What are categorized as non-pyrotechnic VDS?

• A. Smoke flares
• B. No lights or flames
• C. Non-combustible signals
• D. Only light signals

Answer: (C)

Non-pyrotechnic Visual Distress Signals (VDS) encompass a variety of signaling devices that do not rely on pyrotechnic materials, which means they do not produce a flame or explosion. Non-combustible signals are typically designed to provide visual alerts without generating heat or fire, making them a safer alternative in certain conditions, especially in areas where fire hazard is a concern. They can include items such as flags, lights, and other reflective materials that can attract attention when necessary. By understanding the nature of non-pyrotechnic signals, it becomes clear why the other options are not as fitting. Smoke flares, for instance, are specifically pyrotechnic due to their reliance on combustion to produce smoke for signaling. Choices that mention the absence of lights or flames would not properly categorize VDS since non-pyrotechnic options still rely on visual properties but do not include combustion, and light signals do not adequately cover the broader scope of non-pyrotechnic options. Thus, categorizing non-pyrotechnic VDS under non-combustible signals highlights their specific characteristics and safety benefits.
