How to ensure safety in the event of a blizzard?

In mountaineering activities, the phenomenon of sudden winds and snow blowing or snowfall is called a snowstorm. The snowstorm weather is prone to frostbite, slipping, being buried in snow, getting lost, and the snowstorm has brought great difficulties and dangers to marching and camping. Therefore, mountaineering should scientifically grasp and use the weather, choose a standby camp, and master the principle of camping, especially the selection of high-altitude campsites, and also organize the contingents.

When encountering snowstorms during the mountaineering, first of all, it is necessary to do a fixed protection and pay attention to preventing frostbite. If the wind is encountered during the journey, the wind is blowing into the body and it feels cold, indicating that the clothes to be worn are not enough and should stop immediately and add clothes. Because the heat generated by the march can not drive the body temperature, the body must feel the slightest heat when sweating outdoors. When it stops to rest or the weather suddenly changes, it will not suddenly feel uncomfortable. There is a saying "I would rather heat sweat, and don't blow cold." When the wind is too large to put up the tent, the tent's external account can be taken out. Everyone circumscribes the foreign account on everyone's body to block the wind. At this time, people who don’t wear clothes in time will have a way out. Clothes are put on.

When a sudden blizzard occurs during camping, tents should be reinforced and it is strictly forbidden to leave the camp or perform climbing activities. Keep cold equipment and plan the use of fuel and food. Clear the snow covering the tent in time to prevent the tent from being collapsed by the snow. In the event of heavy snowstorms, the wind is strong and the tent must be managed to prevent the wind from blowing the tent.

Avalanche must be guarded against during mountaineering

An avalanche is a serious threat to climbers. Among the dangers encountered in high mountain adventures, the damage caused by avalanches is the most frequent and tragic, and often results in “all annihilation.”

Before climbing, you should master and understand the regularity and timing of the avalanche in the area. Most avalanches occur in winter or when snowfall in spring is very large. Especially before and after the storm broke out. The snow at this time is very soft, and the adhesion is relatively small. Once a small piece is destroyed, the rest will be like a scattered sand or a domino, causing a chain reaction and falling rapidly.

Avalanche is very dangerous. People who work in the snow must pay great attention to the following points:

The law of avalanche occurs: Do not go uphill after the snow has passed, or after several consecutive snowfalls. At this point, the new snow or the snow on the upper layer is not strong, and slight disturbances are enough to trigger an avalanche. After the snow is often accompanied by good weather, we must give up the good weather waiting for the avalanche.

When the weather is cold, the weather turns fine, or when snow begins to melt in the spring, the snow becomes very unstable and avalanches can easily occur.

Signs of an avalanche: Watch out for signs of avalanches, such as the sound of snow and ice or a deep roar. Snowballs roll down or look up at the dusty gray dust on the mountain. The road through which the avalanche passes can be identified based on topographical features such as cliffs, relatively smooth terrain, or faults on very few tree-facing slopes.

How to prevent avalanches:

Generally within 2-3 days after heavy snowfall, do not operate in areas prone to avalanches and snow slopes.

Pay attention to avoiding the avalanche area and the avalanche groove during the march. Try not to damage the snow layer and use a straight line to climb. When it is impossible to avoid the avalanche zone, it is necessary to adopt a crossing route and must not climb along the avalanche slot. When you cross, you must travel at the fastest speed, and set up a dedicated lookout stance to keep an eye on the area where the avalanche may occur. When there is an avalanche or if an avalanche has occurred, you must give a loud warning so that you can quickly take self-rescue measures. If you must go through the avalanche area, you should cross it after 10am. Because at this time, the sun has been exposed to snow-capped mountains for some time. If there is an avalanche, it will happen before this time. This will also reduce the risk.

Do not move on steep slopes. Because the avalanche usually moves downwards, an avalanche can occur on a 1:5 slope. If you have to cross a slope, do not act alone or squash together. You should walk one by one. The person from the next departure should maintain an observable safety distance from the former.

In alpine adventures, leeward slopes should be avoided whenever climbing routes or camps are chosen. Because the leeward slopes tend to accumulate snow from the windward slope, avalanches are also likely to occur. When possible, walk along the ridgeline if possible and walk at the highest point of the mountain.

When choosing a march route or camp, be wary of the selected flat area. Because in the steep high mountains, avalanche accumulation areas are most likely to appear relatively flat.

When marching in high mountains and resting, do not speak loudly to reduce avalanche triggered by air shocks.

The best of each player in the march is tied with a red cloth in case it is easily found in case of an avalanche.
