Wet clothing loses all of its insulating value and transmits heat rapidly. If paralyzed persons or infants must go outside in severe weather, they should be checked frequently for signs of frostbite. If a blizzard traps you in your car . . . Stay in the vehicle. Do not attempt to walk in a blizzard.
Disorientation comes quickly in blowing and drifting snow.
Being lost in open country during a blizzard is extremely dangerous. You are more likely to be found in your car and will at least be sheltered there. Avoid overexertion and exposure. Exertions from attempting to push your car, shoveling heavy drifts, and performing other difficult chores during strong winds, blinding snow, and bitter cold of a blizzard may cause a heart attack even for persons in apparently good physical condition. Beware of carbon monoxide.
