COLD WEATHER SAFETY
Very cold temperatures, like very hot ones, can be
hazardous to your health. Proper dress and some sensible practices can
prevent a lot of the problems associated with cold weather. In addition
knowing the symptoms of danger and how to treat them can keep problems
that do occur from becoming disasters.
GENERAL HAZARDS
The most common hazard in the cold is frostbite.
Your body doesn’t get enough heat and the body tissues freeze. Body
parts most often affected by frostbite are the nose, ears, cheeks,
fingers, and toes.
In very bad cases, frostbite can cause permanent
tissue damage and loss of movement in the affected body parts. In the
worst cases, you could become unconscious and stop breathing. You could
even die of heart failure.
The other cold hazard is hypothermia. That’s what
it’s called when you’re exposed to cold so long that your body
temperature gets dangerously low. Just like frostbite, the worst case
results are unconsciousness and death.
With both cold hazards, you’re more at risk if
you’re older, overweight, or have allergies or poor circulation. Other
factors that raise the risk are smoking, drinking, and taking
medications such as sedatives.
IDENTIFYING HAZARDS
It is very important to know the symptoms of
frostbite and hypothermia so that you can do something before it is too
late.
Frostbite can occur from being in a cold area or
from touching an object whose temperature is below freezing. In many
cases, people don’t have any idea that it’s happening. That’s why you
have to be familiar with the symptoms.
Frostbite victims usually start by feeling
uncomfortably cold, then numb. Sometimes they also get a tingling or
aching feeling or a brief pain. The recommended practice is whenever you
feel numbness, take action!
Hypothermia can also take you by surprise because
you can get it even when the temperature is above freezing. Windy
conditions, physical exhaustion, and wet clothing can all make you prone
to hypothermia.
With hypothermia, you first feel cold, then pain in
the extremities. You’ll shiver, which is how the body tries to raise the
temperature.
Other symptoms include numbness, stiffness
(especially in the neck, arms, and legs), poor coordination, drowsiness,
slow or irregular breathing and heart rate, slurred speech, cool skin,
and puffiness in the face.
As you can see, many of these symptoms are not
unusual and could mean different things. But if you’re exposed to very
cold conditions, take them seriously and take steps to relieve them.
PROTECTION AGAINST HAZARDS
The best way to deal with cold problems is to
prevent them in the first place. The most sensible approach is to limit
exposure to cold, especially if it’s windy or damp.
If you know you’re going to be in cold conditions,
don’t bathe, smoke, or drink, alcohol just before going out.
·
Dress for conditions in layers of loose, dry clothes.
The most effective mix is cotton or wool underneath, with something
waterproof on top.
·
Get dried or changed immediately if your clothes do get
wet.
·
Be sure to cover hands, feet, face, and head. A hat
is critical because you can lose up to 40 percent of your body heat if
your head isn’t covered.
·
Keep moving when you’re in the cold.
·
Take regular breaks in warm area. Go where it’s
warm any time you start to feel very cold or numb. Drink something warm,
as long as it doesn’t contain alcohol or caffeine.
SAFETY PRECAUTIONS
As you know, prevention doesn’t always work. So
it’s important to know what to do if you or someone you’re with shows
symptoms of cold problems.
The first thing to do is to get where it’s warm.
Get out of any frozen, wet, or tight clothing and into warm clothes or
blankets. Drink something warm, decaffeinated, and non-alcoholic.
For hypothermia, call 911 for medical help and keep
the person covered with blankets or something similar. Don’t use hot
baths, electric blankets, or hot water bottles. Give artificial
respiration if necessary and try to keep the person awake and dry.
For frostbite, first be aware of the don’ts:
Don’t rub the body part, or apply a heat
lamp or hot water bottle.
Don’t go near a hot stove.
Don’t break any blisters.
Don’t drink caffeine.
Do warm the frozen body part
quickly with sheets and blankets or warm (not hot) water.
Once the body part is warm, exercise it-with one
exception: Don’t walk on frostbitten feet.
It’s dangerous to underestimate the health hazards
you’re exposed to in the cold. But if you take some precautions before
you’re exposed and know what symptoms can spell trouble, you
substantially reduce your risk.
If
in any doubt, Dial 911
