Asbestos is a naturally occurring mineral that was widely used in building and construction materials in the past due to its fire retardant and insulating properties. However, it was later discovered that asbestos fibers can cause fatal lung diseases such as mesothelioma, lung cancer, and asbestosis.

Asbestos materials can be found in various parts of a building, including roofing, insulation, wall cladding, pipes, and flooring. Not all materials containing asbestos are dangerous, but it is crucial to have them tested and managed properly to prevent health risks.
