Which item is known as a highway distress flare?

The correct response identifies a fusee as a highway distress flare. A fusee is a type of handheld signal used to indicate distress, typically during road emergencies. It is designed to burn brightly and can be seen from a significant distance, making it effective for alerting others to an emergency situation.

In the context of NFPA 1123 and fireworks safety, it's important to distinguish this from the other items listed. A comet, for instance, refers to a type of aerial firework that produces a long-lasting effect as it ascends and breaks apart in the sky, characterized by a trail of light. A lance is generally related to pyrotechnics used for cutting or signaling and does not serve the same purpose as a distress flare. Lastly, a match is a simple ignition source and does not provide any visual signal for emergencies.

Thus, the fusee is specifically designed for signaling distress on highways, making it the appropriate answer in this context. Understanding the unique functions and applications of these items helps reinforce safety measures and effective emergency response practices in fireworks displays and other related activities.
