Asbestos is a naturally occurring mineral that was widely used in construction and manufacturing in the UK until the 1990s. Its popularity was due to its heat-resistant properties and durability. However, it was later discovered that asbestos exposure can lead to a number of serious health problems, such as mesothelioma, lung cancer, and asbestosis.

The danger of asbestos lies in the tiny fibers that can be released into the air when asbestos-containing materials are disturbed. These fibers can enter the lungs when they are breathed in, and over time can lead to serious health problems.
