Asbestos is a naturally occurring mineral that was widely used in construction materials throughout the 20th century. It was a popular choice due to its fire-resistant, insulation and durability properties. Unfortunately, it was later discovered that asbestos fibres can lead to a number of serious health issues, and is now banned in many countries, including the UK.

When asbestos-containing materials are disturbed, the fibres can be released into the air, posing a serious health risk. These fibres are particularly dangerous when inhaled, as they can become lodged in the lungs, leading to a range of diseases including asbestosis, lung cancer, and mesothelioma.
