One potential source of serious injury in grinding comes from an oversight that is easy to make operating the wheel in an over-speed condition While a wheel that is run far enough in excess of its rated maximum speed may shatter within minutes of operation danger may also result from a wheel run just slightly faster than its rated speed This less severe over-speed condition can cause the

Dust hub This site provides information to help employers control exposure to dust in the workplace You can also access further information on dust from this site Dust is tiny dry particles in the air and can be produced when materials are cut drilled demolished sanded shovelled etc This means many work activities can create dust Dust is not always an obvious health hazard as the

It is the fine fraction of the dust the respirable fraction that is harmful to health when inhaled Respirable crystalline silica is often abbreviated as RCS Exposure to RCS over many years is harmful to health causing silicosis and increasing the risk of lung cancer and other serious diseases amongst workers Restricting exposure to very low levels (around 0 05 mg/m 3 of RCS averaged

When using a handheld grinder use a model equipped with an integrated water delivery system that continuously feeds water to the grinding surface Use a grinder that is equipped with a commercially available shroud and dust collection system Operate and maintain the tool in accordance with the manufacturer's instructions to minimize dust emissions

Silica dust is created when a material containing crystalline silica is subjected to a mechanical process such as crushing grinding drilling cutting crushing or polishing The respirable crystalline silica released is 100 times smaller than a grain of sand meaning it may be inhaled unknowingly and can penetrate deep into the lungs Silica dust is 20 times more toxic than coal dust

What is Silica? Silica often referred to as quartz is a very common mineral Silica is a mineral that constitutes a major part of the earth's crust and is found in many types of rocks and soils Silica exists in a number of forms such as quartz glass or it may be combined with other elements to form silicates which are found in a large number of other rocks Silica or crystalline silica
