The radio engineering means of emergency communication, signaling and distress signals include various radio stations, beacons, transceivers, mobile phones and other means.
The procedure for negotiating and transmitting distress signals using electronic means of emergency communications and signaling.
If you have the opportunity to negotiate with rescuers in radiotelephone mode, you should try to tell them:
Local meteorological conditions.
The state of the victims of the disaster (the number of wounded, disabled, etc.).
Possibility of preparing a landing site.
Estimated location of the victims of the disaster and their number At sea on the speed and direction of the drift of the vessel or collective rescue equipment.
On the marks of the accident. The most noticeable landmarks from air and land used by injured sign signals and other ways of attracting attention. For a ship or any other vehicle about its type, hull color, flag, name.
When working in radiotelephone mode, it is necessary to formulate the message in advance and possibly as briefly as possible and state it in a calm manner to the person who has the most legible diction. It is not worth clogging the air with moaning, complaints, curses, calls for help, etc. emotions. Information should be concise, specific and clearly interpreted. It depends on how quickly rescuers can find and provide assistance to the victims of the disaster..
Distress signaling time using emergency radio and alarm electronic equipment.
When using emergency radio equipment, alarms and distress alerts, the distress alert timing must be considered. For more effective reception of emergency radio signals in the world practice, the so-called minute of silence, or the international period of silence.
This is a three-minute period from the 15th to the 18th minutes and from the 45th to 48th minutes for each hour. Then the radio telegraph stations on ships, planes and helicopters of rescue and ice services, drilling platforms at sea, as well as coastal radio stations stop transmitting and work on receiving emergency messages.
Accordingly, for radiotelephone stations, the silence period is set from the 0th to the 3rd minute and from the 30th to the 33rd minute of each hour. During these periods, only distress and alert signals are permitted. In addition, there are a number of special guidelines governing the operation of ship and coastal radio stations in a given time period, providing the most favorable distress signal reception.
Mobile Phone Distress.
From the point of view of transmitting a distress signal, mobile phones that are quite common today may turn out to be useful. When using mobile phones as emergency radio communications, you should seek help by calling the ambulance, police, rescue forces, civil defense, and others..
And explain your situation as briefly and accurately as possible. Long conversations over the phone are not recommended for the sake of preserving the resources. They may be needed for additional survival advice, distress alerts in the beacon mode and as an orientation tool.
