To ask the Secretary of State for Work and Pensions, what data her Department holds on the groups most vulnerable to silicosis.

Evidence from a body of epidemiological research shows that the risk of silicosis increases according to the extent of exposure to respirable crystalline silica. Groups most vulnerable to developing silicosis are those with the highest exposures. A range of sources of evidence – including reports of silicosis cases from chest physicians, cases assessed for Industrial Injuries Disablement Benefit, and epidemiological studies – have identified specific worker groups that are at likely to be at highest risk. These include: quarrying; slate works; foundries; potteries; brick and tile making; stonemasonry; construction work involving cutting or breaking stone, concrete or brick; abrasive blasting and tunnelling; and industries that use silica flour to manufacture goods.
