In the Occupancy Hazard Classification system, which code corresponds to High Hazard Occupancy?

• A. 7
• B. 3
• C. 4
• D. 5

Answer: (C)

Understanding how the Occupancy Hazard Classification works helps you see why this code is used for High Hazard. The system uses a numeric scale to categorize how dangerous an occupancy is during live-fire evolutions, guiding safety planning and controls. High Hazard Occupancy is placed at the upper end of that scale, identified as the fourth category. That placement signals the IIC to implement the most protective measures—extra personnel, tighter supervision, stricter entry/exit controls, thorough pre-fire risk assessment, and a readiness to halt the evolution if conditions worsen. The lower numbers on the scale correspond to less hazardous occupancies, so they do not indicate High Hazard.
