What distinguishes immediate need evacuations from planned need evacuations?

• A. Immediate need evacuations will not have planned decision points already identified to trigger an evacuation order
• B. Immediate need evacuations require shelter in place
• C. Immediate need evacuations involve a full evacuation
• D. Immediate need evacuations require shelter in place and evacuation routes

Answer: (C)

Immediate need evacuations are driven by an imminent threat that requires rapid, comprehensive removal of people from the affected area. Because the danger is immediate, the response is a full evacuation of the zone rather than sheltering in place or staging partial moves. Planned need evacuations, in contrast, are preplanned and can be conducted in stages, with shelter-in-place options or partial evacuations as dictated by the situation and logistics, guided by identified decision points.

So the key distinction is the scope and urgency: immediate need evacuations involve a full evacuation, while planned need evacuations are managed and staged rather than a rapid, complete outflow.
