When does the Size Up process begin in fire management?

The Size Up process in fire management is a critical assessment that begins during preplanning. This phase involves gathering necessary information about the structures, potential hazards, access points, and resources that are essential in understanding the fire environment before any incident occurs. By conducting thorough preplanning, firefighters can anticipate various scenarios, identify risks, and develop strategies tailored to particular buildings or areas, enhancing their effectiveness and safety during actual emergencies.

While some may think the Size Up process starts upon arrival at the scene, it is important to note that foundational knowledge and preparation during preplanning play a significant role in how effectively firefighters assess the situation once they arrive. Proper preplanning allows for a more efficient and informed Size Up, as responders have already considered important factors that will impact their response. This proactive approach ensures they are equipped with the information necessary to make quick and informed decisions on scene.
