vészjelzésnek

Vészjelzésnek is the dative form of vészjelzés in Hungarian, meaning a distress signal. It refers to any signal, message, or transmission that communicates an urgent need for assistance in life-threatening situations. Vészjelzések are used in maritime, aviation, and land-based rescue, and are governed by international and national conventions to enable rapid recognition and response.

Signals can be visual, audible, or electronic. Visual examples include signal flags, flares, orange smoke, or lights. Audible forms include sirens, horns, or shouted calls. Electronic systems include EPIRB and PLB beacons, satellite-based distress systems, and DSC on marine radios; in Morse code SOS, or voice Mayday.

Internationally, distress signaling is regulated by ITU and IMO. The SOS Morse code sequence is ... --- ..., and Mayday is used as a voice call. Distress channels on maritime VHF radio include Channel 16, and emergency beacons operate on designated frequencies. Signals should convey location, nature of danger, and number of people involved when possible, and must be used only in real emergencies.

In Hungary, vészjelzésnek relates to civil protection and emergency response. The national emergency number is 112. Proper training, equipment, and procedures ensure that legitimate vészjelzések trigger timely assistance, while misuse can be sanctioned.
