What are bridging and penetrating sealants?

Bridging and penetrating sealants are specifically formulated bonding agents that are applied to materials containing asbestos or to surfaces that may be disturbed during an abatement project. These sealants work by effectively encapsulating asbestos fibers, preventing them from becoming airborne and thus reducing the risk of exposure during decontamination processes.

The term "bridging" refers to how these sealants create a protective layer that bridges over asbestos-containing materials, while "penetrating" indicates the sealant's ability to penetrate into the material itself, providing a longer-lasting encapsulation. This method is particularly useful in scenarios where complete removal of asbestos may not be feasible or practical, allowing for safer management and compliance with regulations regarding the handling and containment of hazardous materials.

In contrast, the other choices relate to different contexts, such as bonding agents applied to drywall, types of insulation materials, or protective clothing, which do not accurately describe the specific function and application of bridging and penetrating sealants in asbestos management.
