Mammut is urging all climbers to immediately stop using any fixed draws as new evidence shows that the worn carabiners can cut ropes even in very short falls.
In their official notice Mammut states:
“Mammut is urgently calling for the immediate discontinuation of use and removal of permanently installed quick draws and carabiners in climbing areas. Irrespective of the manufacturer of such equipment, repeated wear can result in the formation of sharp edges capable of damaging or completely severing ropes, even in relatively small falls. Investigations by Mammut have shown that this known problem is actually far more dramatic than previously assumed and represents a very high risk for climbers.”
