Asbestos is a hazardous substance that is commonly found in many properties built before the 1990s. It was used widely as a building material due to its insulating and fire-resistant properties. However, it is now known to cause serious health problems when its fibres are inhaled, such as lung cancer, mesothelioma, and asbestosis.

In the UK, it is illegal to use or import asbestos, and its disposal must be carried out by licensed and trained professionals who are equipped to handle and transport it safely. Asbestos waste is classified as hazardous waste, which means it must be disposed of following specific guidelines and regulations to minimise the risk of exposure to humans and the environment.
