How Dangerous Is Asbestos Floor Tile?

Asbestos floor tile, while generally considered less friable than other asbestos-containing materials, does pose a health risk, primarily when disturbed or damaged. Intact, undisturbed asbestos floor tiles are usually not an immediate danger, but improper removal or renovation can release asbestos fibers into the air, leading to serious respiratory illnesses.

Understanding the Risks

The danger associated with asbestos floor tile stems from the potential for fiber release. Asbestos, a naturally occurring mineral, was commonly used in building materials throughout the 20th century due to its heat resistance, strength, and insulating properties. Floor tiles, specifically 9×9 inch tiles and sheet flooring, often contained asbestos as a binder to increase durability and flexibility.

When these tiles are intact and sealed under wax or other floor coverings, the asbestos fibers are generally bound within the material. However, activities like breaking, grinding, sanding, sawing, or improperly removing the tiles can cause these fibers to become airborne. Inhaling these microscopic fibers can lead to severe health problems, including:

Asbestosis: A chronic lung disease characterized by scarring of the lung tissue.
Lung Cancer: A leading cause of cancer deaths, often linked to asbestos exposure.
Mesothelioma: A rare and aggressive cancer that affects the lining of the lungs, abdomen, or heart.

The severity of these illnesses is often directly correlated with the duration and intensity of asbestos exposure. Even short-term, high-level exposure can increase the risk of developing these diseases, although the latency period (the time between exposure and the onset of illness) can be decades long.

Identifying Asbestos Floor Tile

Unfortunately, visually identifying asbestos floor tile with 100% certainty is impossible without testing. However, certain characteristics can raise suspicion and warrant further investigation. Look for:

Tile Size: Common asbestos-containing tiles are often 9×9 inch squares. Larger sizes, like 12×12 inches, are less likely to contain asbestos, but testing is still recommended.
Age of the Building: Buildings constructed before the 1980s are more likely to contain asbestos floor tiles.
Material and Pattern: Older tiles may have a distinctive, slightly textured appearance. Some also contain asphalt, further increasing suspicion.
Manufacturing Code: Some tiles have markings or codes on the back that can provide clues about their composition. However, deciphering these codes often requires expertise.

If you suspect that your floor tiles may contain asbestos, the safest course of action is to have them tested by a certified professional. This involves collecting a small sample of the tile and sending it to a laboratory for analysis. Testing is the only way to definitively confirm the presence or absence of asbestos.

Safe Handling and Removal Practices

If testing confirms the presence of asbestos in your floor tiles, you have several options:

Leave Them Undisturbed: If the tiles are in good condition and not damaged, the safest option is often to leave them in place and cover them with a new flooring material. This prevents the release of asbestos fibers into the air.
Professional Abatement: If removal is necessary, it is crucial to hire a licensed asbestos abatement contractor. These professionals have the training, equipment, and expertise to safely remove and dispose of asbestos-containing materials in accordance with federal, state, and local regulations.
DIY Removal (Proceed with Extreme Caution and only if permitted by local regulations): While technically possible in some jurisdictions, DIY removal is strongly discouraged unless you have thorough training and understand the proper safety procedures. This includes:
- Wearing appropriate personal protective equipment (PPE), including a respirator certified by the National Institute for Occupational Safety and Health (NIOSH), disposable coveralls, gloves, and eye protection.
- Wetting down the tiles to minimize dust.
- Sealing off the work area with plastic sheeting to prevent the spread of fibers.
- Disposing of the asbestos-containing materials in accordance with local regulations.
- Thoroughly cleaning the work area with a HEPA vacuum.

Even with precautions, DIY removal carries significant risks, and improper procedures can lead to serious health consequences for yourself and others.

Asbestos Floor Tile FAQs

Here are some frequently asked questions about asbestos floor tile:

FAQ 1: Are all old floor tiles asbestos-containing?

No. While many floor tiles manufactured before the 1980s contained asbestos, not all did. Testing is the only definitive way to determine if a tile contains asbestos.

FAQ 2: Can I just put new flooring over asbestos tiles?

Yes, in most cases, covering asbestos floor tiles with new flooring is a safe and effective way to manage the risk. This encapsulates the asbestos and prevents fiber release. Ensure the existing floor is structurally sound and that the new flooring can be properly installed without disturbing the asbestos tiles. Check local regulations as some jurisdictions might require abatement despite covering.

FAQ 3: What kind of respirator do I need for asbestos removal?

You need a NIOSH-certified respirator specifically designed for asbestos protection. Half-face respirators with P100 filters are generally sufficient for limited exposure, but full-face respirators offer better protection. Consult with a safety professional for specific recommendations.

FAQ 4: How do I dispose of asbestos floor tiles?

Asbestos-containing materials must be disposed of in accordance with local, state, and federal regulations. Typically, this involves sealing the tiles in heavy-duty plastic bags, labeling them clearly as containing asbestos, and transporting them to a designated asbestos disposal facility. Contact your local environmental agency for specific disposal requirements.

FAQ 5: What if I accidentally broke an asbestos floor tile?

Immediately stop what you are doing and ventilate the area. Avoid sweeping or vacuuming, as this can spread the fibers. Wet the debris with water and carefully collect it using a damp cloth or paper towels. Seal the materials in a plastic bag and dispose of them properly. Consider hiring a professional for cleanup if a significant amount of dust was generated.

FAQ 6: How much does asbestos testing cost?

The cost of asbestos testing can vary depending on the laboratory and the number of samples tested. Expect to pay between $50 and $150 per sample.

FAQ 7: What qualifications should an asbestos abatement contractor have?

An asbestos abatement contractor should be licensed and certified by the state or relevant regulatory agency. They should also have experience in removing asbestos-containing materials and a proven track record of safe and compliant work practices. Request references and check their credentials before hiring.

FAQ 8: Is asbestos floor glue also dangerous?

Yes, the mastic or glue used to adhere asbestos floor tiles often contained asbestos as well. Removing the tiles can release asbestos fibers from the glue. Proper abatement procedures should address the adhesive residue.

FAQ 9: Can I sue if I develop an asbestos-related illness?

If you develop an asbestos-related illness due to exposure to asbestos floor tiles, you may be able to file a lawsuit against the manufacturers of the tiles, the building owner, or other responsible parties. Consult with an attorney specializing in asbestos litigation to discuss your legal options.

FAQ 10: Does homeowners insurance cover asbestos removal?

Homeowners insurance policies typically do not cover asbestos removal unless it is directly related to a covered event, such as a fire or water damage. Check your policy carefully for specific exclusions and limitations.

FAQ 11: Are there any grants or financial assistance programs for asbestos abatement?

Some state and local governments may offer grants or financial assistance programs for asbestos abatement, particularly for low-income homeowners. Contact your local housing authority or environmental agency for information on available programs.

FAQ 12: What is the permissible exposure limit (PEL) for asbestos?

The Occupational Safety and Health Administration (OSHA) has established a permissible exposure limit (PEL) for asbestos in the workplace. The current PEL is 0.1 fibers per cubic centimeter of air (0.1 f/cc) as an eight-hour time-weighted average (TWA). It’s critical to stay below this limit to minimize health risks.

Understanding the dangers associated with asbestos floor tile is crucial for protecting your health and the health of others. By following safe handling and removal practices, and by consulting with qualified professionals, you can minimize the risk of exposure and prevent serious illness.
