A distress alert is not as easy as it sounds. Your alarm may go unnoticed. In addition, the inability to properly send distress alerts with certain types of time cards can cost you your life..
Means and methods of giving distress signals in emergency and extreme situations.
All distress signaling aids are divided into time sheets and improvised ones (type of means), as well as sound, visual and radio signals (principle of signal transmission). Their main goal is to indicate your exact location for the subsequent evacuation and emergency care in the form of food, medicine, weapons and ammunition.
Distress Radio (SOS).
The SOS distress signal (save our souls) was adopted by the International Convention in Berlin on November 3, 1906. For its unimpeded reception every hour for 6 minutes (from the 15th to the 18th and from the 45th to the 48th) at the distress frequencies of 500 and 2182 kHz, all radio stations in the world become silent. There is silence on the air so that everyone who is in trouble can freely go on the air and give a distress signal, indicating the square of their location, or allow themselves to be directed. To supply this radio signal, you must have an emergency radio transmitter and know the basics of using this device and Morse code.
Visual Alerts and Distress Alerts.
These include :
. The stronger the polished plate, the farther the light signal is visible. Lay on the hill pieces of crumpled (this will increase the number of reflective planes) foil. Or attach the foil to a tree or pole in a clearly visible space, it will rotate and give signals.
A kite can also serve you well. Make a frame out of thin boards, pull thin (preferably colored) paper on it, tie pieces of foil and bright ribbons to the tail of the snake.
Distress Signal Flags.
Hang flashing pieces of cloth on tall trees near your camp signal flags. To make them visible from above, stretch these flags on the ground. Tie one side of the matter to bushes growing near the reservoir, and the other to the stakes driven into the bottom of the reservoir.
Distress Signal Bonfire.
If you have no flags, no foil, no pyrotechnics, no nifonarika, you can light a fire that is no worse than other means. A bonfire, located in an open area or high hill, is visible from afar. In the night, a brightly burning bonfire is visible from a distance of 20 km when observed from the sky, 8 km when observed from the ground. And even better, if there are several bonfires, the distance between them in this case should not exceed 20-30 meters. However, for the idea to work, you need to maintain a constant small fire near the fires, so you can make your alarm blaze in a short time.
Terrestrial Distress Code.
In open areas, you can lay out the signals of the code table. The most commonplace HELP and SOS. The dimensions of one signal must be at least 3 meters. Remember, the larger the signal, the higher the likelihood that it will be noticed. You can make a signal from improvised means: wreckage of a plane, life jackets, clothes, logs. You can not lay out the signal, but dig it out. To do this, remove the turf and deepen the trench. Such signals work both day and night (at night you can light a fire in the recesses). Scatter signals around the periphery, the more there are, the better.
Gesture code system for communication with pilots.
Here is the landing! We need help! arms up, palms inward, legs together.
Landing is impossible! We do not need help! left arm up, legs together.
Straight arms raised, bent at the elbows, palms back. Feet shoulder width apart. Swing your forearms back.
Back arms raised forward to shoulder level. Palms forward.
Stop! arms crossed, the speed of this action corresponds to the degree of need for stopping.
Freeze up! hands to hand, palms down.
Lower wiggle down with straight arms, palm down.
Higher wiggle up straight arms, palm up.
Landing arms crossed in front of you below.
