I know we try to share on here so everyone can learn and see things that can and do go wrong, and go right. This climber probably has 1000s of hours in gear and something like this happens once in 1000s+ of hrs. or more. Combined, all the recreational climbers on this site probably don't log anywhere close to the hours of a pro climber, so it's imperative we continue to share our close calls to help others to see in comparison of what may work, and what may work safely. As this fella stated, it may have been something he could have caught in a gear inspection. Gear inspection is something we should all do thoroughly before we climb every time. I know I got a little weak in the knees when I saw his clip hanging.
I was taking out a giant White pine in a friends side yard years ago. I was limbing it to the top so I could pop the top off and chunk it down. I got moving in a rhythm taking the limbs off. I had to unhook for some reason and as I got my wirecore lanyard clipped back on I started to lean back to put the weight back onto the lanyard, Before I got my full weight back on it the hairs raised in a chill on the back of my neck, I immediately stood back up on the spikes to take weight off the lanyard. As I looked down I saw that I had actually clipped into a non load rated accessory loop. I didn't feel like I was rushing but I can say I probably wasn't as deliberate as I should have been, and I don't know if I leaned my full weight into that loop if it would have failed, but at 80+ feet I'm glad I didn't find out.
We know that the climbing portion of our sport is the most dangerous part of it. It makes me nervous to see some concerned with how fast they can get up the tree, or how light they can get the climbing method. Be deliberate, and be safe, and if you have any doubts about what your doing, or a new thing your wanting to try, or a piece of gear you want to try, throw it out here and lets discuss it, especially if your not a professional climber.
