Do not remove any protective gear. Your snowmobile suit and helmet may keep you afloat for several minutes.
Get your head above the surface of the water, and get your breathing under control.
Swim to the edge of the solid ice you were on before you fell in. Keep your gloves on.
If you have a sharp object such as a knife or ice pick, jab it into the ice so that you can pull on it.
Kick your feet as hard as you can, and pull yourself up quickly with your forearms. Don't put all your weight on your elbows.
If the edge breaks off, move forward to the next solid edge and try again.
Crawl up onto the ice, and then crawl or roll (but don't stand—you may break through again) until you're on solid ice.
Take action immediately to prevent hypothermia.
If You Cannot Self-Rescue
If you break through ice and are unable to get yourself out of the freezing water:
Get your arms and as much of your upper body as possible out of the water.
Keep your arms still. Hopefully your clothes will freeze to the ice and keep you from falling back into the water.
Call for help by yelling or using a signaling device.
If you plan to venture out on frozen bodies of water, consider additional equipment for emergencies. Small, tethered picks designed to be carried on a person for easy access may increase your chances of survival after falling through the ice.
