Cold Water Can Kill
Even after ice has melted, cold water can still present a lethal threat… and many don’t have any appreciation of this…
“Rules of 50”:
A 50-year-old person has a 50-50 chance of surviving 50 minutes in 50-degree water.
This means a typical adult has a 50% chance of surviving a 50 yard swim in 50 degree water. Very cold water takes away body heat 37 times faster than air at the same temperature….
When there is ice present, if you don’t get out of the cold water immediately by use of a ladder within only a couple of minutes… you won’t have the strength to climb out of the water if someone comes out to help you who does have a ladder.
