Guidelines for Removing Asbestos-Containing Floor Tile (Vinyl-Asbestos Tile / Asphalt-Asbestos Tile)

Is Asbestos-Containing Floor Tile Removal Necessary?

Asbestos is safe and legal to remain in homes or public buildings as long as the asbestos materials are in good condition and the asbestos can not be released into the air.

Spanish asbestos floor tiles (C) Daniel FriedmanWe begin by suggesting that you should not remove asbestos-containing floor tile unless it is really necessary. As with asbestos-containing products in general, the asbestos hazard at a building may be greater from disturbing asbestos-containing materials (ACM) than if they were left alone or covered up.

But in some cases, particularly during certain building renovations or when asbestos-containing flooring is in poor condition and cannot easily be left in place, removal may be necessary.

As we point out at ASBESTOS FLOOR TILE IDENTIFICATION, the US EPA points out in Adequately Wet Guidance, EPA340/1-90-019 that asbestos-containing floor tiles are considered non-friable materials but the materials can become friable with age or by grinding, sanding, demolition, etc.

Here is what the University of Minnesota has to say about the hazards of this type of asbestos-containing floor tiles:

Flooring that contains asbestos, when intact and in good condition, is generally considered nonfriable and is not hazardous.

Heat, water, weathering or aging can weaken flooring to the point where it is considered friable. Friable flooring includes any material containing more than 1 percent asbestos that can be crumbled, pulverized or reduced to powder with hand pressure. This includes previously nonfriable flooring material which has been damaged to the extent that it may be crumbled, pulverized or reduced to powder by hand pressure. Flooring can also be made friable during its removal. Friable materials can release asbestos fibers into the air. Once in the air, asbestos fibers present a health hazard to people who inhale those fibers.

See ASBESTOS FLOORING HAZARD REDUCTION for details. Also see ASBESTOS REMOVAL, Wetting Guidelines.

the US EPA points out in Adequately Wet Guidance, EPA340/1-90-019

Non-friable miscellaneous ACM includes floor tiles, asbestos cement sheet (transite board), siding shingles, asphalt roofing shingles, laboratory benchtops and even chalkboards. These materials may become friable with age, and under harsh conditions. Category I non-friable ACM must be carefully examined to determine if the material is in poor condition, that is, if the binding material is losing its integrity, exhibited by peeling, cracking or crumbling; and is also friable. When Category I non-friable ACM has become friable it is subject to the NESHAP.

If Category I or II ACM is sanded, ground, cut or abraded it is also covered by the NESHAP. Category II non-friable ACM which is damaged to the extent that it has or will become crumbled, pulverized or reduced to powder due to demolition/ renovation activities, is subject to the Asbestos NESHAP.

Miscellaneous materials are wetted in manners similar to those used to wet other categories of RACM. Coverings are saturated with a wetting agent before removal and the asbestos-containing portions fully penetrated with the agent prior to, during and after their removal, while stored in the removal area, and while being placed into disposal containers. Miscellaneous materials that don't absorb water readily (e.g., asbestos-concrete products, and floor tiles) are only required to have wetted surfaces. A misting sprayer may be used to diminish airborne asbestos fiber levels.

Specific Advice on Removing Asbestos-containing Asphalt or Vinyl Floor Tiles

First, here is the US EPA's general Asbestos Advice for Homeowners, quoting from Asbestos in Your Home, U.S. EPA

Asbestos Do's And Don'ts for the Homeowner

  • Do keep activities to a minimum in any areas having damaged material that may contain asbestos.
  • Do take every precaution to avoid damaging asbestos material.
  • Do have removal and major repair done by people trained and qualified in handling asbestos. It is highly recommended that sampling and minor repair also be done by asbestos professionals.
  • Don't dust, sweep, or vacuum debris that may contain asbestos.
  • Don't saw, sand, scrape, or drill holes in asbestos materials.
  • Don't use abrasive pads or brushes on power strippers to strip wax from asbestos flooring. Never use a power stripper on a dry floor.
  • Don't sand or try to level asbestos flooring or its backing. When asbestos flooring needs replacing, install new floor covering over it, if possible.
  • Don't track material that could contain asbestos through the house. If you cannot avoid walking through the area, have it cleaned with a wet mop. If the material is from a damaged area, or if a large area must be cleaned, call an asbestos professional.

Major repairs must be done only by a professional trained in methods for safely handling asbestos.

Minor repairs should also be done by professionals since there is always a risk of exposure to fibers when asbestos is disturbed.

Doing minor repairs yourself is not recommended since improper handling of asbestos materials can create a hazard where none existed.

Removal is usually the most expensive method and, unless required by state or local regulations, should be the last option considered in most situations. This is because removal poses the greatest risk of fiber release. However, removal may be required when remodeling or making major changes to your home that will disturb asbestos material. Also, removal may be called for if asbestos material is damaged extensively and cannot be otherwise repaired. Removal is complex and must be done only by a contractor with special training. Improper removal may actually increase the health risks to you and your family.

Asbestos Floor Tile Removal Procedure, Guidelines, Standards, Regulations

  • EPA Guidance for Controlling Asbestos-Containing Materials in buildings, NIAST, National Institute on Abatement Sciences & Technology, [republishing EPA public documents] 1985 ed., Exposure Evaluation Division, Office of Toxic Substances, Office of Pesticides and Toxic Substances, U.S. Environmental Protection Agency, Washington,D.C. 20460
  • The University of Minnesota source includes advice on removing asbestos-containing floor tiles if removal is required for any reason, and the UM provides examples of do-it-yourself removal procedures that are safe for homeowners as well as examples that were probably unsafe or improper. See Asbestos Floor Tile Removal Guide & Instructions - copy on file as Asbestos_Floor_Tile_Removal_MDH.pdf ] -
  • In general, avoid violent demolition, such as using floor sanders, grinders, or floor stripping machines to remove these materials.
  • Before demolition or removal of asbestos-containing material check your own state or province for regulations that may apply to demolition or disposal of asbestos materials. see Asbestos Regulations: State asbestos regulatory agencies
  • During demolition or removal, this material should be disturbed as little as possible. Asbestos monitoring may be required before, during, and after demolition and removal of asbestos containing flooring. US EPA asbestos monitoring advice is given below.
  • Consider simply installing a new material atop the old asbestos-containing flooring. Remember that asbestos is not "radioactive" - it does not cause injury or illness simply by being present, encapsulated in a substance or covered-over by a new material.
  • In most residential cases testing these floor products is probably not justified, but if you prefer to send asbestos-suspect material samples to an NVLAP certified lab, they usually want three separate samples each about 3/4" in diameter, and charge about $20./sample. Here is the NIST link about those labs: http://ts.nist.gov/Standards/scopes/temtm.htm that has a list of participants. NVLAP is a national voluntary lab accreditation program within NIST (National Institute of Standards and Technology)
  • Guidelines for wetting asbestos containing materials: See Adequately Wet Guidance, EPA340/1-90-019 that asbestos-containing floor tiles are considered non-friable materials but the materials can become friable with age or by grinding, sanding, demolition, etc.

Monitoring for Asbestos Fiber/Particle Contamination During Flooring Removal

How to Develop and Maintain a Building Asbestos Operations and Maintenance (O&M) Program, This information is designed to assist building owners and managers in understanding how to develop and maintain an operations and maintenance program for asbestos-containing materials in their buildings.

  • Monitoring Asbestos-Containing Material (ACM), U.S. EPA, web search 08/11/2010, original source: http://www.epa.gov/asbestos/pubs/section6.html, quoting:

    Periodic Visual Reinspections and Air Monitoring

    A visual reinspection of all ACM should be conducted at regular intervals as part of the O&M program to help ensure that any ACM damage or deterioration will be detected and corrective action taken.

    • EPA's asbestos regulations for schools (the Asbestos Hazard Emergency Response Act, "AHERA") (PDF) (96 pp, 589k), web search 08/17/2010, original source: http://www.epa.gov/asbestos/pubs/2003pt763.pdf, require that an accredited inspector reinspect school buildings at least once every three years to reassess the condition of ACM.

    • The AHERA regulations for schools also require a routine surveillance check of ACM every six months to monitor the ACM's condition. This surveillance can be conducted by a trained school custodian or maintenance worker.

    • While only school buildings are required to have surveillance checks every six months, it is a good practice for other buildings with ACM. The asbestos program manager (APM) should establish appropriate surveillance and reinspection intervals, based on consultation with the building owner and any other qualified professionals involved in the O&M program.

    • EPA recommends a visual and physical evaluation of ACM during the reinspections to note the ACM's current condition and physical characteristics. Through this reinspection, it is possible to determine both the relative degree of damage and assess the likelihood of future fiber release.

    • Maintenance of a set of visual records (photos or video) of the ACM over time can be of great value during reinspections.

    EPA recommends a visual and physical evaluation of ACM during the reinspections to note the ACM's current condition and physical characteristics.

    Additional Asbestos-Contamination Prevention Measures

    • Supplemental Air Monitoring

      As part of an O&M program, a carefully designed air monitoring program to detect airborne asbestos fibers in the building may provide useful supplemental information when conducted along with a comprehensive visual and physical ACM inspection and reinspection program. For employees who are, or may reasonably be expected to be exposed to airborne concentrations of asbestos fibers above the permissible limits set by the Occupational Safety and Health Administration (OSHA), regulations require that the employer conduct both initial and periodic air sampling. For more information about the OSHA exposure monitoring requirements, see the regulations at 29 CFR § 1910.1001(d).

    If the ACM is currently in good condition, increases in airborne asbestos fiber levels at some later time may provide an early warning of deterioration or disturbance of the material. In that way, supplemental air monitoring can be a useful management tool. If an owner chooses to use air monitoring in an "early warning" context, a knowledgeable and experienced individual should be consulted to design a proper sampling strategy. (See Useful Links for more information on air monitoring.)

    This air monitoring should supplement, not replace, physical and visual inspection. Visual inspection can recognize situations and anticipate future exposure (e.g., worsening water damage), whereas air monitoring can only detect a problem after it has occurred, and fibers have been released.

    • Sampling Methods

    Note that the collection of air samples for supplementary evaluation should not use aggressive air sampling methods. Aggressive sampling methods, in which air is deliberately disturbed or agitated by use of a leaf blower or fans, should only be used at the completion of an asbestos removal project inside the abatement containment area.

    • Methods of Air Sampling Analysis

    The most accurate and preferred method of analysis of air samples collected under an O&M program requires the use of transmission electron microscopy (TEM).

    Phase contrast microscopy (PCM), which is commonly used for personal air sample analysis and as a screening tool for area air monitoring, cannot distinguish between asbestos fibers and other kinds of fibers which may be present in the air. PCM analysis also cannot detect thin asbestos fibers, and does not count short fibers.

    TEM analysis is more expensive than PCM analysis. However, the more accurate information on actual levels of airborne asbestos fibers that can be derived from TEM should be more beneficial to the building owner who elects to use supplemental air monitoring in the asbestos management program. TEM analysis is most reliably performed by laboratories accredited by the National Institute of Standards and Technology and who follow EPA’s quality assurance guidelines. (See References, U.S. EPA, Dec. 1989, Transmission Electron Microscopy Asbestos Laboratories: Quality Assurance Guidelines. Washington, DC: EPA 560/5-90-002).

    • Selecting a Lab

      Selection of a reliable and experienced air monitoring firm and analytical laboratory is important, if the building owner elects to conduct supplemental air monitoring under the O&M program. A consultant knowledgeable in air sampling and analysis protocols can be contacted for recommendations if the building owner or APM has limited knowledge in this area. Contact your state asbestos regulatory agency (5 pp, 17k, about PDF) for information on how to find an accredited asbestos professional.

      In addition, the National Institute for Standards and Technology (NIST) maintains a listing of accredited asbestos laboratories under the National Voluntary Laboratory Accreditation Program (NVLAP). You may call NIST at (301) 975-4016.

How to Dispose of Vinyl-Asbestos or Asphalt Asbestos-Containing Floor Tiles

The following advice for disposal of vinyl-asbestos or asphalt asbestos floor tiles is adapted from the Minnesota State Department of Health:

State health departments typically recommend that all asbestos debris and waste is disposed of in a landfill that accepts asbestos-containing waste. There are three methods of disposing of asbestos waste and they are:

  • Contact local waste hauler for special pick-up.
  • Contact licensed abatement contractor for pick-up and disposal.
  • Dispose of waste yourself.

Watch out: if you are disposing of asbestos-containing waste yourself, you should contact your local state health department for detailed instructions. For example, while a landfill may accept asbestos-containing-material (ACM) (as the material may be buried and thence non-hazardous, special requirements may apply to protect workers and buildings from asbestos dust during collection, bagging, removal, and transportation.

- Ref: MN DPH

See FLOOR TILE HISTORY & INGREDIENTS for a discussion of the ingredients and production of asbestos-containing flooring. And see ASBESTOS FLOOR TILE IDENTIFICATION for advice on visual identification of vinyl-asbestos floor tiles or flooring products that probably do or don't contain asbestos. For a strategy for collecting building dust samples, when, where, how many samples to collect, see DUST SAMPLING PROCEDURE.

Frequently-asked questions (FAQs) on procedures for removing asbestos-containing floor tiles or other floor coverings, or on the use of floor rejuvenators and restorative sealants on vinyl-asbestos floor tiles

Floor rejuvenator cleaner (C) D Friedman

Question: how can I seal vinyl asbestos floor tiles so that I can leave the flooring in place?

I am looking for information on Armstrong diecut inserts from around 1952. Also are there any recommended ways to seal these floors so you can enjoy the look but without any asbestos concerns? Thanks, Sarah

[This Q&A originally appeared at ASBESTOS FLOOR TILE PHOTO ID GUIDE, June 2011.

Reply: residential vinyl-asbestos floor tiles in good condition can be gently cleaned and clear-coated or sealed

As we noted at the top of this page, Asbestos is safe and legal to remain in homes or public buildings as long as the asbestos materials are in good condition and the asbestos can not be released into the air.

About sealing vinyl-asbestos tile floors, especially in residential use where school or public regulations and public access worries don't apply, I've had great success using clear-coating floor restorer products.

We just did this recently in a New York home.

Floor rejuvenator cleaner (C) D Friedman
  • The floor was washed with mild detergent and water.
  • Then we used a spray cleaner recommended by the floor restorer manufacturer. The spray cleaner removes old wax residues. See our photo of Rejuvenate™ floor cleaner (above left).
  • Next we used a magic marker to color in some gouges that had marred the floor surface.
  • Finally we coated the flooring with the floor restorer product. The floor looked new, and great. See our photo of Rejuvenate™ floor clearcoat sealant (at left).

    In sum, provided that your floor tile is not damaged and remains soundly glued in place, in residential use it may be fine to seal its surface and leave it alone.

if you maintain a hard clear coating on top of the floor surface you won't be releasing any measurable level of asbestos fibers by normal foot traffic.

Watch out: We advise against using any power equipment such as sanders, grinders, saws, or even steel-wool buffers on vinyl-asbestos flooring out of concern for the effect of grinding of the surface and concomitant release of asbestos particles into the building air.

See ASBESTOS FLOORING HAZARD REDUCTION for details.

Question: Does this tile floor contain asbestos? Home Depot said they won't install new flooring over asbestos-containing floor tiles? What can I do about that?

Asbestos containing floor tiles (C) D FriedmanI am trying to move into a nursing home but have to fix up my house and sell it before I can do that. I asked home depot for a price to install new linoleum in my utility room but they said they couldn't if the existing tile had asbestos.

I looked on your website to see if my tile was pictured there but didn't find an exact match. Would you look at the attached picture and let me know if you recognize this tile as having asbestos? If you don't know, I would be interested in hearing about the pro bono service your website offers for the elderly to determine if the tile has asbestos.

The tile pictured is intact but tile under the washer and dryer has come lose. Thank you - D.H.

Reply: How to confirm asbestos-containing floor tiles? How to install new flooring over asbestos-containing floor tiles

Indeed your floor tiles appear to include a cork-like pattern that, depending on flooring age, may contain asbestos. (See our asbestos floor tile photos beginning at ASBESTOS FLOOR TILE PHOTO ID GUIDE).

A lab test can conclusively identify the presence of asbestos in a floor tile sample, and typically such a test is not costly - perhaps $50. from any certified asbestos testing lab. (Sorry but our entire lab is on forensic assignment out of the U.S. until year end).

Although you report that your local Home Depot representative told you that they "could not" install a new floor over asbestos-containing flooring, it is, at least in any legal or technical sense, not correct to assert that new flooring absolutely cannot be installed over asbestos containing floor tiles. The condition of the existing flooring and the subfloor and structure below determine the prep work needed in any new floor installation procedure.

Home Depot's lawyers may have decided on their floor installation policy, or your local installer may simply prefer to lose business rather than take the risk of being blamed for creating a dusty dangerous asbestos mess if they work improperly with the material (such as grinding, sawing, or creating dusty demolition - usually demolition or removal is not necessary). And we would agree that if the floor were in bad condition so that demolition and removal of the floor is really required, then the job should be handled by a trained and competent asbestos abatement/removal company.

Example of the OPM problem: the consultant or contractor spends other people's money, sometimes unnecessarily, in order to reduce their own risk

But your photo shows an intact floor surface. So we suspet that there may also be what we call the OPM (other people's money) problem here: it is often much safer and absolutely free for a consultant or contractor to recommend to a client that s/he perform a costly procedure that may or may not be really necessary. The procedure reduces risk for the contractor at no cost to them since the client is paying for the procedure, test, or removal.

Alternatives for Installing New Flooring over Vinyl-Asbestos Floor Tiles or other Asbestos-Containing Floor Coverings

When installing new sheet vinyl or other flooring, typically the existing floor surface has to be sound and smooth. Options for proceeding range from

  1. the worst case of a requirement of removal of a badly-damaged floor surface or removal and re-framing and reinstalling new subflooring over rotted damaged floors and floor structures
  2. to common cases: a few lost tiles over a structurally sound subfloor and floor: the installer may install a veneer of solid core plywood or even hardboard to provide a smooth level surface, nailing the veneer through the existing floor and to the subfloor and joists below
  3. to simple cases: one or two lost or loose tiles (such as those under your washing machine) are removed and the space or opening filled level with the surrounding floor using a suitable floor leveling compound or patching material.
