It's usually too late by the time help arrives in an avalanche scenario. If something happens you could have about 15 minutes to rescue your partner(s). You must NOT go alone. Get a course in snow rescue, find experienced people and go with them. Be alert. Always carry a basic avalanche rescue kit: a modern beacon, a probe and a shovel.
And, if you must, you could get a Cospas-Sarsat PLB in addition to your avalanche beacon.
