Silica dust is produced when materials containing silica such as natural or engineered stone, bricks, concrete or tiles are cut, drilled, polished or ground.
The dust particles are so small that you may not know you are breathing them in. Silica dust can lodge deep into your lungs and cause permanent serious diseases such as silicosis and lung cancer.
The information below is relevant to workers in all industries that can be exposed to silica dust, such as construction, mining and tunnelling.
