When does a size-up begin?

• A. As soon as dispatch radios the call out
• B. After arrival and immediate assessment
• C. After written report
• D. Only after stage two of ICS

Answer: (A)

Size-up begins as soon as you have information about the call, using what the dispatcher provides about location, type of incident, hazards, and potential victims. This early assessment is ongoing and guides your initial actions and resource needs well before you arrive on scene. Waiting to start size-up until you arrive, after a written report, or only during a specific ICS stage would delay critical safety decisions and initial planning. Starting the size-up at dispatch time helps you anticipate hazards, determine needed resources, and set the right priorities from the outset.
