Which option is NOT a typical use of a thermal imaging camera on the fire ground?

• A. Determining exact building construction materials.
• B. Locating hotspots concealed by smoke.
• C. Finding victims behind walls or obstacles.
• D. Guiding search and rescue operations.

Answer: (A)

Thermal imaging cameras on the fire ground are used to visualize heat differences, letting firefighters see through smoke and darkness to identify hot spots, locate heat sources behind walls or obstacles, and guide search and rescue operations. They help you prioritize suppression and navigate safely by revealing where the fire is hottest and where victims or hot objects may be hidden.

They do not provide reliable information about exact building construction materials. A TI image can show heat patterns that might suggest different conditions inside walls, but it cannot definitively determine whether a wall is wood, masonry, concrete, or steel. Identifying construction materials relies on visual inspection, pre-incident plans, or other specialized methods, not thermal imagery.
