Where Is Asbestos Insulation Most Commonly Found in Homes & Buildings?

Prior to the 1970s, asbestos insulation was commonly used in homes. Asbestos is known for its fire resistance and durability. It was used in all kinds of things, including: ⁽⁶⁾

• Attics: Asbestos insulation was typically used in houses constructed between 1930 and 1950.
• Pipes, boilers, and furnace ducts: The asbestos insulation used came in the form of a blanket or paper tape wrapped around these.
• Boilers and furnaces: Builders used cement sheets, millboard, and paper to insulate furnaces and woodburning stoves.
• Walls and ceilings: Asbestos was also used for soundproofing and in decorative ceiling sprays.
• Industrial and commercial buildings: Currently, about 20% of industrial and public buildings still contain some materials made of asbestos. You can find it in insulation, fireproofing, and decorative wall and ceiling coverings.

Although the United States is coming closer to a complete ban on asbestos, we are not there yet. The greatest dangers lie in worn-out, crumbling asbestos and asbestos that is released during demolition and remodeling projects.

Can You Identify Asbestos Insulation Just by Looking at It?

No. Usually, you can’t tell if your insulation contains asbestos just by looking at it. If you have any doubt, play it safe and assume it contains asbestos. ⁽⁷⁾

When it comes to asbestos, do not try to take a sample yourself. It’s best to hire professionals. They come prepared wearing appropriate safety gear. They also know when to take extra precautions if necessary. ⁽⁸⁾

Special labs exist to test for asbestos. Anyone taking asbestos samples or testing them must meet certain requirements. The U.S. Environmental Protection Agency (EPA) recommends having any samples collected be analyzed by accredited labs. Accredited labs meet standards set by the National Voluntary Laboratory Accreditation Program or another accreditation organization. These labs make sure the results they obtain are reliable and dependable. ⁽⁹⁾

What Should You Do If You Suspect Asbestos Insulation?

If you suspect your insulation contains asbestos, you should follow these general safety guidelines: ⁽¹⁰⁾

1. First and foremost, do not even touch any material you think might contain asbestos. Do not disturb it in any way. That’s how the dangerous asbestos fibers can get released into the air.

2. If the possible asbestos-containing material is not worn out or damaged looking, you can leave it alone altogether. If the material is in good condition, there is less risk of release of the dangerous fibers.

3. Even with slightly damaged material you suspect might contain asbestos, sometimes the best thing you can do is limit your access to that area.

4. Overall, don’t dust, sweep, or vacuum material you think might contain asbestos. Don’t sand, saw, scrape, or drill holes in it. Don’t use abrasive brushes or pads to clean the area.

5. If you need to do remodeling or repair work, hire a professional.

If you have questions about how to handle asbestos materials in your home or office, you can contact a regulatory office in your state directly for more information. Many states oversee an asbestos program. Your state department of environmental protection or health is also a good resource. ⁽¹¹⁾

States provide up-to-date listings of training courses for professionals handling asbestos as well. Some states employ contacts who specialize in federal requirements such as the Asbestos Hazard Emergency Response Act and the National Emission Standards for Hazardous Air Pollutants. ⁽¹²⁾

What Health Risks Are Linked to Asbestos Exposure?

Asbestos exposure can lead to a variety of health risks. Breathing in asbestos fibers is one of the most dangerous ways to be exposed to asbestos. Over the years, workers in certain fields were more likely to be exposed. Hobbyists are also exposed to asbestos through home remodeling projects and repair work.

Asbestos is a known carcinogen and can lead to: ⁽¹³⁾

• Mesothelioma.
• Lung cancer.
• Larynx cancer.
• Asbestosis, fibrosis of the lungs.

Mesothelioma is strongly linked to asbestos exposure of some kind. Most people who develop this cancer have “inhaled… asbestos particles.” ⁽¹⁴⁾

Can Exposure to Asbestos Insulation Lead to Mesothelioma?

Yes. Exposure to asbestos insulation can lead to mesothelioma. Being exposed to asbestos is the “biggest risk factor” for developing mesothelioma down the road. If asbestos insulation is disturbed, you can breathe in asbestos fibers. These tiny fibers can settle in your lungs. These fibers can harm your body’s tissues. Your cells can become damaged. They can change. These mutations can lead to abnormal cells that spread and become mesothelioma. ⁽¹⁵⁾
