In the Incident Command System (ICS) used in public health disaster response, what are the primary responsibilities of the Incident Commander, Public Information Officer, and Liaison Officer?

• A. Public Information Officer handles media and public messaging; Liaison Officer coordinates with external agencies; Incident Commander oversees all operations
• B. Incident Commander oversees all operations; Public Information Officer handles media and public messaging; Liaison Officer coordinates with external agencies
• C. Liaison Officer manages internal staff and logistics; Incident Commander handles safety; Public Information Officer coordinates external agencies
• D. Safety Officer oversees all communications; Incident Commander handles operations; Public Information Officer handles procurement

Answer: (B)

In the Incident Command System, roles are separated to keep command, information, and external coordination clear and effective. The Incident Commander is responsible for overall management of incident objectives and operations, translating priorities into action and ensuring safety and accountability across the response. The Public Information Officer serves as the official spokesperson, handling media relations and public messaging to inform the community and manage public perception. The Liaison Officer acts as the primary contact with external agencies and organizations, facilitating communication, coordination, and resource sharing to ensure a unified response.

This combination aligns with how ICS structures leadership and communication. Other options mix up these responsibilities—such as assigning procurement or internal staff duties to the Public Information Officer, or placing safety or internal logistics under the wrong role—leading to confusion and fragmented response.
