What are the two types of encapsulants used in asbestos management?

The correct answer identifies the two types of encapsulants as bridging and penetrating. In the context of asbestos management, encapsulants are materials used to contain asbestos and prevent the release of fibers into the air.

Bridging encapsulants typically form a thick layer over the surface of the asbestos-containing material, creating a barrier that seals it off from the environment. These products are designed to adhere strongly to surfaces and can be used in situations where the asbestos material is intact but needs to be managed to prevent exposure.

Penetrating encapsulants, on the other hand, are formulated to seep into the material and bind the asbestos fibers together. This type of encapsulant may be utilized when the asbestos material is friable or damaged, helping to stabilize the material and prevent the release of asbestos fibers.

Together, these two types provide a comprehensive approach to managing asbestos risks by ensuring that the problem is addressed effectively, whether the asbestos is intact or needs additional stabilization.
