Abstract: A device (10) is disclosed. It has a gas impervious barrier (12) configured to be located between an opening of a container (16) and a door (18) arranged to close the opening. There is a passageway (14) through the barrier, the passageway (14) providing a pathway between the interior and exterior of the container (16) for a gas.

Abstract: A method for fumigating an enclosed space (12) comprises the steps of containing a gaseous fumigant at a discrete location within the enclosed space (12) so as to displace a volume of gas from the enclosed space, and releasing the contained fumigant from the discrete location and into the enclosed space. The method can employ an apparatus (10) that comprises a flexible enclosure (12) that is inflatable and deflatable with a gas between an expanded configuration and a collapsed configuration. The enclosure (12) can be positioned within the enclosed space (12) prior to fumigant introduction. The apparatus (10) can also comprise an inlet (16) arranged at the enclosure to receive gaseous fumigant therethrough for inflation of the enclosure (12), as well as an outlet (20) and a valve (24) arranged at the enclosure (12).

Abstract: The present application includes a module including a panel positionable in or at an opening of an enclosed space to define a fumigation chamber. A fumigation inlet can be arranged in the panel to allow a flow of a fumigant directly into the fumigation chamger. Mixing fans are provided that can circulate gases within the fumigation chamber. A system control box can be linked to the fumigant delivery orifice and valve system to control the flow of gas into the fumigation chamber. The panel can be secure against the passage of fumigant by a seal located around a perimeter of the panel.

Abstract: A method of removing a residual gas from inside a conventional shipping container is disclosed. The method first involves the step of accessing the container by opening a door of the container and fitting a panel to the open door space. Next the method involves extracting at least some of the residual gas present in the container via an outlet valve located at the panel using an external suction pump. Finally the method involves providing a flow of a flushing gas into the container via an inlet valve located at the panel to flush residual gas from the container. The total pressure of gases in the container can be monitored and controlled by adjusting the flow of gases in the inlet and outlet holes or valves.

Abstract: A fumigation apparatus including a conventional shipping container (10), a partition (14) dividing the container into a fumigation chamber and a control room (12), means (24) arranged to supply gas into the fumigation chamber (16), control means (26) located in the control room arranged to control the flow of gas into the fumigation chamber (16) and extraction means (36, 38, 40, 42, 44) arranged to remove gas from the fumigation chamber as controlled from the system control box (26).
