Silicosis is a long-term, incurable lung disease that is caused when fine particles of silica enter a person’s lungs.

Crystallised silica can be found in types of stone, clay, sand and rock, and is spread into the air when the materials are cut, ground or split.

Exposure can lead to a persistent cough, shortness of breath, weakness and tiredness, respiratory failure and death.

Stonemasons, stone cutters, construction, demolition, worktop manufacturing and fitting, pottery, glass mining and sandblasting workers are considered at risk of coming into contact with high-silica products.
