Asbestos is a hazardous substance that can cause serious health problems when it is inhaled. It was once commonly used in building materials such as insulation, roofing, and siding. If you have a building that was built before the 1980s, it may contain asbestos.

When asbestos fibers are inhaled, they can cause lung cancer, mesothelioma, and other respiratory diseases. Asbestos should never be disturbed or handled by anyone who is not properly trained in its safe removal and disposal.
