The Control of Substances Hazardous to Health 1999 reg 4(1) specifically prohibits the use of sand and any other substances which contains silica for any blasting
Silica Sand. Silica sand is the original blasting abrasive, but is no longer recommended for blasting applications due to the occupational hazard silicosis. It is included here for comparative purposes only. ... plastics and fiberglass. Considered a less-hazardous alternative to
In the past, blast cleaning operations were done with silica sand. The term sandblasting originates from those days.Nowadays, it's clear that exposure to respirable crystalline silica during sandblasting can cause a serious or even fatal respiratory disease, called Silicosis, a scarring and hardening of the lungs. In most countries, it is now forbidden to use abrasives which contain more than ...
Sep 29, 2017 Sandblasting is a process that's typically used to remove paint or inscribe messages on stone. High speed particles of grit (formerly sand) are blasted at a surface, and the grit then grinds away the surface material. A number of alternatives to sandblasting exist, and many of them are a great deal more environmentally friendly.
My VFT/Sarr mix is 2 peat, 1 silica sand, and 1 Turface. I use it all by itself for Pings. I even us it for non-CPs, mainly succulents. For Lithops and the like I use it 50/50 with crushed granite. For things like Jade plants I use it with equal parts crushed granite and fine fir

As alternatives to quartz sand, Olivin sand is a widely used abrasive. Olivin sand comes mostly from Norway and contains less than 1% quartz. Blast with olivin sand create still dust, but this is not silica dust. The lungs are able to seperate the dust. Of course the use of a proper mask is still advised. Garnet. Garnet is a proper alternative.

Nov 11, 2019 This transformation eliminates “free silica” and cannot pulverize to particle sizes on the same level as silica in the naturally occurring crystalline state. In fact - NIOSH (The National Institute for Occupational Safety and Health (NIOSH), recommends glass bead as an alternative to silica sand.
Dustless blasting uses recycled bottle glass – zero free silica, no heat, no dust plume, and is harmless to humans and plant life. A whole lot less messy too! There is no faster, safer or more effective auto sandblasting alternative!
Oct 07, 2017 Options to silica sand are multiple and don't have to be soda blasting (which would not provide best anchor pattern for your paint anyway). There are all sorts of sanblasting media which one would call "sand
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

Jan 18, 2016 Since the 1950s, the use of sand in blasting has been illegal. Free silica blasting was found to be extremely harmful to the human respiratory system, forcing companies to find other materials to use in the blasting process. Despite all of this, people still refer to blasting services as “sandblasting

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 diseases, including silicosis.
Non- silica substitutes have been around for decades. Forty years ago, European nations banned the use of silica sand as an abrasive media and those nations have been using non-silica abrasives successfully ever since. All the steps necessary to develop a complete silica health and safety program overwhelm many abrasive blasting shop owners.
Silica sand has traditionally been one of the most commonly used blasting media. However, when silica sand impacts the blasted surface at high speeds, the grains of sand fracture and create copious dust and respirable crystalline silica. Using an alternative blasting medium can help reduce worker exposure to silica and other hazardous substances.
Dustless blasting uses recycled bottle glass – zero free silica, no heat, no dust plume, and is harmless to humans and plant life. A whole lot less messy too! There is no faster, safer or more effective auto sandblasting alternative!
Garnet – Blasting Media. Garnet is a more abrasive blasting media that can be used in sandblasting.It is an environmentally friendly alternative to many other blasting medias. Made from Andradite or Almandine deposits, garnet comes in a variety of sizes for use. It is also available either with smooth or rough edges, which changes the finish when used.
Recycled bottle glass is chemically known as Amorphous Silica, which means it contains less than 1% free-silica. Free-silica is commonly found in traditional blasting sand and other hard abrasive sandblasting media. Silica-sand dust in its natural state has an “open” crystalline structure that has the capability of sticking to lung tissues.
Nov 18, 2020 In 1950, in Great Britain use of silica sand for abrasive blasting was banned (Industries Act), followed by the Netherlands in 1956 and Belgium in 1964 (Council of Europe, 1970). Sandblasting is banned in India also as in the rest of the world. The ban on silica as an abrasive material has sparked research into alternative materials that ...
Silica sand is banned and it therefore cannot be used for sandblasting purposes in some countries. The media also causes corrosion on the sides of a blast gun which leads to faster wearing and tearing of machinery.The use of silica for abrasive blasting is also not economical since the media can only be used once or twice.

Sand contains a high percentage of silica, which if inhaled, can cause permanent respiratory damage to anyone exposed to it.
Staurolite, a dark coloured mineral that is a silicate of aluminium and iron, has some free silica content but much less than silica sand. It is marketed in the USA, where it naturally occurs, as an alternative to silica sand, in Europe, olivine, which is quarried in Norway, is marketed as silica free sand. It is a silicate if iron and magnesium.
Because Coal slag products are recycled, their production don’t impact our environment like mined sources of competing products like garnet or sand.
