Safety and Health Topics | Respirable Crystalline …
Respirable crystalline silica – very small particles at least 100 times smaller than ordinary sand you might find on beaches and playgrounds – is created when cutting, sawing, grinding, drilling, and crushing stone, rock, concrete, brick, block, and mortar.
Silica - Respirable crystalline silica (RCS): Tackling ...
Silica is a natural substance found in most rocks, sand and clay and in products such as bricks and concrete. In the workplace these materials create dust when they are cut, sanded down etc. Some of this dust may be fine enough to reach deep inside the lung, this is known as respirable crystalline silica (RCS) and can cause harm to health.

23-6-2020 · The general industry standard requires employers to make medical surveillance available at no cost, and at a reasonable time and place, to any employee who will be occupationally exposed to respirable crystalline silica at or above the AL (or, before June 23, 2020, above the PEL) for 30 or more days a year. 29 C.F.R. § 1910.1053(i)(1)(i), (l)(4).
Respirable crystalline silica analysis | Malvern …
Controlling respirable crystalline silica to keep workplaces safe. Respirable crystalline silica is formed when a silica-containing material is mechanically treated, as the treatment causes the formation of dust consisting of tiny silica particles a few microns large.
Crystalline silica and silicosis | Safe Work Australia
Crystalline silica is found in sand, stone, concrete and mortar. When workers cut, crush, drill, polish, stone or grind products containing silica, dust particles are generated that are small enough to lodge deep in the lungs and cause illness or disease including silicosis.
RESPIRABLE CRYSTALLINE SILICA: THE FACTS
RESPIRABLE CRYSTALLINE SILICA WHAT IS IT? Crystalline silica is a natural substance found in stone, rocks, sand and clay, as well as products like bricks, tiles, concrete and some stone composites. When these materials are worked on, for example by cutting or drilling, the crystalline silica is released as a very fine dust which can be ...

Respirable Crystalline Silica - RCS | Safe Silica
Some of these particles are very fine – known as respirable crystalline silica or RCS. If high quantities of this very fine RCS dust are inhaled on a regular basis over many years, there is a potential risk that the cumulative effects can cause a lung disease known as silicosis , followed in severe cases by lung cancer.
