SLF workshop on avalanche rescue - When was your last time?

Behind the scenes at the Institute for Snow and Avalanche Research SLF

by Steffen Kruse 01/24/2019
Anyone who spends any time in the snowy mountains and therefore in potentially dangerous terrain should regularly deal with the topic of rescue and recovery. I myself pack my backpack before the start of winter, check the equipment for wear/function and fit the avalanche transceiver with new batteries (lithium ions). Then I meet up with friends to practise, exchange ideas and learn new things.

We repeat this procedure several times during the season. That's how we do it, but how do the professionals, the employees of the SLF do it?

For many years, the SLF has organized a somewhat unusual "company outing" for its employees at the beginning of the season and offers them a training day in the snow. The event is voluntary and suitable for different skill levels, from beginners to mountain guides or even avalanche experts. This day is entirely dedicated to the topic of rescue and the question: What to do in an emergency? Of course, it is best not to get into such a situation in the first place, which is why separate prevention workshops are also offered.

This year, we were able to mingle with the SLF employees and take part in the rescue workshop. In small groups, we explored different aspects of avalanche rescue at various stations. The first station was about forming an improvised sounding formation (open sounding), for which we were instructed and guided in detail by Lukas Dürr.

We then moved on to the correct shoveling technique. To summarize, I can only say: "step on the gas, take turns leading and create space!" The victim should be uncovered as quickly as possible. This is best done in a V-shaped conveyor belt. Do not throw the snow over the head of the person behind you, but "wipe it away" backwards. Vali Meier (Head of Rescue at Davos Klosters Bergbahnen) gave important tips and background information. The primary goal is survival, only then comes the rescue. Not new, but always good to internalize. The primary goal is to free your comrade and to do so as quickly as possible.

The next station was about organizing ourselves as a group in order to carry out a multiple burial exercise quickly and effectively. We were also quick at this, at least at first, until we realized that we had "lost" one person. Two people were relatively close together and we lost the signal of the second person due to the marking function. We had forgotten to switch off the avalanche beacon of the person we had found and then search again. Another input in the debriefing was that one person should take over the coordination (if possible), assign the tasks directly and keep an overview.

Another station dealt intensively with topics relating to the avalanche transceiver. Here, the double group check was refreshed. The influence of the cell phone on the transmission and reception performance of the avalanche transceiver was also a topic. In summary, a cell phone is important for alerting the rescue team, so it should be switched on and charged. Ideally, however, the distance to the avalanche transceiver should be more than 25 cm. Other electrical and metal devices can also affect the avalanche transceiver, be it helmet cameras, heated gloves or the shovel blade.

I was also personally disillusioned by how bad these "great" polarized goggles are, because I saw pretty much nothing on my avalanche transceiver display during the search. Be sure to check for yourself with your own device when you buy new sunglasses!

The theoretical repetition of elementary avalanche rescue using a diagram was also very valuable in order to bring the procedure back to mind. Afterwards, everyone was allowed to show off their skills in a search exercise, was closely observed by Jürg Schweizer (SLF Institute Director) and then received individual feedback from him.

PowderGuide would like to thank its partner SLF for this instructive day!

When was the last time you organized a proper avalanche rescue exercise or attended a workshop with your crew?
