If it happened, it wasn't preventable. If you say it was preventable, you mean that in theory, it could have been prevented by people who don't exist (front-line and management, with consciences), working processes that don't exist, using resources that don't exist, within cultures that don't exist.
They say thermal imaging could have identified the issue, does that mean that it was actually a low voltage power line, not a signal line? Do they have cameras that can see the heat from sub-mA connections?
I wonder what kind of diagnostics and logging they have for their power distribution?
"That sticker, identifying the line, kept the wire from getting a good connection in a circuit breaker – which in turn ultimately caused the first blackout. "

I don't follow how the label placement in the graphic could cause a connection issue, unless it slipped down further to interfere with the pin?
that is very much the primary event.
