HYPOTHERMIA FACTS
• Body thermal conductivity in water is 26 times faster than when exposed to air. If you have a life raft, board as soon as possible.
• 50 degree water equals 15 minutes before incapacity and/or unconsciousness with life jacket on. • 50 degree water equals 9 minutes before incapacity and/or unconsciousness without a life jacket
