What is one method of asbestos management that involves sealing materials to prevent fiber release?

Encapsulation is a method of asbestos management that involves sealing asbestos-containing materials (ACMs) with a protective coating. This technique aims to prevent the release of asbestos fibers into the air, reducing the risk of exposure to individuals in the vicinity. By encapsulating the material, it creates a barrier that keeps fibers contained and minimizes the likelihood of disturbance, which can occur due to wear, damage, or environmental factors.

This method is particularly useful for managing materials where removal is not feasible or necessary, allowing the ACMs to safely remain in place while ensuring that potential hazards are effectively mitigated. Encapsulation products can include paints, sealants, or specialized coatings that bind the fibers and prevent their dispersion.

In contrast to other methods, such as enclosure—which involves constructing a physical barrier around the ACMs—or maintenance that pertains to regularly checking the condition of the asbestos materials, encapsulation is specifically about creating a seal. Inspection is about evaluating the condition of the materials but does not actively prevent fiber release like encapsulation does.
