Asbestos is a naturally occurring mineral that was widely used in the construction industry until the 1980s. Asbestos is heat-resistant and has excellent insulating properties, making it ideal for use in building materials such as roofing, insulation, flooring, and cement. However, asbestos is also a hazardous substance that can cause serious health problems if inhaled. Asbestos fibers are tiny and can remain suspended in the air for hours, allowing them to be easily inhaled. Once inhaled, these fibers can penetrate deep into the lungs and cause lung cancer, asbestosis, and mesothelioma.
