Asbestos is extremely common in the built environment. Any home, school, or commercial building constructed before 1980 has a reasonable chance of containing asbestos in at least one material, from floor tiles to pipe insulation to textured ceilings. At its peak in 1973, the United States consumed 794,000 metric tons of asbestos fiber in a single year, and much of that material is still in place in older structures today.
Globally, asbestos hasn’t gone away either. Roughly 1.3 million metric tons were mined worldwide in 2022, and demand continues, particularly for construction materials in Asia. The U.S. didn’t finalize a ban on its last remaining uses until March 2024.
How Common Asbestos Is in Homes
Homes built between the 1930s and late 1970s are the most likely to contain asbestos. During those decades, asbestos was added to dozens of ordinary building materials because it was cheap, fireproof, and durable. If your home falls in that era, asbestos could be in places you’d never suspect: the adhesive under vinyl floor tiles, the joint compound between sheets of drywall, the insulation wrapped around steam pipes, or the textured “popcorn” coating on ceilings.
The Consumer Product Safety Commission identifies a long list of residential materials that commonly contained asbestos, including vinyl floor tiles and their backing, cement roofing shingles and siding, insulation blankets around boilers and furnace ducts, soundproofing sprayed on walls, door gaskets in wood stoves, and even artificial ashes sold for gas fireplaces. Homes built between 1930 and 1950 are especially likely to have asbestos insulation.
The critical detail is that asbestos in good condition, left undisturbed, generally doesn’t release fibers into the air. The risk spikes when you renovate, drill, sand, or tear out old materials. That’s why a house built in 1965 can be perfectly safe to live in but hazardous to remodel without testing first.
Where Asbestos Occurs Naturally
Asbestos isn’t only a manufactured problem. It’s a naturally occurring mineral found in rock formations across the country. The U.S. Geological Survey maps two principal belts of chrysotile asbestos (the most common type): an eastern belt running from Maine to Alabama and a western belt stretching from Washington to California. Both follow zones where certain types of rock were pushed up through the earth’s crust hundreds of millions of years ago. Smaller deposits of a different asbestos variety, found in limestone formations, are scattered across Arizona.
In these areas, construction, road grading, or even wind erosion can disturb asbestos-bearing rock and release fibers into the air. Parts of El Dorado County, California, for example, have been the subject of public health advisories for exactly this reason. If you live in a region with known serpentine rock formations, local health agencies may have specific guidelines for soil disturbance.
Products That Still Contain Asbestos
Until very recently, asbestos remained legal in several product categories in the United States. Before the EPA’s 2024 ban took effect, ongoing uses included chlor-alkali diaphragms (used in chemical manufacturing), sheet gaskets, oilfield brake blocks, aftermarket automotive brakes and linings, other vehicle friction products, and various industrial gaskets. The Minnesota Department of Health also notes that trade agreements have introduced asbestos-containing products from other countries into the American marketplace.
The March 2024 EPA rule bans chrysotile asbestos, which is the only form still imported into or used in the U.S. Some of these bans kicked in immediately, while others phase in over years. Vehicle friction products and oilfield brake blocks were banned six months after the rule took effect. Most sheet gaskets face a two-year phaseout. The longest exemption extends to 2037 for a Department of Energy nuclear site in South Carolina. The eight remaining chemical plants that use asbestos diaphragms must convert to alternatives on a staggered timeline, with the last facilities completing the switch within 12 years.
In older buildings, the list of materials that may contain asbestos is staggeringly long. It includes ceiling tiles, chalkboards, electrical panel components, elevator brake shoes, vermiculite attic insulation, window glazing, vinyl wall coverings, roofing felt, fire doors, and laboratory countertops, among many others. You cannot identify asbestos by looking at a material. Testing by an accredited lab is the only reliable method.
Global Production Today
While more than 60 countries have banned asbestos, the mineral is still actively mined and traded. In 2022, global mine production totaled an estimated 1.3 million metric tons. Russia led production at 700,000 metric tons, followed by Kazakhstan at 230,000, Brazil at 190,000, and China at 130,000. Global consumption has held relatively steady between 1.1 and 1.3 million tons per year since 2015, driven largely by demand for cement pipes and roofing sheets in Asia.
To put that in perspective, the U.S. alone consumed 794,000 metric tons at its 1973 peak. The world is still producing and using more asbestos annually than America did during its heaviest consumption year.
Who Faces the Greatest Risk Today
The people most likely to encounter asbestos now are those who work in or around older buildings and infrastructure. Construction workers renovating structures built before the 1980s face ongoing exposure risks. Plumbers handling old cement pipes, electricians crawling through attics with deteriorating insulation, and insulators working in aging factories or power plants are all in high-risk categories.
Firefighters face a particularly acute risk. When older buildings burn, asbestos fibers become airborne. Firefighters are twice as likely to develop mesothelioma as the general population. According to the International Association of Fire Fighters, 80% of those added to the Fallen Fire Fighter Memorial in 2025 died from occupational cancer.
Military veterans carry a disproportionate burden as well. About 33% of mesothelioma patients are veterans, a reflection of how heavily asbestos was used in naval vessels, barracks, and military equipment through the mid-20th century. Navy personnel were at especially high risk because ships were built with asbestos insulation in nearly every compartment.
Mechanics also remain at risk when working on older vehicles. Brake pads, clutch facings, and other friction materials manufactured before the early 1980s commonly contained asbestos, and some aftermarket parts continued to until the 2024 ban.
The Health Toll
Asbestos exposure causes mesothelioma, a cancer of the lining around the lungs or abdomen that is almost exclusively linked to asbestos. In 2022, 2,669 new cases were reported in the United States. Mesothelioma typically appears 20 to 50 years after exposure, which means cases diagnosed today often trace back to workplaces and buildings from the 1970s and 1980s.
Beyond mesothelioma, asbestos exposure also causes lung cancer and asbestosis, a chronic scarring of lung tissue. The long latency period means the full health impact of past exposure is still unfolding, and people who encountered asbestos decades ago may not yet have developed symptoms. There is no safe level of asbestos exposure, though risk increases with the intensity and duration of contact.
