In the wild, the living environment is very bad, and various disasters will come unexpectedly. For the wild survivors, it is crucial to know the dilemma they face and inform others. When you are in distress, you have to get in touch with others in various ways. The signal sent should be enough to draw people's attention. At the same time, different distress signals should be issued according to their own conditions and surrounding environmental conditions. In general, actions repeated three times symbolize the search for assistance.
1
Fireworks signal
The three flames are the international common distress signal. The fire is placed in a triangle, and the interval between each pile is ideal. This arrangement is also convenient for ignition. The fuel of the fire should be easy to burn, and it should burn quickly after ignition, because some opportunities are fleeting, and birch bark is an ideal fuel. During the day, smoke is a good locator. Adding some green grass, leaves, moss and ferns to the fire will produce thick smoke. After the smoke rises, it forms a strong contrast with the surrounding environment and is easily noticed. In the evening, you can put some dry wood, so that the fire will burn and the fire will rise. In addition, black smoke is most visible in snow or desert, and rubber and gasoline can produce black smoke. If weather conditions are limited, the smoke can only flutter near the surface, which can increase the fire, so that the heating flow will rise more vigorously and carry smoke to a considerable height.

When the search aircraft is near, the hands are greatly waving the clothes with a large contrast with the surrounding environment, expressing the meaning of distress.
3
The semaphore signal is tied to a wooden stick on a flag or a brightly colored fabric. When the stick is in motion, it is long stroked on the left side and shortly stroked on the right side to increase the amplitude of the movement and make an 8-eight-shaped movement. If the distance between the two sides is close, there is no need to do an "8" shape movement. A simple stroke can be done by long strokes on the left side and short strokes on the right side. The former should be slightly longer than the latter.
4
If the sound signal is close enough, you can shout loudly or hit the trunk with a wooden stick. The life-saving whistle will be more obvious. The three sounds are three short and three long, and the sound is short, and the interval is repeated after 1 minute.
5
Pattern signals can sometimes be lost in the wild, and the hikers need to use various methods to get in touch with the outside world. Patterns are often used in the wild. In "Haier Brothers", in order to fight pirates, Haier brothers finally got rescue by drawing a "SOS" distress signal on the deck of the cruise ship. In the wild, if we get lost, we can also use the various objects to display various distress signals on the open ground and request external support. Ground signs can be made on open ground such as grass, beaches and snow. If the grass is cut into a certain logo pattern, or the help-seeking sign is stepped on the snow, it can also be used as a sign signal with branches and seaweed to get in touch with the air.

Remember these words using an internationally uniform identifier: SOS, SEND, DOCTOR, HELP, INJURY, TRAPPED, LOST, WATER water).

The illuminating signal is combined into three light-emitting points by using a smooth surface such as a mirror, an inner surface of the can, and the like, and the signal is continuously transmitted to the periphery. The regularity produces a long line and a dot is the famous Moore code, which can attract the attention of others.

When the signpost signal leaves the dangerous place, leave some signal for the rescuers to discover. Ground signals allow rescuers to know your location or past location, and direction indicators help them find your path of action. Keep markings along the way, this will not only allow rescuers to pursue, but also avoid getting lost when they want to return. If you lose your way and can't find the route you want to go, it can become a guide.
In addition to mastering the necessary survival skills, you must not forget the outdoor tools that must be brought!
The size of the rucksack of the rucksack is directly related to the number of days in the field, and should not be less than 50 liters.
The ropes are generally about 20m long. Mountain climbing is different from rock climbing. Cliffs over 10m are “forbidden zones†for ordinary people.
Hiking shoes, outdoor products, jungle jungle boots, rubber soles and stab-resistant steel plates, leather uppers, cotton shoes, non-slip breathable, can protect the feet and cheekbones.
The flashlight and the light stick can be used as a light source for illumination or rescue in practical applications.
The compass needle has the greatest effect when used in conjunction with the corresponding map. You should also fully understand the use of the compass before departure.
Survival whistle When exploring the road and looking for water, the length of the whistle and the different combinations are the most convenient and simple communication methods in the field.
Survival tool survival tool, full keel, heat treatment qualified, length 20~24cm, no multi-function such as back teeth (more function, less reliable).
The tent user should select the applicable type according to the season and climate of the area to be visited, and learn how to build before departure.
Sleeping bags and mats for survival in the wild must at least meet the basic functional requirements of moisture-proof, moisture-proof and breathable, light weight and small size.
The fire tools used in the field of life tools are mainly matches or lighters.
An ordinary person in a kettle consumes at least 2 liters of drinking water a day, so the kettle is a must-have tool for field activities.
Telescopes are in the wild, observing wildlife, looking for water, and determining the direction of action.
For foods in the field of spare foods, food-carrying plans should be made according to individual tastes and specific itineraries. These foods should not only be able to provide fruit, but also provide the heat necessary for field activities.
