Causes of silicosis
Silica dust is naturally found in many types of rock, sand and soil. When silica dust enters the lungs, it can irritate the lungs and cause inflammation. This eventually leads to scarring in the lungs – or pulmonary fibrosis.
Silicosis usually develops 10-20 years after exposure to silica dust, so you may not notice any symptoms until long after your exposure. People who are exposed at work are at higher risk of developing the condition. If your job involves cutting, chipping or grinding any kind of stone, you may breathe in silica dust. Industries at risk of silicosis include construction, mining, quarrying, demolition, sand blasting, stone masonry, worktop manufacturing and fitting, tiling, pottery, ceramics and glass.
