Guide to Asbestos in buildings: Asbestos Fibers, Asbestos Dust & Asbestos-Containing Materials that can be Identified by Visual Inspection

While an expert lab test using polarized light microscopy (and in some cases TEM) may be needed to identify the specific type of asbestos fiber, the percentage content of asbestos in a material, or to identify the presence of asbestos in air or dust samples, many asbestos-containing building products not only are obvious and easy to recognize, but since there were not other look-alike products that were not asbestos, a visual identification of this material can be virtually a certainty in many cases.

ASBESTOS IDENTIFICATION IN buildings provides a detailed guide to recognizing asbestos-containing materials in buildings and links to in depth articles about individual asbestos-containing building materials
ASBESTOS LIST of PRODUCTS provides our detailed list of known products in which asbestos was used

Basic asbestos safety advice

The US EPA indicates that not all asbestos-containing products are dangerous. A health risk exists only when asbestos fibers are released from a product [into the air where they are inhaled for example]. Products that are friable (easily crumbled or made into dust that is easily airborne) are more dangerous than products in which binders immobilize the asbestos fibers.

EPA also indicates that not everyone exposed to asbestos will develop an asbestos-related illness or disease. Most people exposed to small amounts of asbestos do not develop asbestos-related health problems. Cigarette smokers are at much higher risk of asbestos-related disease.

Quoting from the US EPA Basic Advice on asbestos in homes:

What if I have asbestos in my home?

The best thing to do is to leave asbestos-containing material that is in good condition alone. If unsure whether or not the material contains asbestos, you may consider hiring a professional asbestos inspector to sample and test the material for you. Before you have your house remodeled, you should find out whether asbestos-containing materials are present.

If asbestos-containing material is becoming damaged (i.e., unraveling, frayed, breaking apart) you should immediately isolate the area (keep pets and children away from the area) and refrain from disturbing the material (either by touching it or walking on it). You should then immediately contact an asbestos professional for consultation.

It is best to receive an assessment from one firm and any needed abatement from another firm to avoid any conflict of interest. In such a scenario as described above, asbestos-containing material does not necessarily need to be removed, but may rather be repaired by an asbestos professional via encapsulation or enclosure. Removal is often unnecessary.

Basic Asbestos Debris Cleanup Advice

In most cases it is safest (and least costly) to leave the asbestos-containing materials alone. For Asbestos handling regulations, see ASBESTOS MATERIAL REGULATIONS and ASBESTOS REGULATION Update.

Friable, damaged asbestos materials in a living area or such materials located where the asbestos is likely to be carried to an occupied space need professional asbestos remediation.

If you are cleaning-up in a building area where asbestos products may have been dislodged, such as a basement where asbestos pipe insulation has fallen to the floor, the US EPA recommends avoiding causing airborne dust and debris - a condition that could be harmful.

If hiring a contractor to remove asbestos, the US EPA guidelines for asbestos removal, for protection of the rest of the building, for proper asbestos waste disposal, and any other local or state environmental regulations must be followed. In most areas contractors must be specially licensed (see Asbestos Removal, Certification) to test or remove asbestos from buildings. In some areas it may be legal for a building owner or another contractor to remove asbestos, though still it must be disposed-of legally.

Do not run a vacuum cleaner or dry-sweep up asbestos debris that has fallen to the floor - you'll simply cause it to become airborne - a potentially harmful condition. Professional asbestos abatement contractors use a combination of wet mopping and HEPA vacuuming to clean up asbestos from building surfaces.
Do not disturb asbestos or asbestos-suspect material if you do not absolutely have to do so
Seal the work area off from the rest of the building if asbestos material has to be disturbed. Simple poly plastic sheeting and duct tape may suffice, but be sure the duct tape is adhered continuously to the plastic edges and that it binds securely - else it may be necessary to secure the plastic using nailed-furring strips. You don't want your containment barrier to fall down in the middle of a cleanup project. Use an air-lock and change footwear or take similar precautions so that you do not bring asbestos debris into other building areas on your shoes or clothing.
Wear an approved respirator, protective clothing, gloves, hat, goggles, that can be disposed-of after the cleanup.
Wet the asbestos with a hand sprayer when moving it;
Drill or cut only if it is absolutely necessary, then do it outside (and having wet the material)
Demolition of asbestos materials during removal should remove the asbestos in the largest feasible pieces, not in many small pieces.
Bag the removed asbestos in sealed plastic bags and (according to the EPA) dispose of it in an approved land-fill (check with your community building department and your state environmental regulatory association)
Perform a final cleanup of the work area using wet mops, sponges, disposable rags/ wipes. Do not track wet asbestos-contaminated water into other building areas.

Are Carbon Nanotube Health Risks Similar to Asbestos?

We are monitoring studies of possible health risks from other products containing carbon nanotubes. The New York Times reported that to date no illnesses have been reported concerning nanotube-containing articles and that current popular consumer products such as tennis rackets that contain nanotubes are of little risk to consumers. But because nanotube-based fibers are very small, they could pose a health risk.

Consumer caution (not fear) are advised. Carbon nanotubes include bundles of fibers that are similar to but more uniform than naturally-occurring asbestos fibers. The Times article "In Study, Researchers Find Nanotubes May Pose Health Risks Similar to Asbestos", New York Times 21 May 2008 p. A-22, reported on an article published at the website of the journal Nature Nanotechnology on 5/21/08.

For details about carbon nanotube health concerns, and health research regarding nanotechnology in industrial or research processes see Nanomaterials Hazards

Certification & Licensing for Asbestos Abatement, Removal, & Cleanup Companies

As we discuss at ASBESTOS REMOVAL, Amateur, Incomplete, building owners arranging for asbestos cleanup, or any other environmental cleanup for that matter, should be sure that the company they are using is properly certified, licensed, and that the work is conducted with proper supervision and by workers who themselves are properly trained.

Failure to take these precautions risks serious consequences including contamination of other building areas by asbestos dust and debris, health risks and harm to the cleanup workers themselves, and future health risks and harm to building occupants as well as potential issues should the property later be offered for sale.

Details are at ASBESTOS REMOVAL, Amateur, Incomplete and Asbestos Removal, Certification. Excerpts are below.

Watch out: in 2010 The New York Times reported [paraphrasing from that article] that over a five year period beginning in 2001 hundreds of asbestos-removal training certificates were given to people who had completed no training whatsoever. The U.S. E.P.A. reported [according to the Times] that Albania Deleon, operating Environmental Compliance Training, a certified asbestos-removal training school in Methuen, MA and the largest such asbestos cleanup training school in the state. 65 to 80 percent of those receiving certification as qualified asbestos removal experts had not received the necessary training.

Many "Graduates from Environmental Compliance Training also obtained jobs through a temporary employment agency also owned by Deleon, were sent out to perform dangerous asbestos cleanup jobs, and were paid "under the table". Deleon was convicted in 2008 of criminal charges but fled the U.S.. She was captured in the Dominican Republic in 2008.

An example of a simple asbestos test report from a certified asbestos testing lab is shown in this asbestos test result.

Frequently Asked Questions about Asbestos Identification in buildings: How to find & identify asbestos-containing materials

Question: Was asbestos used in mobile home metal ceilings?

was any type of abestos insulation used in mobile home metal ceiling? - Morris 11/2/11

Reply:

Morris,

I'm not quite sure I understand the question. Certainly the metal ceiling of a mobile home is not itself asbestos, though if it has been painted with textured or "popcorn" paint those materials may contain asbestos, depending on when they were painted on.

If you are asking about actual ceiling insulation material, it's unlikely that asbestos was used just as building insulation. On some mobile home products asbestos millboard or even asbestos paper might be found as fireproofing.

Question: Is the yellow & brown insulating board found under wall paneling in my 1950's home an asbestos insulating product?

Question: I am currently renovating a home that was built in the early 1950s. The entire second floor was covered with wood paneling. Under the paneling, is 1/2 inch "board" all around the room.

It's yellow on one side (smooth), and brown (paper color/looks like possible cardboard) on the other, and has a type of "fiber" content. I ripped out a hile bunch of it, and now my throat is irritated. Has anyone ever heard of/seen this product? Does anyone know if it contains asbestos? Please let me know. Jim 1/3/12

Reply:

Jim,

the wallboard you describe may have been a wood-product insulating board - see INSULATION IDENTIFICATION GUIDE or for identification photos. Also see Homasote & Other Insulating Board.

Demolishing just about any building material that creates dust, especially old materials that may also have become moldy or may have accumulated a dust of insect or rodent debris, can be a respiratory irritant, a problem for asthmatics, etc. Check with your doctor.

Reader followup:

Thanks Dan, do you know if these products usually contained asbestos? Jim

Reply:

Wood-product insulating means to indicate made of wood materials. I have not found a reference indicating that manufacturers added asbestos to wood product insulating boards, though given the thousands of uses of asbestos, no one can issue a guarantee without testing.

Keep in mind that dust from demolition contains a lot of very irritating materials, including the sorts of items I listed above.

Question: Is the white wooly stuff insulating and labeled Eagle-Picher found in the attic of my 1947 home asbestos?

I was in my attic the other day and there is what looks like wool up there. My house was built in 1947, I'm not sure if it has asbestos in it or not, some of it is white in color and some is black in color and around the furnace I found and peice of paper that says eagle-picher insulation. - Robert 1/5/12

Reply:

Robert, take a look at our photo-guide to identifying building insulation materials, beginning at
INSULATION IDENTIFICATION GUIDE (article links at page left) - and you'll find a link to detailed photos of Mineral Wool - Rock Wool Insulation - a mineral fiber, but not asbestos.

It would be highly unusual for someone to actually insulate an attic with asbestos materials, though once I found a home where that had been done. The owner worked in the heating industry and used corrugated asbestos paper pipe insulation to lay in his attic floor.

Question: Do gas fireplace logs contain asbestos?

We have a great gas fireplace, but lately i have become suspicious that there may be asbestos in the embers below? There is something yellowish and fluffy. It is an open fireplace. We just bought the house (built 1959) and asked both the inspector and a fireplace specialist if it was asbestos and they said no, but how can you tell? I plan on getting in tested, just feeling anxious in the meantime. - Cat 1/6/12

Reply:

Cat:

Your suspicion that older faux-logs in gas fireplaces contained asbestos is well founded. In my OPINION it is just about impossible to tell by visual inspection alone whether or not a gas log includes asbestos in its makeup. The new logs that are asbestos free look just like the old ones and seem to me to be about the same weight too.

You'd need to send a small material sample to a certified asbestos testing lab to know for sure what the gas log contains. But if you know that the logs are quite old, there's a good chance the are asbestos-containing.

The asbestos particle release into the building air from using an old gas log would be expected to be below the limits of detection in normal use. But if the log is mechanically damaged or disturbed, indeed you could create a messy dust that contains asbestos particles.

Watch out: if you're seeing fluffy deposits forming when the gas fireplace is in operation, that's an abnormal condition that might indicate improper combustion and an unsafe, carbon monoxide hazard. Be sure your home has working CO detectors properly placed.

Question: A baby crib was stored near vermiculite insulation. Is the baby crib safe if I clean it?

I have a baby crib stored in my parents attack. It probably has vermiculite insulation loosely laid between the floor boards. Is the crib safe if I clean it? - Pam 5/15/12

Reply:

Pam:

With respect, and not meaning to sound glib, if I cleaned a baby crib it would be safe. By text on a website one can't know what you would do. Elaborating: a baby crib that is made of all hard surface materials can be cleaned of surface dust by washing or perhaps even careful damp wiping. If there is a mattress that was not covered with something to keep it clean you may want to replace it to be perfectly safe.

I do not know that the vermiculite insulation in the location where the crib was stored contains asbestos, but sound advice is to assume so. The $50.+ you'd spend on testing is perhaps better spent on a new mattress and on cleaning.
