Asbestos is a naturally occurring mineral that was used in the construction industry for its heat-resistant and insulating properties. However, it was later discovered that asbestos is a hazardous substance that can cause serious health problems if inhaled.

Exposure to asbestos can cause a range of respiratory diseases, including lung cancer, mesothelioma, and asbestosis. This is why it is important to ensure that any asbestos-containing materials are disposed of safely and according to regulation.
