Similar to all other decontamination methods, CD gas decontamination is a multi-step process. The 5 steps of the CD gas process are pre-condition, condition, injection, exposure, and aeration.
Raising of relative humidity (RH) levels to between 60-75%.
Hold time once relative humidity set point has been reached.
Generation and delivery of chlorine dioxide gas.
Hold time once gas concentration set point has been reached.
Removal of chlorine dioxide gas from chamber.
The Exposure step is controlled through an “area under the curve” accrual of gas concentration until a target dosage has been met.
