According to the distress signal concept, how can one confirm that they are signaling for help?

To confirm that someone is signaling for help, using one of the recognized emergency signals is effective because these signals are universally understood and specifically designed to convey distress. Recognized emergency signals include visual or audible indicators that communicate a need for assistance, such as three blasts on a whistle, three signals with a flashlight, or the international distress signal of three of anything—fires, flags, or blasts.

This method is reliable because it ensures that those in the vicinity can quickly identify that someone is in trouble and requires help. In contrast, other methods, like using a loudspeaker or waving arms, may not be as universally recognized or may not have the same level of clarity in conveying an emergency situation. Making a big fire is also a method to attract attention but may not be as clear or immediate in confirming a distress signal as the established emergency signals.
