What Are the Health Risks Associated with Asbestos Exposure?

Asbestos exposure causes mesothelioma, lung cancer, and asbestosis. Montana homes can especially at risk. Learn the real dangers and who to call.

The Diseases That Follow You for Decades

Asbestos exposure doesn’t hurt you right away. That’s what makes it difficult to combat.

Inhaled fibers lodge deep in lung tissue and sit there, sometimes 20 to 50 years, before triggering disease.

Mesothelioma

A rare, aggressive cancer of the lining around the lungs and abdomen. The National Cancer Institute classifies asbestos as a known human carcinogen. According to the CDC, 2,669 new mesothelioma cases were reported in the U.S. in 2022 alone.

Asbestosis

Chronic scarring of lung tissue from repeated fiber inhalation. Breathing becomes progressively harder. There is no cure, only management.

Lung Cancer

Up to 15% of all lung cancer cases are linked to asbestos exposure, according to the International Journal of Environmental Research and Public Health.

Key Takeaway: These diseases develop quietly over decades. By the time symptoms appear, exposure happened long ago, often inside a building you still own.

Why Montana Is Ground Zero for This Conversation

Libby, Montana, is the most catastrophic asbestos contamination event in U.S. history. W.R. Grace operated a vermiculite mine there from 1963 to 1990, knowing the ore contained tremolite-actinolite asbestos. An estimated 694 Libby residents died from asbestos-related disease. Over 2,400 more were diagnosed.

In 2009, the EPA declared its first and only public health emergency over an environmental disaster, in Lincoln County.

That mine supplied vermiculite insulation, sold under the Zonolite brand, to homes across the country. If you have loose-fill attic insulation in an older Montana home, it could use testing.

Key Takeaway: Montana’s asbestos problem isn’t only historical. Older structures throughout Missoula, Great Falls, Butte, Helena, and Bozeman still contain asbestos-containing materials.

Where Asbestos Hides in Older Buildings

Common Locations in Pre-1980 Structures

  • Pipe and duct insulation (often wrapped in gray or white tape)

  • Floor tiles and the adhesive beneath them

  • Textured ceiling coatings and popcorn ceilings

  • Roofing shingles and siding panels

  • HVAC duct insulation

  • Vermiculite attic insulation (common in homes built before 1980)

Asbestos-containing materials are not dangerous when left undisturbed. The hazard activates the moment fibers become airborne, during cutting, drilling, sanding, or demolition.

Key Takeaway: Testing by a certified inspector is the only reliable method.

Who Do You Call in Montana?

Other contractors operating in Montana, including Safetech Inc. and Absaroka Abatement, do so-so asbestos work. Verify any contractor’s current accreditation status through the Montana DEQ database at deq.mt.gov. Credentials expire annually and must be renewed. 

Abatement Contractors of Montana (ACM), headquartered in Missoula, holds active Montana DEQ, OSHA, and EPA certifications. ACM’s team has many years of combined field experience in hazardous material remediation across residential, commercial, federal, and industrial projects throughout the Mountain West.

One verified Google reviewer put it plainly: “ACM was wonderful to work with, and could not have made the process more smooth on us.”

FAQ

Can asbestos exposure happen from a single incident?

Yes. Even short-term high-intensity exposure carries real risk, particularly with amphibole fiber types like tremolite.

How do I know if my Montana home has asbestos?

You don’t without testing. Homes built before 1980 are high-probability candidates. A certified inspector collects samples for lab analysis.

Is asbestos still legal in the U.S.?

The EPA banned new uses of chrysotile asbestos in 2024, but the ban is under ongoing legal challenge and existing materials in older buildings remain in place nationwide.

What is mesothelioma’s survival rate?

Median survival is typically 12 to 21 months following diagnosis, which is why early identification and limiting further exposure matters a lot.

Can family members get sick from asbestos brought home on work clothes?

Yes. The NCI confirms secondary exposure from fibers transferred on clothing, skin, and hair is a documented cause of mesothelioma in family members.

Does homeowner’s insurance cover asbestos removal?

Most policies exclude abatement unless it results from a covered loss event. Improper DIY removal or use of unlicensed contractors can void claims entirely.

How long does professional asbestos abatement take?

Residential projects typically run one to three days depending on material volume and containment requirements. ACM provides site-specific timelines after inspection.
