Older sheet flooring products: example of floors that do not contain asbestos

This sheet flooring covering backed with burlap fabric is probably more than a century old.

We examined it in an non-public area of the Justin Morrill Homestead, a historic building in Vermont.

The material has not been tested for asbestos fibers, but where we see what is obviously a jute backing it's not likely that the product contained asbestos..

The possible origin of this product is discussed at Asphalt & Vinyl Floor Tile History - history, dates, and description of the production process and ingredients in asphalt floor tiles, asphalt-asbestos floor tiles, & vinyl-asbestos floor tiles 1900 to present.

Photos of Vinyl Asbestos Floor Tile Laboratory Examination

Processing asbestos floor tile to examine its contents

In the lab, following Walter McCrone's procedure for teasing out asbestos particles from solid materials such as this floor tile, we broke a small corner off for further examination by microscope.

Tiles are broken, not cut, in order to expose asbestos fibers for removal, slide preparation, and microscopic examination using transmitted, reflected, and primarily polarized-light central stop diffusion microscopy.

See our ASBESTOS FLOOR TILE IDENTIFICATION PHOTOS by YEAR for our full list and set of photographs.

Question:

Re the brown "Asphalt asbestos floor tile C" above, I have similar tiles and have an original box without the word Asbestos on it. If I send you a picture and the name, would you be able to tell me if it contains asbestos? - M Ziver 8/16/11

Reply:

M. Zilver, depending on the year or age, indeed there were epochs in which both asbestos-containing and non-asbestos-containing lookalike flooring was produced. If we can recognize the product with confidence I'd be glad to say so; or we can give further advice about testing. I'd like to see photos of the tile pattern, tile back if there are any markings, all markings on all sides of the packaging, and in addition I'd like to know the tile size and its thickness. We look forward to hearing from you. Use the CONTACT link to send me photos.

Question: Possible asbestos-containing floor tiles in a school, questions about proper handling

Hi. I have a question about asbestos in floor tile and its removal. I work at a public school and the school had a contractor come in to remove some flooring that was starting to "buckle up" in some areas due to water seeping underneath it. When the contractor came I happened to be around and I asked him before he started if the tile could be asbestos (the school was built in 1952). He looked at it and said it wasn't 9x9 inch, and he was'nt sure what was underneath it yet, so he could'nt say for sure.

When I started at the school I was made aware by my boss that there is asbestos tile underneath the carpet in the classrooms, but he didn't mention the hallways, where this work was going to be done.

I kept a watch on the contractors as they were removing the tile flooring, (I stayed a safe distance from them...like outside the building through a window). I noticed they used no masks and there was no plastic barriers put up inside the building. They were breaking the tile up though because I noticed them shoveling it up and putting it in the big 55 gallon plastic barrels used for garbage.

They stayed for about 2 days doing this. When they were done they left these filled barrels of the tile for us to dump! I didn't want to be involved at all in their dumping! My boss came though and he said he needed my help in dumping the barrels in the outside container for garbage. I REALLY wanted nothing to do with this and I panicked inside. I was afraid though to ask about its safety. When we went outside to dump them I kept my distance as much as possible.

When we dumped the first barrel I held my breath and we dumped it quickly and a HUGE bunch of dust went into the air. I stepped far away and let the dust clear. I then asked if he had any kind of face mask. He did, but only the N95 kind. I put two on and some goggles. We then dumped the rest. My question is, what are the chances that the flooring contained asbestos, and if it did, would'nt the contractor and our head supervisor that ordered the work know about the flooring? - Mike 8/22/11

Mike

No one can say just from text whether or not the floor tile that was taken up contained asbestos, though the lack of dust control and personal protection sounds to me like an amateur was doing the job. Even non-asbestos-containing dust can be hazardous, especially at acute exposure levels.

From the age of the school (1952) some asbestos containing materials would be expected to be present in lots of items, especially floor tiles. And the contractor's assertion that only 9" floor tiles contain asbestos is incorrect.

- ask your doctor for an opinion about your health and exposure to demolition dust that might have contained asbestos and any respiratory health complaints you may have

- if there is remaining dust or remaining examples of the same flooring they can be tested for asbestos

- building management can make be sure all of the demolition dust has been properly cleaned and removed - if it's asbestos-containing, a higher level of cleaning and post-cleanup testing are needed.

- Don't do more demolition without a competent risk assessment

And for your question of whether or not the contractor would or would not know if the floor contained asbestos?

My OPINION (not a lawyer) is that the contractor is legally obligated to be competent to perform the work for which s/he is hired; at a school, and removing flooring, that should include the ability to recognize a "red flag" that would stop the job until an asbestos hazard assessment has been made by a professional.

Faced with very high costs of an asbestos cleanup, and worried about causing a (perhaps inappropriate) panic among parents of school children, building managers I've met have sometimes opted for an "ignorance is bliss" argument. At a large Jewish Community Center in New York where it was patently obvious that there was asbestos-containing pipe insulation and flooring, the building management showed me a "report" asserting that the building was "asbestos free". The report authors simply stayed out of building areas where asbestos found.

Question: floor tiles below asbestos in a 1950's house may contain asbestos

I was pulling up some carpet in my basement today and found that there is tile on the floor beneath it. That didn't seem like a problem to me except in one corner the tile came up with the carpet and there is a green tile beneath that. The house was built in 1950. should I be concerned that the green tile has asbesto in it?
The tile broke into pieces. - Don Mac 9/5/11

Reply:

Don from the age of materials you describe it's a good chance you have one or more layers of asbestos containing floor tiles, though of course I can only speculate with so little information.

However if the floor is covered with additional layers of tile or even carpeting, it's unlikely that it is being disturbed enough to produce a detectable level of asbestos (from that source) in the building air or dust.

A single piece or two of broken tiles are not measurable; what you want to avoid is demolition making a big dusty mess.

Search our site for "How to Reduce the Hazard Floor Tiles That May Contain Asbestos" or "ASBESTOS FLOORING HAZARD REDUCTION" to read about procedures for handling the flooring.

Question: How can I identify various other brands and product numbers of floor tiles that might contain asbestos?

Do you know if the SEARS brand HOMART 64-7169 asphalt floor tile contained asbestos? - Paul Wright 9/22/11

Have you heard of Dura Floor Plastic Asphalt Tiles? Do they contain asbestos? - Jo Lynn Judka 10/24/11

However, this tile is not 1/8 thick but 1/16 and it was peel & stick. Would this contain asbestos? - David 11/27/11

Is there a way I can forward someone a photo of a school floor to determine if it contains asbestos? I am unable to get back into the building It is closed, but the school dept wants to open it again and is saying that there isn't a problem. I looked through the tiles on your site, but oculdn't find an exact match. The school was built in 1950-1960, but we have no evidence that the tiles have been replaced. Can you help? -

we have an armstrong floor tile (black color) with the following numbers on the back L4 1230 021898. We don't know the year it was installed. Does it contain asbestos? Is there a way to cross reference these numbers? - Dan 5/1/12

We have the San Roque pattern sheet vinyl. Did Armstrong use the same patterns at a later date for their sheet vinyl but without asbestos? We have already started to remove it and I am concerned. - Sue 10/24/2012

We have vinyl sheet flooring that was put in about mid 1984. Is this anything to worry about? When exactly was asbestos banned in the manufacture of sheet flooring? - Peter 11/6/2012

Reply:

David, naturally by email alone no one can say with certainty whether or not a floor tile contains asbestos, but if your flooring matches one of the ACM floor tiles we illustrate here, AND if you are confident about the age (as you suggest) most likely it is an asbestos-containing product. And yes, for sure there were some peel-and-stick floor tiles that contained asbestos in the tile baking.

That does not necessarily mean that you need a costly asbestos remediation job - it depends on the condition of the surface, use made of the area, etc. If the floor is sound you may have the option of simply covering it with a new material.

JoLynn, sorry we don't have information about DuraFloor plastic asphalt tiles. Do you know the age of the product? You're welcome to send us photos (see the CONTACT link at top, side, bottom of our pages), and I'll research further. Certainly up to the early 1980's many asphalt floor tile products contained asbestos.

Dan, while we have published product and lot numbers for some floor tile products, there are just too many of them, thousands. Unlike mechanical equipment like water heaters or furnaces, I have not found a standard of correlation between product numbers and date of manufacture, though it probably was included in widely varying ways by individual manufacturers.

You can narrow down the asbestos question by:

- noting the age of the building itself as that sets the earliest plausible date for its floor materials +/- a year or so to allow for flooring sold from stock

- noting the date of any renovations of the building

- noting whether or not there are multiple layers of flooring or other similar changes that give a renovation history

- noting information on any packaging used for the floor tiles - sometimes an extra box of floor tiles is left and stored in a building, intended to supply future repairs or changes to the floor

- comparing the appearance of your flooring to the photographs we provide in these tile identification articles

- sending a small sample of flooring to a certified asbestos testing lab

For a tile floor of unknown constituents, do not do something foolish such as grinding, sanding, power sawing, or a dusty messy demolition.

Peter,
I think you mngh want to ask Armstrong, but in NY case, if you remove materials following the recommended procedures and avoid making a dusty ness you should be OK

Question: dealing with unknown floor tiles

Armstrong-like Excelon (C) Daniel FriedmanI purchased a co-op built in the 1950's. I need to put down a new floor. The last layer of flooring is green 9x9 vinyl tiles. The pattern looks close to seneca white but the background is light green with dark green pattern.

There is black tarry stuff underneath. The tiles are extremely thin. I ripped out the tiles and the plywood underneath them in the corner about 18" square.

The super told me to leave it alone as it might be asbestos, but all the contractors who have seen them, seem not to be worried about ripping up the tiles. I would feel better to play it safe and just floor over them. How do I e-mail a picture to you? - Jeanie in Queens NY 11/13/2011

I have a early 60's home with both bathrooms having what appears to be a solid surface material poured over a greenish felt. The flooring is tan with colored flecks in it throughout. I have looked for the material but haven't found any info. Does anyone know what it is? Is it possible that this material contains asbestos? - Dan 1/10/12

I have an old ranch home w/ sheet lino.x2 layers, over OSB board, over another type of flooring over old hardwood. From what I can see so far. The hardwood has blunt square ends, and is about 3-4" wide and appears to have paint on it. I know there is some rot in that area and would need replacing from reclaimed wood. My question is what is the best way to remove all the lino and OSB and floor below that to get to the hardwood? I know it's going to be labor intensive but not sure how to go about it. - Tracey 2/13/2012

Utility room floor installed 1971 is Armstrong Excelon vinyl asbestos place and press tiles. Some of the tiles are loose. they are whole..just loose. Please recommend what glue to use to re-install them. - Anne 2/13/2012

I work at a Petland Discounts location that's over 20 years old. I've gotten severe breathing problems at this store. The floor polishing company comes in and polishes the floor every month and there is this thick dust in the air and then it gets all over the products. I am concerned that it contains asbestos. There are also many broken tiles in the store. - Despina 5/22/2012

In my kitchen we have a sub floor, then asbestos tiles, then another sub floor and then a layer of linoleum flooring down. We want to lay another floor down but our floor is already up an inch with everything on it. We want to removed the whole flooring but have no clue how we should go about doing this without getting the asbestos in the air. It is also laid in our hallway and our whole basement. Thank you so much for any help you can provide. - Gigi - 6/11/2012

I was going to put new ceramic tiles in the kitchen floor, but when I removed the transition between the wood floor and ceramic tiles I saw vinyl tiles under the kitchen floor. My question is how I would know that the vinyl tiles are asbestos or not? - Mike 7/10/2012

i removed floor tiles by hand that look very similar to some of the ones you have pictured on your web site about 9 years ago. basically i used an old grill spatula to peel them up off of the cement floor. i did use a dust mask but i was unaware at the time that some older floor tiles contain asbestos. do i have anything to worry about? - Joe 8/1/2012

Hello I scraped up a tile floor in my house and I now fear that it was asbestos. The backing is black not white. It did not grind to dust, but it came off in pieces. The floor is covered in the black backing still and I don't know how I should remove this. Should I be concerned about removing this part? Also I suspect these tiles continue into another room under a rug. I would like to remove them eventually if possible. What do you recommend? - Mandy 10/29/2012

My husband and his family were doing some remodeling on a home we just bought (built in the 1930's). When I stopped by the house i saw that they had ripped out the old flooring in the kitchen and bathroom. Underneath the old carpet and flooring were 9x9 squares that were on top of the original hardwoods. I freaked out because i remembered hearing something about 9x9 tiles and asbestos on hgtv.

These squares are black, but they are flexible, almost like a thick paper or a cardboard rather than a hard tile. We arent sure if it is just some sort of backing, or an asphalt asbestos tile. They had already spent the weekend tearing most of it up and it is all over the place right now. any info/suggestions etc would be very greatly appreciated. - Jennifer 10/29/2012

Reply:

Asbestos-containing flooring in good condition does not have to be removed from a building, and worse, inept removal can create a much greater hazard than leaving most asbestos materials in place.

Asbestos was widely used as a filler in both asphalt-based and some vinyl based floor tiles of varying thicknesses, and extending to some thin, flexible self-adhesive backed tiles as well as some sheet flooring.

See ASBESTOS FLOOR TILE IDENTIFICATION PHOTOS by YEAR for an extensive photo guide to asbestos-containing flooring materials.

Comment from reader: anonymous:

Hey Joe there's always a "risk" when removing anything that has to do with Asbestos. I understand that you probably didn't take caution at all with the removal and you probably weren't wearing the proper protection. There's two things that could be red flags. 1. I'd be worried if you were a constant to heavy smoker. 2. I'd also be worried if you've done this type of removal many times before or after without protection. The only way to know for certain if true damage has been done is tell your Doctor or care provider about this incident and ask for their advice.

Question: did asbestos flooring come in just tiles or also in roll or sheet flooring?

Can the asbestos flooring come in tiles only or does it come in a role? - P.H. 12/31/12

Reply:

Asbestos-containing flooring was sold in both individual floor tiles and in rolls of sheet flooring. But just as with vinyl or plastic floor tiles, not all flooring contains asbestos.

LINOLEUM & Other Sheet Flooring includes examples of sheet flooring that often did not contain asbestos. To treat floor coverings in asphalt-based floor tiles or sheet flooring, or vinyl (plastic)-based floor tiles or sheet flooring, it is reasonable to treat flooring sold in the year ranges described in the article above as PACM (Presumed Asbestos Containing Material).

Also the mastic or adhesive used to install flooring may also contain asbestos. Keep in mind also that very often it is not necessary nor even recommended to remove PACM floor coverings. But if conditions require that it be removed, see ASBESTOS REMOVAL GUIDE, FLOORING.

Question: radon system installation drilled through presumed-asbestos-containing floor tiles: how much of an asbestos hazard has that created?

We had a radon abatement system installed in our basement laundry room before we moved in. During our home inspection, the inspector told us there might be asbestos tiles in the basement. We confirmed this is probably the case, even though there is a new floor down there, because under the hot water heater you can see a redish tile (you can't tell the size), followed by a layer of concrete, followed by the new vinyl tile (current day).

To install the radon system they drilled a four inch diameter hole through the floor and then another 4 inch hole through the brick and mortar of the wall to the outside. Now I'm concerned about the asbestos that may have been released into the air from the disturbance.

I've been told there wouldn't be a lot of asbestos released into the air from an event like this one because of the small surface area. Is this true? Also, I've been reading that amphibole types of asbestos were used in mortar as well. If it was just chrysotile from the vinyl tile then it would be less concerning than the "worse types" of amphibole asbestos. However, perhaps they also used amphibole types of asbestos in vinyl tiles? Btw, the house was built in 1948. - B.B. 2/07/2013

Reply:

With the reclama that no one can perform an environmental risk assessment by email, in general, the total dust created by a single hole drilling event should be quite small compared with projects involving demolition of a floor.

It is reasonable to treat the flooring as presumed-asbestos-containing material (PACM); as virtually all of the old suspect floor has been covered, in normal use and occupancy the remaining asbestos-exposure risk to occupants is probably beneath detection.

If you wanted to investigate the asbestos dust risk created by drilling a hole for the radon abatemetn system more scientifically you'd collect what you think is dust left undisturbed from and settled near the area where the work was performed. Send that dust sample to a certified asbestos testing lab and ask them to screen it for you. You can use the procedure at MOLD TEST KITS for DIY MOLD TESTS [Do not send your sample to us.]

Air testing is probably less reliable at this juncture.

Question: is your asbestos floor tile photo library exhaustive, and is the old black floor tile adhesive also a hazard?

I am emailing you after reviewing your very informative website. I have a question about the tile in my basement. We are looking to renovate the space and are concerned about the tile possible containing asbestos. I live in new Jersey and my house was built in 1964. A form of asphalt tile was glued down in either 1964 or 1965. After reviewing your website and the photo section. I do not see our particular tile shown.

My question is: Is your photo gallery all inclusive of tile containing asbestos? The tile can be popped up without breaking any of the tile. Would the adhesive used in laying the tile also contain asbestos? It seems to be a black tar like substance. I would be able to send you a picture of the actual tile if that would be helpful.

 - E.T. 4/10/2013

Reply:

E.T.

Thank you - your question is helpful to me too.

No my photo lib of asbestos containing tile is not exhaustive, though it's the largest one that's been published. There are some companies for whom I cannot find a comprehensive catalog showing all of their tile patterns (Armstrong was the most thorough), and there are companies out of the U.S. whose catalog data is even more scarce. But given how these products were made, it's reasonable to treat old asphalt-asbestos and vinyl-asbestos floor tiles of the appropriate age range as "PACM" or presumed-asbestos containing.

Nobody should panic about this flooring - doing so can result in spending inappropriately. But at the same time some caution is in order such as avoiding making a dusty mess by grinding, steel power buffing, and incompetent demolition. As well, in public spaces such as schools additional regulation may apply.

Where the floor is in good condition there are low cost options that help minimize the risk of asbestos release such as hard coatings.

For floors such as the one you describe, where whole tiles pop up, one can remove such tiles with minimal disturbance of the tile itself, thus minimal asbestos dust release.

But you are right to worry about the tile mastic or "glue" that was used: indeed some mastics, particularly the black asphaltic mastic, often contained asbestos. Asbestos fibers (and possibly asbestos dust filler) were widely used in asphalt-based mastics, glues, and in roof flashing cements. The same caveats apply: if you avoid making a dusty mess you will minimize the risk and hazard of asbestos. We have published wetting guidelines and flooring removal guidelines citing expert sources to help minimize risk as well as cost.

If you are facing a costly demolition job then it may be appropriate to have both the mastic and a section of floor tile tested by a certified asbestos testing lab. The cost is usually around $50./sample or less. If you have other specific questions please let me know. Working together makes us both smarter.

Please keep me posted on how things progress, and send along photos of the flooring you described as well as where it's popped up showing the asbestos if you can. Such added details can help us understand what's happening and often permit some useful further comment. What we both learn may help me help someone else. And by publishing a photo of your unidentified floor tile we invite other readers to comment if they know the pattern, age, and manufacturer.

Question: do self adhesive floor tiles contain asbestos?

(Feb 17, 2014) Anonymous said:
Hi.Can you clarify for me please? Were the asbestos vinyl floor tiles stuck directly to the timber floors without any sort of board or sheet in between? I removed some tiles many years ago and am now trying to remember what they where. I think it was 9x9 tile bonded directly to the timber floor with black mastic. Does that sound correct? I am very worried about my past exposure and would really appreciate your response. Thank you

Reply:

There were self-adhesive floor tiles made into the early 1980's that contained asbestos, though 9x9 self-adhesive were not a size I've seen; usually the self-adhesive or "stick on" floor tiles were 12x12.

And just how much you should worry about past exposure to asbestos from floor tiles is not something we can assess by text chatting; but I point out that unless you ground, sawed, or sanded or otherwise made a dusty mess of floor tiles, the material is not very friable and thus would not put nearly so much asbestos into the air as say the soft asbestos insulation used on pipes.

Question: 9x9 tongue and groove floor tiles and asbestos

(Apr 5, 2014) Anonymous said:
I currently have 9x9 tongue and grove tile flooring in the room that will be the babies room shortly. Some of them are water damaged from a leak in the bathroom in the next room and i would just rather rip them up. These tiles look to be wood (3 layers, just over 3/8 think, with the top layer being glossed)and are placed right on the concrete slab. They are also glued down with a black looking tar substance. Is it possible for this type of flooring to have asbestos in it? Any input is appreciated.

Reply:

Anon I think you sent me photos of this floor an I apologize for not finding time to respond previously.
Most likely you're talking about a laminated wood flooring product that does not contain asbestos. But keep in mind that I can't know that with certainty just by a photo or texting.

Generally if you can pick up piece of flooring without cutting, sawing, sanding, you're not damaging it and so not releasing particles from it regardless of it material. There may be allergenic dust under an old floor for other reasons (bugs, water leaks, mold).

And watch out: if the flooring was glued using a black mastic asphaltic cement, some of those products contained asbestos. You want to avoid making a dust-mess.

(Apr 5, 2014) Anonymous said:
Yes that was me that sent the pics in. Thanks for the reply. I am pretty confident that it is wood laminated tiles. I'm also sure that since they are tongue and groove I wont get away from braking a few but that shouldn't be a big deal if they are asbestos. In case the glue is the black mastic asphaltic cement you are referring too should I just leave that as is once done and let them carpet right over top of it? Thanks

My house was built in 1960 and I have Accotile D.900/D.953 tiles under the carpet in my dining room (once my kitchen). I have subsidence and the contractors say they will not lift the carpet up to see what is going on underneath as the tiles are Asbestos. Can you confirm this, please. Some tiles are cracked. Many thanks Julia Sibun

Reply:

What am I confirming - that the contractors won't lift a carpet to see what's below? That sounds ridiculous. One of them must be an attorney.

Even if the floor tiles are asbestos, if they are not being ground, sanded, drilled, demolished, then the potential asbestos particle release would almost certainly not be detectable.

Asbestos is not radioactive - it doesn't emit "killer rays", and if it did, carpeting wouldn't be a ray-barrier.

Cracked floor tiles and extensively-damaged fragments ARE a potential particle release and should be handled

Question: child removed flooring - was the glue an asbestos-product?

(May 7, 2014) Marcia said:
If a 10 years old child removed tiles from cement floor that took about a week to remove, if the glue was asbestos, was the exposure enough to cause a problem. This person is now 36 what test can be done to tell if they were exposed to asbestos. Thank you

Reply:

Marcia I wish I could answer your question but with absolutely not a shred of actual data on the actual asbestos exposure level it would be wild speculation. It's possible that there was no measurable exposure, or if the flooring was asbestos-containing and was sanded, ground, broken up, such that there was a high dust and debris level there could have been a notable exposure to airborne asbestos.

Consult a physician with expertise in environmental medicine for diagnostic help. The doctor will doubtless examine the patient, take a history, listen to complaints, and may want x-rays or other tests.

Keep us posted.

If the base floor as installed is secure you can usually install thinset tile right over it - strip wax and clean the surface first; don't grind, sand etc. as that'd possibly release asbestos into the air.

Mike if your flooring was installed before the early 1980's it would make sense to treat it as presumed-asbestos-containing-material. I'm reluctant to give a generic answer for an unknown specific product but usually even if you don't match the floor pattern exactly to those we show over at our Congoleum flooring pattern ID section

you can make a reasonable assessment by flooring type and age.

Question: Ceramic tile floor in Italy - contain asbestos?

(July 25, 2014) Thomas C said:
I have a mid-70's ceramic floor tiled terrace (outdoor) in our house near Napoli, Italy; each tiles is 4'" by "7, so pretty small. I'm worried that a) there might be asbestos in the tiles themselves, and b) is the mastic holding them down might have a small percentage too - its not clear if its "thin-set" or mastic. I'm told that mastic was not typically used under outdoor flooring, and when I spoke with a local chemical analysis centre, they said they had never come across asbestos in either scenario, yet I worry when I read these articles of course - would really appreciate your opinion on the likelihood..

Cheers

Question: different asbestos levels in indoor vs ouitdoor tiles & mastics?

(July 28, 2014) Anonymous said:
Thanks Dan - the only one question I have left is whether there was typically different usages for asbestos containing tiles and mastics for outdoor installations - there has only been mention of indoor installations on these articles, so I guess I'm hoping that for outdoor installations it might have been less common/not used?

Reply:

Anon I don't have an authoritative answer but certainly in my experience vinyl asbestos floor tile and asphalt asbestos floor tile are not commonly found in outdoor installations - certainly not in northern climates. But by no means does that mean that some installer may not have tried an outdoor installation.

Some asbestos-containing flooring mastics are and were water soluble, others not.

Question: dealing with asbestos flooring in a Vintage travel trailer

(Aug 4, 2014) Anonymous said:
I am restoring a 1957 Vintage travel trailer. It has what I am assuming is the original tile under carpet. What are the chances it is asbestos? How should I deal with it?

Reply:

Anon,

Chances are very good that the floor tiles from 1957 contain asbestos and it would be prudent to presume so. That's not to justify a panic. If the flooring is intact and you don't do something silly like grinding, sanding, sawing it, the asbestos particle release from the floor is probably below the limits of detection.

Since you're restoring the floor you probably don't want to take the standard advice of installing new flooring overtop the existing floor. Use a liquid cleaner or wax stripper, detergents &c. to clean the floor. Then I would consider a clear hard top coat sealant.

Or install a lookalike floor pattern over top if you prefer.

(Aug 12, 2014) The tile in my house in IL built in 1964 said:
The house located in northern suburb of Chicago, IL was built in 1964. The basement is covered by such tiles. Recently years we had flooding and so some tiles poped out. I am thinking to remove all the tiles and put ceramic tiles. Do you think the tiles contain asbestos? How about the dried glue under the tiles?

I have a picture of my floor tile and wonder how to load it.

It would be prudent to treat 1964-vintage asphalt or vinyl floor tile as presumed to contain asbestos.

Question: how long for a laminate or vinyl floor to start emitting asbestos

(Oct 29, 2014) Charlotte G Bolden said:
How long does it take for laminate and vinyle floors to start emitting asbesto: And how to tell when it starts to become active with asbestos.

Reply:

Charlotte, the asbestos particle release from asbestos-containing floor tiles depends less on time than on conditions. Any activity that abrades the floor surface, such as grinding, sawing, demolition, or possibly using steel-wool buffing machines, and possibly heavy foot traffic, especially if there is granular debris tracked on the floor can cause particle release.

A careful test of settled dust in the area, screening it for asbestos might be a more reliable test to demonstrate that asbestos is being released, though typically inspectors use air testing - a procedure that is unreliable, especially when negative results are obtained. Small changes in building conditions can make a large difference in airborne particle level.

Question: high school student wants to sue for asbestos-suspect floor exposure

(Nov 30, 2014) FuriousMickey said:
Hello! I am in high school currently, a school that was built in the 1950s. Apparently the school has been completely re-tiled in the 70s. There is a missing floor tile in one of my classrooms and in another some broken up floor tiles sort of like a large crack going across the floor. IF the cements under these tiles contained asbestos, do you think I can sue the school district for exposure to asbestos? BTW I'm a competitive swimmer, and it is VITAL I keep my lungs healthy. Thanks.

Reply:

Mickey

"Can" sue, meaning are you physically capable of doing so - sure the answer is yes.

"Should sue" or "would a lawsuit have any merit" is a different question. Most likely the answer is no. You'd have a serious concern if there were broken, damaged, ground, cut, sawn asbestos-containing floor tiles in the school as that would be a high risk of creating airborne dust containing asbestos.

But the level of airborne dust that may be present due to asbestos containing flooring (or mastic adhesive) over which another layer of flooring has been installed is most likely below the limits of detection, even if there is a crack in the floor.

Stay away from your friends who smoke so as to avoid second hand smoke. That's likely to be a greater risk to the health of your lungs.

Question: hazards of broken up asbestos containing flooring under a carpet

1/1/2015 Chilliepepper said:

We started pulling up carpet in our den and found what looks to be asbestos tile underneath. Some of it was crumbling into chunks around the edges, especially as we started to remove the tack board. We covered it all back up with the carpet for the time being, but we need to get rid of the carpet to reduce dust exposure for our allergic son. How should we proceed in dealing with these crumbling edges to minimize asbestos exposure? Also, how serious of an exposure do you think we have already had as a result of being down near the crumbling tile which may have been disturbed when we were pulling up the carpet?

Reply:

Chill

I don't think I can assess an environmental exposure level or risk from an e-text alone, but if you avoided making a dusty mess, if you did not run a vacuum cleaner on broken up or crumbling asbestos-suspect flooring, then we can both be encouraged.

Two articles in the More Reading links above will answer your other questions:

Reader follow-up:

Ok, no dusty mess and no vacuuming, check. A realtor friend has advised having it removed by professionals, since it's started to crumble. "The rest of it may continue to crumble under whatever you put on top of it. And even if it doesn't you are covering a waiting time bomb. Now that you know you have asbestos tile it will likely be something you have to disclose when you sell which could scare away potential buyers. If you remediated it there is likely no disclosure necessary since you fixed it. Either way I would get a pro to evaluate the situation." What do you think?

Reply:

Chill, I can't assess real estate disclosure law for you, but I can advise that if you follow expert recommendations for dealing with asbestos flooring, such as those we cite from the U.S. EPA, you can document that you've done what you should. Generally the asbestos hazard from intact flooring is less if it's left in place and covered-over than if it's removed.

Asbestos is not "radioactive" - it does not emit lethal particles that penetrate through additional levels of flooring. Just be sure that any cleaning done in preparation for flooring-over is done with proper procedures such as HEPA vacuuming, dust containment etc.

Your realtor may be spending your money to reduce his risk, and depending on the condition of your floor, may even be giving incorrect advice that in effect increases both risks and costs.
