In this situation the priority is safety for everyone on board. After a CBRN incident, clearance to fly hinges on proper decontamination and medical evaluation, plus reassurance that there’s no residual contamination or delayed symptoms developing. A short waiting period is used to let any off-gassing settle and to catch any evolving symptoms in a controlled setting before air transport. This minimum interval is chosen to balance the need to evacuate promptly with the need to avoid introducing contaminated or at-risk individuals into the aircraft. Longer delays would unnecessarily impede evacuation, while going too soon could risk onboard contamination or medical deterioration. So, the recommended approach is to wait a minimum safe period after decontamination and clearance, before proceeding with flight.
