Can You Still Be Exposed to Asbestos Today? 7 Places Where the Risk Remains in 2026

Why is asbestos still a risk if it was banned in 2024?

The EPA finalized a ban on chrysotile asbestos under the Toxic Substances Control Act in March 2024, prohibiting its use in chlor-alkali manufacturing, sheet gaskets, aftermarket automotive brake and clutch parts, and other industrial applications.^[3] This was a landmark regulatory action — but it addresses future use only. The ban does not require removal of the millions of tons of asbestos already installed in American homes, schools, offices, and industrial buildings.

The distinction matters enormously. Over 30 million U.S. homes built before 1980 contain asbestos in some form — floor tiles, pipe insulation, ceiling texture, attic insulation, roof shingles, or siding.^[1] These materials are considered safe when undisturbed. But the moment they are cut, drilled, sanded, scraped, or demolished during renovation or maintenance work, they release microscopic asbestos fibers into the air.

"People assume the asbestos problem is solved because there's a ban. But the ban only stops new asbestos from entering the country. The asbestos that's already in 30 million homes, in schools, in buildings across America — it's still there. And every time someone renovates without testing first, they risk exposure."

Where does asbestos exposure happen during home renovations?

Place 1: Older homes during renovation projects. This is the single largest source of non-occupational asbestos exposure today. Australian Mesothelioma Registry data found that 51% of patients with non-occupational exposure were exposed during major home renovations involving asbestos-containing materials. The most common materials disturbed during renovation include:

• 9-by-9-inch vinyl floor tiles — containing 15 to 26% chrysotile asbestos, manufactured by companies including Armstrong and Kentile through the 1980s
• Popcorn and textured ceilings — containing 1 to 10% chrysotile, applied as spray-on acoustic texture from the 1950s until the EPA banned spray-on asbestos in 1978
• Drywall joint compound — containing 3 to 15% chrysotile, produced by manufacturers including Georgia-Pacific, National Gypsum, and Kaiser Gypsum through 1977
• Pipe and boiler insulation — containing 15 to 100% chrysotile or amosite, manufactured by Johns-Manville and Owens Corning through the 1970s
• Cement siding and roofing shingles — containing 10 to 50% chrysotile, including the widely used Transite board manufactured by Johns-Manville

A critical regulatory gap compounds the risk: the EPA's NESHAP asbestos rules explicitly exclude single-family residential buildings, and no federal law requires homeowners to test for asbestos before renovating.^[5]

What is Zonolite vermiculite insulation and why is it dangerous?

Place 2: Attics with vermiculite insulation. Between 15 and 35 million U.S. homes contain Zonolite-brand vermiculite attic insulation, manufactured by the W.R. Grace company using ore from the Libby, Montana mine. This ore was contaminated with tremolite, a particularly hazardous amphibole form of asbestos. The insulation contains up to 5% tremolite asbestos and was installed in homes from the 1920s through 1990.^[10]

Homeowners who enter attics containing Zonolite insulation, store items on top of it, or disturb it during renovation risk inhaling tremolite fibers. The Zonolite Attic Insulation Trust was established to help homeowners cover the cost of professional removal. The EPA recommends that homeowners with vermiculite insulation assume it contains asbestos and avoid disturbing it without professional abatement.^[1]

"Zonolite insulation is in millions of attics across the country. It looks like small, accordion-shaped granules — gold, silver, or brown. If you see it in your attic, do not touch it. Do not blow additional insulation on top of it. Call a certified asbestos abatement professional."

How does asbestos exposure happen at construction and demolition sites?

Place 3: Construction, demolition, and renovation worksites. OSHA's estimate that 1.3 million workers face asbestos exposure risk refers primarily to construction and general industry workers who encounter asbestos-containing materials during their daily work.^[2] Workers in these trades face the highest current exposure risk:

• Demolition workers — tearing down pre-1980 buildings that contain asbestos in insulation, flooring, walls, and roofing
• Renovation contractors — cutting, drilling, and removing materials in older homes and commercial buildings
• Electricians and plumbers — routing wiring and pipes through walls and ceilings that contain asbestos insulation
• HVAC technicians — working around asbestos-wrapped ductwork and pipe insulation in older buildings
• Roofers — removing asbestos-cement roofing shingles and Transite panels

OSHA's construction standard at 29 CFR 1926.1101 classifies asbestos work into four tiers (Class I through IV), each with specific engineering controls, monitoring requirements, and PPE mandates. Employers who fail to comply face penalties of up to $165,514 per willful violation.^[4]

Are schools and public buildings still contaminated with asbestos?

Place 4: Schools, hospitals, and government buildings. The Asbestos Hazard Emergency Response Act (AHERA) of 1986 required schools to inspect for asbestos and develop management plans — but it did not require removal. Thousands of American schools still contain asbestos in floor tiles, ceiling panels, pipe insulation, and fireproofing materials. When these materials deteriorate or are disturbed during maintenance, they release fibers that expose students, teachers, and custodial staff.^[1]

Hospitals, courthouses, government offices, and other public buildings constructed before 1980 face the same issue. Building maintenance workers — custodians, facility engineers, HVAC technicians — are at particular risk because their daily work often involves disturbing materials in walls, ceilings, and mechanical spaces that may contain asbestos.

Can auto mechanics still be exposed to asbestos?

Place 5: Auto repair and brake work. Asbestos was a standard component in automotive brake pads, brake shoes, clutch facings, and gaskets for decades. While most domestic manufacturers switched to asbestos-free formulations by the 1990s, aftermarket brake and clutch parts containing chrysotile asbestos continued to be imported and sold in the United States until the EPA's 2024 ban took effect.^[3]

Mechanics who service older vehicles or who worked with aftermarket parts before the ban risk exposure to asbestos dust during brake and clutch repair. OSHA's general industry standard specifically addresses brake and clutch repair operations, requiring wet methods or enclosed local exhaust ventilation rather than compressed air for dust removal.^[2]

How do natural disasters and natural deposits create asbestos exposure?

Place 6: Natural disaster zones. Hurricanes, tornadoes, earthquakes, wildfires, and floods destroy buildings — and when pre-1980 structures collapse or burn, they release asbestos fibers into the environment. First responders, cleanup crews, and returning residents face significant exposure risk in disaster zones. The EPA issues asbestos advisories after major natural disasters and recommends that residents not return to damaged older homes until asbestos testing has been completed.

Place 7: Naturally occurring asbestos deposits. Asbestos is a naturally occurring mineral, and geological deposits exist across the United States. The EPA has identified naturally occurring asbestos (NOA) in parts of California, Montana, Virginia, North Carolina, and other states. Land disturbance from road construction, farming, or residential development near NOA deposits can release asbestos fibers into the air. The Libby, Montana Superfund site — where W.R. Grace mined vermiculite contaminated with tremolite asbestos — remains one of the most significant NOA-related exposure sites in American history.^[9]

"Asbestos is not just an industrial problem. It's in homes, schools, soil, and the air after disasters. Until every pre-1980 building has been tested and remediated, asbestos exposure will continue to cause mesothelioma in Americans who never worked in a factory or shipyard."

— Yvette Abrego, Senior Client Manager, Danziger & De Llano

What should you do if you think you were exposed to asbestos?

If you have been exposed to asbestos — whether through a home renovation, workplace exposure, or environmental contamination — the most important step is to tell your doctor about the exposure. Mesothelioma has a latency period of 20 to 50 years, so exposure from decades ago is relevant to your health today.^[6] Request a baseline chest X-ray or CT scan to establish a health record.

If you have already been diagnosed with mesothelioma or another asbestos-related disease, you may have legal options. Compensation is available through lawsuits against responsible companies, asbestos bankruptcy trust fund claims, and VA benefits for military veterans. The experienced advocates at Danziger & De Llano can help you understand your options.
