Asbestos exposure most often occurs in the workplace and can cause major health issues, including mesothelioma. Asbestos exposure and home remodeling can also be an issue because many homes built before the Environmental Protection Agency (EPA) placed restrictions on it contained asbestos insulation. Disturbing it during a renovation can release asbestos fibers and cause exposure.
Asbestos fibers, when inhaled, can become lodged in the lungs and airways. Once lodged there, they can accumulate and cause internal tissue damage.
Asbestos exposure is linked to several health conditions, including pleural effusions (a buildup of fluid in the space between the chest wall and the lungs), pleural plaque (a thickening of the tissue around the lungs), and asbestosis.
Asbestos inhalation is also the leading risk factor for mesothelioma, a cancer of the lining of the lungs. This type of cancer is aggressive, spreads quickly, and is often not diagnosed until it is advanced.
Restrictions on Asbestos in the Home
Asbestos was commonly used in construction for years. It was useful for building because it resists heat, fire, electricity, and chemical corrosion.
When scientists discovered the fibers could become airborne and cause illnesses, the EPA placed restrictions on asbestos use; however, the mineral is not completely banned in the United States.
The government initially placed restrictions on certain asbestos-containing building materials in 1973. The EPA banned it completely in 1989.
The federal court system overturned the 1989 ban in 1991. Today, the U.S. is one of few developed nations that have not completely banned asbestos. Asbestos is still used in many home-building materials, but asbestos is required to be contained to prevent it from becoming airborne.
The EPA currently bans asbestos in:
- Corrugated paper
- Flooring felt
- Commercial or specialty paper
- Certain types of spray-applied surfacing materials
- Pipe insulation
- Wall patching compound
- Artificial fireplace embers
Furthermore, any so-called new uses, or products that did not historically have asbestos, cannot contain the mineral.
Due to the overturn of the 1989 EPA ban, several building materials, and other products still contain asbestos:
- Vinyl floor tiles
- Cement flat sheet
- Corrugated sheet
- Roofing felt
- Roof coatings
- Cement pipe
- Cement shingle
- Pipeline wrap
- Non-roofing coatings
How to Spot Asbestos While Remodeling
Modern homes may also contain asbestos because of the overturned ban; however, older homes built before the mid-1980s pose the greatest risks.
A remodeling project on an older home should include a plan for containing or removing any asbestos discovered. If you are worried about asbestos, you can contact a licensed asbestos contractor for help.
Since there are risks associated with asbestos exposure, it is important to understand where this mineral may be in your home. In many cases, asbestos is well enclosed, keeping fibers contained and protecting people from exposure.
However, as you knock into walls, remove plumbing fixtures and pipes, and do other remodeling work, you may be disturbing asbestos fibers and potentially contaminating the air in the house.
Here are some places that are most likely to have asbestos:
- Older vinyl and linoleum tiles and the glue used to adhere them to the floor
- Flat roofing materials
- Insulation around HVAC ducts, furnaces, and pipes
- Outdoor siding
- Caulking and glazing for windows
- Textured paint
- Drywall patching and joint compound
If you demolish or remove something in your home and see a white, fibrous material breaking apart, it may or may not be asbestos. It isn’t possible to tell if you have asbestos unless you are an expert and know what to look for.
If you aren’t sure, the best solution is to call in a trained professional. Asbestos abatement professionals can either contain asbestos or remove it, but you should never try to do the job yourself.
Identifying, containing, or removing asbestos must be done by trained professionals. The risks of exposure are too great to attempt to do this without professional assistance. Licensed asbestos abatement professionals can test for asbestos and deal with it safely.
As you plan to remodel your home, the best way to avoid asbestos exposure is to call a professional before you begin renovations. Find out if you have asbestos in your home and if any may become damaged before you begin. Taking these steps could save a lot of trouble and expense later, not to mention protect you and your family’s health.Get Your FREE Mesothelioma Packet
