Avalung (tm)
Something up the sleeve
La tecnologia può salvarci, anche dalle valanghe. Ecco come ci presenteremo nella prossima stagione di scialpinismo. Maschere a ossigeno, zaini eiettabili e molto altro ancora.
Something up the sleeve. Technology is changing more than the way we work and play, it's changing the way we dress for work and play [...] For example, Burton Snowboards of Burlington, Vt., and Motorola, Schaumburg, Ill.,have joined forces to create jackets and caps for the plugged-in winter-sports set. Motorola is credited with introducing the age of commercial wireless products, and Burton is known for its highend snowboarding equipment and apparel [...[ In Europe, snowslides kill nearly 100 people each year. Many of these fatalities are the result of suffocation, not the initial impact. Now, there's a vest that lets a trapped person breathe while completely buried by snow. Ueli Buhler, a Swiss mountain climber and crosscountry skier, wearing an Avalung, was covered with a meter of snow. After 1 hr, he was removed unharmed. Normally, someone caught in an avalanche would not survive more than 30 min. A person's breath melts the snow around the face, which then refreezes to produce a "death mask" The victim recycles the trapped air, increasing their carbon-dioxide intake before passing out from oxygen starvation. The Avalung from Black Diamond Equipment, Salt Lake City, has a pipe near the vest's collar, which must be inserted into the mouth before the person is immobilized in the snow. The tube connects to a filter at the front of the vest which draws air from the snow around the body — not just from around the nose and mouth. Exhaled carbon dioxide goes past a one-way valve and out the back of the vest [...]Continua su: Something up the sleeve
Avalanche Survival - How to Survive An Avalanche
Dal sito, americanissimo, "Secrets of survival" un altro articolo del tipo ^come sopravvivere a ... ^, a firma di tale Cliff Montgomery
If you're an outdoors person who thinks a snow avalanche is a rather semi-comic idea found only in hackneyed movies and Bugs Bunny cartoons, consider this real-life diary submission from a man hiking in Nepal: Friday, 10 November. Ang Tsering and I ask all to pack essentials in their day packs for possible bailout if this [snow] continues.Continua su: Avalanche Survival - How to Survive An Avalanche
We meet in the dining tent (resurrected). I hear Ang Tsering yell "avalanche!" and the next thing I know I'm doubled over -- pinned against the table. We all get out OK, and we're clearly blessed. The table either saved us or the avalanche had run its course.
Three of our tents were eight feet deep and five people would have been buried had they still been packing. Three tents and the dining tent were totally trashed. Most people were now without duffels, sleeping bags or day packs. We decided to get the hell out and return to dig out our tents when this stopped.
About ten minutes down the trail, the route looked suicidal. Below us in a narrow valley, a group was trying to dig a trail. In 30 minutes, we moved about 50 feet. Visibility was 200 feet, snowing in sheets, and we could hear but not see avalanches booming on all sides. This was a doomsday scenario; there we were, standing in this mess without food, clothing or sleeping bags. We went back and built a snow platform behind a safe rock.
We'll take a quick look at the necessary conditions for an avalanche, then study how you can survive such a happening - or even avoid it altogether - during your romp in the snow.

Could you survive an avalanche?
Could you survive an avalanche? Learn the science behind surviving one of Earth's deadliest natural disasters - Physical/earth: forces/weather
Oh, oh, oh! Rassicurante articolo su http://www.bnet.com/It starts with a muffled "whoomphf"--the sound of snow collapsing deep under your feet. Somewhere below the white blanket is a crack that spreads in an invisible wave through the snow all around you. Before you realize what's happening, an entire slab (thick top layer of snow separates from the ground and slides downhill. You can't escape. The snow spills into your mouth and nose, and carries you downhill like a white-water rapid at a velocity (speed in one direction) near 45 meters per second, or 100 miles per hour. You're tossed like dirty laundry. And the cloud gathers more snow as it accelerates (increases velocity)--reaching a mass or weight of up to 10,000 tons. As it finally stops, snow piles around you and solidifies like cement. Buried alive in this cold, dark place, all you can do is wait for help. Continua >>
