Asbestos is a naturally-occurring mineral that was commonly used in the construction and manufacturing industries until the 1980s. It was valued for its heat-resistant and insulating properties, and could be found in a wide variety of building materials such as insulation, roofing, flooring, and cement. However, it was also discovered that asbestos was a dangerous substance that posed a serious health risk to those who were exposed to it regularly.

When asbestos fibers are disturbed, they become airborne and can be inhaled into the lungs. Once inhaled, the fibers can get lodged in the lining of the lungs, causing damage and scarring over time. This can lead to various respiratory problems such as mesothelioma, lung cancer, and asbestosis.
