Industrial sand used in certain operations such as foundry work and hydraulic fracturing (fracking) is also a source of respirable crystalline silica exposure Health Effects Crystalline forms of silica (quartz cristobalite and tridymite) that become airborne as dust with particle sizes of 10 microns and smaller are considered respirable Silica sand a natural raw material is an important component in the production of recyclable glass containers—a core element of the G3 commitment to sustainability The sand is also used for top dressing and bunker sand in golf courses bedding in horse arenas and surfaces in community parks

Noise and Silica Exposures

Noise and silica exposures are presented by quarry type in Table 2 For basalt excavation and portable crusher plants mean noise exposures exceeded the hearing protection program level indicating a need for a plant-wide hearing protection program For sand and gravel operations full shift exposures measured with the PEL and hearing protection

Silica Sand is actually a granular material It contains quartz and minute amounts of coal clay Sometimes it has minerals in it People call it quartz sand too Most importantly it is the industrial sand Quartz over time turns into Silica sand gradually because of

An unknown number of silica sand mines produce silica sand for construction and agricultural uses Silica sand mines producing frac sand may or may not process the sand on-site Off-site processing plants that receive silica sand from various mining operations in Minnesota and Wisconsin are also found in Minnesota How is it mined?

Delivering and handling the sand on site can lead to generation of fugitive dust and respirable crystalline silica Equipment relying on pneumatic handling of the sand creates the highest concentrations of dust and silica Data 1 exists demonstrating employee exposures to dust and silica above the current and future Permissible Exposure Limit

Blasting with silica sands such as beach sand river sand and any other crystalline silica sand may cause serious injury or be fatal Crystalline silica is recognized world-wide as a Class 1 Carcinogen The silica sand type abrasive media when used in abrasive blasting typically fractures into fine particles and becomes airborne

Silica Sand is actually a granular material It contains quartz and minute amounts of coal clay Sometimes it has minerals in it People call it quartz sand too Most importantly it is the industrial sand Quartz over time turns into Silica sand gradually because of

In almost all cases silica mining uses open pit or dredging mining methods with standard mining equipment Except for temporarily disturbing the immediate area while mining operations are active sand and gravel mining usually has limited environmental impact

Because sand has a negligible degree of porosity it has an extremely low specific surface area in the range from 40 to 160 cm 2 / g The material usually contains more than 99 7% SiO 2 with absorbed water being at a negligible level (0 1%) Ground silica sand is produced in a similar manner except that pulverizing is included

Exposure Risks for Silica Dust Silica dust is inhaled into the lungs where it is implicated in lung cancer as well as chronic bronchitis and other respiratory diseases As the substance makes its way from the lungs through the body silica can also damage other bodily systems most notably the
