Abstract: The disclosure relates to devices and methods for ventilating enclosed area such as shipping containers or structures erected to temporarily contain cargo items. A central element in such devices and methods is a ventilation stack assembly in which a vertically-oriented stack having an outlet is connected at its other end to a pipe leading to an inlet. A first housing having the dimensions (and preferably the fittings) of a standard shipping container is rigidly connected to the stack and pipes, and the assembly can be physically manipulated as if it were a standard shipping container. Gas (e.g., fumigant) provided to the pipe inlet passes through the pipe and into and through the stack, exiting at the outlet, which can be situated at an altitude whereat gas discharged therefrom is dispersed into the atmosphere at a location and concentration at which displeasure or hazard to humans can be reduced.
