Asbestos is a highly hazardous material that was commonly used in construction in the past. Asbestos is a naturally occurring mineral that was used in building materials, such as insulation, flooring, and roofing, among others. Since it is a fibrous mineral, it can easily break down into tiny airborne fibers that can be inhaled by humans. Once these fibers enter the lungs, they can cause life-threatening diseases, including lung cancer, mesothelioma, and asbestosis.

The use of asbestos has been banned in many countries, including the UK, since it poses health risks to people who inhale it. However, many buildings constructed before the ban may still contain asbestos. It is therefore essential to conduct an asbestos survey to identify any potential hazards.
