The Five FAQs - Avalanche

What is an avalanche? 

An avalanche is an event that occurs when a cohesive slab of snow lying upon a weaker layer of snow fractures and slides rapidly down an inclined slope such as a mountainside.


Why does it occur? 

An avalanche occurs when a layer of snow collapses and slides downhill. Avalanches are caused by a steep slope, snow cover, a weak layer in the snow cover and are triggered by either natural forces, such as precipitation, wind drifting snow, rapid temperature changes or human activity.


What are the signs of an avalanche? 

Avalanches mostly occur on steep slopes - between 25 and 45 degrees, conv
ex slopes (spoon-shaped). Loose, underlying snow is more dangerous than when compact and new snow is particularly dangerous. Rapid snow settlement is a good sign as loose, dry snow slides more easily. Low temperatures increase the duration of snow instability, while a sudden temperature increase can cause wet snow slides.


How to stay prepared? 

Keep track of weather before heading for snow-capped mountains. Stay indoors and suspend all outdoor plans once an official warning is issued, avoid steep slopes and keep an evacuation plan ready. During a low danger avalanche warning, move on slopes carefully and mark your tracking path using a piece of cloth, stick etc.


If stuck, how to stay safe during an avalanche? 

Try to stay on the surface or get away to the sides and hold on to something sturdy. Make breathing space by creating an air pocket using one hand and knock the surface regularly to attract rescuers.

  1. Mookty is an ideation with helium filled air-pillows fixed with a fish line till the burial of one who may be holding an electric whistle to get the dog earliest for rescue.
    Avalanche AirBags are dual pattern overall extreme winter wear where unmixed Vinegar(kept warm by body temperature from inside) and Baking soda are kept separated only to be mixed in case of an avalanche catastrophe by a switch . The trapped profusion of Carbon Di Oxide will prevent asphyxiation of trapped troops . Moreover the escaping gases can also cause release of odour and ink for rescuers to determine the location of the snow burial . An embedded bubble paper vest can be also used to duplicate such packing of troops so that the crush and the resulting asphyxiation is avoided . 80% of death in Avalanches is resulted from asphyxiation .
