What is a TIC scan priority?

• A. Behind
• B. Ceiling
• C. Floor
• D. Walls/Center of room

Answer: (B)

When using a thermal imaging camera in a fire scene, the priority is to scan the ceiling first. Heat and hot gases rise, so the ceiling often shows the earliest and strongest thermal signatures. A quick ceiling sweep helps you pinpoint the seat of the fire, detect hidden fires in concealed spaces above the ceiling, and spot potential flashover indicators. This top-down view also aids in planning ventilation and routes of travel, since you can see where the hottest air is accumulating and where danger zones may form overhead.

Scanning behind or to the floor isn’t as informing at the outset because those areas are less likely to reveal the active fire’s location or worst-affected hotspots early on. Walls and the center of the room are important for understanding fire spread and locating visible flames, but the ceiling provides the most immediate insight into where the fire is and how it’s behaving, making it the best initial focus.
