Asbestos is a hazardous substance that was commonly used in construction and insulation materials before its dangers were known. Exposure to asbestos can cause a range of serious health problems, including lung cancer, mesothelioma, and asbestosis. While asbestos-containing materials are unlikely to cause harm if they are undisturbed, they can pose a serious risk if they are damaged or removed incorrectly.

In addition to the health risks associated with asbestos, it is also a hazardous substance that must be disposed of properly. Asbestos-containing waste is classified as hazardous waste and must be handled, transported, and disposed of in compliance with strict regulations.
