Fall 2012 ABS Technology
TAKING SKI ADVENTURES TO A NEW LEVEL
Why is an avalanche airbag an advantage? § More and more skiers/snowboarders are accessing avalanche terrain each year (“Backcountry”, “Sidecountry” and “Slackcountry”) § Better equipment enables bolder exploration § Steeper slopes (30 to 45 slope angle – 38 is prime avalanche terrain!!) § Further from rescue NOT BURIED 95% survive 34% survive 5% die from Trauma 66% die 50% not buried 50% totally buried 80% from full burial 20% from trauma
Survival changes of a Completely buried Person Average time needed of professional rescue Survival chances: after 15 Minutes: ca 80% Survival changes in % after 30 Minutes: ca 40% After 45 Minuten: ca 30% After 60 Minuten: ca 25% After 90 Minuten: ca 20%
Bigger Volume => Closer to the Surface · The avalanche victim‘s volume needs to be increased to avoid foundering back into the snow without ABS with ABS
Solution - DO NOT GET BURIED!!
Why ABS? § European based company with expertise in airbag technology § Been in business since 1985 § #1 worldwide supplier of avalanche airbag packs § The North Face is FIRST GLOBAL partnership for ABS § 262 deployments – 254 survived (97% survival rate)*
HOHENESTER‘S self-experiments in the 70 s • • Hunter Josef Hohenester slid over deep couloires while carring deer on his shoulders frequently avalanches were unleashed He discovered an unexpected buoyancy effect through the additional volume of the deer he was carrying This discovery lead to the first experimental versions of floating devices
ISPO 1985: FIRST ABS ON THE MARKET • Mono Airbag System • system mounted directly to the body • optional: combination with a backpack • Weight: 8. 8 lbs
Volume adjustment · the volume of the human body needs to be increased to stay on top of an avalanche 2. 2 lbs loose avalanche snow 2. 2 lbs human body = volume of 2. 5 litres of water = volume of 1. 03 litres water 220 lbs loose avalanche snow = volume of 250 litre 220 lbs human body = volume of 103 litre difference = 147 litre
85 liter
TRIGGER • From bowden cable to pyrotechnic activation Bowden cable Pyrotechnical activation
Competition Avalanche Airbag Packs: § Mammut launching Ride R. A. S. for Winter ‘ 11/’ 12 § BCA launched Float for Winter ‘ 10/’ 11 § Other Systems: § Black Diamond Avalung Series § All Avalung versions outsell non-Avalung packs in BD line § “Hope Extender”
Fun Stats § Fatalities (by activity – ’ 99 -’ 09) § Snowmobile - 133 § Ski - 84 § Snowboard - 29 § Climb - 27 § Snowshoe - 17 § Fatalities (by TNF territory – ’ 99 -’ 09) § Rockies - 216 § West - 93 § East / NE 6 (even NY had 1) § Midwest 1 (No. Dakota) Total: 316
