In addition to marked coordinates and traffic patterns, what else should a grid map include?

A grid map should include control zones because these areas outline specific regions that fire department personnel must be aware of in the event of an emergency. Control zones are critical in managing the scene of an incident, ensuring safe operation procedures, and effectively coordinating response efforts. These zones can represent areas of high risk, hot zones where immediate hazards exist, areas where personnel can safely operate, or even staging areas for support units.

Control zones provide clear guidance on where responders should and should not go, which is essential during an unexpected situation like an aircraft fire or hazardous material spill at an airport. Including control zones on a grid map enhances situational awareness and enables efficient command structure and communication, ultimately increasing safety and effectiveness during a firefighting operation.

While the other options also contribute to situational awareness and emergency planning, they do not address the necessity of defining clear operational boundaries that control zones provide.
