Distress signals are methods used to communicate that someone is in danger and needs help. These signals can be visual, auditory, or electronic, and they are designed to attract attention. Common examples include waving arms, using a whistle, or displaying a distress flag. In maritime contexts, the International Maritime Organization has established specific signals, such as the use of flares or the SOS signal in Morse code. In addition to traditional methods, modern technology has introduced new ways to send distress signals. Devices like personal locator beacons (PLBs) and satellite phones can transmit location information to emergency services. These signals are crucial in situations like boating accidents, hiking emergencies, or natural disasters, ensuring that help can be dispatched quickly.
