What is the second major consideration during size-up of a building?

• A. The exterior construction
• B. The time of day
• C. Its use and occupancy
• D. The weather conditions

Answer: (C)

Understanding size-up starts with quickly identifying what you’re dealing with and what risks exist for anyone inside or around the building. The second major factor to determine is how the building is used and who occupies it. This matters because occupancy tells you how many people could be inside, what kinds of activities are happening, and what hazards those activities bring. For example, spaces with large numbers of people or specialized operations (like schools, theaters, hospitals, or laboratories) create significant life-safety challenges and shape how you approach rescue, evacuation, and fire control. It also helps you anticipate what kinds of contents or materials are likely to be present, which affects fire behavior, exposure risk, and the resources you’ll need. In short, knowing the use and occupancy helps you gauge the scale of potential life hazards and tailor your tactics accordingly.
