Asbestos is a naturally occurring mineral that was extensively used in building and construction materials in the UK during the 20th century. It was primarily used for properties' insulation, fireproofing, and strength, which makes it an obvious choice for many builders and contractors.

However, over time, research revealed that exposure to asbestos can lead to serious health problems, including lung cancer, mesothelioma, and asbestosis. Asbestos is responsible for over 5,000 deaths in the UK each year, making it a serious concern for public health.

Despite the dangers of asbestos exposure, many buildings constructed before the late 1990s still contain asbestos-containing materials (ACMs). These materials are not considered dangerous until they start to deteriorate or become disturbed, leading to the release of asbestos fibers into the air. Once the fibers are inhaled or ingested, they can remain in the body for decades, leading to severe health issues.
