When is enclosure primarily used in asbestos abatement?

Enclosure is primarily utilized in asbestos abatement scenarios where the asbestos-containing material (ACM) is located in a small area and disturbance is unlikely. This method involves constructing a physical barrier around the ACM to contain any potential release of asbestos fibers. By enclosing the material, the risk of exposure is minimized while allowing work to proceed without immediate removal of the ACM.

This approach is particularly effective in situations where the asbestos material is in good condition and not friable, meaning it is less likely to crumble and release fibers into the air. The intent is to manage the ACM safely without unnecessary disruption, while also maintaining compliance with regulations that aim to protect health and safety.

In contrast, instances where ACM is likely to be disturbed, found in large open areas, or where immediate removal is considered necessary for safety may call for different strategies, such as removal or more aggressive containment measures.
