What is the most essential action a company officer should perform at the start of an operation?

At the start of an operation, sizing up the situation is critical for a company officer. This process involves gathering and analyzing information about the scene, including the presence of fire, potential hazards, building structure, and the conditions affecting both the fire and any occupants. By performing a thorough size-up, the officer can make informed decisions regarding resource allocation, tactical approaches, and overall incident management.

The size-up helps establish a clear understanding of the operational environment, which is essential for effective communication with the team and coordinating the response efforts. This assessment also allows the officer to identify priorities for safety, determining whether to initiate an attack, call for backup, or take other actions based on the evolving situation. Ultimately, the size-up lays the groundwork for a successful operation by ensuring that all subsequent actions are based on an accurate assessment of the incident.
