Facts
- Frostbite can occur in minutes when the temperature is below 20 degrees Fahrenheit and winds are over 20 miles per hour.
- Some cases result in permanent damage causing chronic pain, sensitivity to cold, and numbness. In extreme cases amputation may be necessary.
- Because the amount of tissue destruction is proportional to the time it remains frozen, rapid transport to a hospital is very important
Causes of Injury
- Freezing of body parts exposed to:
- cold temperature
- moisture
- wind
Planning / Packing Guide
- Layers of clothing:
- First layer of silk or other breathable synthetic long underwear.
- Second loose layer traps insulating air covering arms, wrists, and neck.
- Third layer to absorb moisture; should be easy to remove to avoid overheating.
- Last outer layer will face the elements and act as a shell against rain, cold, or sun. It should breathe or have vents. Pants with zip-off legs in water-resistant fabrics are ideal for all temperatures.
- Wool cap
- Insulated waterproof gloves
- Socks:
- Thin layer of socks against the skin
- Thick layer of wool or synthetic socks

First Aid
- Seek medical attention as soon as possible.
- Watch for signs of Hypothermia.
Saving a life is more important than preserving a limb. - Move to a warm area to prevent further skin damage.
- Remove all wet clothing and constrictive jewelry.
- Elevate the affected body part.
- Apply a dry, sterile bandage or cotton between any involved fingers or toes.
- Avoid walking on frostbitten feet.
- Avoid a gradual thaw either in the field or in the transport vehicle.
- Never rewarm an affected area if there is any chance it may freeze again.
The thaw-refreeze cycle can cause serious damage. - Do not rub the frozen area.
