Asbestos-containing Ceiling Tile FAQs

On 2017-03-06 by (mod) - Reader reports pleural mesothelioma after cutting ceiling tiles on table saw

Jim:

Thank you for that information, though it's of course sad and bad news for which you have my sympathy. Cutting ceiling tiles on a table saw indeed is likely to create a lot of airborne dust, still more hazardous if you didn't wear a HEPA -rated mask.

Even though the relationship between anecdotal reports of exposure and the development of mesothelioma decades later is a difficult one (because other factors and exposures are involved), the case you cite is worth noting by other readers as a warning to always use proper methods for material cutting and for dust control and for personal protection.

Back in the 70's many of us worked with dusty and hazardous materials without taking the risk seriously-enough. Signs of pleural mesothelioma may not appear until 2-5 decades after acute exposure to high levels of asbestos-containing dust. And even then symptoms may develop so slowly as to pass recognitiion for a time.

If you have more memories of the nature of your exposure and what protective steps you did not but could have taken, that might help other readers to stay out of trouble in the future.

Thank you for the comments, Jim.

I installed JM 12"X12" ceiling tile in my basement in 1974. I cut the tiles to fit in the area using my Rockwell table saw. I was recently diagnosed with PLUERA Mesothelioma.

Were the 16" by 32" ceiling panels from the 1941 home ever tested? If so, what were the findings, I have similar panels in the basement of my grandparent's home.

On 2017-01-11 14:13:29.377868 by (mod) - asbestos test lab confirms that Armstrong ceiling tiles didn't contain asbestos

Thanks for the follow-up Anoin-Zach, that will help other readers.

Your lab test confirms what Armstrong reports: that their ceiling tiles didn't contain asbestos.

I agree that small particulate dust is irritating and can be a potential health hazard almost regardless of its composition, and that some small dust particle components that are certainly not asbestos, such as silica or even small mold spores or bacteria-contaminated dust are hazardous.

On 2017-01-10 21:55:56.972935 by Anonymous

(mod) - Thanks for the feedback! We eneded up getting a sample of the tile tested by one of the approved labs in the US. Report came back negative for asbestos. It was 80% cellulose, 10% binding matrix, and the remaining percent was a fiberglass and latex paint mixture.

So no asbestos in the Armstrong ceiling tiles at our house, however the cellulose dust (among other dust particles) is still quite hard on your lungs in the short term. Yikes. Warning to everyone else: Wear a mask when demoing ceiling tiles! Thanks!

Zach,

I don't know that specific model number for ceiling tiles.
However at ASBESTOS PRODUCING COMPANIES you will read the following:

Armstrong World Industries, see ARMSTRONG FLOOR TILE IDENTIFICATION

Armstrong ceiling tiles: According to Armstrong Corporation, those attorneys and some home inspectors are mistaken.

Armstrong commented as follows:

Our mineral fibre tiles are made from a combination of the following naturally occurring, processed and recycled materials in varying proportions depending upon the tile type: mineral wool, clay, perlite, cellulose and starch mixed together in a water based process before being cured by heat.

They are then finished with a water based paint, or laminated scrim and paint, decorative facing. All these materials are environmentally safe and our factories comply with ISO 14001.
Asbestos, in any form, is not and never has been used in the manufacture of Armstrong ceiling tiles.
[8]

ON an older home it's prudent to treat ceiling tiles of unknown brand as if presumed to contain asbestos, though certainly not all do.

I wouldn't panic about a single small dust fall, but if there's a lot of dust you'll want to have a proper cleanup done, typically by damp-wiping and HEPA vacuuming. Dust in an old ceiling, even without asbestos, is likely to be irritating, as it contains fabric fibers, insect fragments, perhaps mold and pollen and other allergens.

On 2017-01-06 03:27:49.981602 by Zach

Hi,

Today I was trying to move some ceiling tiles in our basement to fix a ceiling vent. They weren't cooperating so I just pulled them (accidentally breaking them and making some dust). Within a few seconds I was sneezing and coughing from the dust and then I realized I might have made a big mistake.

So I started to get nervous that they might contain Asbestos. Does anyone know if Armstrong 12 x 12 in, off white, Item 225 and 225F, model 0 42369 10650 4, ceiling tiles contain asbestos? I really hope not, but now I am pretty concerned. This house was built in 1967, but I do not know if the tiles were installed then or later. The whole basement has these tiles as the drop ceiling. Thanks! Zach

If the ceiling is from the 60's there's a reasonable chance that it contains asbestos. Search InspectApedia for ASBESTOS TEST LAB to find a list of certified, qualified asbestos test labs - since if there's a dusty mess to clean-up and if there is no asbestos, the job cost will be significantly less.

On 2016-12-25 09:41:37.255012 by Gerry

12" x12" stapled ceiling tiles put up in '60's have fallen down in mother-in-laws house. Only maring on tiles is. Swanboard ansd "made in Sweden". Any thoughts on possible asbestos content likelihood.? I have found no information at all re: Swanboard.. Should I have it tested first?

On 2016-12-23 16:32:39.544131 by (mod) - stains don't cause "asbestos" but loose ceiling debris might be a hazard

Well stains don't cause asbestos but it sounds as if you're talking about cats and the landlord answers "No soap, radio" - which makes no sense whatsoever.

First, if the ceiling is not falling, damaged, fraying, releasing debris, the safest course is to leave it alone.
If the leaks are fixed, a landlord with any sense will paint stains with BIN or another lacquer primer sealer, then repaint the ceiling.

IF the ceiling is falling down or needs to be removed, then IF it contains asbestos there is a potential hazard and the removal needs to be done by a qualified removal company AFTER a test sample confirms that the material contains asbestos.

On 2016-12-23 03:32:01.725916 by Nicole

Hi I live in an apartment building and I believe we may have asbestos in our hallway ceiling tiles. My landlord has been NO help. He claims the stains on the tiles are from a leaky roof that he's recently had fixed.
Is there anyway I can tell ? Thanks!

I am looking at an older home with accoustic ceiling tile, they are 1 foot squares that interlock on 2 sides, they are stapled to the old ceiling on 2 sides. I believe they were installed in the late 60's or early 70s. What are the chances of these containing asbestos?

On 2016-10-06 14:08:34.327407 by pat - foam ceiling tiles are not asbestos

Hi , we purchased a 1977 home with an acoustic cieling on one half of the basement and acoustic cieling tiles (I think) on the other half. I have pictures. The tiles are foam, with a very thin layer of acoustic 'paper' -- it's that thin. I can't find any wording on them but they've been moved around over the last few months to run cables to bedrooms above, etc. Now I am nervous!

Tiles may be 2x4 , but sizes all vary as they were cut to fit. The acoustic ceiling (over drywall) is essentially untouched but a small hole where the owner hung a light from. I am in New Jersey. Any guidance would be greatly appreciated.

John Moore: regarding the ceiling composition, I agree that an asbestos-containing fire-resistant coating is more-likely to have been applied to a ceiling surface, but given the enormous variety of training, skill, experience among people who might be asked to cover ceilings and walls around a boiler, just about anything is possible.

You cannot completely eliminate your asbestos suspicion without a near-complete demolition of the ceiling - something I can't recommend with so little information, but an expert ought to be able to collect test samples from one or a very few strategic locations that could be examined by a certified asbestos test lab (search InspectApedia.com for ASBESTOS TEST LABS to find one).

On 2016-09-02 15:07:07.203224 by (mod)

John,

I had to delete your links as the blazing blinking advertisements were really annoying.

About the ceiling tiles, it looks from your photos as if we're seeing a cellulose product ceiling tile but of course to know for sure if there is asbsestos in the material you'd need to either know the name of the product or to have a test performed by a certified asbestos test lab.

As this is a suspended ceiling it ought to be possible to remove it without creating a hazardous dusty mess in any event.

I live in a house that was built in 1915. There is one room that had wood paneling and a drop ceiling put in at one point with 2'x4' ceiling pieces. I am planning on removing the drop ceiling but wanted an opinion before I remove them. I have links to a picture of a hole that was drilled into it previously and the top of one of the panels

On 2016-08-30 19:23:21.348952 by (mod) - unlikely to find asbestos-containing ceiling tiles covered over by wood-lath and plaster

No, John, it would be un-common (but certainly not impossible) for someone to have installed wood lath and plaster over a previousl layer of asbestos-containing ceiling tiles. The history of use of building materials argues against that sequence.

On 2016-08-30 19:23:21.348952 by JohnMoore plaster ceilings with asbestos tile above?

we have a 3 layer plaster and lath ceiling that was above an old gravity fed octopus. Built in 1920 or 1922. They wouldn't have put any asbestos tiles or any other asbestos product ABOVE the plaster & lathe, would they?

I'm also assuming that there wouldn't have been any loose fill asbestos insulation stuffed between the floor joists above the ceiling either. Is this assumption correct based on the year?

Is it possible to eliminate the suspicion of asbestos in the plaster layers based on the year?

Jon for space and to permit citations I answer your question at JOHNS MANVILLE CEILING & WALL PANELS at http://inspectapedia.com/hazmat/Asbestos_Ceiling_Tiles.php#Mansville in the article above.

If you can send me some sharp photos of the tiles/panels front, back, edge, any markings or stampings, and any packaging I can research more completely and it'd be most helpful. Find my email at the page bottom or top CONTACT link.

I truly apologize for the double post,feel free to delete the bottom one:

Hi there, i recently found a 3 stacked pile(5 ft stacks) on my basement of 2x2 suspended ceiling tiles/panels. they look like the everyday ones that have on a office building ceiling. white on the facing(with 2 different sized pinholes and groves),tan on the back. the ONLY info that has stamped (in red ink) is the following:

Johns-manville corp Pat. D-213367

I have tried and tried to find ANY info about them(online)on the chances that they might contain asbestos.some of the tile look tan in the middle ,some look gray. i want to get rid of them,but BEFORE i move them,i want to make sure that they arent ACM. ANY answer will be greatly appreciated.

Al: depending on the brand and product, chances range from very likely to not at all likely.

What are the chances of tiles in a drop ceiling of a home built in the 1950s having asbestos?

On 2016-06-07 19:41:24.975243 by (mod)

Chances are pretty good - unless the ceiling sections are pure cellulose.

On 2016-06-07 19:22:57.063085 by pattyO

in a school built in the early to mid 50s in the midwest,what are the chances of asbestos being in the ceiling tiles? I am certain that the typical green tiles used on the floor contain asbestos. It is the same color of tiles that you see in every school built back in that era.

THANK YOU IN ADVANCE.

Age, appearance, can suggest that the ceiling tiles might contain asbestos, as you'll read in this article series. Actions range from doing nothing, covering-over, or if you have to do a demolition, testing for asbestos as finding it means more care needs to be taken.

Testing costs about $50. U.S. - use a certified asbestos test lab, search InspectApedia for ASBESTOS TESTING LAB to find an official govt. listing

Hi! We received ceiling tiles for our basement (from and office building built in 1984) the number on the back is USG NFII D070496 0045. C070596 0846.
Because the actual office building was built so late we didn't think it would be an issue but is there any way to track these numbers?

On 2016-03-31 18:34:57.185282 by (mod)

Well that very white interior of the acoustic tile used at what looks like a shooting range makes it suspicious I agree. You'd need a lab test to know for sure if it's asbestos. Search InspectAPedia.com for ASBESTOS TEST LABS for a list if you want to do that - typically labs charge about $40. Keep me posted.

Recently decided to rewire. The basement has old ceiling tiles that I'm concerned about. They are interlocking and stapled to furrowing strips. They are 12" x 12" and about half an inch thick. Smooth surface. House was built in the 40s but I do not believe these are original. They are completely unmarked. Any ideas? Thank you

We are removing some 12"x24" ceiling tile
The first room that we did had tiles that were clearly marked as 2012 however when we started pulling down the tiles in the second room we noticed that they are different.
There are no marks or identifiers anywhere on the tiles except M-CL-1 or M-CL-I not sure which
This building was built in the 1930's but it had renovations done to it in the 1980's, 1990's and 2000's
The building owner claims that they are all less then 10 years old, but he cannot supply us with any proof of this

Any information would be helpful

Thanks

John I can't guess from just the information you provided. If the ceiling tiles are older than the mid 1980's, depending on their composition they might contain asbestos. If it's worth $50. to know, search InspectApedia.com for ASBESTOS TESTING LAB LIST to see some suggestions

Joshua,
One cannot assess an environmental hazard exposure risk from a brief etext, but if you didn't make a dusty mess I suspect that the risk was small.

Leslie, the Sta-Lite cellulose ceiling tile photo that you posted is self-described as a 12" x 24" painted-bevel cellulose product #40-004 - that's wood fibers not asbestos. The image you contributed will be added here to assist other readers. Thank you.

I'd be grateful if you'd take another look at the box for any other labels or markings.

Cellulose is not asbestos but there were asbestos warnings for workers at several Nuwood processing mills.
