What is the significance of three fires in a row as a distress signal?

Three fires in a row serve as a universally recognized signal indicating an urgent need for assistance. This signal is part of established maritime distress signals, intended to be understood by vessels and personnel across different regions and languages. The simplicity and clarity of this signal help ensure that anyone observing it can promptly convey the urgency of the situation to others and take necessary action.

While other signals may indicate different situations, such as celebrations or drills, three fires in a row specifically and solely communicates that immediate help is required. This characteristic makes it vital for mariners and rescuers to recognize it as a serious distress signal, prompting them to respond swiftly and effectively to prevent potential loss of life or property.
