Which statement about incident command is true?

The statement that incident command must establish a command post on-site is true because having a command post directly at the scene of an incident allows for effective coordination and immediate decision-making. Being on-site helps to ensure that key personnel have real-time access to firsthand information about the situation, resources, and needs of the emergency response. This proximity also facilitates better communication among various teams and enhances situational awareness, which is crucial during any incident.

Furthermore, the on-site command post serves as the central location for command staff to manage operations, allocate resources, and provide support to field personnel, all of which are essential for an effective response. This location is where strategies are developed, objectives are set, and ongoing assessments of the situation are made, ensuring a unified and efficient response to the incident at hand.
