The specific size up for an incident begins with which event?

The specific size-up for an incident begins with dispatch. This initial step sets the context for the incident response by providing critical information such as the nature of the call, location, and any available preliminary details. These elements guide the responding units in their preparations and strategies before they even arrive on the scene.

By understanding the dispatch information, fire officers can assess the potential risks and needs associated with the incident, anticipate the resources required, and formulate a response plan that aligns with the situation described. This foundational step is essential, as getting an accurate picture of an incident allows for a more effective operational strategy once on-site.

Arrival on the scene, assessment of resources, and the initial report all follow the dispatch phase and rely on the information it provides to inform further actions. Therefore, the size-up process is fundamentally initiated at the moment of dispatch, highlighting its importance in incident management.
