What does encapsulation of asbestos involve?

Encapsulation of asbestos involves placing a sealant over the asbestos material. This process is designed to immobilize asbestos fibers, thus preventing them from becoming airborne and reducing the risk of exposure. The sealant is typically a type of coating that adheres to the surface of the asbestos material, forming a protective barrier. This method is often preferred when removal of the asbestos is not feasible due to structural or safety concerns, and it allows for the asbestos to remain in place while minimizing health risks.

In contrast, complete removal of the material, covering it with new drywall, or taping the edges with plastic sheeting do not accurately represent the encapsulation process. Removal involves dismantling the asbestos material altogether, while covering it with drywall or sealing the edges with plastic sheeting may not adequately prevent fiber release or provide the same stabilization effect as a specialized encapsulating sealant. Encapsulation aims to keep the existing asbestos in a safe condition rather than altering or removing it entirely.
