The risk of exposure to silica dust from a task is assessed by examining the work processes involving silica or silica containing products. The assessment must consider the dust exposure that could occur. Having airborne dust levels monitored is the most accurate way to assess the risk. However, in some cases the risk may be clear without monitoring (e.g. where there are visible clouds of dust

Crystalline silica is harmful when respirable-sized dust of less than 10 microns is breathed deep into the lungs, as this can cause lung scarring known as silicosis. The lungs become less flexible, making it difficult to breathe and do hard work. The fibrosis of the lungs and the associated inflammation may lead to lung cancer.
