What factors must an ongoing size-up consider during an incident?

During an incident, an ongoing size-up is crucial for adapting and refining the response strategy. The effectiveness of the initial plan encompasses several elements that can change as the situation evolves. Evaluating the initial plan allows responders to determine whether the tactics being implemented are achieving the desired outcomes or if adjustments are necessary based on the dynamic conditions of the incident.

Assessing the effectiveness of the plan involves monitoring the fire behavior, which includes its location and size, as well as other external factors like weather conditions and personnel availability. This comprehensive approach enables firefighters to make informed decisions and maintain operational safety while aiming to mitigate the incident effectively.

Other factors, while important, do not capture the whole essence of ongoing size-up in the same way that evaluating the effectiveness of the plan does. For instance, knowing the fire's location and size is certainly vital, but it is a component of the overall assessment rather than the core focus of an ongoing evaluation. Weather conditions, while also significant, are just one of many elements in determining how well the strategy is performing. Personnel availability is crucial, but solely focusing on it doesn't fully encompass the need for ongoing revisions to the operational approach based on what is happening on the ground.
