In mass casualty incident response, which entity typically leads on-scene operations and what is the role of hospitals?

• A. Local fire department leads; hospitals fund the response.
• B. Local EMS agency and coordinating agencies lead on-scene; hospitals provide treatment capacity, surge management, and reporting; EMS routes patients and maintains communication.
• C. Federal agencies lead on-scene; hospitals provide transport only.
• D. Private security firms lead; hospitals store supplies.

Answer: (B)

In mass casualty incident response, on-scene leadership is provided by the local EMS agency working with coordinating local agencies under the Incident Command System. This team establishes command, conducts triage, ensures scene safety, and allocates resources and responders to tasks across the incident.

Hospitals play a critical support role by providing treatment capacity and managing surge—expanding bed availability, prioritizing care, and coordinating with EMS on patient destinations. They also report patient information and status to the incident command and maintain communication to synchronize hospital and field operations, including continued patient routing as the situation evolves.

Other options don’t fit because the on-scene lead in most MCIs is not federal agencies or private security firms, and hospitals are not limited to transport duties; their primary function is to treat the injured and manage hospital-based surge with EMS coordination.
