What type of signal is NOT considered a pyrotechnic signal?

Reflective tape is not classified as a pyrotechnic signal because it does not utilize fire or explosive materials to produce a visual signal. Pyrotechnic signals are designed to create visible and/or audible cues in emergency situations, typically involving the combustion of chemicals, which produces bright flames or loud noises to alert others. Flares and flame signals both fall under the category of pyrotechnics as they rely on burning substances to generate light or heat. Smoke signals, while not pyrotechnics in the same sense of producing light or loud sounds, can still involve fire in their creation. Reflective tape, on the other hand, is a passive signaling device that relies on light reflection rather than combustion, making it distinct from pyrotechnic signals.
