Which of the following is NOT listed as an extension detection method?

Explanation:
Extension detection methods rely on the firefighter’s direct senses being extended into a difficult environment—what you can perceive with your eyes, hands, and ears. Sight, touch, and sound are the natural ways you assess ongoing conditions, locate victims, and sense movement behind obstructions without relying on specialized equipment. Infrared imaging, while extremely useful, is a tool that provides information through a device (thermal camera) and interpretation of heat signatures. It isn’t a direct extension of a human sense, which is why it isn’t listed as an extension detection method.
