Asbestos is a naturally occurring mineral that was widely used in construction materials from the 1950s to the 1980s. It was popular because of its unique properties: it is heat-resistant, insulating, and strong. However, it was later discovered that asbestos is a hazardous substance that, when inhaled, can cause severe respiratory illnesses such as mesothelioma, lung cancer, and asbestosis.

According to the Health and Safety Executive (HSE), asbestos remains a significant cause of work-related deaths in the UK, accounting for about 5,000 deaths every year. It is why the law requires that asbestos must be handled and disposed of by licensed and qualified professionals.
