Who activates the Emergency Operations Center (EOC)?

• A. Installation Commander
• B. Governor
• C. DHS Secretary
• D. Incident Commander

Answer: (A)

Activation authority for the EOC focuses on who has the overarching responsibility to marshal resources and coordinate across units during a significant event. On a military installation, that responsibility sits with the Installation Commander, who owns base-wide safety, security, and continuity. When an incident requires coordinated effort across multiple base departments and external partners, the Installation Commander triggers EOC activation to bring together security, public works, medical, public affairs, and others, establish the situation picture, and allocate resources. The EOC then serves as the central hub for situational awareness and unified decision-making, ensuring actions stay coordinated and consistent.

The Incident Commander leads on-scene operations and can request EOC support, but the official activation for the installation’s EOC comes from the Installation Commander. The Governor would take action at the state level for incidents extending beyond a single installation, and the DHS Secretary would be involved for national-scale emergencies.
