It can be released into the air when the rock or articles made from the rock are crushed, cut, or worked in some other way. 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 canc...
  • 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.
