During size up local subject matter experts can include?

• A. Nurses
• B. Librarians
• C. Accountants
• D. Structural engineers

Answer: (D)

Size-up relies on bringing in people who have knowledge directly affecting safety decisions in the moment. A structural engineer is the essential local expert for assessing building integrity, understanding how loads travel through the structure, how deterioration or damage changes that behavior, and what stabilization or shoring is needed. Their input helps determine if the structure is stable enough to support rescuers, where collapse hazards exist, and how to plan safe entry and search operations to prevent a progressive failure. The other roles listed aren’t focused on evaluating structural stability on a collapse scene, so they don’t contribute to the immediate risk assessment in the same way.
