The invention relates to a chamber (10) for use in a fumigation method to produce a fumigant gas mixture and supply it to a circulatory loop gas flow system gas, the chamber (10) adapted to receive fumigant gas generation means and wherein the chamber (10) includes: an inlet port (12) controlled by an inlet valve (14), and outlet port (16) controlled by an outlet valve (18), A flushing gas inlet controlled by a flushing gas inlet valve (22) for connection to a source of inert gas (24), a vent valve (26), the chamber (10) having access means (44) openable for access to its interior from a position outside of the fumigation space, the chamber (10) forming part of the loop gas flow system when connected to ends of a gas duct when the inlet (14) and outlet (18) valves are open. The invention further relates to a method of fumigating a bulk commodity in an enclosed fumigation space wherein the fumigant gas mixture is generated in the chamber (10) as well as to use of the chamber (10) in such a fumigation method. <IMAGE> |
