Maine Warden Service Warns: Cold Water Can Kill

Augusta – As summer nears, and the days get warmer, the Maine Warden Service is warning outdoor recreationists that the water still is very cold and that prolonged exposure in cold water can kill.

Wearing a life jacket can greatly increase a person’s survival if they unexpectedly are in the water because it can keep a person afloat.

Cold water is defined as any water with a temperature of 70° Fahrenheit or lower. Boaters should always be aware of the dangers of cold water, but particularly during the early part of the boating season when the water is colder and when there are not many other boaters around to help.

The initial shock of entering cold water can severely strain the body and it can even cause instant cardiac arrest. Survivors of cold water accidents often describe having their breath ‘knocked out’ of them upon their first impact with the water. Disorientation may also occur after cold water immersion.  In addition, immersion in cold water can quickly numb the extremities to the point of uselessness. Cold hands may be unable to fasten the straps of a life jacket, grasp a thrown rescue line, or hold onto a boat.

Proper preparation is important when boating on cold water. Follow these easy Coldwater Survival Tips:

  • Always tell someone where you are going and when you expect to return. When taking the boat out early in the season, and especially when hunting and fishing, form a group and take several boats along.
  • Dress properly for the cold. Several layers of light clothing offer better protection than a single heavy layer. Next to a diver’s wet suit, wool or polypropylene offers the best protection.
  • Always wear your life jacket when on the water. It is extremely difficult to put on a life jacket in cold water.

If you do find yourself in cold water, try not to panic. Think survival. Keep movement to a minimum and if you do have to tread water, do it slowly. This will reduce heat loss and aid retention of the air trapped inside your clothing, which can provide buoyancy and insulation. If you find yourself in swift water, float and point your toes downstream.

This summer know the dangers of cold water and prepare yourself accordingly.
