A factor in deciding to preplan a structure or area is

• A. Buildings with most fire alarms.
• B. Only buildings over five stories in height.
• C. Buildings with the most fire violations.
• D. The type of life hazards expected.

Answer: (D)

Preplanning a structure or area is driven by life safety considerations—the kind of hazards occupants may face and how people inside might need to be rescued or evacuated. The type of life hazards expected tells you where to focus your planning: who will be inside, how many people, whether there are vulnerable or dependent occupants, and what rescue or evacuation challenges could arise. For example, a hospital or school presents different life-safety needs than a warehouse, so the preplan focuses on appropriate entry points, stairwells, egress routes, and search and rescue priorities tailored to those conditions. While factors like the number of fire alarms, the building’s height, or observed violations can influence risk, they don’t determine the need for preplanning as directly as the occupants and their potential hazards do.
