This is quite a video - found it while looking up information on arc flash. Id really appreciate knowing more about this as in if the guy survived and what exactly happened. To me it looked like a possible racking fault maybe racking out a breaker that was still in the closed position or trying to rack it back in while load was connected. All in all quite a scary video and one that I think that is worth seeing. If only to make a timely reminder that this is dangerous work.

RE: Video Information
Just another reason for remote racking.
RE: Video Information
Thanks for the link. I notice the guy put his hearing protection on, but no face shield for arc-flash. It's look they might be wearing FR shirt and pants - it's hard to tell.
If anyone knows the outcome, let us know.
RE: Video Information
He is cranking the crank clockwise if that sez racking IN?
Where is that other arc flash 2001 you speak of Zogzog?

Hope the guys involved were ok - looks like a big blast to be caught up in.

itsmoked, here is the one I was talking about

I did a training class 2 years ago and the OSHA inspector that investigated this accident was in my class if you want details.

RE: Video Information
One question I'm nearly always asked when I show these video clips is 'What category arc was that?', to which I usually shrug and mutter 'a bloody great big one'. Anyone care to take an educated guess on the first clip?

Click on Video library and watch the no manikin videos first, start with the 4 cal/cm2 arc flash. When we are used to dealing with higher Ei's 4cal/cm2 dosent seem like much, you will change your mind after this clip.
Then go on to watch the top 10, you can see the Ei's and specs for each one. If you think that an arc always comes straight out of the box these will change your thinking on that also. I was at this lab observing some testing last year, much more scary in person.
RE: Video Information
Thank ruggedscot, it's the best video i saw, even if you don't want to see this
Zogzog, i would like to have info on the video that you post. i heard that he was seriously injured, after the adrenaline rush, he falled into a coma, but maybe i'm confused between 2 video. And you was there for the arc flash testing... you're lucky!!!
RE: Video Information
Here are some more details on the video

There are now FR hairnets on the market.
RE: Video Information
Thanks Zogzog, pretty interresting and scary!
For the OP video, it's incredible how much the arc duration seem to be huge, maybe 3-4 seconds. I think that differential protection could help to reduce the arc duration and by the way incident energy, but it seems to be ignored by AFH analysis. Do you ever considerate a differential protection in a AFH study?
