Avalanche protection

For centuries, avalanches have been a threat to settlements and people
in nature there is a danger. In Switzerland alone died in the winter of 1999
98 people were killed by avalanches and more than 1,500 houses were destroyed. Therefore
tries to contain the danger of avalanches with constructions made of steel, concrete and wood.

Avalanche prevention and avalanche warnings

In order to ensure avalanche protection for people in the Alpine countries,
Canada, the USA and Japan made a great effort.
In snowy, alpine regions you should be very careful and the prepared
Do not leave the ski slopes without a location code. One should pay attention to warning signs at risk
Do not enter slopes. Unfortunately, regions with a risk of avalanches are popular with athletes,
which is why people have to weigh up what risk they may be taking. The snow cover forms
no coherent, pliable mass and is therefore difficult to assess, which is why
cannot clearly predict the danger. Training to increase fitness, experience
in the terrain and good safety equipment are an important basis for
minimizing the risk. Of course, maintaining safety distances also serves
a good track system and a forward-looking driving style on a slope of a better

The following avalanche protection measures can be taken by the local
Authorities are initiated:

Passive avalanche protection measures:

They serve to a large extent to prevent avalanches, which is why endangered regions
Building permits can be revoked. In addition, evacuations can be arranged
or concrete walls are erected to prevent avalanches, the streets are bridges
or similar protect.

Active avalanche protection measures:

Used to prevent avalanches, with forests offering the best protection. Also
nets, grids or stable barriers made of wood, concrete or steel are built in ski areas,
whereby the snow cover is either divided or snow accumulations at critical points
be avoided. In addition, avalanche blasts are used, with explosive tunnels at critical
places is transported to trigger smaller avalanches. Thus, the dense snow cover
relieved and you prevent uncontrolled avalanches.
The protective measures can be taken by the department with the closure of individual areas or
detonations by avalanche safety teams should be considered.

Behavior in the event of an avalanche

One should react in these ways when threatened by an avalanche:

If you are on the edge of an avalanche slope, you can drive through fast
away from the avalanche to reduce the risk of being buried.
According to statements by those buried, swimming in the masses of snow is pointless, as is
like "riding" with skis on the avalanche. It is better to
use, such as an avalanche aribag activated by pulling the deployment handle and
inflates the air cushion on the backpack. This can avoid a deep burial. Another
Possibility is that you put a kind of snorkel in your mouth and thus also under the
can breathe snow, whereby the breathing air is discharged at the back.
If it is possible, the athlete should detach himself from the lanyard on the ski and the sticks
throw away. If there are other people in the vicinity, a
emergency call to be made. You can also help by entering the exact location
observed during the burial, which can later severely limit the main search area.

Avalanche Rescue

After the avalanche has stopped, you should immediately search the avalanche surface for clothing or
Search equipment. As a result, many a partially buried person has been successfully born.
With avalanche transceivers and avalanche probes or avalanche search dogs, the exact location can
are recorded. After that, the first-aid measures begin, whereby the patient with hypothermia
must be recovered carefully, otherwise supercooled, oxygen-poor blood will get into the inner
Organs flows, which can result in death.
