How to Get Rid of Asbestos?

Assessing Friability and Deciding Between Removal and Encapsulation

The initial phase of getting rid of asbestos is determining whether complete physical extraction is truly necessary. Environmental agencies, including the EPA, emphasize that undisturbed, undamaged asbestos-containing materials are often safer left alone or encapsulated than disturbed. Non-friable products like vinyl composition floor tiles or exterior cement transite siding do not emit fibers while solid. In such scenarios, encapsulation—such as applying an elastomeric sealant or covering the floor with new floating laminate—permanently locks fibers in place with zero airborne danger.

Physical removal becomes non-negotiable when materials are friable (such as deteriorated popcorn ceilings, loose vermiculite attic insulation, or frayed pipe elbow lagging) or when planned structural renovations will inevitably cut, saw, or shatter the hazardous surfaces. Once removal is designated, property owners must understand that standard household vacuum cleaners, domestic fans, and casual sweeping must never be employed, as these actions merely aerosolize deadly microscopic dust.

Compare the tactical differences, risk profiles, and costs between encapsulation and full removal:

Engineering Controls: Containment Chambers and HEPA Filtration

When executing complete asbestos abatement, establishing rigorous engineering controls is paramount. Abatement technicians isolate the contaminated area from the rest of the building by hanging two layers of six-mil flame-retardant polyethylene sheeting across all doorways, windows, wall vents, and HVAC registers. An airtight three-stage decontamination chamber—comprising a dirty room, shower room, and clean room—is erected at the entrance to ensure workers can decontaminate and change before leaving the work zone.

Crucially, the workspace is placed under continuous negative air pressure utilizing industrial HEPA air scrubbers. These machines extract air from the containment chamber, pass it through certified 99.97% HEPA filters, and exhaust the clean air to the building exterior. This pressure differential ensures that if a seal breaches, ambient outdoor air rushes inward into the containment zone, preventing any escaped asbestos fibrils from migrating into occupied living areas of the property.

Safe Extraction, Waste Bagging, and Clearance Verification

The actual extraction of asbestos materials demands gentle, wet handling techniques. Workers spray all target surfaces with surfactant-amended water to saturate the fibers completely before carefully prying, unbolting, or cutting components. Saturated debris is transferred immediately into heavy, OSHA-labeled six-mil plastic bags. Heavy or sharp items like transite siding or pipe sections are double-wrapped in six-mil poly sheeting and taped securely with duct tape to prevent tearing.

Once all hazardous materials have been stripped, the entire containment zone undergoes meticulous decontamination. Technicians vacuum all framing, subflooring, and plastic barriers using certified HEPA vacuums, followed by thorough wet-wiping with clean disposable rags. After a settling period, an independent environmental consultant performs aggressive air clearance sampling using Phase Contrast Microscopy (PCM) or Transmission Electron Microscopy (TEM). Only after air samples demonstrate fiber concentrations well below 0.01 fibers per cubic centimeter is containment dismantled.
