The living environment in the wild is very harsh and disasters can happen unexpectedly. For field survivors, finding a dangerous situation and seeking assistance in a timely manner is crucial.
Usually, different distress signals are issued according to their own conditions and the surrounding environmental conditions. In general, any three repetitions of the operation symbolizes seeking assistance. According to your position, you can ignite three piles of fire, make three smokes, or make three loud whistles or three gunshots. If you use sound or light signals, after sending three signals in each group, stop for 1 minute and repeat.
Fire signal:
Fire light is very effective as a contact signal. Distress may be based on its own circumstances: To ensure its reliability, during the day, put some moss, green branches, rubber, etc. on the fire to make it produce smoke; at night you can put the firewood to make the fire prosperous. Although it is impossible to keep the fire burning all the time, it is possible to prepare dry fuel. Once there is an airplane passing by, it can light the fire as soon as possible.
The discharge of three stacks of flames is an internationally accepted distress signal. The triangle of the fire will be placed in a field, and the interval between each pile should be as equal as possible to facilitate ignition. If there are special circumstances, such as the scarcity of fuel, the seriousness of the survivors, or the fact that the survivors are frail due to excessive hunger and cannot get enough of the three piles of flames, then a simple pile is also feasible.
The torch tree is a good natural fire if it is isolated on one side. It is not possible to ignite in the woods. This will not only endanger the forest, but it will also cause the fire to be too large, thus threatening the lives of the living people. Stack dry twigs between the branches. The nest is the best firelighter. Lighting these firelighters will further burn the branches and produce smoke; if the small trees are dead, they can be ignited from the roots. The small tree can continue to burn for a long time, and its gap is enough for the survivors to take care of other fires.
The conical fire erects a three-legged support in an eye-opening area, and a platform is placed above the support to set the fire so that the fire can be separated from the wet ground. It is also convenient to place fuel at the bottom and choose a favorable time to ignite. Supports should be maintained more, but also ensure that the fuel is dry enough. Do not use these reserves for other purposes. Insert the support rods underground to prevent them from being blown down by strong winds. After the conical fire was ignited, it could be seen several kilometers away.
Using wreckage to make fire signals The wreckage of an airplane or car can also be fully utilized. Stacking fuel ignition on metal debris can effectively isolate the wet ground and enhance convection, and the smooth metal surface can also be used as a mirror to make the flame brighter and easier to find.
Smoke signal
Smoke signals work best in daytime visibility. After the smoke rises, it is in sharp contrast with the surrounding environment. Smoke is a good locator. Adding smoke to the fire can help the cruising rescue aircraft find the survivors and at the same time understand the surface winds and arrange suitable rescue points.
Bright smoke Any damp thing can produce smoke. If it is at night or in the dark green jungle, use bright smoke to be very eye-catching. Adding leaves, moss, and ferns to the fire can produce heavy smoke. The damp grass mats and cushions can be burnt for a long time. At the same time, the smoke insects can hardly approach the wounded people.
Black smoke is the most visible in the snow or in the desert. Gasoline and rubber products can produce black smoke. If the weather is not good, smoke will only drift close to the surface, you need to add fuel to increase the fire, so that the heat flow to bring the smoke rise to a certain height.
Land-to-sky code
"FILL" can help you effectively remember the major international emergency signal. A single stick "I" is the simplest but most important code. It stated that the injury was serious and the patient needed to be transferred immediately. It also indicated that the doctor was in urgent need.
After getting in touch, send a signal to the aircraft to use subtitles A (affirmation) or N (negative) to communicate their own responses, or use a Morse code or body language. After being rescued, these signals must be destroyed in time so as not to attract other rescue personnel.
Evening signal
On dark nights, the fire light can easily attract the attention of the surrounding people. If there are petrol or other flammable substances around, you can make a distress call at night. Put a "SOS" or other symbolic signal on the ground, choose the right time, pour the gasoline and other substances and then ignite. Such signals can continue to be noticeable even when the survivors sleep or are injured.
Communication signal
Do not trust your memory too much. It is best to carry code transcripts with you in the wild. If you can't remember the complicated semaphore signals, you can send messages by shouting loudly, waving flags or shirts on the sticks. Here are some procedures and precautions to follow when sending or receiving signals. Understanding these special codes will make the rescue operation easier and more convenient.
The simple light return signal of the refractometer can also be used when it is far away or when ice does not know the target position. The operation method is simple and can be repeated many times. Any smooth surface material can be used as a mirror. Such as can lids, glass, aircraft or car metal debris, of course, if there are mirrors would be more ideal.
The semaphore semaphore signal is very simple and easy to use. It only needs a flag or brightly colored fabric to be replaced by a wooden stick. It is left and right waving, and the long stroke on the left side and the short stroke on the right side increase the amplitude of the movement. The shape is “8â€. Exercise can be. If the target is far away from the target, the simple left side long stroke, the right side short stroke, the long stroke stay slightly longer, do not have to do "8"-shaped movement.
