Asbestos is a naturally occurring mineral that was widely used in construction until the 1970s due to its heat resistance, insulation properties, and durability. However, it was later discovered that asbestos is highly toxic and exposure to it can cause a range of serious health problems, including lung cancer, mesothelioma, and asbestosis.

Asbestos-containing materials can be found in a variety of places, including insulation, ceiling tiles, floor tiles, cement, and roofing materials. These materials can release asbestos fibers into the air when they are disturbed, such as during renovations, demolition, or routine maintenance.
