Why is it important to notify dispatch during incident termination?

Notifying dispatch during incident termination is crucial as it informs them that the responding units are back in service and available for the next call. This communication is vital for maintaining an accurate understanding of resource availability. It allows the incident scene to be properly documented, enabling dispatch to manage current and future incidents effectively. This communication ensures that emergency response teams can be deployed quickly and efficiently as new situations arise, ensuring public safety and operational readiness.

The other options focus on actions that, while potentially important in their own right, do not directly pertain to the immediate necessity of informing dispatch about a unit's readiness status post-incident.
