Hydraulic fracturing (also called fracking, fracing, hydrofracking, fraccing, frac'ing, and hydrofracturing) is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of 'fracking fluid' (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore ...
Fracking sand (or frac sand) refers to sand and similar small materials used during the process of hydraulic fracturing. Fracking is a method for extracting underground oil …
According to the National Institute for Occupational Safety and Health (NIOSH), workers may be exposed to dust containing high levels of respirable crystalline silica (silica) during hydraulic fracturing ("fracking"). Silica is a common mineral found in the earth's crust and is a major component of the sand, clay and stone materials used to make everyday products such as concrete, brick ...
Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses. The specifications for each use vary, but silica resources for most uses are

Jul 17, 2013· NIOSH-Designed Technology Can Reduce Workers' Exposure to Silica at Hydraulic Fracturing Sites NIOSH Update (Nov 2015) Researchers have developed and tested a prototype called the "mini-baghouse" that can protect oil and gas extraction workers by effectively controlling silica dust at hydraulic fracturing worksites.
Minnesota is not currently fracking for oil and gas, however some sand used for hydraulic fracturing is mined and processed in Minnesota. Most of the silica sand in Minnesota is found in the Minnesota River Valley and southeastern Minnesota. Industrial silica sand is also being mined from sandstone areas in Wisconsin, Iowa, and Illinois.
Crystalline Silica IN AIR & WATER, AND HEALTH EFFECTS Crystalline silica is a type of silica formed from silica sand, a 'building block' material in rock, soil and sand, through natural heat and pressure. It is used in a number of industrial and commercial processes like glass-making, road-building, hydraulic fracturing for oil and gas
Mar 20, 2017· Learn more about workplace solutions for controlling exposures to Respirable Crystalline Silica in construction and hydraulic fracturing. Save lives and prevent new cases of silicosis, a severe lung disease. Understand the occupational exposure limits to keep workers safe from breathing hazardous silica dust.
U.S. SILICA COMPANY Safety Data Sheet Silica Sand, Ground Silica and Fine Ground Silica Page 4 of 10 Appropriate engineering controls: Use adequate general or local exhaust ventilation to maintain concentrations in the workplace below the applicable exposure limits listed above.
Jul 31, 2013· Falls Church, VA – Oil and gas workers are exposed to respirable crystalline silica during directional drilling and hydraulic fracturing operations, a new NIOSH study concludes. Induced hydraulic fracturing, also known as "fracking," is the process in which large amounts of water, sand and chemicals are injected at high pressure into a well opening to force gas or oil to flow out.
Employee exposure to silica dust generation during hydraulic fracturing operations is a continuing concern for the oil and gas industry. Energy and production (E&P) companies face ongoing scrutiny of the impact of hydraulic fracturing operations on air quality.
A single well requires the use of millions of gallons of water and tons of sand. Air sampling results show that the majority of silica levels at hydraulic fracturing sites were above the Occupational Safety and Health Administration allowable standard and 84% were above Occupational Safety and Health Administration's new proposed standard.
Jun 14, 2018· OSHA's new standard limiting respirable silica exposure goes into effect for all industries on June 23, 2018. The new standard reduces the permissible exposure limit for respirable crystalline silica from 100 micrograms per cubic meter of air for general industry and 250 micrograms for the construction industry.
Feb 16, 2017· HYDRAULIC FRACTURING SILICA EXPOSURE. Feb 16, 2017. Hydraulic fracturing ("fracking") is a process used to extract oil and gas by high-pressure fracturing of rock or shale. Exposure to respirable crystalline silica is a major hazard in this industry. Massive amounts of sand are used in the process, and silica exposure is a constant issue.

As noted in the alert, respirable silica is a hazard common to many industries and industrial processes. Because large quantities of silica sand are used during hydraulic fracturing, NIOSH began a cooperative effort in January 2010 to collect data regarding silica exposure at hydraulic fracturing …
The value of silica sand can be significantly higher than sand and gravel used in the construction industry. Silica sand is processed into frac sand, a product used by the oil and gas industry. What type of industries use silica sand? Silica sand has been mined in the Upper Midwest for over a century.
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.
