Definitive triage and treatment take place in the cold (clean) zone after casualties have passed through decontamination, because the hot zone is the contaminated area where only those in appropriate specialist protection should operate. Setting up in the hot zone (A) or unprotected in the warm zone (D) exposes responders and casualties to ongoing contamination. Casualties move hot, then warm (decontamination), then cold.
