When is it appropriate to use flares?

Using flares is specifically intended for distress situations to signal for help. In emergencies, when a boater is in need of assistance, flares serve as a visible alert to other vessels or rescue services that someone requires urgent help. They are designed to be highly visible and can be seen from great distances, making them an effective way to communicate distress on the water.

The other options do not align with the intended purpose of flares. Signaling non-distress situations, for example, would misuse this important safety tool, as flares are reserved specifically for emergencies. During celebrations or events, other more appropriate signaling devices or methods should be used, as flares carry a serious connotation and can cause concern for safety. Additionally, flares are effective at any time, day or night, as they produce a bright light that can be seen in darkness; therefore, limiting their use to daylight hours would not take full advantage of their life-saving capabilities.
