Asbestos is a natural mineral that was commonly used in construction materials such as insulation, roofing, and flooring. Asbestos materials are hazardous when disturbed, as they release microscopic fibers into the air, which can be inhaled and cause long-term health problems, such as mesothelioma, lung cancer, and asbestosis. Asbestos was banned in the UK in 1999, but many buildings constructed before this date still contain asbestos, which is why it is important to have it safely removed by a professional asbestos abatement company.
