To stay on top is everything 
     
Only a lot of luck will save some of the victim’s lives...

An avalanche consists of different particles of snow. Those particles move underneath each body and push it to the surface by rotating until the avalanche slows down. This fact and the change of direction of the avalanche are the reason why approximately half of all avalanche victims end up on top of the avalanche.
... others die in the avalanche.

A completely different scenario exists for those who do not end up on the surface of the avalanche. Once the avalanche slows down, rotation and lifting abilities also slow down. The victim cannot reach the surface anymore due to the higher density and lesser volume. In most cases this burial is deadly.
With the ABS you have 150 liters more volume ...

Once activated, the ABS equalizes the volume and density of the victim relative to the surrounding snow by working on the principle of "inverse particles" .

...and you are ontop within 2 seconds.

As with a life vest in the water, the victims swims on the surface of the avalanche. The added volume of 150 liters has been calculated to be needed for cold, dry and loose snow. If the snow is denser, wetter and heavier less volume is needed. The statistics show that all victims carried down by a moving avalanche stayed on top and survived the incident (see the statistics) .

The ABS has proven its worth in many tests already. An increasing number of avalanche victims owe their lives to the use of the AB. See the hard facts for more details.

Quick Facts:
Approximately 95% of all avalanches involving skiers and snowboarders are triggered by themselves. Usually they are slab or flow avalanches. 50% of all avalanche victims survive the avalanche release not buried, or with at least the head showing allowing them to breath. Only about 5% suffer from deadly injuries due to falling. 95 % survive.
Ilustration of the risk getting burried by an avalanche The remaining 50% are completely buried once the avalanche comes to a halt, or at least the head and chest are submerged in the snow. Approximately 20 % suffer from fatal injuries due to the fall. Out of the 80% which are still alive three quarters (75%) have blocked airways due to snow in their mouth and / or experience such strong snow pressure on their chest that their breathing is severely restricted.
Experience shows that these avalanche victims only stay alive for a few minutes. The assumed bench mark of 15 minutes is extremely optimistic.
One quarter of the completely buried victims have clear airways, some can even breathe through an opening to the outside. Only these victims have a good chance to survive.

This happens:
not buried buried
not visible on the surface

survivors
not buried buried
95% survive because they are not burried 5 % die from
the fall		 80% die due to late rescue Out of the 66% that die, 20% die due to injuries incurred during the fall and approx. 80% die due to a late rescue!
