And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Now if you fell, and were caught by that loop, wouldn't you be hanging by both hands, but too far away from anything to climb back?
The loop is actually buckled to the harness, the person is just hold the loop to keep it from snagging. If (she?) fell, she'd be hanging from the harness and yes, pretty damn difficult to climb back up. There's also a thing called harness trauma where if you just hang there, you could also pass out and die. Oops. We have to train for that at work and plan to rescue anyone hanging from a harness after a fall within about 15 minutes. But like they say, it's not the fall that kills you, it's the sudden stop at the end.
I'm more worried about the fact that it was unbuckled to transfer across the spreader. There should be two harness loops and at no time should the wearer be nakedly free to fall.
First rule of fall arrest: don’t hit the ground. There’s a shock section incorporated into the loop that dissipates the energy of the fall by tearing the strap layers & generating a lot of heat. That slows the fall to a stop. Looks like they’re the larger flat straps that the loop buckles to. Just a solid rope/cable that won’t stretch or give a little can kill you, even in a relatively short fall. There are probably support straps in little containers on each hip. You uncase them, put your feet through loops and can basically stand up in the harness to relieve the strain on the thigh straps. Adds a little time to get rescued, but the industry standard is 15 mins if memory serves.
One of my gigs was working for a nationwide safety supply company; we carried DBI/Sala fall arrest gear. The training was pretty cool, I got dropped from the demo truck tower. It’s not fun.
you ought to try the ejection seat confidence trainer the USAF used back in the sixties and seventies. seventy feet up on rails. if you make it past forty feet your good to go. anything less and you would greet the tail planes as you went past them at more than optimal speed. teaches a guy to tuck the head back against the seat and rig the elbows in as hard as possible. our T-28s had the Yankee rocket systems to pull you out. what a ride.
y' not the only one. after my second drop (I wuz talked into both), I could find very few reasons to ever leave my Cessna 150 'til it was on the ground
From the size of the Insulator String, that may be a Million-Volt Line. Dude is "Walking on the Sun." I used to work on Helicopters that put Linemen on the Wires like this- you can find Vids of the Arcing that happens when the Lineman takes the Hot Stick and Equalizes the Helo to the Line Voltage, so he doesn't Fry like a Bug when stepping off to the Wire. The Aircraft and Crew get "Raised to the Potential" and No Damage is done to anything, as there is No Ground Path. But if a Helo Hits a Wire and gets Tangled between them, well, just watch a Bug-Zapper in your Yard....

ReplyDeleteDropping the length of that loop would kill you

ReplyDeleteI agree. Never should there be an opportunity for Murphy to show up.
DeleteI want three harnesses!
DeleteI would never have to give the loop or harness a second thought because, NOPE!
ReplyDeleteI second that NOPE!
DeleteThe boys just get sucked right up into the body cavity when I see videos like this. Don't care for heights. Nope.

DeleteHarness is too loose. Lanyards are too long.
ReplyDeleteA more robust harness, properly adjusted, shorter and twice as many lanyards for proper safe work.
Is this a power transmission line? I see insulators but no wires. Under construction?
ReplyDeleteI have no problem flying a small plane but I hate heights. Weird.

DeleteHalf of the reason for societal progress is a small subset of people that will do absolutely batshit crazy things for a paycheck.
ReplyDeleteThis is the poster boy for that subset.

Nope, nay, never, no way Jose. Guy has to be a champion tightrope walker, surprised his balls don't get in the way. Getting dizzy just watching this.
