Harnesses save workers after crane collapse - GIF

[Jon]

While those guys got whipped around quite a bit, I actually found this GIF reassuring.

I also found something called Harness Hang Syndrome, or more formally: Suspension Trauma. If you're suspended from a harness for a long enough time (as little as 15 minutes), you'll faint. And fainting while being suspended vertically increases the risk of a certain type of cerebral hypoxia, which deprives your brain of oxygen, and can kill you.



This is addressed with something called "trauma straps". These are essentially additional straps attached to a harness, that allow a suspended worker to push against the straps with his feet, to assume a standing position.
