Members: Falling on Teeth

Technicians regularly use toothed-cam ascenders such as the Petzl Croll.  For climbing ropes, the chest-mounted Croll is normally used in conjunction with another handled ascender and foot loop.  Technicians are generally taught to ensure they are also attached to this second ascender via a lanyard.  Recently a RopeLab member asked about the importance of this second connection and the realistic consequences of falling while ascending.
