But for real, that video is amazing

That's a Hollywood special effect just like the moon landing.

It seems odd that we have facilities like this that can't take a lighting strike without exploding.
Believe it or not, everything worked like it was supposed to. All the liquid was contained in the tank

It should have been, and perhaps it was. I've worked in plants for 30+ years and structures, tanks, equipment, everything is well grounded in plants. Maybe something went wrong or wasn't grounded properly. OSHA will be on site and figure it out.

Why was that tank not grounded?

How was that much oxygen present in a nitrogen blanketed Naptha tank to allow ignition? It was above the LEL and below what should have been a UEL from all that naptha vapor psi and nitrogen inert blanket? Something failed to operate properly in the vent system for a long period of time to cause that explosive mixture of naptha vapor and oxygen that only needed an ignition source. Heck static could have created that explosion. No grounding grid is ever gonna stop an explosion if the atmosphere for it is primed up like this.

I am guessing the roof is supposed to peel back like that to keep the sides from collapsing? Let the flame and explosion go up?

I would think that the vapor space should’ve been blanketed to keep it out of an explosive range. Normal system would be a natural gas blanket to keep it above the higher explosive range and a vapor recovery system to manage the pressure.

Food processing plants like to catch fire alot, too.

Yeah, the best comment from the video was:

For those not familiar with these tanks. The failure here is that there was oxygen in the tank.
It is typical for these tanks to have 100% natural gas (not flammable without air) or 100% nitrogen in the top of the tank.
Without this these tanks would be exploding left and right due to static electricity that builds up due to flowing fluids.

I need that video for work. Does anyone know how to download a copy?

It douubtlessly was...and grounded properly. It looks like it worked as designed. Nothing is 100% effective against discharge...a pine 2x4 will make a helluva conductor if you apply enough pressure. the way the roof material expands and peels back looks like there is intentionally some form of gas between the roof and anything in the tank which is meant to burn off without involving the liquid. Don't know that for certain but it certainly appears to be somewhat controlled...other wise the entire tank would have exploded, most likely.
