During size-up, which concept evaluates the viability and survivability of potential fire victims under current structural conditions?

• A. Size-up
• B. Survivability profiling
• C. Risk management
• D. Triage

Answer: (B)

Survivability profiling is the element of size-up that asks: can potential fire victims realistically survive under the current structural and fire conditions? It involves quickly assessing factors like how the fire is behaving, the location and accessibility of occupants, the integrity of floors and walls, ventilation paths, and the time available before conditions worsen or a collapse becomes a risk. This assessment directly guides rescue decisions—where to search, what entry methods to use, and whether conditions permit a rapid, aggressive rescue or require a defensive stance.

Other concepts describe different parts of the incident response. Size-up is the overall ongoing assessment, of which survivability profiling is a focused part. Risk management deals with identifying hazards and implementing controls to reduce risk, not specifically judging victim viability in real-time. Triage relates to prioritizing medical treatment once victims are located, not evaluating their likelihood of survival under current structural conditions.
