• Alaskans are highly

active in the outdoors

• Many new to Alaska

or to this area

• Refresher on winter

backcountry safety
and what to do in

event of an
accident/emergency

Overview

• Review Winter Hazards:

– Hypothermia
– Frostbite
– Avalanche
– Thin ice

• Trip Planning/Essential Equipment
• What to do in a backcountry emergency

i i i

• How to initiate/request a rescue
• What to expect during a rescue response

Backcountry Hazards--Winter

• Winter backcountry travel requires MORE

SKILLS and MORE EQUIPMENT

• Educate yourself about the hazards

• Get additional training

• Know the weather and anticipate conditions

expected

Hypothermia Prevention

•

Carry sufficient food, clothing, stove/pot

•

Stay well hydrated and eat often

•

Minimize over-exertion and sweating

e ove e e t o a d sweat g

•

Dress in layers, USE SYNTHETIC CLOTHING

•

Know how to build a snow shelter(s)

•

Learn winter survival techniques (take a class or
learn from others)

learn from others)

•

Avoid alcohol, nicotine, caffeine—affect circulation

(B) Frostbite:

3 Stages

(B) Frostbite: 3 Stages

Frostnip

• freezing of the top layers of skin

tissue

• involves only a small area, such as

a cheek, earlobe, fingers or toes.

Signs:

• Firm white cold areas show up on

• Firm, white, cold areas show up on

the face, ears or extremities.
Sometimes 1-3 days later, peeling
and blistering occurs.
O

• Occasionally, the person remains

very sensitive to cold afterwards.

Treatment:

• Re- warming the affected part with

skin to skin contact, do not “rub”

Superficial frostbite

• The skin feels numb,

waxy and frozen.

t l f

• Ice crystals form in

the skin cells and the
rest of the skin

rest of the skin
remains flexible.

• Blistering may occur,

Blistering may occur,
particularly after re-
warming

Full thickness frostbite (3

stage)

Full-thickness frostbite (3

stage)

• blood vessels,

muscles, tendons,
nerves and bone may

nerves and bone may
be frozen.

• Permanent damage,

blood clots and
gangrene.

• Serious infection and

loss of limbs
frequently occurs

Frostbite Treatment

Partial or full thickness (frozen)

A: Re warming should be initiated as soon as possible

A: Re-warming should be initiated as soon as possible,

but only if can keep from re-freezing Warm water
bath at 99-104 °F. Do not massage or use radiant
heat

heat.

B: If the frozen tissue cannot be protected from

refreezing, or if re-warming not practical or will

delay evacuation, protect wound with sterile gauze
and allow to remain frozen.

C: Protect blisters and damaged tissue and avoid

constriction

D: Protect from re-freezing.
E: Pain management
F: Get person to medical care

Preventing Frostbite

• Avoid tight-fitting clothing, including footwear,

f l hi

• Wear several layers of clothing when in

extremely cold conditions since the air pockets
between the layers will help to retain warmth.

• Do not use of alcohol, caffeine and nicotine

• Stay hydrated and keep calorie intake up.

• Shield/cover face and other body parts from

Backcountry Hazards--Winter

(C) Avalanches

– Increasingly catching winter recreationists

t h

who are unaware of or underestimate hazard

– Take classes, educate yourself BEFORE

Take classes, educate yourself BEFORE
venturing into mountain terrain in winter

– Carry beacon, probe, shovel & practice using

them often

• Be Prepared—mentally

(educate yourself, take an

avalanche class)

• Be Prepared—physically

(go with right people,

right equipment)

• Practice Rescue Regularly—

get

your friends to

do so as well

Travel as though rescue doesn t work,

but practice it as though it does.”

Trip Planning

(A) Leave a trip plan with family

member or friend

–

Where

you are going

–

When

you expect to be back

–

Route

of travel

–

Amount

of gear taken + colors

–

• Contact AK State

Troopers!!

• 911

When reporting an emergency

• Make sure “backcountry emergency”

• Give name and location (be specific)

• Number of persons in the party

• Describe nature of emergency/medical condition

• Describe nature of terrain/situation

• Remain in contact with rescuers

• Make yourself as visible as possible

What to Expect

• Response highly

dependent

Will t k

• Will take some time

for rescuers to arrive

• Often will arrive via

helicopter

• Rescuers will approach

cautiously

When to request a rescue?

(B) If A family member, friend, co-worker is

overdue from a backcountry trip:

Was there a trip plan?

Wh t did it

d ti

What did it say about route, destination, return

day/time?

Do NOT wait to initiate rescue unless trip plan

indicates potential for being late/overdue.

Call 911 or AK State Troopers

to notify of

Call 911 or AK State Troopers

to notify of

backcountry emergency and need for rescue—

make clear that this is a backcountry

emergency not a missing person!

7 Lessons for Survival

• Perceive and believe

• Stay calm

• Think analyze plan

Think, analyze, plan

• Take correct, decisive action

B li

ill

• Believe you will succeed

• Do whatever is necessary

• Never give up
