Asbestos is a good material to use in some areas where there is a risk of fire, as it is a completely nonflammabale material. However, if improperly installed or handled the fibers can be inhaled and cause a rare type of cancer called mesothelioma. Asbestos has been banned as an insulation material in most residential and commercial settings in the US because the risks are greater than the benefits, although it is still used for certain industrial applications.
