The people who built the tower don’t seem to have made much accommodation for the people who would someday have to climb up there. There are ladders, but only for some of the climb, and at those points there are no closed-loop points to clip the safety line to.
The voice-over says that reattaching the safety line every few feet is tiring. The problem is in the design. They could build a guideway for the safety line, with ratchets along the way. You could pull the line up as you climb, but if you fell it would catch on the ratchet and stop you in a few feet.
I don’t understand at all why there is no permanent safety line going the full height that allows the worker to clip on and remain clipped on?
I’m on a jobsite right now with a 30 meter tall stair tower, and climbing that is freak’n exhausting! I couldn’t imagine doing just 30 meters of ladder!
We follow the rule where you are always tied off when working at height, no matter what. That means wearing a full harness with two hooks, so that one of the hooks is always attached to a safety line or handrail.
Thing is, even if the dude was clipped on and had a nasty fall, how the hell would anyone rescue him? If he was at the very top I could see a helicopter winching him up like a haggis, but further down the tower - they could send people up, but if he were knocked out or struck by lightning or something, how would they get him off the ladder?
High angle rescue taken a few classes but never had to actually do it for real.
in a nushell you climb up, with a bunch of rope and some pulleys.
Tie yourself off, find a way to rig a pulley, hook rope into climbers harness, and lower him down to a level where they can pull him into the elevator.
There’s also the problem of getting caught in the guy wires or hitting the tower on the way down. I’m sure BASE jumpers push off the tower in the correct position to miss them, and so that the wind won’t carry them back into the wires. If someone just fell at random, there’s lots of things that can go wrong even with a parachute.
Firefighters do that all the time even if only in drill, fire ladders are much sturdier than the pegs those guys climb and the side rails on the ladder offer some additional safety/place to grab if you slip.
