Respirable Crystalline Silica - RCS Safe Silica

Respirable crystalline silica (RCS) An avoidable risk in industrial workplaces, and no risk to the general public. In everyday contexts, crystalline silica is safe. It is inert, meaning that it does not react with any chemicals, and it is not harmful to health.

Respirable Crystalline Silica - OSHWiki

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 over each working day) will minimise the risk of harm.

Safe Work Procedure for Respirable Crystalline Silica

What is Crystalline Silica (a.k.a. Silica Dust)? Crystalline Silica is best known as Silica dust. You'll encounter it in many building and construction materials; including gravel, sand, stone, rock, concrete, tiles, bricks and even some plastics. It comes in a variety of forms, though the most common is quartz. Silica dust becomes a problem when released into the air, at which point we refer to it as "respirable crystalline silica" or RCS.
