Asbestos is a naturally occurring fibrous mineral that was commonly used in construction materials, such as roof tiles, insulation, and cement, until its ban in 1999 in the UK. Asbestos was popular because of its insulating, fire-resistant, and durable properties. However, it was later discovered that asbestos exposure could lead to a range of serious health conditions, including asbestos-related lung cancer, asbestosis, and mesothelioma, a rare and deadly form of cancer.

Despite its ban, asbestos can still be found in many older buildings constructed before the ban, and those built up to the 1980s. This makes it important for property owners and managers to assess and manage the presence of asbestos in their buildings to ensure the safety of occupants.
