Asbestos in Old Hair Dryers, Toasters, and Household Appliances
Some hair dryers, toasters, irons, and other pre-1980s appliances used asbestos for heat insulation. Learn which items are affected and what to check before you use one.
Last updated:
Yes, some household appliances made before the early 1980s contain asbestos. Manufacturers used it as a cheap, effective heat-resistant insulator around motors, heating coils, and wiring. Handheld hair dryers are the best-documented case: the Consumer Product Safety Commission found asbestos fibers released from some models in 1979 and pushed manufacturers to reformulate. Toasters, clothes irons, and a handful of other small appliances from the same era used similar insulation. The risk comes from damaged or worn parts releasing fibers, not from an appliance simply sitting in a drawer.
Why Appliances Used Asbestos
Small appliances with heating elements need insulation that can handle sustained heat without breaking down, catching fire, or transferring heat to the housing where a person's hand rests. Asbestos was cheap, fire-resistant, and easy to mold into pads, wraps, and gaskets. Through the 1960s and 1970s, manufacturers used it in:
- Heat shields around motor housings
- Insulating pads and gaskets near heating coils
- Wire and cord insulation in some models
- Backing material behind toaster heating elements
None of this was disclosed on packaging. There was no regulatory requirement to label it, and most consumers had no reason to ask.
Hair Dryers: The Best-Documented Case
Handheld hair dryers are the appliance most directly tied to asbestos exposure, and the history is well recorded. In 1979, the CPSC tested a sample of hair dryers and found that several models used asbestos as a heat shield around the motor. Airflow through the vents could carry loose fibers into the breathing zone of the person using the dryer. The finding led to a public health advisory and a shift by manufacturers toward asbestos-free insulation.
Dryers made after the early 1980s are very unlikely to contain asbestos. A dryer inherited from a relative, found at a thrift store, or stored in an attic from before that period is the one to treat with caution, especially if the housing is cracked or the vents show visible debris.
Toasters, Irons, and Other Heating Appliances
Toasters from the mid-20th century sometimes used asbestos-based insulation behind the heating elements or as a backing board inside the housing. This is separate from the asbestos-containing insulation used in home heating systems, but the underlying reason is the same: asbestos handled sustained heat better than most alternatives available at the time.
Clothes irons from the same period occasionally used asbestos pads inside the base plate to manage heat between the soleplate and the housing. Ironing board covers and pads are a related but separate item: some older covers used asbestos-treated fabric or padding specifically because irons ran hot enough to scorch ordinary cotton.
Other small appliances from the pre-1980 era, including some popcorn poppers, percolators, and portable space heaters, used asbestos gaskets or insulating pads in similar locations. Not every unit from this period contains asbestos. Formulations varied by manufacturer and by model year, and there is no single visual marker that confirms it either way.
How to Tell If Your Old Appliance Contains Asbestos
There is no reliable way to identify asbestos in an appliance by sight. A gray or off-white fibrous pad, a woven insulating wrap around a heating element, or a fibrous backing board behind a toaster's coils are all reasons for caution, but none of them confirm asbestos content on their own.
What does raise the likelihood:
- The appliance was manufactured before 1980
- It has a visible heat shield, pad, or wrap near the motor or heating element
- The housing or insulation is cracked, chipped, or crumbling
- It came from an estate, an antique shop, or long-term storage with no manufacture date available
If you plan to disassemble or repair an appliance like this, treat any fibrous insulating material as a potential hazard until tested.
Is It Safe to Keep Using an Old Appliance?
Intact asbestos-containing material inside a sealed appliance housing generally poses low risk during normal use. The hazard comes from disturbance: a cracked heat shield, a broken housing that exposes internal insulation, or physical damage from a drop. Repairing, disassembling, or attempting to clean the interior of an old appliance without knowing what the insulation is made of creates the greatest risk of releasing fibers.
The EPA notes that asbestos fibers become a health concern primarily when materials are damaged or disturbed and fibers become airborne. A working vintage appliance that has never been opened up is a different risk profile than the same appliance after a repair attempt or a drop that cracked the casing.
Given the age of these appliances, most have long outlived their practical use. Retiring an old hair dryer, toaster, or iron rather than continuing to run it is a reasonable choice independent of the asbestos question.
What to Do If You Suspect Asbestos
If an old appliance is damaged and you can see fibrous material inside, do not vacuum it, sweep it, or attempt to clean it with a household vacuum. Standard vacuums do not capture asbestos fibers and can spread them further.
Bag the item in plastic, keep it out of household traffic areas, and contact your local hazardous waste program for disposal guidance. Many municipalities have specific rules for disposing of items suspected of containing asbestos. Do not put a damaged appliance suspected of containing asbestos in regular curbside trash.
If you want confirmation before disposal, a small sample of the insulating material can be submitted to an NVLAP-accredited laboratory through a mail-in test kit. Results typically take three to five business days.
Frequently Asked Questions
Did all old hair dryers contain asbestos?
No. Only some models made before 1979 used asbestos as a heat shield around the motor. The CPSC's 1979 findings covered a sample of products on the market at the time, not every hair dryer manufactured. Dryers made after the early 1980s are very unlikely to contain asbestos.
Can I still use a vintage toaster or iron I inherited?
If the housing is intact with no cracks, chips, or exposed internal material, the risk during normal use is low. The concern arises if the appliance is damaged, disassembled, or repaired without knowing what the internal insulation contains.
How do I know if my appliance's insulation is asbestos or just fiberglass?
You cannot tell by sight. Fiberglass and asbestos insulation can look similar, gray or off-white and fibrous. A lab test is the only reliable way to distinguish them.
Is it dangerous to throw an old asbestos-containing appliance in the trash?
If the appliance is damaged and insulation is exposed, yes, this can release fibers into the waste stream and expose sanitation workers. Bag it, keep it sealed, and check with your local hazardous waste disposal program before discarding it.
Where can I learn more about asbestos in other household products?
The EPA's asbestos program page and the ATSDR both maintain background on asbestos-containing consumer products and historical use patterns.
