D)a device that can be repurposed by technologically-sophisticated arsonists to start fires.

Question

Quizplus · Accepted Answer

Catalytic combustion detectors are commonly used by arson investigators for detecting the presence of flammable vapors. They work by oxidizing the vapors and producing a detectable signal. They are not used for detecting explosive bombs or for approaching and analyzing unknown explosive devices. It would not be practical for arsonists to repurpose catalytic combustion detectors to start fires as these detectors require an external ignition source to function.
