When is Asbestos Dangerous?

Asbestos becomes dangerous when microscopic fibers are released into the air and inhaled. These fibers are extremely small and cannot be seen, smelled, or tasted. Once airborne, asbestos particles can remain suspended in the air for long periods and may be inhaled by anyone nearby.


Many homes and commercial buildings built before the 1980s contain materials that may include asbestos. When those materials are disturbed during renovations, demolition, or damage, asbestos fibers can become airborne and create a potential health hazard.


HB Environmental Services helps homeowners, contractors, and property managers throughout the St. Louis area identify and safely address asbestos-containing materials before they become a serious risk.

When Does Asbestos Become Dangerous?

Asbestos becomes dangerous when materials containing asbestos are disturbed, damaged, or deteriorating.


When asbestos-containing materials remain intact and undisturbed, they often pose minimal risk. However, once fibers are released into the air, they can be inhaled and become trapped in the lungs.


Long-term exposure to asbestos fibers has been linked to several serious health conditions, including:


• Mesothelioma
• Lung cancer
• Asbestosis
• Pleural thickening


These diseases may take 20 to 40 years to develop after exposure.

Situations Where Asbestos Becomes Dangerous

Asbestos exposure most commonly occurs when building materials are disturbed. Some of the most common situations where asbestos becomes dangerous include:


• Home renovation projects
• Removing flooring materials
• Demolition work
• Cutting or drilling into walls or ceilings
• Water damage that deteriorates insulation
• Fire damage to building materials
• Damaged pipe insulation in basements or mechanical rooms


These activities can release asbestos fibers into the surrounding air.

Friable vs Non-Friable Asbestos

Friable vs Non-Friable Asbestos

Asbestos materials are often categorized as friable or non-friable, which affects how easily fibers can become airborne.


Friable Asbestos

Friable asbestos materials can easily crumble or break apart when disturbed. These materials are considered the most hazardous because fibers can be released easily.

Examples include:


• Pipe insulation
• Boiler insulation
• Spray-applied fireproofing
• Certain ceiling textures

Friable vs Non-Friable Asbestos

Asbestos materials are often categorized as friable or non-friable, which affects how easily fibers can become airborne.


Non-Friable Asbestos

Non-friable asbestos materials are more solid and typically do not release fibers unless they are cut, sanded, or broken.

Examples include:

• Vinyl asbestos floor tile
• Black mastic adhesive
• Asbestos cement siding
• Roofing materials


Even though these materials are more stable, they can still become dangerous during renovations or demolition.

Can You See or Smell Asbestos?

No. Asbestos fibers are microscopic and cannot be seen without specialized equipment.


They also have no smell or taste, which means people can be exposed without realizing it.


Because asbestos cannot be identified visually with certainty, professional testing is often necessary to confirm whether materials contain asbestos.

When Should You Test for Asbestos?

You should consider professional asbestos testing if:


• Your home or building was built before 1980
• You are planning a renovation project
• You discover old floor tiles or adhesives
• You find deteriorating pipe insulation
• You suspect popcorn ceilings may contain asbestos
• You are preparing for demolition work


Testing is the only reliable way to determine whether materials actually contain asbestos.

What Should You Do If You Suspect Asbestos?

If you believe a material may contain asbestos, do not disturb it.


Cutting, sanding, drilling, or breaking the material can release fibers into the air and increase the risk of exposure.


Instead, contact a professional asbestos company that can inspect the material, collect samples if necessary, and determine whether removal or containment is required.
