Like other decontamination methods, CD gas decontamination is a multi-step process. The 4 steps of the CD gas process are pre-condition, condition, injection and exposure, and aeration. We speak of a parametric release as the process goes to the next step only after achieving the setpoints of previous step, thus assuring the fulfilment of the pre-established protocol. This make the decontamination method very flexible as to differences in volume or loads.
Raising of relative humidity (RH) levels to between 60-75%.
Hold time once relative humidity set point has been reached.
Generation and concentration monitoring of chlorine dioxide gas.
Removal of chlorine dioxide gas from chamber through HVAC or actif carbon scrubber.
