I just found this video - https://www.youtube.com/watch?v=KTXUOWMCn_8

I now know why we use the 1000 second rule - to put out the fire

HI All

Great video and thanks for sharing it. Two questions:

1) Can anyone interpret what the workers are saying in english?

2) I do no believe that the facehields they are wearing are arc rated? They appear clear for cutting or grinding

Like so many, I've seen a lot of arc flash videos but this one is truly amazing - thanks for sharing. It looks like the guy was out of there in under 1 second so I guess the 2 second cut off held true. Throwing snow was a nice touch!

Last exchange before the arc was ignited:

- Execute!
- Executing...
[boom]

I might be missing but from the conversation it appears that they've been trying to operate non-load break disconnect switch on a live bus.
