What does encapsulation involve in asbestos management?

Encapsulation in asbestos management primarily involves applying a material, such as paint or glue, to secure friable asbestos fibers and prevent their release into the air. The main goal of encapsulation is to isolate the asbestos, making it less hazardous by containing the fibers and inhibiting their ability to become airborne. This method is often preferred in situations where removal is not feasible or poses a greater risk than leaving the materials in place and managing them safely.

The other options refer to different asbestos management strategies. Complete removal involves taking out asbestos materials entirely from a structure, which can be disruptive and costly. Capping with concrete or other materials can serve as a method of containment, but it's more about physically covering the asbestos rather than securing it. Sealing off an area with plastic sheeting is a form of containment used during removal or abatement activities, not encapsulation itself. Each method has its applications and considerations, but encapsulation specifically targets the stabilization and sealing of existing asbestos to minimize exposure risk.
