Asbestos is a naturally occurring mineral that was commonly used in a wide variety of construction materials, such as insulation, roofing, and flooring. It was prized for its excellent heat resistance and durability, but unfortunately, it's also highly toxic. Asbestos fibers, when inhaled, can cause serious health problems, including lung cancer, mesothelioma, and asbestosis.

Because of the risks associated with asbestos exposure, it's crucial to take proper precautions when dealing with any materials that may contain asbestos. This is especially true if you're planning a renovation or demolition project in an older building, as asbestos was widely used in construction until the 1990s.
