SOS

SOS is an internationally recognized distress signal used to summon help in emergencies. The acronym stands for "Save Our Souls" or "Save Our Ship," reflecting its maritime origins. The signal consists of three dots, three dashes, and three dots, transmitted in Morse code. It is used in various contexts, including maritime, aviation, and land-based emergencies. The signal is standardized to ensure clarity and prompt response from rescue services. In addition to the Morse code signal, SOS can also be represented by the flag sequence of three red crosses on a white background, or by the international distress signal flag, which is a red square with a white diagonal stripe. The use of SOS is governed by international regulations and agreements, such as the International Convention for the Safety of Life at Sea (SOLAS) and the International Aeronautical and Maritime Search and Rescue (IAMSAR) Manual. The signal's simplicity and universality make it an essential tool for emergency communication worldwide.
