Asbestos is a dangerous mineral fiber that was commonly used in building materials in the past due to its fire-resistant and insulating properties. It was used in a wide range of products, including roofing, flooring, insulation, and even car parts.

However, asbestos can be extremely harmful to human health if it is disturbed, as it releases tiny fibers that can be inhaled into the lungs. Over time, these fibers can cause serious health problems, including lung cancer, mesothelioma, and asbestosis.

Because of the dangers associated with asbestos, the use of the material has been heavily regulated in recent years. It is now illegal to use asbestos in most building products, and any existing asbestos must be carefully managed or removed to avoid exposure.
