Respirable Crystalline Silica - OSHWiki

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.
