What is Asbestos?
Asbestos is a natural mineral made up of thin fibers that are resistant to heat, fire, and chemicals. It was widely used for decades in the early to mid-1900s in construction and fireproofing. However, we now understand that asbestos is toxic and carcinogenic.
Where is Asbestos found?
Insulation, floor and ceiling tiles, textured paint, heat-resistant fabrics, pipe wrappings, and other building materials may contain asbestos. Laws and regulations have decreased asbestos use over the years. It is uncommon for asbestos to be in newer homes. However, older homes may still contain asbestos, especially ones built before the 1980s. Asbestos is most hazardous when it is disturbed or falling apart. This releases the fibers into the air where people can breathe them in to their airways.
Health Impacts of Asbestos Exposure
Exposure to asbestos increases the risk of serious health conditions, including lung cancer, mesothelioma, and asbestosis (a chronic lung disease). These diseases often develop years or decades after exposure to asbestos. Why? Because when tiny asbestos fibers are breathed in, they get trapped in the lungs. Over time, this irritates or blocks the airways and disrupts normal lung function. Repeated and long-term exposure to asbestos increases your risk of developing health conditions, but short-term exposure may also be harmful.
How can I protect my family?
The best way to prevent asbestos exposure is to avoid disturbing materials that may contain asbestos. If you suspect a material may contain asbestos, treat it like it does. Certified professionals can test the material for asbestos. Asbestos becomes a hazard when it deteriorates or is disturbed during renovations, remodeling, demolitions, or maintenance.
To reduce the risk of exposure, do not disturb suspected materials, monitor materials for damage or deterioration, and keep people away from suspected materials. Intact and undisturbed asbestos containing materials may not pose an immediate hazard. Asbestos can be sealed (i.e., encapsulated), covered, or removed to reduce risk. Only trained professionals should handle confirmed or suspected asbestos containing materials.

Asbestos testing and mitigation laws vary by state, especially for testing and mitigation in detached single-family homes. Look up the regulations in your local state and municipality to determine what certifications and notifications are required.
