What are the two types of beacons used in distress signaling?

The correct choice identifies the two types of beacons used in distress signaling as square green and triangle red. In maritime operations, specific shapes and colors are utilized to convey different meanings, especially in emergency situations.

The square green beacon serves as an indication of a man overboard or other distress situations where visibility of the signal is crucial for nearby vessels to respond effectively. It provides a clear visual representation that something urgent is occurring.

The triangle red beacon, on the other hand, is universally recognized as a symbol of danger or distress. This color and shape combination is designed to attract attention quickly from other vessels or aircraft that may be nearby, signaling that assistance is needed.

These visual signals are part of an established communication protocol in maritime distress signaling, ensuring clarity and immediate recognition in time-sensitive scenarios. Understanding these designations can significantly enhance response times and operational effectiveness during emergencies at sea.
