Asbestos is a naturally occurring mineral that was widely used in construction materials, including insulation, roofing, and flooring, until the 1980s. It was popular due to its durability, heat-resistance, and fire protection properties. However, over time it became apparent that asbestos also poses significant health risks.

Asbestos fibers are microscopic and can easily become airborne when disturbed, such as during renovation or demolition work. When inhaled, these fibers can cause damage to the lungs and respiratory system, leading to serious health problems such as asbestosis, mesothelioma, and lung cancer.
