As winter rapidly approaches in the Northern Hemisphere, snow is beginning to cover the mountains. This beautiful season draws millions of skiers, snowboarders, and hikers to the outdoors. While the winter landscape is breathtaking, it can also be extremely dangerous. Many people live near the mountains. Many come there for vacations. Winter sports are becoming more popular. It is the perfect time to review some critical mountain safety rules. Surviving in the mountains requires knowledge, preparation, and respect for nature.
Those who live in the mountains are usually aware of the risks and know how to behave, though this is not always the case. In developing countries, educational campaigns are not conducted everywhere.
There are several different types of avalanches that happen in nature. A mountain can produce rock avalanches, mudslides, or massive ice falls. However, in this article, we will focus strictly on snow avalanches and the unique dangers they present to human life.
A snow avalanche is a massive volume of snow sliding rapidly down a mountain slope. The dangers are extreme and terrifying. According to medical studies and research from scientific institutions like Eurac Research and the National Center for Biotechnology Information (NCBI), a snow avalanche is not just dangerous because of the weight of the snow. The primary threats to a human body buried in an avalanche are severe physical trauma from hitting trees or rocks, rapid hypothermia from the freezing temperatures, and most commonly, suffocation due to a lack of oxygen under the snow.
What exactly causes these terrifying events, and where do they most often occur? Official safety guidelines from the United States government preparedness website, Ready.gov, and the Avalanche.org encyclopedia explain that avalanches most frequently happen on mountain slopes that have an angle between 30 and 45 degrees. If a slope is too flat, the snow simply cannot slide. If a slope is too steep, the snow falls off constantly and cannot build up a heavy layer. The main causes of an avalanche are sudden weather changes and human activity. Heavy new snowfall, strong winds that blow snow into thick, heavy plates, or a sudden warming in temperature can all make a snowpack unstable. However, rescue organizations note a tragic fact: in the vast majority of accidents involving humans, the avalanche is actually triggered by the victims themselves or someone in their group skiing across a fragile layer of snow.
If you ever find yourself in the terrifying situation of being caught in an avalanche, knowing exactly what to do can save your life.
Let us first look at this emergency from the perspective of the person in danger. In the very last seconds before the sliding snow sweeps you away, you must try to protect yourself. If you are standing near the edge of the breaking snow, try your hardest to jump backward or to the side, off the moving block of snow. If you are wearing a modern avalanche airbag backpack, deploy it immediately by pulling the handle. This device inflates a large balloon behind your head, which helps to keep you floating on the surface of the moving snow. If there is a strong tree or a solid rock directly next to you, grab it as tightly as you can to let the snow flow past you. You must also try to get rid of heavy equipment, such as your skis, snowboard, or ski poles. These items act like anchors and will pull you deeper into the flowing snow while violently twisting your legs.
If you cannot escape and the avalanche pulls you down the mountain, your absolute main goal is to stay on top of the snow. Mountain safety experts and rescue equipment companies strongly recommend that you fight the snow with all of your energy. Do not give up. Try to make aggressive swimming motions with your arms and your legs to push yourself toward the surface. Keep your mouth firmly closed and your teeth clenched so that your airway does not fill with crushing snow.
As the avalanche finally begins to slow down, the snow will start to feel incredibly heavy and thick. In these final moments before the snow stops moving entirely, you must act fast. Take a very deep breath to expand your chest, and bring your arms and hands up directly in front of your face.
Once the avalanche completely stops, the snow will instantly freeze together. It will become as hard and tight as solid concrete. You will not be able to move your arms or your legs at all. Because you brought your hands up in front of your face, you can now use them to push the snow away from your nose and mouth to create an "air pocket." This small empty space in the snow is your only supply of oxygen. According to biological survival data from NCBI and Eurac Research, having a clear airway and an air pocket is the single most critical factor for surviving an avalanche burial. When a person breathes in a closed snowy space, oxygen drops quickly, and dangerous carbon dioxide builds up. You must stay as calm as possible. Do not panic, because panicking will make your heart beat faster and cause you to consume your limited oxygen very quickly. Do not waste your precious energy and air shouting continuously. The hard snow absorbs all sound, so people on the surface will probably not hear you unless they are digging right above your head. Take slow, shallow breaths to conserve oxygen, and wait for rescue.
Now, let us change our perspective to the people who witness the disaster.
If you see an avalanche sweep away your friends or other skiers on the mountain, your quick actions are their absolute best chance of survival. However, official guidelines from organizations like Mountaineering Scotland emphasize one critical, unbreakable rule: your own safety must always come first. You cannot help anyone if you become a victim yourself. Before you rush down onto the avalanche debris, look up at the mountain. Is there more unstable snow hanging above you? Is there a high danger of a second avalanche? You should only proceed if you are certain it is safe to do so. While the avalanche is still moving, keep your eyes firmly fixed on the victims. Watch them very closely and try to remember the exact spot where you last saw them on the surface. This is known in mountain rescue as the "last seen point," and it will tell you exactly where you need to start your search.
Once the snow has settled and you know it is safe to move, you must alert professional rescuers. Call the local Mountain Rescue team or dial the regional emergency number (such as 112 in Europe or 911 in North America). Tell them your exact location, what just happened, and how many people are buried under the snow. But remember, you cannot just sit and wait for a rescue helicopter to arrive. Avalanche survival statistics clearly prove that the highest chance of survival is within the first 15 minutes of being buried. Professional rescue teams almost never arrive that quickly. Therefore, companion rescue the immediate rescue performed by friends and witnesses already on the scene is absolutely vital to saving a life.
To effectively rescue someone, you must have the correct equipment and know how to use it. Official snow safety programs state that every single person traveling into avalanche terrain must carry three essential tools: an electronic avalanche transceiver (often called a beacon), a collapsible metal probe, and a strong metal snow shovel. First, switch your avalanche transceiver from "send" mode to "search" mode. Move quickly and systematically across the avalanche debris, following the digital distance numbers and directional arrows on your device. When the numbers on your screen drop very low, get close to the ground to find the strongest signal point.
Next, use your long metal probe to physically locate the buried person. Push the probe down deep into the snow in an expanding circular pattern until you feel a soft, bouncing resistance - which is a human body - and not a hard rock or ice block. Once you have a positive probe strike, leave the probe in the snow to mark the exact spot.
Finally, you must dig. Shoveling avalanche snow is extremely exhausting and takes a very long time. If you are alone, start digging just below the probe. If there are multiple witnesses, work together as a team in a V-shape formation. You must chop the hard, concrete-like snow and move it backward like a human conveyor belt. You should not dig a hole straight down like a well. Instead, start downhill from the probe and dig into the slope horizontally. This creates a flat terrace and allows you to pull the victim out safely without collapsing the heavy snow back onto them. Your very first priority when you finally reach the victim is to uncover their face. Clear the snow out of their mouth and nose immediately so they can breathe fresh air. Check if they are breathing. Keep them as warm as possible, wrap them in extra jackets or emergency foil blankets to fight hypothermia, and wait for the professional medical teams to arrive.
We hope this article helps you understand the serious risks of the winter mountains and how to act in an absolute emergency. Mountain safety is a shared responsibility, and knowledge is your best tool.
