Asbestos is a fibrous material that was widely used for insulation, fireproofing, and other applications in the past due to its durability, heat resistance, and affordability. But asbestos is also a hazardous substance that can cause serious health problems when inhaled over a long period of time. Asbestos exposure has been linked to lung cancer, mesothelioma, and other respiratory diseases. That is why proper asbestos disposal is crucial to protecting your health and the environment.
