To fumigate containers, we’ll use the most suitable method for your particular circumstances, but this will generally involve either pressure decay or tarped fumigation.
The pressure decay technique involves testing the container to see if it can maintain a certain pressure value for a timed period and if so, then it’s deemed ‘gas tight’. It can then be fumigated without the need for a tarp.
Tarped fumigation, on the other hand, requires the use of a tarp for containers that haven’t passed the pressure decay test or where this simply hasn’t been carried out. Our team will cover the container with a special gas-proof tarp, using sand to seal this off and prevent the gas from escaping.
