A 54 year old piste patroller has been killed in Klosters during avalanche control work. The patroller and his colleague had loaded a launch pipe with an 8.3cm rocket. The patroller was in the process of removing 2 safety devices when the charge exploded without warning. Standing behind the device the patroller was killed by the recoil and by shrapnel from the charge. The accident follows a another incident on the 18th December at Flégère in the Haute-Savoie. In this case the charge exploded inside an avalancheur system injuring two piste patrollers. Note: See comment from Philippe Laborde from LaCroix below
