) has made the following recommendations:

*   Maintain dust control systems to make sure they are functioning properly.
*   Wear disposable or washable protective clothing.
