Asbestos is a naturally occurring mineral that was commonly used in construction materials such as insulation, roofing, flooring, and cement. It was primarily used for its heat resistance and durability. However, it was later discovered that asbestos fibers could cause serious health problems when inhaled.

The inhalation of asbestos fibers can lead to various diseases including lung cancer, mesothelioma, and asbestosis. Asbestos exposure is still a significant risk in older buildings, and it is essential to ensure its safe removal to prevent any hazardous health effects.
