Asbestos is a mineral that was commonly used in construction materials such as insulation, ceiling tiles, and flooring in the 20th century. The material was valued for its durability, heat resistance, and fireproofing properties. However, asbestos has been proven to be a health hazard when the material is damaged or disturbed, releasing fibers into the air that can be inhaled.

The inhalation of asbestos fibers can lead to serious health problems such as lung cancer, mesothelioma, and asbestosis. Due to these health risks, the use of asbestos in construction materials has been banned in many countries, including the UK.
