Correct answer: APrevent secondary contamination and direct them through decontamination before transport where clinically possible

Contaminated casualties can contaminate responders, ambulances and hospitals. Decontamination and scene control should occur before transport when clinically possible, with lifesaving care adapted to PPE and hazard constraints. Walking ability does not remove contamination risk. The pearl is that uncontrolled evacuation can spread an incident to the receiving hospital.
