Asbestos Linoleum: Is It Hiding Under Your Floors?

The presence of asbestos linoleum in older constructions raises significant concerns regarding indoor air quality. Understanding the composition of linoleum flooring is crucial, as it was a common building material before regulations restricted asbestos use. The Environmental Protection Agency (EPA) provides resources for homeowners and contractors on managing asbestos-containing materials. Identifying friable asbestos in asbestos linoleum requires specialized skills and equipment, often involving professionals certified in asbestos testing.

Asbestos Linoleum: Is It Hiding Under Your Floors?

Linoleum was a popular flooring choice for many years, prized for its durability and affordability. However, older linoleum, particularly that installed before the 1980s, can contain asbestos. This article will help you understand what asbestos linoleum is, how to identify it, and what to do if you suspect it’s in your home.

Understanding Asbestos Linoleum

Asbestos was added to linoleum to increase its strength, flexibility, and fire resistance. The asbestos fibers are typically found in the backing of the linoleum. While not always dangerous, disturbing asbestos-containing materials can release fibers into the air, posing a health risk if inhaled.

What is Linoleum?

Linoleum is made from natural materials, including linseed oil, rosin, cork dust, wood flour, pigments, and calcium carbonate, all pressed onto a burlap or canvas backing. It’s important to distinguish it from vinyl flooring, which is a synthetic material.

Why Was Asbestos Used in Linoleum?

As mentioned earlier, asbestos improved the material’s:

• Durability: Making it more resistant to wear and tear.
• Flexibility: Preventing cracking and making it easier to install.
• Fire Resistance: Providing an extra layer of protection.

Identifying Asbestos Linoleum

Determining whether your linoleum contains asbestos requires careful observation and, ideally, professional testing.

Visual Clues

While visual inspection alone cannot definitively confirm the presence of asbestos, certain clues can suggest that your linoleum might contain it:

• Age of Installation: Linoleum installed before the 1980s is more likely to contain asbestos.
• Tile Size: Asbestos linoleum tiles were often produced in 9×9 inch squares.
• Backing Material: Examine the backing. A dark, paper-like or felt-like backing may be a sign of asbestos content. Look for a crumbly texture.
• Pattern and Color: Older linoleum often features specific patterns and color schemes that were popular during certain periods. Research common designs from pre-1980.

Testing for Asbestos

The only way to definitively determine if your linoleum contains asbestos is to have it professionally tested.

1. Hire a Certified Asbestos Inspector: A trained inspector will collect a sample of the linoleum without disturbing it excessively.
2. Laboratory Analysis: The sample will be sent to a certified laboratory for analysis. They will use specialized equipment, like polarized light microscopy (PLM), to identify asbestos fibers.
3. Receive the Report: The lab will provide a report indicating whether asbestos is present and, if so, its type and concentration.

When To Test?

You should consider testing your linoleum if:

• You are planning to renovate or remove the flooring.
• The flooring is damaged or deteriorating.
• You have reason to believe it was installed before the 1980s.

Dealing with Asbestos Linoleum

If your linoleum tests positive for asbestos, it’s crucial to handle it safely.

Do Not Disturb the Material

The most important thing is to avoid disturbing the linoleum. This means:

• Do not attempt to remove it yourself unless you are properly trained and equipped.
• Do not sand, drill, or otherwise damage the flooring.
• Do not sweep or vacuum it, as this can release fibers.

Encapsulation

If the asbestos linoleum is in good condition, encapsulation might be an option. Encapsulation involves sealing the flooring with a special coating to prevent asbestos fibers from being released. This should be done by a qualified professional.

Asbestos Abatement

If the linoleum needs to be removed, you must hire a licensed asbestos abatement contractor. They have the training, equipment, and experience to safely remove and dispose of the material.

Regulations and Legal Requirements

Asbestos abatement is heavily regulated. Ensure that any contractor you hire follows all local, state, and federal regulations regarding asbestos handling and disposal. This includes proper notification procedures, waste disposal methods, and air monitoring. Neglecting these regulations can result in hefty fines and serious health risks.

So, now you know a bit more about asbestos linoleum! If you suspect it’s hiding under your floors, take the necessary precautions and get it checked out. Better safe than sorry when it comes to this stuff!
