The Warm Zone is defined as...

• A. Medical triage and decontamination done here
• B. No entry restricted
• C. General public assembly area
• D. Command post only

Answer: (A)

In incident response, the area layout uses zones to prevent spread of contamination and to manage safety. The Warm Zone sits between the heavily contaminated Hot Zone and the clean Cold Zone. Its purpose is to provide a buffer where contaminated individuals can be decontaminated and where initial medical triage and care can occur before people move into the clean area.

That’s why the best answer is that medical triage and decontamination are done here. It captures both the treatment and the removal of contaminants in a controlled, transitional space, which is the core function of the Warm Zone. The other notions don’t fit because the Warm Zone isn’t simply about entry restrictions without context, nor is it the general public assembly area or the command post; those roles belong to other parts of the operational area.
