What does "encapsulation" mean in terms of asbestos management?

Encapsulation refers to the application of a sealant over asbestos materials to prevent the release of fibers into the environment. This method is often used when it is determined that removal is not necessary or feasible. The sealant works by binding the asbestos fibers together, thereby minimizing the potential for disturbance and exposure.

By sealing the asbestos, it creates a barrier that reduces the likelihood of fibers becoming airborne, which can pose health risks to workers and occupants in the vicinity. This method is generally preferred in situations where the asbestos material is in good condition and undisturbed, providing a safer alternative to removal.

The other options do not accurately define encapsulation. Complete removal of asbestos represents a more invasive and complex procedure, while simply painting over asbestos materials does not provide the same protective measures that encapsulation does. Wrapping asbestos materials in plastic could be considered a form of containment rather than encapsulation, which specifically involves the use of a sealant designed for this purpose.
