BLACK BEAUTY® blasting abrasives are a preferred alternative to silica sand. Silica sand can contain up to 99% free silica which has been found to cause silicosis, a sometimes fatal lung disease. BLACK BEAUTY® abrasives are low dusting, chemically inert, contain less than 0.1% free silica, and are not causally linked with any disease ...
TARGET ® Silica Abrasives are high quality, close graded silica sands which are produced at our Morinville, Alberta, plant in ten size grades. Typical gradations are presented in the following tables. USES TARGET Silica Abrasives are suitable for all applications requiring a high quality, clean, well graded sand. Typical uses include:
Mohs' Hardness (Typical) of Abrasives table from READE. Abrasive blasting for surface preparation is an important step in providing a foundation for protective coatings. For years, tests have concluded that high-performance coatings provide excellent corrosion protection and durability when applied over a blast-cleaned surface with a consistent anchor profile.
Silica sand may also be known as silica sand abrasive when used for abrasive blasting. Corrosionpedia explains Silica Sand Silica sand is used for a variety of industrial applications depending on the grain size, refractories, texture and shape of the sample to be used.
Sand Express BLASTSAND is an economical and efficient abrasive sand. The angular silica sand is suitable for the removal of paint and rust from steel and concrete surfaces. BLASTSAND is available with DUSTNET® - dust supplement designed to reduce nuisance and respirable dust.

Blasting Abrasive [Silica Sand] Silica Sand Emmett Granusil fillers and aggregates are whole-grain, crystalline silica of superior hardness and uniformity. All grades are washed, dried and screened under rigid SPC quality assurance controls. The result is chemical purity, minimal clay and particulate iron, and consistent particle size distribution.

Silica sand should not be used as an abrasive blasting material. See OSHA standard PB-246-697 and "OSHA Crystalline Silica Exposure" Health Hazard Information in the Safety section of our website. All of Clemtex's Abrasives sold abide by OSHA's standards and contain less than 1% free silica.
Provision 29 CFR 1910.94(a)(5)(ii)(b) of the ventilation standard requires that "abrasive-blasting respirators" shall be worn by all abrasive-blasting operators when using silica sand in manual blasting operations where the nozzle and blast are not physically separated from the operator in an exhaust ventilated enclosure.
In 1974, the United States was poised to adopt a ban on silica sand for abrasive blasting on the recommendation of the National Institute for Occupational Safety and Health (NIOSH), but as discussed in our article on the Silica Rule, political forces hampered adoption, and wet abrasive blasting technology failed to find a foothold in North America.
Silicosis in Sandblasters Use Silica Substitutes. Division of Epidemiology, Environmental and Occupational Health. ... the risk of silicosis to this segment of the work population is by substituting a less toxic material for silica sand during abrasive blasting operations.
Abrasive blasting uses compressed air or water to direct a high velocity stream of an abrasive material to clean an object or surface, remove burrs, apply a texture or prepare a surface for painting. Abrasive blasting is more commonly known as sandblasting since silica sand is commonly used as the ...
Further, the language is that of a design standard; that is, a continuous flow, supplied-air respirator (presumably Type CE) is required without regard to the silica dust concentration (and without the need to demonstrate an exposure above the permissible exposure limit for silica-containing dust) where silica sand is the abrasive and the ...
Silica Sand & Sandblasting: Risks & Safety Suggestions. ... Risks of Silica Sand. Silica sand is a very abrasive material making it effective at quickly profiling a product surface but the problem is that when it hits a products surface it fractures into very tiny particles.
Abrasive blasting is the use of abrasive material to clean or texturize a material such as metal or masonry. Sand is the most widely used blasting abrasive. ... Worker exposure to free crystalline silica is of concern when silica sand is used for abrasive blasting. Coal and smelter slags are commonly used for abrasive blasting at shipyards.
The silica sand used in abrasive blasting typically fractures into fine particles and becomes airborne (see Figure 1). Inhalation of such silica appears to produce a more severe lung reaction than silica that is not freshly fractured [Vallyathan et al. 1988].
