Emergency
blankets are widely used in mountaineering, fire fighting, rescue
and military in the world. It is simple. In fact it is an aluminum-
plastic composition film. Its weight are very light just over ten
grams. Then someone will question that how light a thing can play
what uses? Let's first take a look at the application scope and
principles of emergency blankets . Emergency blankets are mainly
used in cold areas to prevent loss of body temperature and death.
It is generally used to cover body in climbing snow mountain
under emergency situation, in rescuing after falling into the
water. Then someone may question that how to keep warm with
just a layer of composite membrane? Next we check
out the principle of keeping warm.
There are two main ways to keep warm ,one is to add
warm layer. Generally warm layer are fluffy objects which can cause
stagnant air. These stagnant air are non-conductor of heat which
can lead warm effect. Feather woolen sweater and cotton take this
way to keep warm. The second method to keep warm use the way of
heat-reflection. Using high reflecting material to draw back heat
radiation. We all know that white clothes are cooler than black,
because white reflect heat over the black, and it can reflect
sunshine back. The emergency blanket takes combination of these two
principles. The film in aluminum film is to ensure stagnant air
over the body. Its main function is that highly reflective material
can reflect body heat radiation back. The reflection efficiency is
above *0%. Then it effectively reduces the speed of body heat loss.
Since aluminum is metal, it is easily to torn, the intensity is not
high. Therefore, the main purpose of composite plastic film
is to increase the toughness and strength of emergency
blanket.
Generally emergency blanket has
length and width both in two meters in order to completely cover
the body. Also some emergency blanket are simply produced
into sleeping bags like envelopes ,Under emergency situation
you can directly put body into it .when folded up it is only half a
palm size and a few millimeters thickness only. there is no
encumbrance to carry such a thing in your bag. What kind of uses of
emergency blanket for outdoor activities? The use of climbing
snow mountains as we all know, is unnecessary to talk.
Generally we should carry one in outdoor activities. In
winter when we go out, once temperature decrease we can cover the
emergency blankets. Another method is that we can use emergency
blanket cover sleeping bag to keep comfortable sleeping. In summer,
if accidentally falling into the water, or catch a rainstorm. You
can use the emergency blankets to cover body for heat regardless of
wet because you can drop the water off the emergency blankets
easily. When it rains you can use emergency blankets for
temporary tents or temporary poncho. And regardless of winter
or summer, once emergency situation occurs, without any equipment
to live in the mountain in evening ,emergency blanket is your
sleeping bag to provide protection for life.
Such things, though insignificant, in key
conditions will play a big part. everyone possess one will provide
enough insurance. We will be more happy to share outdoor
brilliant times.
