Asbestos products & applications:
Common forms in which asbestos was used in building materials & products.
This article provides a master list of the forms in which asbestos was used, a list of known asbestos-containing materials, and links to detailed articles about individual asbestos-containing products & materials found in buildings and in a wide range of products used in both home and industry.
This document assists building buyers, owners or inspectors who need to identify asbestos materials (or probable-asbestos) in buildings by simple visual inspection. We provide photographs of asbestos containing materials and descriptive text of asbestos insulation and other asbestos-containing products to permit identification of definite, probable, or possible asbestos materials in buildings.
Note that asbestos may be present in still other substances and even products, not by its deliberate use or design, but because it occurs naturally, such as asbestos that is found in some talc powders (amphibole asbestos).
Note that while this is the most extensive list of asbestos-containing products & materials it is of course incomplete, as asbestos was used in thousands of products and materials and is still used in many. CONTACT US to add items and photographs to this list of asbestos containing materials.
Asbestos in many forms was discontinued in all home construction uses beginning in 1990, but beware: pre-1990 products might have been used
in some homes built shortly afterwards.
Low asbestos risk in some materials: One should note that some of these products contain such small amounts of asbestos, or asbestos in forms not easily converted to airborne
fibers (non-friable), that the risk from the product is likely to be very small. One might elect to dispose of an old asbestos-containing
toaster, but not to hire an environmental test firm or asbestos abatement company for that procedure.
Many other asbestos-containing products, both historic and among some current products, encapsulate the asbestos fibers in cementious or resinous materials which minimize the possible release of asbestos fibers into the air.
Note: most of the uses of asbestos listed here are obsolete and the products mentioned have not been manufactured for quite some time. However these
products may still be encountered, particularly in older buildings and among old consumer products.
However some current materials may contain and are permitted to contain asbestos. In May 1999 Asbestos Materials Bans Clarification was issued by the U.S. EPA clarified that there are some
categories of asbestos-containing products that are NOT subject to a ban.
For example, the Asbestos National Emission Standards for Hazardous
Air Pollutants, or NESHAP) rules issued in November, 1990 prohibits spray-on application of materials
containing more than 1% asbestos to buildings, structures, pipes, and conduits unless the
material is encapsulated with a bituminous or resinous binder during spraying and the
materials are not friable after drying. [Italics inserted by -DF].
These classes of asbestos fibers vary widely in size and also, depending upon the matrix of bonding or adhesive material and the mix of asbestos with other materials, the friability and release of asbestos particles from various materials varies very widely from probably below detection, to very great.
It is also useful to understand that the form in which asbestos was used ranged among a number of forms.
The list below (adapted and expanded from the nearly-complete asbestos product list found in Rosato) lists forms of asbestos-containing products.
Asbestos in Adhesives - are described in detail
at ASBESTOS OTHER PRODUCTS Asbestos was used in mastic adhesives for flooring, ceilings, and in roofing cement or flashing cement as well as other adhesive products.

Question: was asbestos used in clothes dryers & clothes dryer belts?
2016/04/15 Vanessa said:
Hi. I have a front loading clothes dryer (probably from late 80s) that is getting old and has some form of material coming through around the inside of the door. It's white-gray, flexible, and not rigid. I tried pulling on a couple of the fibers sticking out to break them off but they wouldn't break. I'm assuming it is something they used as insulation. What could this material be?
2016/04/15 Nick said:
I also have some strands of material coming from the inside ring of the dryer opening on my dryer built in 1984 in Canada. It meets the same description as Vanessa mentioned. Should I be concerned of possible asbestos? Is it likely some other also unwanted material? Thanks
2016/08/25 Chris said:
Do old clothes dryers contain asbestos? I read online from a few sources that old clothes dryer belts, especially belts not made in USA, often contain asbestos and that its one of the largest causes of asbestos exposure in a household. Is this true? I can't find much on it. My dryer was manufactured in Canada in 1984, should I be concerned? Thanks
Reply: yes. Here is where asbestos was used in clothes dryers including felts, combustion chamber insulation, drive belts, electrical components
Vanessa and Nick, it'd be unlikely that a late 1980's clothes dryer sold in the U.S. or Canada would still have contained asbestos.
Chris: Clothes dryer belts in modern machines are typically fabric-reinforced rubber, but of course it's possible that asbestos was indeed used in some older clothes dryers (as I’ll cite below) and I did find through research a citation confirming use of asbestos in some dryer drive belts.
However I'd be surprised to see any credible research tracing a clothes dryer belt to a significant asbestos exposure in any building. The total volume of a clothes dryer belt is very small - just inches; and at least for the dryers I've seen, the belt is not in the air path of the dryer intake nor exhaust.
Research finds discussions of asbestos in clothes dryers focuse on the washing and drying of asbestos-contaminated clothing or other textiles. See ASBESTOS TEXTILES.
More research DOES confirm that asbestos was used in some older clothes dryers from the 1940's and 1950's and possibly extending in North America at least into the late 1970's .
Asbestos use in clothes dryer belts is cited in at least this patent disclosure:
Beaumont, Ralph H., Donald R. Christie, and Okrepkie John. "Synthetic dryer belt." U.S. Patent 3,323,226, issued June 6, 1967.
Excerpt: In addition, even though dryer belts of the type used hereto frequently included asbestos or other heat resistant fibers, their resistance to the heat from the dryer drums in many cases proved deficient. Furthermore, difiiculties frequently were encountered heretofore in the joining of the ends of the belts to provide an endless construction.
Asbestos used around electrical components in clothes dryers is cited in at least this patent:
Colby, Weston Steward. "Fluid conductor and lint collector for clothes drier." U.S. Patent 2,722,751, issued November 8, 1955.
Excerpt: This heating element is preferably tightly wound in an open spiral to cover substantially the entire outer periphery of the imperforate cylindrical wall 27, and a thin layer of electrical insulation 38, such as, for example, asbestos or the like, is placed therebetween to prevent electrical contact with the drum and the opposite or free ends 39.
Asbestos was used in some clothes dryers as insulation around a combustion chamber (presumably gas-fired clothes dryers) and may have also been used around electrical components in electric clothes dryers.
Asbestos used in clothes dryer felt - felt often used to seal drum to cage, is cited in this patent:
Santos, John RL. "Dryer felt." U.S. Patent 2,854,032, issued September 30, 1958.
Excerpt: Such felts are at times 300 inches wide and of very considerable length, so that lengthwise as well as crosswise they must be quite strong.
They have usually been made of cotton or other vegetable fibers to give the required strength, but when they are subjected to high temperature when wet, they rapidly scorch and rot and because of this destruction they have frequently been made partly of asbestos or similar heat and acid resistant materials, retaining a large proportion of warp ends of cotton to assure the required strength.
Asbestos use in clothes dryers in other insulating applications:
Harwood, Stanley G., "Clothes-drying machine." U.S. Patent 2,385,223, issued September 18, 1945.
Excerpt: The insulating material 20 may be of any composition suitable to its purpose. A rearward wall 22 of the machine may be of any suitable material. As disclosed, the major portion of the rearward wall 22 is composed of asbestos.
Bradley Jr John, E. "Portable clothes drier." U.S. Patent 2,496,517, issued February 7, 1950.
Olthuis Eugene G "Clothes dryer." U.S. Patent 2,790,247, issued April 30, 1957. assigned to General Electric. Similar to above.
Clothes dryers eliminating use of asbestos:
Grantham, Frederick W. "Continuous laundry drying apparatus." U.S. Patent 4,015,930, issued April 5, 1977.
Cites invention features that eliminate the use of asbestos in the combustion chamber.

Asbestos-contaminated jute bags: asbestos was transported in jute or burlap bags that in turn would have been contaminated by asbestos dust, posing a hazard when the jute bags were recycled. Before 1964 when the asbestos industry transported asbestos in sacks the material was jute.
Later as the asbestos hazards were recognized industry shifted to use of non-porous bags of poly or plastic type materials to transport asbestos. Later the industry required impermeable bags be used for asbestos transport and that such bags, if re-used, were not to be cleaned by people (Ruers 2005).

Hello from the UK! I did some work at the back of my shop last year. The original building is over 100 years old - but the back was built in the later 80s. We basically took the cellulose ceiling tiles out and took the ceiling down. We then lined the new ceiling with new fibreglass rolls and boarded it up.
I remember seeing dirty fibreglass rolls when we took down the original ceiling (the place was very dusty as a result of the broken cellulose tiles and fibreglass), but i'm worried that there may have been some loose fill asbestos there as well. As I say, I can't recall seeing any, but could it have been there in a late 80's ceiling? What type of asbestos was used for loose fill insulation? Am I being silly?
Any attempt to ease my mind would be amazing! - Anonymous by private email 2016/09/22
Straight pure or "raw" asbestos as loose fill insulation would be unexpected or rare in a 1980's ceiling.
I don't have access to U.K. patents but some patent research in the U.S. gives some idea of the locations and applications of loose fill asbestos insulation - it did exist as a loose fill insulating product, typically mixed with other materials to form an insulating product.
Most common was the use of asbestos in spray-on fire-resistant coatings in buildings, used into the 1970's including in the lower floors of the now lost NYC World Trade Center. In 1971, New York City banned the use of asbestos in spray fireproofing. So upper floors of the WTC did not use that material.
For historical purposes here's some research on the use of loose fill asbestos in insulation schemes, products, and devices,
Amanda, Wenzel. "Building insulation." U.S. Patent 2,235,542, issued March 18, 1941.
Excerpt: For example, good results have been obtained by the use of paper cut, chopped, or torn into flaky fragments.
Vegetable stems, stalks, wood, leaves, and husks may also be used in fragments. And in order to render the material fire resistant, fibrous minerals, such as fragments of asbestos or asbestos paper may be mixed with any of the materials above named, or used as a substitute therefor.
A dry mixture of comminuted paper and comminuted asbestos has been found ideally suited for the purpose, such a mixture being light and downy or fluffy and containing separable fragments capable of iioating and settling lightly in the wall space.
Jacobsen, Einar. "Mechanism for applying fibers." U.S. Patent 2,550,354, issued April 24, 1951.
The present invention relates to applicators for fiber, such as asbestos, rock-wool'and fiber,- glass, ofthe character which "project the fiber in an air stream against a wall, ceiling or other surface, for the purpose of acoustical treatment, fireproofing or the like.
Barnett, Irvin, and Sidney Speil. "Handleable heat insulation shapes." U.S. Patent 3,055,831, issued September 25, 1962.
The handleable insulating shapes made according to our invention, however, may be prepared to exhibit the converse of this general consideration. For example, a bonded handleable rigid block of 10 pounds per cubic foot density comprising 5% by Weight of phenolaldehyde resin, 5% amosite asbestos fibers, and by weight of a mixture of 9 parts by weight of silica aerogel of approximately Voids by volume, and 1 part carbon black of finer than millimicrons particle size, was tested to have a K factor of 0.14 at F. mean.
A bulk mixture of the same pro portions of silica aerogel and carbon black of the type and in the proportion used in molding the bonded shape, was vibrated to a density of 10 pounds per cubic foot and tested to have a K factor of 0.18 at 150 F. mean.
The asbestos fiber of the block would also increase the solids conductivity, and would thus be expected to increase the K of the consolidated loose mass. It will be appreciated that a loose mass including fiber could probably not be vibrated to such density and retain homogeneity.
Mcdermott, Paul F. "Method anx." U.S. Patent 2,425,293, issued August 12, 1947.
The filling suitably comprises asbestos fiber ofknown I type such as Amosite fiber, although other asbestos fibers, mineral wool fibers, glass fibers and'- the like may be used.

See for example the law case cited below. However a careful read of the material makes clear that in the case I cite, the veteran had significant health risks associated with other work, habits, and materials, including smoking and including working with asbestos-containing brake linings - a job in my opinon much more likely to have exposed the vet to respirable asbestos-containing dust particles.
Anyone who worked on cars in the 1960's including brake jobs probably saw people using high pressure compressed air to blow off dust when working on those components.

Question: did people make pillow cases out of asbestos transport sacks ?
(May 19, 2016) john said:
I heard that the sacks that were used to transport asbestos were re-purposed because of how soft the material was, into pillow cases. the story i was told, sacks of asbestos were transported via railroad (turn of the 19th century through the '30s?) and when the asbestos was emptied out for manufacturing a product, the sacks would be thrown away, folks would latch onto the sacks, wash them and then sew them into pillow cases. true?
Reply: no evidence of asbestos pillow cases but jute bags were used to transport asbestos mateirals
Well that's interesting, or as the Poughkeepsie police told our friend Anna when she said that she thought the cops ought to make the train engineer stop blowing his whistle when approaching the railroad crossing .... "Well that's one I haven't heard before".
I have not found an authoritative source to confirm the asbestos pillow-case legend. Before 1964 when the asbestos industry transported asbestos in sacks the material was jute - hardly something you'd use as a pillow case. Think "burlap bags". While jute (burlap) would make a nasty pillow case, there are indeed research articles reporting on asbestos hazards associated with re-use or recycling of jute bags that were used for asbestos transport.
A search using Google Scholar, for "asbestos pillow case" did not find any research articles on that matter.
And I'm not aware of pillow-case sized sacks used to transport asbestos. Certainly they don't make even a cameo appearance in Rosato's text describing that industry.
Do you think this asbestos pillow-case is more of an urban legend? Or perhaps it's the jute bag asbestos history that fed the pillow case story.
Finally, if you or someone you know has an antique pillow case dating from before 1986 and are nervous about it, I would throw it out.

Asbestos in Plaster and stucco, includes Chrysotile asbestos.
Some plaster products may also contain tremolite (a form of amphibole asbestos) as an inadvertent contaminant from asbestos mining of chrysotile, and also they may include vermiculite that, depending on where it was mined, also contains asbestos (Libby).
Because plaster was added to various wallboard products and drywall to improve its water resistance or fire resistance, in turn that means that additional drywall products manufactured between 1920 and 1978 or later may also contain both crysotile and tremolite asbestos.
Asbestos was used as an ingredient in some plaster applications.
Asbestos was used in decorative plaster cornices, trim, ceiling medallions
Asbestos was used also in acoustical plaster both as a direct asbestos additive and as an asbestos contaminant in plasters to which vermiculiet or "Zonolite" were added to produce a light-weight plaster having good acoustical properties.
Asbestos was used in plaster designed to have a high resistance to fire.
Asbestos was used in plaster additives to gypsum board or "drywall" products to improve its moisture resistance (such as bath tile backer board) and to meet gypsum board fire resistance standards such as ASTM C630/C630M-03e1 Standard Specification for Water-Resistant Gypsum Backing Board (Withdrawn 2005 and replaced by ASTM C1396/C1396M)

Asbestos in ships lanterns: (possibly, but no record found to date - July 2016)
Question: Could old ships lanterns contain a fibrous asbestos product?
2016/07/22 Could old ships lanterns contain a fibrous asbestos product?
I was given a Murray anchor ships lantern (looks like galvanised with brass hinges) which I have been sanding and in the outer annular space at the top, I've pulled out a rusty brown coloured fibrous material.
I don't know the date of manufacture of the lamp, might be early 20th century. do you know whether asbestos was used in these lamps? - Anonymous by email request.
Reply: asbestos in R.C. Murray Ships Anchor lanterns and masthead lanterns ?
Certainly asbestos in form of paste, sealant, paper insulation and rope type gaskets appeared in many old products where fire, air leaks, or heat were concerns.
RC Murray Ships Anchor lanterns were produced in the 1850's and later, in Glasgow, Scotland. I looked at some photos of R.C. Murray Ships Anchor lanterns and masthead lanterns made of copper as well as galvanized steel and didn't see any obvious gasket or heat insulating materials, though the photos won't of course show every component.
If on your RC Murray lantern you see suspect material, you might use the page bottom CONTACT link to send me some sharp photos of the lantern and the parts and components of concern. Photos are not a substitute for a test by a certified asbestos test lab, but together we might recognize other materials.
At www.bl.uk/britishlibrary/~/media/subjects%20images/business/british_patents.pdf you can find information about how to access Scottish patents.
There are patent numbers on some of the RC Murray lanterns; armed with the patent number if you can find the actual patent you can read about the construction and materials used in the lantern as it was originally designed. However you'd have to probably ask for help as the Scottish patents from the 1850's do not appear to be online.
I can't see an obvious asbestos gasket or similar product in your photos [sent later by private email] but I'm not expert on these Lanterns. Asbestos was very widely used in thousands of products where fire resistance was important.
I suspect from the size of the lantern that unless you uses a power tool and inhaled sanding dust, it's not likely that you could have created a substantial concern IF asbestos insulation was in the lamp.

Asbestos skim coats: probably referring to thin coatings of asbestos paint or asbestos paste on surfaces to cover imperfections, to provide a desired texture, or as a fire-resistant coating.
Asbestos sound insulating materials: asbestos was included in panels or board products as well as in paints all used as sound isolation or sound transmission reduction products such as asbestos-containing ceiling, wall or floor panels used in construction of buildings and also in vehicles where it was also intended for improved fire protection, such as along with hollow wood floor panels in early aircraft.

Asbestos content in talc, talcum powder, baby powder. Asbestos occurs naturally in some talc deposits.
Note that talc itself is likely to be a respiratory and health hazard.
Some scholarly studies by experts, talcum powder might cause cancer in the ovaries if the powder applied to the genital area moves through the vagina, uterus, and fallopian tubes to the ovary. However experts disagree and litigation on the hazards of talcum powder has produced varying judgements to date (Fall 2017).

Asbestos in wallpaper products
Question: does old wallpaper contain asbestos?
2016/08/28 Savannah said:
I live in a 1920s home and noticed the wallpaper detaching from the plaster wall. I started pulling it off put realized it may contain asbestos. Anyone have experience, should I be concerned?
Reply: possibly in special circumstances
Watch out, Savannah. In addition to possible asbestos in some old wall coverings, some old wallpapers, particularly ones with green in the pattern, contained arsenic.
Previuosly we had not specifically listed "asbestos containing wallpaper" in this index to asbestos products, but such products existed, particularly where an insulating or strengthening fiber was wanted or where fire resistance was a concern.
Keep in mind that asbestos may be present in some plaster and gypsum products found beneath wallpaper too.
