What should you do if a companion falls through thin ice?
- Keep calm and think out a solution.
- Don't run up to the hole. You'll probably break through and then
there will be two victims.
- Use some item on shore to throw or extend to the victim to pull
them out of the water such as jumper cables or skis, or push a boat ahead of
you.
- If you can't rescue the victim immediately, call 911. It's amazing
how many people carry cellphones.
- Get medical assistance for the victim. People who are subjected to
cold water immersion but seem fine after being rescued can suffer a
potentially fatal condition called "after drop" that may occur
when cold blood that is pooled in the body's extremities starts to circulate
again as the victim starts to re-warm.
What if YOU fall in?
Try not to panic. Instead, remain calm and turn toward the direction you
came from. Place your hands and arms on the unbroken surface of the ice (here's
where ice picks would come in handy.) Work forward on the ice by kicking your
feet. If the ice breaks, maintain your position and slide forward again. Once
you are laying on the ice, don't stand. Instead, roll away from the hole. That
spreads out your weight until you are on solid ice. This sounds much easier than
it is to do in reality.
The best advice is don't put yourself into needless danger by venturing out
too soon or too late in the season.
