Due to the risk of unintentional opening of the D-ring attachment point, which could result in a life-threatening situation, Petzl has asked to cease use of the Astro and Canyon Guide harnesses and immediately carry out a prescribed inspection.
A detailed description of the affected harnesses, including model and serial numbers as well as the inspection process, can be found here.
According to Petzl, the defect is due to a poor machining process of the metal D-ring. While the defect presents a risk of death due to strangulation or falling from a height, the company
noted that no injuries have been reported to date.
