Asbestos is a naturally occurring mineral that was widely used in construction materials prior to the 1980s. It was commonly used in roofing, flooring, insulation, and other building materials due to its strength, durability, and resistance to heat and fire.

However, prolonged exposure to asbestos fibers can cause serious health problems, including lung cancer, mesothelioma, and asbestosis. Asbestos fibers can become airborne when disturbed and can easily be inhaled or ingested by people in the vicinity.

That's why it is important to identify asbestos-containing materials in your home or building and take necessary steps to remove them.
