Bro they gave us John's whole back story before showing us how he died, definitely top 3 saddest deaths in anime

[charlessmith]

In this arc-flash simulation, the electrician died for three reasons....
1. He failed to make sure that the spanner wrench would never, ever drop into the conductor, usually by using wrist harness bungees that will keep the spanner in place.
2. Sadly, he failed to make redundant or backup confirmations that the equipment was de-energized for sure, and my guess is that he failed to find a second or backup disconnect to really de-energize anything at all. The mantra - everything needs to be de-energized before doing anything! Not just a portion!
3. He also failed to wear the proper arc flash protection. His electrical outfit had no chance against the calcium-produced arc-flash heat of the accident. He should have worn PPE designed for arc flashes that had a rating of 40 or more.

My co worker just got damaged by arc flash and it is unbelievably horrific, may this won’t happen to any body else. If you read this your prayers is apreciated

[abdulazizhawsah]

Respect, for your education technique 👍🏾 I love it.

[kabanguwashiye]

very touching, PPE is very important and will always save the life of people.

[dannymcdermott]

important message, but creepy characters.

[BXMATTER]

The narrators tone of voice and the style of the animation makes this tragicomical.
"John has a boss."
"John has a family."
"John did an oopsie."
"Now John is dead. His family cries around his deathbed. Sad. That John is now dead."

Quite informative thank you, I wish to get more video that you made before and you going to do in future.

I just came from a video where a switchgear can flashed over even though it was closed and no-one was there working on it. In that case, there was no tool to be dropped onto live conductors. Any idea what may cause an arc flash in such an incident?

[laojiaweiwilliam]

May I know why did the arc flash still happened even though the power was shutdown as shown in the video?

[Roberto-cggr]

What is the cal/cm2 ratings of metal sheets based on material and thickness?

[Roberto-cggr]

What is the arc flash rating of metal sheets used in panelboards and switchgears based on material used and thickness?

[dangerousmythbuster]

First thought, Jeff looks like Odo from Star Trek: DS9.

[vonshango]

0:36 electrician kills power to the panel he's working on and tests to verify, but drops a wrench into an unprotected live panel which shorts that circuit.

[ja_adam_]

Can you get arc flash by switching 230v/400v MCCBs or other switchgear

[RizwanKhan_]

Why didn't the breaker trip when the 2 phases shorted out?

[hinduindianguy]

If John shut the power off, then why would dropping a wrench between phases create such a horrific incident?
If there's no power, where would all that energy be coming from?

[matthewsachaullymce]

being an electrical engineer for more than 20 years.. this is the first time knowing that people work on “live” system internal gears …🤔

[HDX]

Please make more video like this, don't forget english sub.
many thanks

[ja_adam_]

Also why do you not get this on domestic consumer unit
