HOW IT WORKS

your chances of complete burial, due to a
principle known as the inverse segregation
effect. Inverse segregation occurs as an
object of greater volume flows with a mass
of smaller particles. The larger mass rises to
the surface as the smaller particles continue
to flow around it. The airbag does not create
this effect if the snow is stationary. This effect
only occurs in a moving avalanche.
When triggered, the 150 litre airbag inflates
in less than five seconds. The airbag increases
your overall volume and moves you toward
the surface during the avalanche flow. A
significant percentage of avalanche fatalities
are caused by asphyxiation during burial. The
airbag improves your chances of being closer
to the surface of the snow and the highly
visible fluorescent coloured balloon allows
for quicker location and extraction once the
avalanche has stopped.
