Asbestos is a naturally occurring mineral that was commonly used in building materials in the UK up until the late 1990s. It was used for its heat-resistant properties, as well as for its strength and durability. However, asbestos is now known to be a dangerous material that can cause serious health problems if it is not handled correctly.

When asbestos-containing materials are disturbed or damaged, they can release tiny fibres into the air that can be breathed in. These fibres can get stuck in the lungs and cause a range of respiratory problems, including lung cancer and mesothelioma.
