What term describes evaluating the entire incident to determine needed resources and their availability?

• A. Stabilization
• B. Size-up
• C. Assessment
• D. Triage

Answer: (B)

Size-up is the process of taking in the entire scene—from fire conditions and hazards to occupancy, location, life-safety issues, and potential for spread—and using that information to decide what resources are required and whether they are available. It starts as soon as you arrive and continues as conditions evolve, forming the basis for the incident action plan and for coordinating resources, including mutual aid. This concept is broader than simply assessing individual elements or chasing immediate tasks. Triage focuses on sorting victims, stabilization aims at controlling hazards, and a general assessment evaluates conditions; size-up specifically centers on determining needs and the availability of those resources to meet the incident’s demands.
