The Science of Safe Asbestos Remediation
Asbestos removal is the most highly regulated sector of the demolition industry. Safe remediation requires specialized equipment, rigorous training, and uncompromising adherence to safety codes.
Friable vs. Non-Friable Asbestos
Non-friable (Class B): Asbestos mixed with cement or other hard bonding materials (e.g., fibro sheeting). While less likely to release fibers unless broken, it still requires licensed removal.
Friable (Class A): Asbestos in powder form or that can be crumbled by hand pressure (e.g., loose-fill insulation, pipe lagging). This is extremely dangerous and requires maximum containment.
The Removal Protocol
For Class A removals, the area is sealed with heavy-duty plastic to create a 'bubble'. Negative air pressure units equipped with HEPA filters are installed to ensure no air escapes the containment zone. Workers wear full hazmat suits and continuous airline respirators.
Clearance and Certification
Once the material is lawfully wrapped, sealed, and transported to an EPA-approved facility, an independent Licensed Asbestos Assessor visually inspects the area and conducts air monitoring. Only when the air is proven clean is a Clearance Certificate issued.
