Asbestos is a dangerous material that has been used widely in building materials, insulation, and other products. Exposure to asbestos can cause severe health problems, such as lung cancer, mesothelioma, and other respiratory illnesses. Asbestos becomes a serious health hazard when it is disturbed or damaged, releasing tiny asbestos fibers into the air. These fibers can be inhaled and cause damage to your lungs, leading to serious health problems.
