Guideline For Assessing Stone Workers Exposed To Silica. 30 per cent silica, engineered stone can have silica concentrations of more than 90 per cent. Therefore it is critical that appropriate controls are in place to eliminate or minimise a worker's chance of inhaling respirable crystalline silica.
Silica is a natural substance found in varying amounts in most rocks, sand and clay. For example, sandstone contains more than 70% silica, whereas granite might contain 15-30%. Silica is also...
Most of the popular brands of engineered stone combine a large proportion ( 93 percent by weight, 66 percent by volume) of crushed quartz crystals with a binder of polyester resin.Does Engineering Stone Have Silica Silica occurs naturally in the earth, and it is a component of many construction and manufacturing materials.
Crystalline silica is a common mineral found in the earth's crust. Materials like sand, stone, concrete, and mortar contain crystalline silica. It is also used to make products such as glass, pottery, ceramics, bricks, and artificial stone.
We report here a case in which such a spiky stone, analysed by X-ray analysis and infra-red spectroscopy, turned out to consist almost entirely of silicon dioxide (silica). A likely source of the silica was identified, and possible implications of the case are discussed.

Engineered stone is also known as reconstituted stone. The amended OHS Regulations define 'engineered stone' as 'manufactured composite stone that contains resins and has a crystalline silica content of at least 80 per cent'. Engineered stone of this kind has been commonly used in kitchen, bathroom and laundry benchtops.
Engineering Control Of Silica Dust From Stone Unfortunately, a large amount of dust that contains crystalline silica can be produced during stone countertop fabrication and installation. On average, granite naturally contains 72% crystalline silica by weight Blatt and Tracy 1997, and engineered quartz stone contains about 90% quartz grains by mass in a polymer …

Silica Hazards from Engineered Stone Countertops Blogs . Most recently, 46 cases of silicosis were reported in Spain in workers cutting and installing engineered stone countertops with silica content of 70-90% (Pérez-Alonso et al. 2014). These individuals were young (ages 29–37 years) and worked in the industry for 9–17 years.

Silica dust is generated in workplace mechanical processes such as crushing, cutting, drilling, grinding, sawing or polishing of natural stone or man-made products that contain silica. Some dust particles can be so small that they are not visible; these are commonly referred to as respirable particles.
A new engineered stone countertop product known as "quartz surfacing," was created in the late 1980s by combining quartz aggregate with resins to create a product for use in home building and home improvement. Manufacturing of this material, including products such as CaesarStone™, Silestone™, Zodiaq™, or Cambria™ is a fast growing industry.
