WHAT IS SILICA?
Silica is a natural substance found in varying amounts in most stones, rocks, sand and clay. These materials may contain large amounts of respirable crystalline silica (RCS), which can be fatal if particles are breathed in over time.
Silica particles are produced during many manufacturing tasks. Brick and tile manufacture and cutting, stone working and foundry work can all produce silica particles in the airborne dust which are too small to be seen. Regularly breathing in this dust over a long time can cause irreversible, life-changing lung diseases.
Even breathing in small amounts of silica dust puts you at risk of developing lung disease.
