Container treatment

A method of decontaminating a freight container comprising the steps of:

• a) heating a support base;
• b) placing a freight container on a support base wherein the support base provides a pressure accumulating conduit, the pressure accumulating conduit including a series of vents, the support base also provides for an air gap beneath the container;
• c) using an enclosure to substantially enclose the container on the support base;
• wherein the enclosure comprises a flexible roof and at least one flexible side;
• and
• d) applying heat at a temperature between 80° C. and 150° C. and a rate of between 250 m3/min and 500 m3/min to an opening in the pressure accumulating conduit so that hot air moves through the pressure accumulating conduit and through the vents to distribute the air across the support base to the edges of the support base and upwards around the sides and a roof of the container, to kill or substantially weaken undesired life forms on or immediately adjacent to the exterior of the container;
• e) applying heat to openings in the enclosure to circulate a supplementary flow of hot air through the enclosure;
• and
• f) providing an air supply pipe arranged to direct a flow of hot air into open doors of the container and providing hot air to the air supply pipe from the pressure accumulating conduit so as to decontaminate the inside of the chamber.
