Question: worry about remodeling fiberboard panels in a 1959 Pontiac Chief mobile home

I have an 1959 Pontiac Chief mobile home and the 4' fiberboard panels that run the width of the trailer need to be replaced. Is it possible that they would have asbestos? - Bill 11/14/12

Reply:

Bill,

If you are describing a cement board in a 1959 mobile home, yes there's a good chance that the board contains asbestos. It's not a friable material, so if you can replace the material without creating a dusty mess that's good. That means pulling nails or removing fasteners and removing the pieces whole;

DO NOT run power tools like saws or grinders on asbestos-cement suspect materials.

More advice on minimizing the asbestos hazard for a case like the one you describe is in our article

ASBESTOS REMOVAL, WETTING GUIDELINES

If the fiberboard panels you are describing are a wood fiber product

(see SHEATHING, FIBERBOARD) that's not an asbestos material.

Question: worry about asbestos in old square ceiling tiles - do we peek, remove, or cover-up the ceiling during restoration

My home has ceiling tiles similar to the those described as older square ceiling tiles with a smooth ceiling tile finish. The house was built in 1898, and only the two living rooms contain the tile ceiling.

Do we dare peek underneath the tile and disrupt any possible asbestos while we under go the restoration or cover up the tile that may result in bigger problems down the road?? - Reno 11/23/12

If a tile ceiling from the 70's is still intact, with absolutely no crumbling or falling apart, and has recently had a coat of paint put over it, is there any cause for concern that it may possibly be asbestos!?

Reply:

Home Reno, and Anonymous:

Asbestos containing materials are not radioactive - that is, covered-up or encapsulated the material is not harmful.

In general, if conditions permit encapsulation or covering-over of asbestos containing materials (ACM), that is the approach that puts the property at least risk of asbestos contamination, since you're disturbing the marerial as little as possible, and certainly less than if you had it removed.

The asbestos-cover-over caveat that occurs to me is not so much with ceilings as with piping. If we encapsulate ACM covered heating pipes we might figure that some day over the life of the system someone is going to have to disturb that material to replace or repair a leaky pipe. (Though that's probably still less total asbestos disturbance than would be caused by removal).

The ceiling tiles should be treated as presumed to contain asbestos. That means that should demolition or disturbance become necssary for some external reason appropriate precautions should be taken.

That caveat does *not* mean that the ceiling should be removed. Coated, sealed, undamaged, and in an area where damage is not likely rhe safest course is to leave it alone. In the condition you describe it's doubtful that one could detect airborne asbestos from that source.

Question: we burned some old tiles - does that mean they didn't contain asbestos

Some old tiles got into our burn pile. They burned very easily. Am I wrong to assume asbestos products don't burn easily? - Tony 1/3/2013

Reply:

Well yes, sort-of. Some asbestos containing materials include a mix of other fibers and contents too.

In that case the asbestos itself would not burn but the other products could - leaving ash that contains asbestos. We did a literature search for asbestos content in ceiling tile ash but couldn't come up with a thing, suggesting perhaps no one has looked at this question with care.

If you have any doubt and if you have ash remaining from your burn pile that you can pretty much bet is from ceiling tiles, I'd sure like to see the results of an asbestos test lab examination.

My bathroom has older, (not sure exactly how old)decorative ceiling tiles in it. The outside of the tiles kind of feel like a styrofoam type material. However the inside of the tile is a brown, fiberboard type material. No straight fibers. The little that came loose crumbled quite easily when I picked it up. Does it sound like it could be asbestos?

I also uncovered some loose plaster-type stuff on my upstairs ceiling. It has what looks like hair sticking out of it. It's older, so hardtop say what color it originally was. Did the older plaster contain asbestos? It is attached to my upstairs ceiling, and it's also in between the ceiling boards.

If it helps, the house was built in 1940. I am presuming the tiles are the ones put up when the house was built.

The bathroom tiles were previously tested I just found out and contain no asbestos. However there are tiles upstairs which are crumbling.

They are white on the outside, with a wood-type material underneath. No fine fiber bundles or needle like fibers. I will post a pic of those ASAP, and will also have them tested. This is SO frustrating trying to figure out what contained asbestos and what did not.

Anon,

Asbestos fibers are so small that you would not see them individually without a microscope and most likely a high powered one using polarized light or other special means.

Most often wood fiber materials are just that.

Figuring out what contained asbestos can indeed be tricky since we've documented that the material was very widely used across a stunning range of products (Asbestos has some wonderful properties) and more, it was used in both fibrous form and in powder form as a filler.

Thanks to a combination of research, Rosato's original text, and periodic perusal of other asbestos information sources, our list of asbestos-containing-products found at

inspectapedia.com/hazmat/Asbestos_Products.php

along with some supplementary citations from Rosato that we include
forms perhaps the most-comprehensive list of asbestos-containing materials one might find.

When you are not faced with a decision about undertaking a costly renovation or cleanup project that turns on confirming asbestos material for sure (which needs lab testing),

I'm unclear on the cost-justification of sample testing and generally advise that it would simply be prudent to treat the suspect material, such as flooring or ceiling tiles, ask "presumed asbestos-containing materials"

or "PACM" = which means don't grind, sand, or disturb them if it can be avoided, cover and leave in place if possible, and don't panic (which subjects the panic-stricken to price gouging).

Yes painting over an asbestos-suspect ceiling tile should be OK if the ceiling material is intact, undamaged, soundly secured, undamaged, not dropping pieces into the occupied space.

Question: which part of the ceiling tile should be tested for asbestos?

30 Oct 14 Ceiling Tile layers said:

Daniel: I recently took a sample of my ceiling tile to have it test for asbestos. When I pulled the sample, I didn't realize the tile basically has three layers, the Outer Layer (Visible to us and test to be paint/binder ), the inner layer (The brown fibrous material which tested to be cellulose filler), and the back side which appears to be white (which I didn't get a sample to test).

My question is if a ceiling tile contains asbestos, would it have been found in the 2 layers that I had test or does it only reside on that last layer (the back side of the tile)? Do you think I'm in the clear or should that last layer be tested too?

Thanks
Brad

Reply:

Smart question, Brad. Bottom line: I don't know but my OPINION is that the most important material to test would have been the main body or center of the ceiling tile as that's the component most likely to contain asbestos.

Asbestos was added in both fiber form (strength) and fine powder form (body filler) in products such as floor tiles and some ceiling tiles.

If you are talking about your own ceiling and are not faced with having made a dusty mess of demolition and if it were me, my OPINION is that you can stop here.

If there are extra reasons to be concerned, such as planned demo, visible damage and dust, then I'd collect both a settled dust sample and surface samples for three more tests.

Asbestos - Chrysotile 75 - 100%

Asbestos <1%>

Reply:

Yes Sharon, if the materials are damaged, disturbed, cut, ground,chopped, demolished so as to make a dusty mess.

If covered over and sealed the material has been treated following the advice of the US EPA and other experts and in that view you'd have minimzied the hazard.

Sharon if you are going to remove the ceiling it would be proper and safe to have it handled by a professional.

The risk is that you cut, saw, demolish, damage tiles creating asbestos-containing dust that you track through the home, leading to a still greater cleanup cost as well as possible health hazards. A pro will use dust containment, negative air, proper bagging, etc.

Question: looking to match an antique metal ceiling

I am redoing my interior and really trying to get th same ceiling tiles as the existing one. It s exactly the same as displayed on your webstie (inspectapedia.com/interiors/Metal_Ceiling_039_DJFs.jpg).

Sorry Eliott:

I photographed that ceiling in an original installation in a restaurant in Brooklyn, New York. I know it's close to impossible to match exactly old embossed metal ceilings. You might try sending a photo (or my photo) to some suppliers to see what they have that's close.

Often in older buildings where a portion of a metal ceiling has been lost from leaks or other damage the builder installs a completely different pattern and paints them to be less horribly noticeable; an alternative, still uglier, is to cover the whole ceiling with a similar pattern.

Question: advice for home inspectors about asbestos in ceiling tiles

31 JN 2015 Home Inspector said:

i wish they made a small kit that i can just take a small pc off and put it in and run a quick test.

Because i think ceiling tiles are the hardest to recognize if they have asbestos or not. As a home inspector i see alot of homes with asbestos flooring and insulation surrounding the pipes along with loose fill insulation in attics. But ceiling tiles are the trickiest.

Reply:

HI

Unfortunately the proper identification of asbestos requires polarized light microscopy. It's not a chemical test.

Luckily there are some asbestos containing materials that can be reasonably identified by appearance alone (such as pipe insulation) or by the combination of appeareance and age such as some flooring.

Given the popularity of litigation you might want to be careful about disturbing asbestos-suspect material unless you're following a sampling protocol.

I add that I agree that ceiling tiles are difficult to identify by eye alone as containing asbestos or not, though sometimes there's an age indicator or manufacturer ID stamp that can help us out.

Since usually the best advice anyway is to leave suspect materials alone, undisturbed, in place, or to cover them over or encapsulate them if there is a risk of damage, your advice can be reasonable and safe in cautionary form. IMO you should not be advising people to necessarily remove asbestos or asbestos-suspect materials but should be warning them about disturbing it and of course should be warning if suspect material is friable, damaged, in poor condition, being tracked around a building.

Question: possible hazards from collapse of drop ceiling tiles

(Feb 1, 2015) harry said:
Back in 2004, while living in Philadelphia, the drop ceiling caved in in the apartment I was renting. I was in the shower at the time, heard a loud CRASH, stepped out of the shower to see the drop ceiling all over the floor and the air filled with dust. I definitely stepped out into this stuff in a state of confusion and quickly threw on some clothes and ran to the real estate office to report what happened.

It never occurred to until just now that maybe this stuff contained asbestos?? It was the type of drop ceiling that was suspended below the actual ceiling on a metal grid. The whole metal grid caved in brining the drop ceiling down. Pieces everywhere. I believe that a metal lighting fixture that housed florescent bulbs pulled the metal grid down and the tiles with it.

Once I reported what happened, the real estate agency sent someone to clean the place up (removing all of the grid, broken tiles, cleaning all debris) and they paid for all of my clothing that got dust on it to be cleaned. I stayed in the place for a few more months before moving out.

I have no way of testing the tiles, obviously, as the real estate agency sent someone to clean up the place ten years ago. love. I'm actually kind of a little worried here. Should I call the real estate agency? Not sure what the heck good that would do.

I'm suddenly really concerned. This was ten years ago. What should I do? Should I not worry? Probably wasn't asbestos? Arghh.

Reply:

Harry,

You're asking about an unknown material that fell in more than a decade ago. We can't make an accurate guess at what risks you may have faced. Generally the risk would be a function of

- what hazardous materials were present

- exposure level

- exposure duration

- personal health and susceptability

Question: asbestos in plaster from 1903?

(Feb 10, 2015) Sharon said:
Our church was built in 1903, would the ceiling plaster contain abestos?

Reply:

Sharon,

One cannot assert whether a ceiling contains asbestos or not from a simple e-text query. I don't mean to sound glib. We don't know: what material is on the church ceiling, when it was installed or modified, nor what it contains.

Older forms of plaster are typically composed of lime, mortar, horsehair and other additives. But we can't even guess what your ceiling may contain.

IF there is a reason to be concerned, such as a need for disturbance, demolition, repair or other dusty procedures, and if no one knows what material is installed, it would be prudent, and inexpensive (about $50. U.S.) to have a certified asbestos lab test a representative sample of the ceiling material.

See ASBESTOS TESTING LAB LIST for access to certified asbestos testing labs in the U.S. or if you're in another country just ask me for further help.

I live in an old school building and when I sweep my floor I get a lite grey gritty powder on my floor.Is this stuff possibly asbestos falling from my ceiling tiles?Thank you.

Reply:

I can't say, Christine as we don't know what your ceiling is. It's not costly (about $50. U.S.) to have a certified asbestos test lab examine a dust sample.

But before spending even that you might ask about just what are the components of the building ceiling. It would be quite odd for so much of any ceiling product to be falling onto the floor below that you'd get a regular amount of dust or debris sufficient in quantity that you'd see it whenever you swept the floors.

Thank you for replying back to my question.I have square,drop ceiling tiles.I did see a picture of the kind I have on this sight somewhere

.They are painted over and in good condition and when I ask the maintenance guy about the dust he said it was paint falling from the tiles.I told him it was not because I also get little paint balls that I can identify

. It is the white/ blueish powder stuff that I find on the floor.The school building is @ 100yrs old and some residents have bad ceiling tiles and have the same thing occurring and some believe there is possible mold in there tiles and through out the building especially in the laundry room.

There is always a problem with overflowing toilets and other things causing water damage.Just this past winter a pipe broke in laundry room and flooded the floor.I understand by what I am asking you it is hard to answer,but I would like to ask you could this mold and maybe asbestos ,if a women were pregnant, living under these conditions,could it cause the baby to be born with kidney disease? I ask this because my granddaughter was born with kidney disease.The doctors cannot find the cause of her kidney disease.

She is three years old now and just received a kidney transplant and we were very concerned as still are the affects of her living in these conditions.

For what I've been told in past five years living here that he owners do as little as possible as far as maintenance goes. I have been diagnose with COPD and have breathing problems and chest pains and fluids in my lungs and sinuses all the time.

I understand if you cannot give me an answer and I know about testing and all,but money is tight and cannot afford. THANK YOU FOR CARING,GOD BLESS.

Reply:

Christine,

I have sympathy for the question about health risks to pregnant women and babies, but that is a question that you need to ask your doctor.

And before getting too scared about what's falling off of the ceiling (or coming from somewhere else) there are two approaches that make sense to me:

1. a professional inspection of the building to identify visual evidence of health or safety hazards, for example: visible mold over more than 30 sq.ft. of contiguous material, a history of sewage backups not properly cleaned, visible, obvious asbestos that is in fragile condition or being damaged or spread in the building, lead paint hazards, slip trip and fall hazards, etc.

2. to investigate specific dust samples that represent common building conditions, I'd send a representative sample or two to a professional.

Question: smoke alarm sounded and ceiling tiles fell down

(June 3, 2015) Anonymous said:

My mom has a basement that was finished in the late 1960's with a drop ceiling. On Mother's Day the smoke alarm went off in the basement and we all ran down.

Many ceiling tiles were falling out of the ceiling and the ceiling was sagging down by 1 - 1 1/2 feet. We quickly held up the ceiling while my mom got nails so we could nail the ceiling back up to the rafters so it wouldn't all come crashing down.

There was a lot of dust in the air. Unfortunately, my mom, who is 79 and already has compromised lungs, started coughing the next day and continued to deteriorate.

She ended up having to go in the hospital and was there for a week. In the beginning she was coughing up the dust. Now she is back home and we are talking to contractors who specialize in remodeling and removal about getting the tiles down.

We had a plumber come to look for a leak that might have caused this to happen. A leak was not found. The remodeling/removal fellow told me that he didn't think the tiles had asbestos "not in ceiling tiles".

He has a great reputation so I am surprised he would say this but maybe he wants the work. Because there is no "cause" except perhaps old age, my mom is going to have to pay for it all herself. I still feel dust in the air and she cannot go in the basement in this condition. What do you suggest?

Reply:

Anon

In my opinion even if there were no asbestos, exposure to a high level of dust in an older home could be a serious respiratory irritant; other dust components can be irritating, allergenic or pathogenic such as mold or insect fragments or even just find particles of wood-fiber based ceiling tiles if they do not contain asbestos.

TO know what your mom was exposed to you might collect a tape sample of representative dust and have it characterized by a forensic lab. Ask her doctor if she or he agrees that that would be helpful. You might have a ceiling tile fragment tested as well. Typically a lab test for asbestos costs about $50. or a bit less.

You can either perform the clean-up presuming that there is asbestos-containing dust (hire a professional, set up air control, HEPA vaccuuming etc). or wait for that test result.

I would not permit further demolition or renovation work to proceed without proper handling of the dust and debris lest an amateur spread further dust throughout the home thus requiring still further cleanup.

Sam:

A review of the US EPA and other expert advice on asbestos generally advises that if the materials are not damaged, shedding, or in an area likely to be damaged and disturbed, the lowest risk is achieved by leaving the material alone.

We cannot tell from just looking if your sagging suspended ceiling tile contains asbestos or not - you'd need to have a lab test performed or to know the brand or the age or dates of manufature of the ceiling material.

Do you know what constitutes damaged or shedding? I'm not sure if you were able to view the photo or not.

Thanks again.

Reply:

Damaged - shedding means that particles of the product are separating from it and entering occupied space.

Friable - generally means that a material is soft enough that you could smash it with your fingers; Asbestos pipe insulation is friable; cement asbestos millboard is not. Ceiling tiles are a bit in between.

Your photo did not tell me if the warp[ed suspended ceiling tile was an asbestos-containing product or not.

I am trying to figure out if it's worth getting the ceiling tiles tested for asbestos at this time. If the assumption that they are asbestos would make them likely dangerous based on the photo I would like to get them tested.

If the photo would not be alarming even if they did have asbestos I'll leave well enough alone unless we decide to renovate. Any insight you have would be greatly appreciated.

If a material is friable and shedding it could be an asbestos hazard risk.

Question: asbestos in 6ft x 5 ft ceiling panels resembling false wood planks look like fiberglass?

(Sept 30, 2015) Ivan Jones said:
I recently purchased a early remodeled barn for apartment living.

The upper floor has about 6x 5 ft panels that initially appear like pattern used in mobile home walls (false wood planks).

There is bulging areas from apparent historic leaking roof and a few seams that are seperated.

Upon closer inspection the flexible panels appear to have been 1/4 inch thick, and composed of deep yellow filamentous material that breaks down to small sharp fibers (like fiberglass) with relative ease.

Is this asbestos?
I can send pics and my contact is ivansheridan72@yahoo.com

Thank you!

Reply:

It sounds as if you are describing a fiberglass or wood fiber product.

Yellow filamentous material in flexible panels is likely to be fiberglass. Please see our comments above.

Some wood fiber products, though described as "pure cellulose" may have been cross-contaminated by asbestos; the health hazard of the in-situ existence of such intact ceiling tiles is rather arguable and risks are probably small.

Asbestos that is in good condition and that is not in a location where it is likely to become damaged or disturbed is legal and is safe left in place and usually the risk of that approach is less than the risk of demolition.
