How Is Asbestos Removed Safely?

Why Professional Removal Is Required

Asbestos removal (abatement) is one of the most heavily regulated activities in the construction industry. Improper removal can release millions of microscopic asbestos fibers into the air, creating serious health hazards for workers, building occupants, and neighboring properties. For this reason, both the EPA and OSHA impose strict requirements on asbestos abatement, and most states require contractors to hold specific licenses for this work.

Homeowners, general contractors, and unqualified workers should never attempt to remove asbestos-containing materials. The risk of asbestos exposure during improper removal is extremely high, and the resulting contamination can be difficult and expensive to remediate.

The Professional Abatement Process

Licensed asbestos abatement follows a systematic process designed to contain and minimize fiber release. The work area is isolated from the rest of the building using polyethylene plastic sheeting sealed with tape. Negative air pressure is established using HEPA-filtered air units, which ensure that any airborne fibers are drawn into the contained area rather than escaping to other parts of the building.

Workers wear personal protective equipment (PPE), including disposable coveralls, HEPA-filtered respirators, and gloves. Asbestos-containing materials are thoroughly wetted using amended water (water with a surfactant added to improve penetration) before any disturbance. Wet materials release far fewer airborne fibers than dry materials. Workers then carefully remove the wetted materials using hand tools, avoiding power tools that would generate additional dust.

Removed asbestos materials are placed in sealed, labeled polyethylene bags or containers while still wet. These containers are transported to approved hazardous waste landfills for disposal. After removal is complete, the work area is thoroughly cleaned using HEPA vacuums and wet wiping, and air monitoring is performed to confirm that fiber levels are below acceptable thresholds before the containment is removed.

Alternatives to Removal

In some cases, removal is not the safest or most practical option. Encapsulation (coating asbestos materials with a sealant) and enclosure (covering asbestos materials with a protective barrier) are approved alternatives that can manage the hazard without the risks associated with removal. These approaches are particularly appropriate when asbestos materials are in good condition and are unlikely to be disturbed.

A qualified asbestos inspector can assess the condition of materials and recommend whether removal, encapsulation, or enclosure is the most appropriate management strategy for your specific situation.

If You Were Exposed During Improper Removal

If you were exposed to asbestos during an uncontrolled removal or renovation — whether as a worker or a building occupant — inform your physician about the exposure. You may also have legal rights against the property owner, contractor, or other parties who failed to follow proper asbestos procedures. An experienced attorney can evaluate your situation and advise you about available options.
