Asbestos is a naturally occurring mineral that was widely used in building materials from the 1950s to the 1980s. It was a popular material due to its durability, resistance to heat and chemicals, and affordable cost. However, it was later discovered that asbestos is a carcinogen and can cause serious respiratory illnesses such as asbestosis, mesothelioma, and lung cancer.

Asbestos can be found in a variety of construction materials such as roofing, insulation, and flooring. It can be difficult to identify asbestos without proper testing, as it is often mixed with other materials. The only way to confirm the presence of asbestos is through professional asbestos testing.
