Which encapsulation type penetrates the ACM?

Bridging Penetrating Sealing Coating

Correct Answer:

Penetrating

Explanation:

Penetrating encapsulation goes into the material itself, soaking into the asbestos-containing material and binding the fibers from within to form a durable barrier. This stops fibers from becoming airborne even if the surface is disturbed. Bridging encapsulation sits on the surface and forms a film that bridges gaps between fibers without entering the substrate, so it can be less reliable if the surface deteriorates. Sealing or coating treatments also create a surface film but do not immobilize fibers inside the material in the same way as penetration, so they may not prevent fiber release under damage. Because the question asks which encapsulation type penetrates the ACM, the penetrating encapsulant is the one that penetrates.
