A method for fumigation perishables within an existing refrigerated cargo container that does not require the refrigerated cargo container to be tented. The method uses the inherent characteristics of the cargo container to form the fumigation chamber environment. The method insures that the cargo container is fit for fumigation purposes, more specifically, that the refrigerated cargo container does not allow the escape of fumigant beyond the reasonable level allowed by the agency monitoring the fumigation process.

1. A method for fumigating perishables within a refrigerated cargo container, wherein said refrigerated container comprises of a pair of front and a pair of rear drain holes, an air exchanger, a pair of doors located at the rear of said container, and a refrigeration system, said method for fumigation comprising:checking said container for any damaged areas; if damaged areas found, then sealing said damaged areas with a means for sealing said damaged areas; placing at least one fan within said container; clearing the pair of rear drain holes of said container; inserting through one of the rear drain holes a gas introduction hose, then connecting said gas introduction hose to one of the fans earlier placed within said container or to the fan earlier placed in said container; inserting through the other rear drain hole a plurality of reading lines for measuring the dispersion of fumigant within said container and an electrical line for powering said fans or fan; positioning said reading lines within said container; sealing the rear drain holes with a means for sealing the rear drain holes; plugging the front drain holes with a means for plugging holes; closing the air exchanger; checking the temperature of the perishable to be fumigated; determining the dosage of fumigant to be used in the fumigation process; closing and securing the doors of the refrigerated cargo container; releasing the fumigant required to fumigate through the gas introduction hose into said container; checking with a gas or a halide detector the outside of said container for any fumigant leaks; if leaks are discovered, then sealing the areas of said container found to have leaks with a means for sealing the areas found to have leaks; re-checking with the gas or the halide detector the areas of the container that were discovered to have leaks; if leaks are controlled, then conducting the fumigation process; and lastly, aerating the perishable fumigated for the required amount of time needed to clear the container of the fumigant used in the fumigation process.
