What is a negative pressure enclosure?

A negative pressure enclosure is defined as an area where the air pressure is maintained lower than that of the surrounding environment. This technique is specifically utilized in asbestos-related work to prevent the escape of asbestos fibers into the air outside of the containment area. By ensuring that the air pressure inside the enclosure is less than outside, any air movement is directed inward, effectively containing potentially harmful asbestos particles.

This is crucial for the safety of both workers and the general public, as it minimizes the risk of airborne contamination. The use of negative pressure can incorporate filtration systems to further enhance safety by cleaning the air before it is released back into the environment.

Understanding how negative pressure works is essential for professionals involved in asbestos inspection and abatement, as it forms a core part of the safety protocols intended to manage the risks associated with asbestos exposure.
