Petzl has published a statement addressing special use of the Petzl Shunt as a back-up device for industrial rope access. For any users of the Petzl Shunt as a self-belay device such as tower rescuers, the same information applies.
For Roco Tower Work and Rescue students who were taught the use of the Shunt as a self-belay device and have not attended Roco’s Tower Work and Rescue refresher training in the past two years, please read this information. For recent initial and refresher students of Roco’s Tower Work and Rescue class, students were taught to use the Petzl ASAP as their self-belay device. Roco still encourages all prior Roco Tower students to review the Petzl statement to become familiar with their concerns regarding the use of the Shunt as a back-up device.
