Rescue time is very short for avalanche victims. Seventy-five percent of avalanche deaths are caused by suffocation. The movement of the snow causes it to melt as it moves down slope. When it comes to rest, it rapidly refreezes and not much oxygen is left within the snow. Victims can also die by impact as the avalanche carries them down slope. The best chance of survival for avalanche victims lies with the people they are with. After 30 minutes the chance of rescue is halved.

Emergency rescue teams are made up of trained emergency workers and specially trained dogs. The emergency workers use advanced locating technology and snow probes to narrow the search area. Rescue dogs use their sense of smell to search for avalanche victims.
