Asbestos is a mineral fiber that was commonly used in construction materials until the 1980s. It was popular because of its strength, durability, and fireproofing properties. However, it was later found that asbestos fibers can cause serious respiratory illnesses such as lung cancer, asbestosis, and mesothelioma when inhaled. Asbestos can still be found in older buildings, so it is crucial to have an asbestos survey done if you suspect that your property may contain it.
