What should be done after the incident commander completes the initial size up?

After the incident commander completes the initial size-up, the next critical step is to develop an incident action plan. This plan is essential for effectively managing the incident, as it outlines the strategic objectives, tactical actions, and resource allocation needed to mitigate the situation.

The size-up process involves assessing the incident's scope, identifying hazards, evaluating the resources available, and determining the needs for effective operational response. With this comprehensive information at hand, the incident commander can craft a coherent action plan that ensures all responders are coordinated and focused on achieving specific goals, such as fire suppression, rescue operations, or public safety measures.

The action plan serves as a guiding document that not only communicates the intended strategies to all personnel on scene but also helps in prioritizing tasks, managing resources, and establishing safety protocols. This methodical approach is vital in ensuring an organized response and ultimately contributes to a successful resolution of the incident.

Other options, while potentially relevant in different contexts, do not follow directly from the size-up process. For instance, evacuation procedures may need to be implemented depending on the situation, but they are based on the information gathered during the size-up and the decisions made in the action plan. Notifying administrative authorities typically occurs later, primarily to inform them of the situation
