Asbestos is a naturally occurring mineral fiber that was commonly used in building materials, such as insulation, flooring, and roofing, up until the 1980s. However, when asbestos-containing materials are disturbed or damaged, they release toxic fibers that can cause serious health problems, such as lung cancer and mesothelioma, when inhaled.

Due to these dangers, asbestos is classified as a hazardous substance, and proper disposal is crucial to protect both the environment and human health.
