Silica exposure is a well-known danger for workers in mining and construction. With the spread of frac sand mining, however, silica air pollution has also become a danger for residents near sand mining and processing operations. Children, older adults and people with respiratory diseases are especially at risk.
Because of work-exposure to silica dust, silicosis is an occupational hazard to mining, sandblasting, quarry, ceramics and foundry workers, as well as grinders, stone cutters, stone countertops, refractory brick workers, tombstone workers, workers in the oil and gas industry, pottery workers, fiberglass manufacturing, glass manufacturing, flint ...
OSHA's Crystalline Silica Rule: General Industry and Maritime. OSHA is issuing two standards to protect workers from exposure to respirable . crystalline silica — one for general industry and maritime, and the other for construction — in order to allow employers to tailor solutions to the specific conditions in their workplaces.
This Hazard Alert focuses on countertop industry worker exposures to airborne silica dust, including . from quartz in stone. It covers the health effects of breathing silica dust, recommends ways to protect workers, and describes how OSHA and NIOSH can help employers effectively reduce silica dust exposures. Employers must ensure that workers are

Silica sand is also normally required to be well-sorted, i.e. to have grains of an approximately uniform size. Most sources of sand used by the construction industry do not satisfy these requirements and are not, therefore, suitable for glassmaking. Industrial uses of silica sand depend on its purity and physical characteristics. Some of the
The current size of the sand mining market in the United States is slightly over a billion dollars per year. The industry has been growing by nearly 10% annually since 2005 because of its use in hydrocarbon extraction. The majority of the market size for mining is held by Texas and Illinois.
It's also used by the oil and gas industries as a proppant to keep a hydraulic fracture from closing. A fine form of silica sand is also used as a filler for rubber, paints and plastics. When mining silica sand, the sand is put through an industrial screener that screens at a specific diameter.
