Asbestos is a hazardous substance that can be found in many older buildings. It was commonly used as insulation and fireproofing material before its health dangers were discovered. Asbestos fibers can easily become airborne when disturbed, and when inhaled, can lead to lung cancer, mesothelioma, and other serious health problems. It's important to handle asbestos waste properly to minimize the risk of exposure to yourself, your family, and your employees.
