What characteristic must an airlock possess according to New York regulations?

An airlock is designed to serve as a barrier that helps control contamination and protect against the spread of asbestos fibers. According to New York regulations, one of the primary characteristics an airlock must possess is a minimum length. This requirement is in place to ensure that there is adequate space for individuals to properly decontaminate themselves and their equipment before entering a clean area. The minimum length of the airlock helps to effectively contain any potential asbestos particles and reduces the risk of their dispersion into uncontaminated zones.

While being fully enclosed, having multiple entrances, or being ventilated can also play roles in the overall effectiveness and safety of an airlock, the specification of minimum length is particularly critical from a regulatory perspective. It directly addresses the need for effective decontamination processes which are vital in asbestos handling.
