Asbestos is a group of naturally occurring minerals that were widely used in construction materials until it was banned in the UK in 1999. It was prized for its excellent heat resistance, insulation properties, and affordability. However, asbestos exposure is now known to cause several serious health problems, including lung cancer, mesothelioma, and asbestosis.

Asbestos is particularly hazardous when it is disturbed or damaged, such as during renovations or demolition work. Once asbestos fibers are released into the air, they can easily be inhaled, leading to long-term health problems. Asbestos is also a silent killer because its effects may not be apparent for many years.
