Asbestos is a tiny fiber that was used in the past primarily as insulation. It was also added to some building materials to provide added strength and flame resistance. The problem with asbestos is that it has been shown to cause lung cancer and mesothelioma in individuals that were exposed to large amounts of free-floating asbestos fibers in the air. These conditions typically did not become apparent until around 30 years after the exposure. Because of the health hazards of asbestos fibers, its use in insulation and paint was banned in the 1970’s.
What you need to know about asbestos
Homes built prior to the 1970’s could contain asbestos in insulation, plumbing, paint, wall joint compound, and other building materials. However, as long as the materials are in good condition, they pose no danger. Asbestos is only a threat if the fibers are released into the air and can be inhaled.
Renovations or demolitions of materials containing asbestos can release the fibers into the air. Therefore, the National Emissions Standards for Hazardous Air Pollutants (NESHAP) requires the owner of any property containing asbestos building materials to get an asbestos inspection prior to any demolitions or renovations of that property.
How can asbestos be removed?
If your home contains asbestos, you have two options: removal of the material or sealing the material to prevent it from releasing fibers. Either option requires the help of a trained professional.
