What is SOS? Everything You Need to Know

SOS is a distress signal used to call for help, especially by ships in trouble. It is a signal of distress that everyone knows and is sent in Morse code as “……..”. Some people think that SOS means “Save Our Souls,” but it does not stand for anything. It is a signal that shows the need for help right away.

Important: The SOS signals should only be used in emergencies when immediate assistance is required. False alarms can divert resources from genuine emergencies and put lives at risk. It is crucial to understand and follow proper protocols and regulations when using SOS signals.

The Origin of SOS

The origin of the distress signal SOS can be traced back to the early 20th century. It was first introduced as a standardized international distress signal during the 1906 Radio Telegraph Conference in Berlin.

The purpose of adopting a universal distress signal was to ensure effective communication and coordination during maritime emergencies.

They chose the signal SOS, with its distinctive pattern of three short signals, three long signals, and three short signals again, because anyone could easily recognize and understand it regardless of language barriers. Since then, SOS has become synonymous with calling for help in emergency situations, particularly in maritime contexts.

How does SOS work

How does SOS work

The signal can be transmitted using various means, depending on the available resources and the situation.

Light signals

You can use a flashlight or any other light to make SOS signals in Morse code. Morse code is a way to use dots and dashes to spell words. SOS is three dots, three dashes, and three dots. You can flash the light to make the dots and dashes.

Sound signals

If you can’t see anyone or if sound can go farther, you can use sound to make SOS signals. You can yell or use a whistle to make three short sounds, three long sounds, and three short sounds again.

Radio signals

If you have a radio, you can use it to send SOS signals. You can press the microphone or make three short beeps, three long beeps, and three short beeps again.

Device signals

Some devices, like beacons or EPIRBs, have a button that says SOS. If you press it, the device will send a message to the people who can help you. The message will also tell them where you are.

Advantages of SOS

  • It can save your life or someone else’s life by getting help quickly and easily.
  • It can work in different ways, such as using light, sound, radio, or devices to send SOS signals.
  • Anyone can know and understand SOS, no matter what language they speak.
  • It can be used in various situations, such as on a ship, in a plane, outside, or on a phone.
  • It can give you peace of mind and comfort, knowing that you have a way to call for help if you need it.

The Morse Code Connection

SOS as a Distress Signal

Contrary to popular belief, SOS does not stand for any specific words. Instead, it was chosen as a distinctive and easily recognizable signal in Morse code. Comprising three short signals, three long signals, and three short signals again (· · · – – – · · ·), SOS is a clear and concise way to indicate an emergency.

The Titanic Connection

The widespread adoption of SOS as a distress signal gained prominence due to its use during the tragic sinking of the Titanic in 1912. While not the first time SOS was used, the high-profile disaster brought it into the public consciousness.

4. Mobile devices and technology

In modern times, SOS functionality is often incorporated into mobile phones and other electronic devices. This feature allows users to quickly send a distress signal, often accompanied by location information, to emergency services or designated contacts.

5. Emergency beacons and distress signals

Devices such as emergency beacons, distress flares, and EPIRBs (Emergency Position-Indicating Radio Beacons) often include the SOS signal as part of their signaling capabilities. These devices are commonly used in boating, mountaineering, and other outdoor activities to alert rescuers of an emergency.
