This is a small Video so you when you open it up right click on the Video Area and use the Zoom option and put it at 200% it will give a bigger picture.

This video will show you how dangerous Electricity is... - http://www.brainfiller.com/ArcFlashwhilerackingabreaker.wmv

Page doesn't load for me,Woodyblade.

Worked for me and OUCH? flamethrower.gif

Sorry DSTM don't know if anyone else has had problems since your the only one replying outside the UK, it might be limited to the UK viewers? not sure why it wouldn't work I just copied the link from a forwarded email I got.

Maybe try it again?

If it doesn't work a second time not sure how to resolve it without more people outside the UK replying to say either it works or doesn't.

I'll add a bit of info later, I can ask my Dad (He's an Electrician who has worked on Cabinets very similar to those on the Railways, nearly 30 years now) what actually went wrong for that bloke on the video, the little I know about those Cabinets is they supply about 11,000 volts I think.

When I use the link it wants to download into Media Player.
Have you tried right clicking on the link and selecting "Save target as..." or "Save link as..."
Once it's saved to your hard drive try to open it with Media Player.
DSTM
Thanks USASMA.That worked a treat. thumbup2.gif
Saved, and played with Media Player.

I think I know why it worked for the rest of us and not DSTM, I suspect that like me Emu and Usasma use Firefox? I have the Windows Media Player Plugin installed with my Firefox Browser so when I opened the link it opened and worked as normal, I think DSTM has mentioned before he uses Opera? Not sure if that has a similar Plugin since I don't use Opera.

Although I have just checked if it loads in IE and it does by loading another IE Window for a second and then opening up Windows Media Player.

Anyway as I said I'd add more information about what actually happens, can't be sure since it doesn't show what they do with the cabinet before but he is resetting the circuit breaker (Pretty much says it in the title of the Video) so they must have not done something wrong some where for him to get electrocuted.

My security levels are set to prompt me whenever anything tries to run on my system(s). That way I know if there's something funny going on (I had this happen once with WMP when surfing on the bad side of the tracks).

Ahh that must of hurt. Did the guy die?

I think because the potential voltage is 11,000 volts i.e. the difference between the Live wire and Neutral wire, it would be pretty much Game Over for that bloke, Unluckily.

Looks like he was racking the breaker in(reconnecting to the power bus). Since there are interlocks to prevent you from racking a breaker that is closed, I would guess that there was still a grounding strap on the breaker when he racked it into a live bus. Really bad thing to do.
I was working at a plant that racked a breaker in and closed it onto a grounded bus,the breaker blew itself back out of the panel. Lucky that time nobody close to breaker.

worked for me in "real Player"....I'm in US

Holy Expletive that was quite a spark

This is sick if this is in fact a video of death, it should be removed. I don't need to see video of people killing themselves to know electricity kills.

Inappropriate for this site. There are other sites for sick videos and photos. mad.gif

I'm sorry if you don't like the Video clubhouse, It's been up since the end of February as you can see and there have been no complaints about it.

The thing is (And I should have said this before) it is inconclusive as to whether he was hit or not, I think he might have been hit be it by an explosion maybe electricity, for all we know he could have just had a slight tickling voltage 1 or 2 volts maybe (I think Humans can survive that for a short period?), electricity might not have hit him, to me it looks pretty much like an explosion in the cabinet of some sort, gfroggy in his reply above (13th March) refers to the breaker blowing out of the panel so I would think that is associated with an explosion, wouldn't you agree?.

EDIT: Yep I might have said something earlier thinking he might have had it, but that was before gfroggy replied to point out what may have happened.

Current kills not voltage, I think the accepted industry standard states anything up to 50vac is safe. Anyway I stand by what I've previously stated. Just surprised to see such a video in the 'fun' section of a site who's primary purpose is related to malfunctioning computers.

Perhaps given the standard this video implies I could unearth some footage of burnt and charred bodies to "show fire is dangerous."

It's neither Amperage or Voltage that kills, its the combination of the two (Resistance is a given as it is produced by your body but will very person to person and moment to moment). 12V at 2000 Amps will kill and 220V at 5A will kill.

However the video is a good warning since when working on the PSU of a PC you are dealing with a "Step-Down Converter" (The PSU drops line voltage from 110-120v to 12-1.5v depending on usage, and converts AC to DC) which is very similar to a transformer (If you've ever seen one of those go off like a 36 inch diameter bottle rocket, you know the kind of power they pack).

My Dad is an electrician been working on the Railway Electrics for nearly 30 years, He sent me a Presentation about burns from Electric which he got from some friends where he works, that isn't suitable for here the images are a bit graphic (Bit of a Sherlock statement whistling.gif) but I know how dangerous fire can be and what burns are like.

Although I never thought a PSU in a computer is similar, Never built a comp myself so don't know really know anything about the PSU, although I will eventually build a comp in the future, guess it's something else to consider.
