NJOEM's Winter Weather Awareness Week:
Wind Chill, Frostbite and Hypothermia
(TRENTON, NJ) – Colonel Rick Fuentes, Superintendent of New Jersey
State Police and Director of the New Jersey Office of Emergency Management,
is celebrating Winter Weather Awareness Week beginning today and ending
Friday.
Each day will bring a new message for family preparedness during the
winter months.
Today's message: Wind Chill, Frostbite and Hypothermia.
What is Wind Chill?
Extreme cold can remain even after a winter storm has passed. Prolonged
exposure can cause life-threatening frostbite or hypothermia. Infants
and the elderly are the most susceptible, but everyone should take basic
precautions.
Beyond the actual temperature, wind chill demonstrates the way wind
and cold combine to affect exposed skin. As the wind speed increases,
heat leaches away from the body at an increased rate, driving down the
body temperature. The National Weather Service Wind Chill Chart at http://www.weather.gov/om/windchill/index.shtml
indicates how quickly the wind and cold can cause frostbite.
The following information on hypothermia and frostbite is adapted from
information by the Centers for Disease Control and Prevention (CDC).

What is Hypothermia?
Hypothermia, or abnormally low body temperature, results when the body
starts losing heat faster than it can be produced. Hypothermia can affect
the brain, making it difficult for the victim to think clearly or move
well, or even to know they are in danger.
Hypothermia symptoms include uncontrolled shivering, memory loss, disorientation,
and drowsiness. Warning signs in infants include bright red, cold skin
and very low energy. If you notice these signs, take the person's temperature.
If below 95 degrees Fahrenheit, seek medical help immediately.
If medical care is not available:
- Get the person into a warm room or shelter.
- Remove any wet clothing.
- Warm the center of the body first, including chest, head, neck and
groin, using an electric blanket if available. Or use skin-to-skin
contact under loose, dry layers of blankets, clothing, towels or sheets.
- Warm beverages can help increase the body temperature, but DO NOT
give alcoholic beverages. DO NOT try to give beverages to an unconscious
person.
- Keep the person dry and wrapped in a warm blanket, including head
and neck.
- Individuals with severe hypothermia may be unconscious and may not
seem to have a pulse or be breathing. CPR should be provided until
the person is being warmed, until the person responds or medical help
becomes available. In some cases, hypothermia victims who appear to
be dead can be successfully resuscitated.
What is Frostbite?
Frostbite is damage to body tissue caused by extreme cold.
Symptoms include numbness and a pale color in extremities, such as
fingers, toes, earlobes or the nose. Skin may feel unusually firm or
waxy. If you detect these symptoms, get medical help immediately and
slowly re-warm the affected areas.
If medical care is not available:
- Get into a warm room as quickly as possible.
- NEVER rub or massage frostbitten skin, especially not with snow.
This can cause more damage.
- Unless absolutely necessary, NEVER walk on frostbitten feet or toes.
This can cause more damage.
- Warm affected areas with warm, NOT HOT, water. Or use body heat
- for example, placing hands under armpits.
- DO NOT use a heating pad, heat lamp or the heat of a stove, fireplace
or radiator for warming. Affected areas are numb and can be easily
burned.
Family Preparedness
Children and adults should follow these winter safety tips:
- During a snowstorm, stay inside.
- When you go out after a storm, dress in layers. Many layers of thin
clothing are better than a single layer of thick clothing. Outer garments
should be tightly woven, water repellant and hooded.
- Most body heat is lost through the top of the head, so always wear
a hat and earmuffs.
- Mittens are better than gloves, because fingers maintain more warmth
when they touch each other.
- A scarf worn over your mouth will protect your lungs from extreme
cold.
- Come inside often for warm-up breaks.
- When working outdoors, slow down and take frequent breaks to avoid
overexertion. Cold weather puts an additional strain on the heart.
If you feel chest pain, stop and seek help immediately.
- If you shiver uncontrollably or get very tired, or if your nose,
fingers, toes or earlobes start to feel numb or turn pale, come inside
right away and seek medical help. These are warning signs of hypothermia
and frostbite, as described above.
Family Preparedness
For New Jersey residents, the basics of preparedness for nor'easters
and winter flooding are virtually the same as preparedness for all hazards,
natural or manmade:
- FIRST: Arm yourself and your family members with an Emergency
Supply Kit and an Emergency Action Plan.
- Your Emergency Supply Kit should include a blanket, a battery-powered
radio, a first aid kit, one week's prescription medications, personal
toiletries, infant care items, three days' worth of non-perishable
food and water (one gallon of water per person per day), a can opener,
and cash or travelers checks. For more, visit the American Red Cross
website: www.redcross.org/disaster/safety/fds-all.pdf.
- Your Emergency Action Plan should include an out-of-town
contact your family members will call or email to check on each
other, a predetermined meeting place away from your home, and specific
plans for individuals with special needs or disabilities. For more,
visit the American Red Cross website: www.redcross.org/static/file_cont36_lang0_23.pdf.
- NEXT: Pay attention to weather media and your local radio
or television stations for weather updates and for official
instructions from Public Safety Officials.
- If you live in an area prone to flooding: Know your evacuation
route. You can find maps of New Jersey's coastal evacuation routes
at the New Jersey Office of Emergency Management's website, www.state.nj.us/njoem.
In all areas, call local Emergency Management officials or Police
Department for details on your evacuation plan.
