There are historical precedents of avalanches tragic on the slopes of the Italian alpine arch?
The most serious case dates back to 1991, when 12 skiers (including a girl of just 2 years old) died on the track at the Pavillon (Courmayeur) in an avalanche triggered by the collapse of a glacier on Mont Blanc.

The avalanche bulletin - issued in the main mountain resorts - indicate, however, the risk of detachment with a scale from 1 to 5: "But this is a bulletin in the conditions of the snowpack and the virgin. In the ski areas there are very special circumstances, which must be evaluated each day by the managers of the areas," explains Gheser.

it Is a backpack and airbag (for floating on the snow), a unit of research scattered (Artva), probe and shovel to search the snow. The kit should be used for those come from the paths beaten. But for obvious reasons it is little used by those who ski in the track.
What to do in case of an avalanche?
you Should try to exit sideways from the trajectory of the avalanche or still try to remain on the surface. It is important to get rid of skis and poles because they increase the risk of getting trapped. Those who remain under the snow has to create with the arms, a cavity in front of the face to be able to breathe.
