Q: Do all gravity furnaces have asbestos?

• <div><p>No, but it&rsquo;s common that they do. Gravity furnaces weren&rsquo;t terribly efficient so wrapping either the ductwork in asbestos, the furnace itself, or both, was something done regularly. This allowed the system to retain more heat. At the time, this greatly enhanced the efficiency of the furnaces but it wasn&rsquo;t until later that we became aware of just how carcinogenic and dangerous asbestos could be.</p></div>

Question 1

Do home inspections check for asbestos?

Accepted Answer

•

Unfortunately, home inspections do not check for asbestos because of the liability factor involved. That’s why you should hire a trained professional with specialized equipment to test for it.

They will inspect all areas of the home and take samples of various materials to test. Opting for an asbestos inspection can prevent the risk of exposure to this hazardous material and save on costly repairs that may be required.

Question 2

When was asbestos banned from pipe insulation?

Accepted Answer

•

The Environmental Protection Agency (EPA) banned the use of asbestos pipe insulation in certain applications in 1975. It released further bans in 1989 and 2019. While asbestos pipe insulation was common from the 1930s to 1970s, its use fell off after the 1970s due to public concern and the EPA's actions.

Question 4

Should I have my home tested for asbestos?

Accepted Answer

•

Many homeowners may never have to test their homes for asbestos. Asbestos particles are only dangerous if they become airborne. If you plan to do construction or notice damage to piping, siding, or drywall, you should hire a specialist to test for asbestos.

If you plan to remodel your home or have any concerns, you should have your home tested for asbestos just to be safe.

Question 5

What years was asbestos used in floor tiles?

Accepted Answer

•

Asbestos was most commonly produced and integrated into building products from the 1920s to the late 1980s. In reality, asbestos use should have ceased much sooner because asbestos was linked to cancer in studies produced as early as the 1950s. You can even extend that number past the 1980s due to stockpiled materials and because some countries treat asbestos use differently. It may also be found more in commercial applications than residential.
