What is the primary function of flares in maritime survival situations?

The primary function of flares in maritime survival situations is to provide a visual distress signal to rescuers. Flares are designed to be highly visible and can be seen from a significant distance, even in challenging weather conditions or at night. When a mariner is in distress, signaling with flares is a crucial method of alerting nearby vessels or rescue services to their situation. This helps facilitate a quicker response, increasing the chances of rescue.

The use of flares is part of standard maritime safety equipment and training, underscoring their importance in emergency protocols. Their distinctive color and brightness make them effective for attracting attention, thereby serving an essential role in search and rescue operations.
