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).

Abstract: A portal apparatus in the form of an arch-shaped pipe fitting (10) for use with a fumigation chamber that in part incorporates a flexible canopy. The pipe fitting (10) can be seated on the ground (12) so as to be positioned between the canopy and the ground (12). A sealing surface (22) on the pipe fitting (10) is contactable with the flexible canopy so as to provide a gas-tight seal. An assembly for directing the flow of gas in general, the assembly being operable in various configurations, and comprising first and second gas inlets and outlets respectively. An assembly for operatively coupling gas extraction, treatment and recirculation apparatus, and comprising first and second gas inlets and outlets respectively that can be selectively coupled in first and second configurations.

Abstract: As shown in FIG. 1 there is one embodiment of a fumigation apparatus in the form of a module (8) including a panel (10) which can be positioned in or at an opening of an enclosed space in use to define a fumigation chamber. Fumigant inlet means in the form of an orifice (12) are arranged in the panel (10) to allow a flow of a fumigant directly into the fumigation chamber. A nominal number of mixing fans, in this case two fans (16) and (18), thoroughly circulate gases within the fumigation chamber when operating. The module (8) includes a system control box (14) linked to the fumigant delivery orifice (12) and valve system which functions to control the flow of toxic gas into the fumigation chamber. The panel (10), when positioned in use, is secure against the passage of fumigant and gases by means of an inflatable rubber seal (22) which is located around a lip edge perimeter of the panel (10).
