Often when renovating or demolishing a commercial property a permit inspector will ask for your Asbestos Survey. But, What is Asbestos?
Asbestos is a group of naturally occurring silicate minerals known for their heat resistance, durability, and insulating properties. It was widely used in construction, insulation, roofing, flooring, and fireproofing materials until its health risks became well-known.
Health Risks of Asbestos Exposure
When asbestos fibers become airborne and are inhaled, they can cause serious health problems, including:
- Asbestosis – Scarring of lung tissue leading to breathing difficulties.
- Lung Cancer – Increased risk, especially in smokers.
- Mesothelioma – A rare, aggressive cancer affecting the lining of the lungs and abdomen.
- Pleural Disease – Thickening of lung membranes, reducing lung function.
- Because of these risks, asbestos abatement (safe removal and containment) is strictly regulated.
How to Professionally Abate Asbestos
Asbestos abatement must be handled by licensed professionals following strict safety protocols to minimize exposure. The process typically includes the following steps:
- Inspection & Testing
Asbestos Inspection: A certified asbestos professional inspects the building to identify materials that may contain asbestos.
Sample Testing: Suspect materials are tested in a certified laboratory to confirm the presence of asbestos.
Common asbestos-containing materials include:
✔ Insulation (pipes, boilers, HVAC)
✔ Floor tiles & adhesives
✔ Roofing shingles
✔ Popcorn ceilings
✔ Cement panels & siding
- Developing an Abatement Plan
A detailed abatement plan is created based on inspection results.
Compliance with EPA, OSHA, and local regulations is ensured.
Necessary permits and approvals are obtained before work begins.
- Preparing the Work Area
Sealing the Area: Plastic sheeting and negative air pressure systems prevent asbestos fibers from spreading.
Decontamination Units: Workers use special entry/exit decontamination chambers.
Warning Signs: Clearly mark the hazardous area to keep unauthorized personnel out.
- Removal & Containment
Depending on the condition and location of asbestos, professionals use one of three methods:
- a) Encapsulation (Sealing In Place)
Asbestos is coated with a special sealant to prevent fiber release.
Used when removal is not feasible or necessary.
- b) Enclosure (Covering)
A protective barrier (such as drywall or metal sheeting) is built over asbestos-containing materials.
Prevents fiber release without disturbing the asbestos.
- c) Removal (Full Abatement)
The most hazardous and complex method.
Asbestos-containing materials are carefully removed using wetting agents to reduce fiber release.
Materials are double-bagged in labeled, airtight containers.
- Proper Disposal of Asbestos Waste
Sealed asbestos waste is transported to EPA-approved hazardous waste facilities.
Specialized containers prevent asbestos fibers from contaminating the environment.
- Air Monitoring & Clearance Testing
Air sampling and clearance testing ensure no airborne asbestos remains after abatement.
The work area is only reopened after passing EPA-approved air quality tests.
Safety Measures for Asbestos Abatement
✔ Personal Protective Equipment (PPE): Respirators, disposable coveralls, gloves, and boot covers.
✔ HEPA Filters: Used in vacuums and air scrubbers to capture asbestos fibers.
✔ Negative Air Pressure Systems: Prevents asbestos from escaping the work zone.
✔ Proper Training & Certification: Only licensed professionals should handle asbestos removal.
Asbestos abatement is a highly regulated and hazardous process that requires professional handling. The safest way to deal with asbestos is to hire licensed abatement specialists who follow proper containment, removal, and disposal procedures. Attempting DIY removal is extremely dangerous and illegal in many areas.
