What is one primary function of a thermal imaging camera on the fireground?

• A. To locate hidden fires, identify hot spots, and help locate occupants or unsafe structural conditions.
• B. To measure exterior weather conditions.
• C. To record video for after-action review only.
• D. To replace the need for water with cameras.

Answer: (D)

Thermal imaging cameras give you the ability to see heat, which lets you see through smoke and darkness. Their main function on the fireground is to locate hidden fires, identify hot spots that could rekindle, and help find occupants or unsafe structural conditions. This heat visibility guides where to direct water, where to ventilate, and where to search, making operations safer and more efficient. They’re not used to measure weather, aren’t simply for recording video, and don’t replace the need for water or other firefighting tactics; they provide real-time heat information that shapes tactical decisions.
