Historical Background
The SOS signal was first introduced in 1905 as an international standard for maritime distress. Before that time, ships would use a variety of different signals, including flags, flares, and horns, to request assistance.

However, there was no universal signal that could be easily recognized and understood by all seafarers. The need for a standard distress signal became apparent after the tragic sinking of the Titanic in 1912. Although the Titanic used a wireless telegraph to call for help, the signal was not recognized by all stations on the receiving end. As a result, a number of ships that could have potentially come to the Titanic’s aid were unaware of the distress call.
To address this issue, the International Radiotelegraph Convention of 1906 established the SOS signal as the standard distress signal for maritime communication. The signal consists of three short, three long, and three short signals, with no spaces in between: “· · · – – – · · ·”. This pattern is easy to remember and can be transmitted quickly and clearly using Morse code.
Uses and Applications
Since its introduction, the SOS signal has been used not just in maritime communication, but in many forms of communication. It is commonly used in aviation, outdoor activities, and emergency situations. For example, hikers who become lost in the wilderness can use an SOS signal to alert search and rescue teams to their location. Similarly, pilots who experience a malfunction in their aircraft can use an SOS signal to request emergency assistance.
In addition to its traditional use in Morse code, the SOS signal is also used in other forms of communication. For example, many mobile phones have an SOS feature that allows users to send an emergency message to a designated contact. This feature can be activated quickly and discreetly in situations where it may not be safe to make a phone call.
Conclusion
The SOS signal is a universal symbol of distress that has been used for over a century. Its introduction as an international standard for maritime distress has made it possible for seafarers and other travelers to communicate their need for help in a clear and recognizable way. Today, the SOS signal continues to be an important tool for emergency communication, used in a variety of settings to request assistance and alert others to potentially life-threatening situations.
