How to cross the river before it is safe

In the outdoor activities, rivers crossing rivers are often encountered. The use of safety science crossing technology is a good guarantee for safety. Crossing the river is dangerous, so don't cross the river when absolutely necessary. Wet body in the cold can lead to fatal hypothermia.

Before crossing the river, consider ways to let the body dry after going to the other shore, such as exchangeable clothing. When it is cold, save the fire, and consider heating afterwards.

When crossing the river, put on shoes to prevent stone scratches, take off trousers to prevent getting wet, and trousers will increase resistance in the water. (You can consider not taking off pants to play a certain role in keeping warm, fast-drying pants, Trousers It's fast, but it's best to tighten your trousers and reduce resistance.) Use a cane to help support.

Safety instructions

1. If the river is clear, don't go barefoot when the bottom of the river is gravel, so as not to hurt the bottom of the foot with rubble or other objects. If the bottom of the river is mud, take off your socks to prevent the shoes from being lost in the mud. But in the event that the river is too cloudy to observe the bottom of the river, do not cross the river barefoot anyway.

2, in the water can not raise the foot, or the center of gravity will be unstable. Instead, it is necessary to drag the pace and slowly move the footsteps. Try to place the body of gravity on both feet. When wading, it must be straddled step by step. It must not be crossed before to reduce the momentum of the current. The large rocks in the stream often have slippery moss, and you must avoid stepping on big rocks.

3. If you cross the river in winter or when the weather is cold, remove your warm clothing including shoes as soon as possible and wear it immediately after you get through it. Once the warm clothing is soaked, it will cause severe temperature loss.

4, in the entire process of crossing the river, including the case of crossing the river, must be to untie the backpack's belt, this time the backpack may be a fatal burden, this point for all crossing the river, remember.

5. In the event that the body loses its balance during the wading crossing and even accidentally slips, and the water flow is in a hurry, it is easy to incur misfortune. Therefore, it must be extremely calm and it must not be flustered. In any case, we must first try to stand firm at the bottom of the river before we can calmly find ways to climb the shore.

One, single river crossing technology

Look for strong long sticks, supported by shoulders. Long sticks are placed about two meters in front of them. The body is leaning forward against the long sticks, forming a firm triangle with the legs, crossing the river facing the direction of the river, and following the two points when crossing the river. The principle of moving a little bit moves and the third point can only be moved after the other two points have stabilized. At the same time, pay attention to the fulcrum formed by the two legs and the long stick to maintain balance, and the crossing line is always kept perpendicular to the direction of the water flow to reduce the impact force.

Face up and grab the poles vertically in front of you to create a solid triangular support. Move one step at a time. Move only one foot at each step. Be restrained not to let one foot get too close to the other. Then move the brace back to the top of the triangle. Ensure that the foot is stable and the struts are stable before moving on. (The figure means: The person stands facing the upstream of the current, and the two feet and the struts form a triangular support on the bottom of the water, and the person moves laterally across the river)

As shown in the figure, a person should face the river in the direction of water flow and move across the river to the left. It is also possible to walk forward at a special time (such as a rocky step on the foot). However, avoid going backwards, otherwise it is easy for water to fall over.

Second, double river crossing technology

The safest method is a variant of the single crossing.

The first method: A person stands in the above position. The second person stands behind him and also faces upstream. He firmly grasps the shoulder strap of the person in front and leans forward to give support. I also want to slowly leap over the same thing as above.

The second method: If there are no struts available, the two people stand face to face at right angles to the water flow and hold each other's shoulder straps tightly to each other. Keep feet apart to maintain a stable four-point support. It is important to ensure that both sides are facing the water. If one turns to face the water, the other person's knee will be easily bumped by the current.
