Sigurnost na ledu za
zimske entuzijaste |
Svake godine, kako se počne lediti Boračko
jezero, znatiželjni ljudi koji žele na led imaju isto pitanje: "Je li led
siguran?" I odgovor je uvijek: "Ne, led
NIKAD nije siguran."
STRANA U RADU
Realizing that statement is usually
misunderstood as bureaucratic (and relatively evasive), Explanation that even if ice is a
30 centimeters thick in one area on a lake, it can be 2-3 centimetra thick just a few
meters away. If it were up to the people who care about ice thicknes, people would never
go on the ice. Although that is really the only way people could be totally safe, it's
probably unrealistic for anyone to expect cabin fever-stricken Boracko lake to give up one
of the few winter outdoor activities they participate in the doesn't involve tire chains
and snow shovels!
Ovdje je vodič i detalji koje treba da koriste
zimski entuzijasti da nauče i da povečaju svoje šanse ne upadanja kroz led ili pod led.
It's impossible to judge the strength of ice by its appearance,
thickness, daily temperature, or snow cover alone. Ice strength is actually dependent on
all four factors, plus water depth under the ice, the size of the water and water
chemistry, currents, and distribution of the load on the ice.
- Wait to walk out on the ice until there are
at least 10 centimetars of clear, solid ice. Thinner ice will support one person,
but since ice thickness can vary considerably, especially at the beginning and end of the
season, 10 centimetars will provide a margin of safety. Some factors that
can change ice thickness include flocks of waterfowl and schools of fish. By congregating
in a small area, fish can cause warmer water from the bottom towards the surface,
weakening or in some cases opening large holes in the ice.
- Go out with a buddy and keep a good
distance apart as you walk out. If one of you goes in the other can call for help
(it's amazing how many people carry cellular phones these days). The companion can also
attempt a rescue if one of you are carrying rope or other survival gear.
- Snowmobiles need at least 15 centimetara,
and cars and light trucks need at least 20-25 centimeters of good clear ice.
- Contact a local resort or bait shop for
information about known thin ice areas.
- Wear a life jacket. Life vests or float
coats provide excellent flotation and protection from hypothermia (loss of body
temperature). Never wear a life jacket if you are traveling in an
enclosed vehicle, however. It could hamper escape in case of a breakthrough.
- Carry a pair of homemade ice picks or even a
pair of screwdrivers tied together with a few meters of strong cord that can be used to
pull yourself up and onto the ice if you do fall in. Be sure they have wooden
handles so if you drop them in the struggle to get out of the water, they won't go
straight to the bottom!
- Avoid driving on the ice whenever possible.
Traveling in a vehicle, especially early or late in the season is simply "an accident
waiting to happen." In the many ice fatalities occurring world wide, large percent
involved a vehicle.
- Be prepared to bail out in a hurry if you
find it necessary to use a car, unbuckle your seatbelt and have a plan of action if you do
breakthrough. Some safety experts recommend driving with the window rolled down and the
doors ajar for an easy escape. Move your car frequently. Parking in one place for a long
period weakens ice. Don't park near cracks, and watch out for pressure ridges or
ice heaves.
- Don't drive across ice at night or when it
is snowing. Reduced visibility increases your chances for driving into an open or weak ice
area.
- Check at the access if there are signs that
indicate an aeration system is in operation on the lake. Aerators keep areas of
water open to provide oxygen for fish. The ice can be weakened many yards beyond
where the ice is actually open. Stay well outside the fenced areas indicated by diamond
shaped thin ice signs.
- Above all, avoid alcoholic beverages. Beer
and booze increases your chances for hypothermia and increases the likelihood that you'll
make a stupid mistake that will cost you or a companion their life. Having taken
all of these precautions, you're now going to try your luck at fishing. Walking out on the
ice, you hear a crack and break through. Suddenly you find yourself immersed up to your
neck in water so cold it takes your breath away. If you think that's no big deal, try
holding your hands in a bucket of ice water for more than a couple of minutes. If you can
do it without extreme pain, you are tougher than the average person.
Pokušajte ne paničiti. Naravno to je lakše reći
nego učiniti, ali ako imaš plan prije nego što upadneš pod led, šanse da preživiš
se mnogo veće.
