Asbestos is a hazardous substance that was commonly used in the construction of buildings up until the 1990s. It was valued for its strength, resistance to fire and heat, and its insulating properties. However, it was later discovered that exposure to asbestos could cause serious health problems, including lung cancer, mesothelioma, and asbestosis.

Due to its dangerous nature, asbestos must be handled with care and disposed of properly. It is classified as a hazardous waste material, meaning it must be disposed of in accordance with strict regulations.
