650 to 750V DC. Admittedly more voltage, but we have 240V here
That's like comparing a lighter to a blowtorch.
I just skimmed that report, and that was my thought, too; in that case, it wasn't the voltage, but the current supply - I didn't read the report far enough to know if they mentioned how many amps (likely hundreds, possibly thousands?) the system could supply, but I sincerely doubt that -anything- would've helped. That kind of electrical contact, regardless of where or how it happens almost always results in "instant death" or at best, a very long convalescent period (from which you are never the same again).
When I was speaking of the "one hand rule", I was meaning more in the case of electronics that you would likely find on a workbench.
