Petzl ordena detener el uso del mecanismo ZIGZAG

On Friday, April 12, Petzl was informed of an accidental fall in a training center in Germany. The injured person was moving at height using a Petzl ZIGZAG mechanical Prusik. The initial observations have shown that the fall was due to a failure of the rope end attachment hole. Our investigation and further testing lead us to conclude that this failure was the result of a particular configuration of a cantilevered and off axis loaded upper carabiner.

NFPA, rescate con cuerdas,
