Asbestos is a naturally occurring mineral that was widely used in building materials, including insulation, roofing, and cement boards. It was a popular choice because of its durability, heat-resistance, and fire-proofing capabilities. However, it was later discovered that exposure to asbestos can cause severe health issues, including lung cancer, mesothelioma, and asbestosis.

The United Kingdom has banned the use of asbestos since 1999, but many older buildings still contain asbestos-containing materials. If you suspect that your building has asbestos, it's imperative to have it removed immediately to ensure the safety of yourself and others.
