Cold Weather Dangers – Frostbite & Hypothermia


wintertime

We at ivalueSafety.com want to share how to prevent, identify and treat Cold Weather Dangers of Frostbite & Hypothermia per the following:

Cold weather can be dangerous for anyone who enjoys outdoor winter sports, and people who work outdoors during winter must be particularly mindful of the risks.   .

Before venturing outside in winter, be sure to:

    • Check the temperature and limit your time outdoors if it’s very cold, wet or windy
    • Bundle up in several layers of loose clothing
    • Wear mittens rather than gloves
    • Cover your ears with a warm hat
    • Wear socks that will keep your feet warm and dry

Frostbite

Even skin that is protected can be subject to frostbite. It’s the most common injury resulting from exposure to severe cold, and it usually occurs on fingers, toes, nose, ears, cheeks and chin. If caught early, it is possible to prevent permanent damage. If not, frostbite can lead to amputation.

Superficial frostbite affects the skin surface, while the underlying tissue remains soft. The skin appears white, waxy or grayish-yellow and is cold and numb.

If the condition is allowed to progress to deep frostbite, all layers of the skin are affected and the outcome likely will be more serious. The skin will become completely numb, blisters may form and eventually the skin tissue dies and turns black.

If you suspect frostbite:

    • Get indoors immediately
    • Seek medical attention
    • Remove constrictive clothing and jewelry that could impair circulation
    • Place dry, sterile gauze between toes and fingers to absorb moisture and keep them from sticking together
    • Elevate the affected area to reduce pain and swelling
    • For superficial frostbite, you may also place the affected area in water that is 100 to 105 degrees until the tissue softens

 

Hypothermia

Hypothermia occurs when the body’s temperature drops below 95 degrees. Severe shivering, one of the first signs of hypothermia, is beneficial in keeping the body warm. But as hypothermia progresses, shivering gives way to drowsiness or exhaustion, confusion, shallow breathing, irregular heartbeat, slurred speech, loss of coordination and, eventually, unconsciousness and even death.

In one of the most bizarre symptoms of hypothermia, “paradoxical undressing,” a person actually undresses instead of bundling up. Researchers believe that in the final throes of hypothermia, a person may feel like he or she is overheating due to a rush of warm blood to the extremities.

So what should you do if you encounter someone suffering from hypothermia?

    • Move the victim inside and remove any wet clothing
    • Call for medical attention
    • Add blankets, pillows, towels or newspapers beneath and around the victim
    • Cover the victim’s head
    • Handle the victim gently to avoid cardiac arrest
    • Keep the victim in a horizontal position
    • If necessary, give CPR

None of these steps are a substitute for proper medical care. Be sure to seek medical attention for frostbite and hypothermia as soon as possible.
