Abstract:
A method for killing organisms and removing of toxic substances from an enclosure, which comprises the steps of:preparing an enclosure having an interior and an exterior for exposure to a high temperature gas by removing or protecting all heat sensitive items;positioning a plurality of temperature indicating probes at predetermined locations in said enclosure;providing at least one ingress duct communicating with said interior of said enclosure and at least one egress duct communicating between said interior and said exterior of said enclosure;directing said heated gas into said enclosure through said at least one ingress duct for a time sufficient to raise the temperature of said enclosure to said lethal temperature;heating an environmentally acceptable gas to a temperature lethal to predetermined organisms;monitoring the temperature from said probes;recording said temperatures from said probes in real time;establishing at least a slight positive pressure within said enclosure;venting said heated gas from said enclosure; andfiltering air passing through said egress duct through a filter to remove remains of said organisms carried by said air.
