Which of the following is NOT listed as a high-yield ARFF rescue/entry tool?

• A. Circular saw
• B. PPV fan
• C. De-arming tool
• D. Thermal imaging camera

Answer: (D)

In ARFF rescue work, tools are judged by how directly they enable rapid access and rescue, not just by helping observe or assess. A circular saw is a prime example: it lets you quickly breach through aircraft skin or structural panels to reach occupants or critical compartments, which is essential when every second counts. A positive-pressure ventilation (PPV) fan directly improves the rescue environment by pushing smoke and heat away from entry points, creating a safer, tenable area for both victims and responders and speeding up search and egress. A de-arming tool serves to defeat safety interlocks or door arming mechanisms so you can quickly open emergency doors or access points, removing obstacles to entry and rescue. By contrast, a thermal imaging camera, while incredibly valuable for locating heat sources, fires, or hidden victims, is a diagnostic tool. It aids situational awareness rather than directly enabling entry or rescue actions, so it isn’t considered a high-yield rescue/entry tool.
