CRG Highline incident and consequences on webbing lifetime recommendations<\/b><\/h1>\nOn April 20th, 2024, there was a mainline and backup failure at Cosumnes River Gorge (CRG), California, United States of America. The failure occurred during a spontaneous tandem session, with the main snapping during a leash fall and the backup failing as it engaged. Both highliners fell but had only minor injuries given the circumstances.<\/span><\/h2>\n<\/div><\/div><\/div><\/div>Up until now the lifetime recommendations for non-PES (Polyester) and non-PA (Polyamid\/Nylon) webbings were summarized as “high-tech\/low stretch” webbings in our highline gear standards. Due to the CRG incident the ISA Safety Commission decided to specifiy the materials more clearly and revise the lifetime recommendations.<\/span><\/p>\n<\/div><\/div><\/div><\/div>Read the full CRG incident report<\/span><\/a><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>[give_form id=\"8450\"]<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>New lifetime recommendations for highline webbing:<\/span><\/h2>\n<\/div>We created a more specific UHMWPE (=Dyneema\/Spectra) webbing category from which our database does not (yet) allow to make precise recommendations for lifetime, due to a small amount of datapoints that fit the category.
