Primary search should be conducted in all involved and exposed occupancies that can be entered. Which option best reflects this guidance?

• A. All involved and exposed occupancies that can be entered
• B. Only the primary structure
• C. Only uninhabitable areas
• D. Exterior exposures only

Answer: (A)

The key idea is that primary search aims to locate any occupants in all areas that could reasonably contain people, including spaces that are involved in the fire and any connected or exposed structures that firefighters can legally and safely enter. Because occupants may be inside not only the main building but also in adjacent or exposed spaces, you search every area that can be entered to maximize chances of rescue while fire conditions permit.

Searching only the primary structure would leave potential occupants in other occupied spaces unseen. Focusing on uninhabitable areas or exterior exposures only ignores interior rooms and connected spaces where people could be trapped. By including all involved and exposed occupancies that can be entered, you ensure a comprehensive, timely initial search that aligns with life-safety priorities.
