What is the 'SOS' signal, and when should it be used?

The 'SOS' signal is recognized internationally as a universal distress signal primarily used when an individual or vessel is in need of urgent assistance. It is a Morse code distress signal, represented by three dots, three dashes, and three dots (··· --- ···). This sequence is easy to recognize, making it effective in situations where immediate help is needed, such as during emergencies at sea or other circumstances where survival is at stake.

The use of the SOS signal is critical in scenarios where life is threatened and assistance from rescue services or other vessels is required. Understanding when to use this signal can be lifesaving, as it indicates that the situation is serious and that immediate action is necessary. The clarity and global recognition of the SOS signal underscore its importance in maritime safety, ensuring that those in peril can effectively communicate their need for help.
