A video discussing a field-based approach to silica monitoring. Monitoring could help reduce exposure to silica. Using the Hierarchy of Controls, there are various methods of preventing exposure to respirable crystalline silica. The best way to prevent silicosis is to avoid worker exposure to dust containing respirable crystalline silica. [24]
Respirable crystalline silica – microscopic particles of silica can be become airborne and inhaled when cutting, sawing, grinding, or drilling rock or concrete. Silica is used for foundry molds and cores, so exposure can occur when grinding on castings. Fracking uses silica. About 2.3 million individuals in the U.S. are exposed to silica at work.
Crystalline silica is an occupational hazard for those working with stone countertops because the process of cutting and installing the countertops creates large amounts of airborne silica. [75] Crystalline silica used in hydraulic fracturing presents a health hazard to workers. [34]
Silicosis (also known as "grinder's disease" or Potter's rot) – crystalline silica dust; Bauxite fibrosis – bauxite; Berylliosis – beryllium; Siderosis – iron; Byssinosis – Byssinosis is caused by cotton dust inhalation and typically demonstrates a different pattern of lung abnormalities from most other pneumoconiosis.

Florenza Marble & Granite exposed employees to silica levels up to six times greater than permissible, leaving a 31-year worker, his 59-year-old father and a co-worker with silicosis, an incurable ...
Burned residential areas may contain silica dust, asbestos, metals, or polyaromatic hydrocarbons. Additional health hazards of fire debris cleanup work may include carbon monoxide and hazardous liquids [2] Silica, or silicon dioxide, can occur in a crystalline or noncrystalline (amorphous) form. In fire debris, silica can be found in concrete ...
However, magmas containing less than 58% SiO 2 are thought to be unlikely to contain crystalline silica. [32] The exposure levels to free crystalline silica in the ash are commonly used to characterise the risk of silicosis in occupational studies (for people who work in mining, construction and other industries,) because it is classified as a ...
Kaolin products may also contain traces of crystalline silica, a known carcinogen if inhaled. [84] In the US, the Occupational Safety and Health Administration (OSHA) has set the legal limit (permissible exposure limit) for kaolin exposure in the workplace as 15 mg/m 3 total exposure and 5 mg/m 3 respiratory
