Signal type

According to their own circumstances and the surrounding environmental conditions, different distress signals are issued. In general, three repetitions of the operation symbolize the search for assistance. When you and your team need help from the outside world to get out of danger, you should understand the basic methods of rescue and call for help, or if you are in distress or getting lost in the wild, don’t be nervous. You know that the following methods can help you quickly get rescued.

The types of signals are:

[Leave a message]

When leaving a dangerous place, leave some signal to prepare for rescue personnel to find out. Ground signals allow the rescuer to know where you are or where you were in the past. Directional indicators help them find your path. Along the way, there must be a continuous indicator. This will not only allow the rescuers to pursue them, but will not be lost when they wish to return. If they lose their way and cannot find the route they want to take, it can become a guide.

Direction indicators include:

(1) Put rock or stone fragments into arrow shape;

(2) Using small stones to build a large stone pile, put a small stone on the side to point to the direction of action;

(3) use an arrow-shaped groove deep in the trunk to indicate the direction of action;

(4) Two crossed wooden sticks or stones mean that this road is not accessible.

(5) Signals conveyed by three rocks, sticks or wood jams have obvious meaning, indicating danger or emergency

(6) Support the rods in the tree fork, with the top pointing in the direction of the action;

(7) In the upper part of the roll grass, tie the knot to make the top end bend to indicate the direction of movement;

(8) Place a forked branch on the ground and use the bifurcation to point to the direction of action;

[Fireworks Signal]

Fire light is very effective as a contact signal. When in distress, depending on the situation: To ensure its reliability, put some moss, green branches, rubber, etc. on the fire during the day to make it produce thick smoke; at night you can put some dry firewood to make the fire prosperous and make the fire prosperous. high.

Three sets of fired flames are internationally used for distress signals. The fire piles are put into triangles. The interval between each pile is equal and ideal. This arrangement is also convenient to ignite. If fuel is scarce or if oneself is seriously injured, or because of hunger and excessive weakness, it is not enough to get three flames, so it is OK for Jane to light a pile. Don't allow all signal fires to burn all day, but you should always be prepared to keep the fuel dry. Once any plane passes by, it will be ignited as soon as possible. The fuel in the fire should be easy to burn, and it should be able to burn quickly after it is ignited, because some opportunities are fleeting. Birch bark is an ideal fuel. Gasoline can be used, but no gasoline can be dumped on the fire. Wicked with some fabric, soaked in gasoline, and then placed on the fuel heap, the gasoline tank moved to a safe place and then ignite. If the fire is good after ignition, it will be extinguished. Before adding the gasoline, be sure to add it to the fuel without sparks or embers.

During the day, smoke is a good locator, so the fire must be filled with smoke-emitting materials. After the smoke rises, it is in sharp contrast with the surrounding environment and it is easy for people to pay attention.

Bright smoke is noticeable at night or in the dark green jungle. Adding green grass, leaves, moss and ferns will produce smoke. In fact, any damp thing produces smoke. The damp mats and seat cushions can be burnt for a long time. At the same time, it is difficult for flying insects to approach wounds.

Black smoke is the most visible in the snow or in the desert. Rubber and gasoline can produce black smoke. If limited by the air conditions, the smoke can only float near the surface and can increase the fire, so that the warming flow will rise even more violently and will carry smoke to a considerable height.

[ground-to-air signal]

The letters listed below are the most common international SOS signals. "FILL" can help you remember the main signals. A single wooden stick "1" is the most important one, and the production is also the simplest one. The dimensions are 10 meters long and 3 meters wide for each signal and each signal is 3 meters apart.

[sound signal]

If you are close to each other, you can cry loudly, three shorts and three longs, and then three short ones; repeat after one minute.

[Reflective signal]

Use sunlight and a mirror to emit signal light. Any bright material can be used, such as can lids, glass, and a piece of metal platinum. Of course, a mirror is more ideal. The continuous reflection will regularly produce a long line and a dot, which is a kind of Morse code. Even if you do not understand Morse code, feel free to reflect, it may also attract people's attention. In any case, you should at least grasp the SOS code. Even if you are far away, you can perceive a reflected light signal. Even if you do not know where you want to contact the target, it is worth a lot of temptation, and its approach is only to do little. Focusing on looking at the sky, if there is a plane approaching, it will quickly reflect the signal light. This light may dazzle the rescue personnel, so once it is determined that they have been found, they should immediately stop reflecting light.

[Signal signal]

When the search aircraft is closer, the meaning of the person in distress can be expressed in body language.

[Semaphore signal]

A flag or a brightly colored cloth is attached to a wooden stick. When holding a rod, a long stroke is made on the left side and a short stroke is made on the right side. This increases the range of motion and makes the “8” motion. If the two parties are closer together, it is not necessary to do "8"-shaped movement. A simple stroke can be done, with a long stroke on the left and a short stroke on the right. The former should be slightly longer than the latter.
