Tom was safely harnessed in but if he did fall he would have likely been dangling for hours before they could have gotten a rescue team up there to either pull him back up to the platform or lower him completely down to the ground.  In all my years of working in construction and engineering, I been on lots of sites that had fall arrest systems in place but no actual plans as to how to recover anyone that may have to use them.  It's not like the person that does fall but gets stopped by a life line can just easily pull themselves up again.,(reply>), @Octavia838 I'm not sure if you are aware, but there is a Tom Scott video where he does use the auto descender out of a turbine. It's called "Taking The Emergency Exit From A Wind Turbine".<br><br>This device is specifically designed so even an incapacitated person could be evacuated, but yes getting out of a fall arrest on your own in a normal circumstance is very difficult.,(reply>), I used to work on wind turbines and let me tell you, the amount of unfit service technicians was very high. Nowadays you usually don’t even have to climb the ladder but you can get up by a lift so no need to be in perfect shape. I had to do safety trainings once a year where self rescue and rescue of fallen colleagues is taught and we tried. It is extremely difficult bordering impossible to pull yourself up on your own fall arrest system depending on how far down you fell and if you are dangling in mid air. Nobody could do it in the training, not even the fittest. Now imagine being in a real situation and scared… There were rescue kits with abseiling devices in place in case of a fall to get the person safely to the ground. You can’t hang suspended for too long because of disrupted blood circulation in the legs so it’s not possible to wait around for a specialized height rescue team.,(reply>), Eventually you will find a solution. You couldn’t do that if they died,(reply>), @Tim Broski Depends on how good you are at chin ups/pull ups.,(reply>), If it takes hours he's dead either way. You can hang suspended in a harness like that for 3 minutes before you pass out.
