Asbestos is a naturally occurring mineral that was widely used in building materials in the past. It was popular because of its fire-resistant properties and strength. However, the use of asbestos was banned in the UK in 1999 because of its dangerous health risks. When asbestos is disturbed, it releases microscopic fibers into the air, which can cause serious health issues when inhaled. Asbestos exposure can lead to lung cancer, mesothelioma, and asbestosis.

The risk of exposure to asbestos can be higher in older buildings, homes, and workplaces, constructed before 2000. Asbestos can be found in various materials such as insulation, roofing, siding, flooring, ceiling tiles, and many more. Asbestos-containing materials in good condition are unlikely to pose a risk, but it is better to have them surveyed and eliminated if present.
