What does enclosure in asbestos abatement mean?

Enclosure in asbestos abatement refers to placing a physical barrier between asbestos-containing materials (ACMs) and the surrounding environment. This method is designed to prevent the release of asbestos fibers into the air, thereby minimizing the risk of exposure for individuals in the vicinity. Enclosure can involve techniques such as constructing walls or installing protective coverings around ACMs, which effectively contain any potential asbestos hazards by isolating them from areas where people may be present.

This approach is particularly useful when removal of the asbestos is not feasible due to reasons such as structural integrity or cost. By creating a physical barrier, the enclosure method safeguards the health of occupants in a building while allowing for the continual use of the space under controlled conditions.

In contrast, sealing with tape, removing all ACMs, and continuously monitoring air quality each represent different strategies in the management of asbestos, but they do not specifically involve the concept of creating a barrier to isolate the hazard as enclosure does.
