What does the term 'size up' refer to in incident response?

• A. A mental evaluation of incident factors that determines the course of action necessary to achieve a desired goal
• B. A weather forecast for the incident
• C. A checklist of equipment required
• D. A physical measurement of building dimensions

Answer: (A)

Size up in incident response is the mental assessment of the situation that guides what you do next. It’s about quickly gathering facts and weighing factors—what is happening, where it’s happening, who’s at risk, what hazards exist, what resources are available, and what time constraints matter. This informed judgment helps determine the best course of action to achieve the response goals, typically prioritizing life safety first, then incident stabilization, followed by property conservation. It’s an active, ongoing process as the scene evolves, not a weather forecast, not a checklist of gear, and not a measurement of building dimensions. For example, at the scene of a structure fire, size up involves noting fire location, occupancy, smoke and heat conditions, potential for rapid spread, entry and escape routes, electrical or other hazards, water supply status, and nearby resources. Based on that assessment, you decide whether to attack, to retreat, to request more units, or to set up ventilation and rescue operations.
