Prepare for the unexpected with systematic practice
You’re on the second lap of the day and you and your partner’s confidence in the conditions is increasing. It might be approaching one of those all time days in the backcountry. At the top of the next run, your partner suggests descending a little bit skier’s left this time into a slightly steeper pitch. You sheepishly agree because it looks so good! Your partner drops in and makes three turns before cracks in the surface shoot across the slope. An avalanche is happening and your friend is caught in the middle of it…
Avalanche rescue skills are a reactive approach to safety in the backcountry, but a critical one for anyone who ventures into avalanche terrain. When was the last time you practiced a full avalanche rescue scenario? Probably in your last avalanche course. Setting time aside with you and your partners to practice at home will ensure each of the steps has a better chance to stick.
Here are five key elements of your avalanche rescue and tips to recreate scenarios at home.
The majority of professional training organizations follow a similar approach to avalanche incident management with some nuances that are worth exploring. At bare minimum the avalanche rescue skills you practice should include the following:
· Scene safety and size-up
· Beacon Search
· Patient care considerations
If any of the above points or below actions sound unfamiliar, sign up for a reputable one-day Avalanche Rescue Course with an American Avalanche Association approved provider. This will keep you up-to-date on the most current research in the field.
Practice how you want to perform. Verbalize each step of the way!
Scene Safety and Scene Size-up
As you watch your partner fighting to stay on top of the slab, your mind starts racing. Every part of you wants to slide downhill after them to start helping.
This moment is arguably one of the most important aspects of a rescue and one of the most difficult to practice. If you have wilderness medicine training, the scene-size up will look familiar. Your verbal and mental checklist should include the following:
· Risk of exposure to additional hazard (avalanches, terrain hazards, environmental hazards, other groups, etc)
· Designate a leader of the overall rescue – someone who may not be directly involved in rescue
· How many people are caught/buried?
· Determine the last point scene of the victim(s)
· Decide to call for outside help and note the time
Time starts ticking as soon as your partner is in the avalanche. A quick and efficient transceiver search is crucial to increase your partner’s survival margins.
If you don’t start with a signal, you have to systematically search the debris area using search strip widths of about 40m. Once you acquire a signal, keep the arrow in the middle and follow its direction to see the number get smaller. As you get closer and within the number 10 on your transceiver, slow way down and be very precise. Keep your device oriented the same way, and once the number stops getting smaller, stop and mark your lowest number with a ski pole.
· Practice on a slope in both uphill and downhill mode for a more realistic scenario
· Turn all other electronics are off to avoid signal interference and make sure all beacons are in search
· Hold your beacon flat and at arm’s length in front of you
· Verbalize the numbers on your beacon and coordinate with fellow searchers
· Slow is smooth and smooth is fast – give your device time to process the buried signal
Your transceiver tells you that you’re on top of the victim but all you see is snow. When’s the last time you practiced deploying your probe and using it to locate something?
Practice deploying your avalanche rescue equipment by starting with your pack fully packed and on your body. Remove your pack, retrieve your probe and assemble it quickly and effectively by holding onto the top section and tossing the rest while pulling on the cable to lock it. Start at the lowest beacon point that you’ve marked and probe perpendicular to the snow surface in a systematic pattern. Probing is both a tactile and visual skill. You’re feeling for something soft and squishy!
· Bury a larger object than just a backpack for a more realistic scenario
· Move systematically in a square grid pattern expanding by 25cm’s
· LOOK for changing depths of the probe
· FEEL for changing textures below the snow – we are aiming for SQUISHY and SOFT
· Yell STRIKE once you have successfully probed the victim
You hit something soft and it’s time to start shoveling. This is the most time consuming aspect of a rescue. Shoveling to excavate the snow and uncover a person requires organization, stamina, and practice.
Start one or two large steps down-hill from the probe and chop blocks of snow and sweep them down hill. Organize additional rescuers behind you to begin creating a conveyor belt of snow and try to flatten a platform for your victim once they are uncovered from the snow.
· Find a road plow bank of snow to simulate realistic avalanche debris.
· Sweep the snow behind you and downhill (like paddling a canoe)
· Practice with your backcountry partners in an organized way
· Time yourself how long it takes to get to the bottom of a probe that is 1.5m deep
You reach your partner but his eyes are closed and his face is pale. What now?
Once you have uncovered your victim from under the snow, the real journey begins. They could be suffering from trauma, asphyxiation, and cold related injuries. Your ability to care for someone effectively depends on the level of medical training you have, and the equipment you carry with you. It is critical to assess their vitals. Are they breathing? Do they have a pulse? Is the airway clear? You should carry a proper CPR mask, a way to control severe bleeding, and shelter/extra layers to protect someone from the cold environment.
· Using a real size CPR mannequin is a great way to practice patient care
· Practice building an emergency shelter
· Package a patient into a rescue sled or litter to evacuate them
Does this seem like a lot? It is! Too often we only practice with our beacons, but there is far more to an avalanche rescue incident. We need to practice all of the elements in order to be the most effective rescuer.
A few final tips
· Practice in a safe location NOT in avalanche terrain.
· Bury a large duffel with a beacon, not just a small object – it is not realistic!
· Bury the beacon at least one meter or more under the surface.
· Practice in an area large enough so you don’t start with a beacon signal right away – use your search strip widths to systematically search the debris field so you don’t miss a possible signal.
· SLOW DOWN in your beacon searches – slow is smooth and smooth is fast.
· Be thorough with your practice and verbalize all of the steps – it helps to create mental muscle memory.
· Get medical training!
What other tips do you all, readers, have for avalanche rescue practice?
Remember this is a perishable skillset, don’t let it go stale. Practice and seek professional training!
December 2020 has thus far incurred the most avalanche deaths in Colorado in a single month since modern avalanche reporting began. Avalanche rescue skills are critical to being a competent partner, but are a reactive approach to safety. It is more important to take a proactive approach to managing your safety in the backcountry. Get educated, stay safe, and know how to effectively use your tools.
