The purpose of 'size-up' in firefighting is fundamentally about gathering information regarding the incident environment. This critical assessment enables firefighters to understand various elements such as the nature and source of the fire, building construction, potential hazards, and the presence of occupants. By effectively performing a size-up, firefighters can make informed decisions on the appropriate tactics to employ, ensuring both their safety and the safety of those affected. This process typically includes visual observations, reconnaissance, and information gathering from witnesses or bystanders to form a comprehensive situational awareness before taking action.

Assessing firefighter performance, evaluating equipment readiness, and conducting public safety assessments are important aspects of firefighting but are distinct from the size-up process itself. The size-up primarily focuses on understanding the incident and its challenges, allowing other processes to be addressed afterward as part of a coordinated response.
