During a disaster, what happens when an incident overwhelms local response capabilities?

• A. An incident that overwhelms local response capabilities; triggers mutual aid, triage, and expanded ICS structure.
• B. An incident resulting in widespread property damage but manageable within local resources.
• C. An incident that requires only law enforcement response.
• D. An incident that requires evacuation of a city block only.

Answer: (A)

When a disaster overwhelms local response capabilities, the response system scales up to bring in outside help and organize resources efficiently. Mutual aid arrangements are activated so neighboring jurisdictions can send personnel, equipment, and supplies to support the response. Triage is used to quickly assess and prioritize casualties when resources are limited, ensuring the most lives can be saved with the available assets. At the same time, the Incident Command System expands—more command staff, operations, planning, logistics, and finance sections come online, along with additional branches or divisions as needed, all guided by an Incident Action Plan. This combination of outside support, prioritization of care, and expanded command structure is what allows responders to manage a surge in demand and coordinate a larger, more complex response.
