Very good point!
EPA must have been in charge there.
You're looking at video from 1.5 to 2 miles away. Those arcs are the size of tractor trailers, travelling at a pretty significant speed.
Any news agency get updates on how the nuclear plant there is doing? It appears to be in the direction of the explosions and would be much closer than any video I've been able to find.
Wow! The video looks legit, that’s crazy!
Or every piece of equipment in the Tianjin Fire Department
Now reported as Petrol (gasoline) storage station.

Probably include some fire trucks.

Gasoline will burn, but to explode like that?
You’d need to deploy it like a fuel air bomb.
Wouldn’t you?
Another vid, MUCH CLOSER.
You can see the shock wave coming.
I would be very surprised if this person isn’t injured.
Tianjin is also home to a watch factory of quite a size. I sure hope they are not damaged in this explosion!
(Sea-Gull and other brands, not knock-offs, for once)
BLEVE (boiling liquid expanding vapor explosion)
From the MSDS
Storage: Because of acetylene's unstable nature, it must be stored under special conditions. This is accomplished by dissolving the acetylene in liquid acetone. The liquid acetone is then stored in the acetylene cylinder, which in turn, is filled with a porous (sponge-like) cementitious material.
So if acetylene was involved, acetone likely was present.
The EPA must have been over checking the place out.
Tianjin University = Helix Nebula

bad day for pipeline/storage tank explosions near CERN collaborators
Of the video I just posted:
Slowed down the video from Tianjin, the shockwave appears to destroy the wall and sends it straight towards camera

When exposed to excess temperature, pressure, or mechanical shock, pure or less than pure acetylene gas can undergo a violent, explosive decomposition reaction. Additionally, if this reaction, or an ignition of acetylene occurs within the torch base or supply hose, it can propagate back into the storage cylinder causing it to explode violently. (snip) Acetylene has a very wide range of flammability. The lower flammable limit (LFL) is typically listed as 2.5% and the upper flammable limit (UFL) is listed as 81%. Although acetylene will not undergo combustion at concentrations above the UFL, it can undergo an explosive decomposition reaction, even at concentrations of 100%.
One cylinder goes, damages others, and you can have a real mess.
