What does the term 'encapsulation' mean in asbestos management?

The term 'encapsulation' in asbestos management specifically refers to the application of a sealant or a protective coating around asbestos-containing materials to prevent the release of asbestos fibers into the air. This method is particularly useful when the materials are in good condition and are not likely to be disturbed, as it allows the material to remain in place while reducing health risks associated with airborne asbestos fibers.

By sealing the asbestos, encapsulation effectively creates a barrier that prevents fibers from becoming airborne, thereby reducing the potential for exposure to individuals. This approach is often chosen in situations where removal is not feasible or when it would be more disruptive and hazardous to remove the material completely.

Other options related to removal, demolition, and monitoring exposure levels represent different aspects of asbestos management but do not define encapsulation accurately. Therefore, the definition involving the application of a sealant aligns precisely with the established practice of encapsulation in asbestos management.
