Great Icebreaker video for a HAZMAT Class demonstrating the dangers of insecure high pressure cylinders in a highway accident. This was an accident that occurred in Russia. Russians have dashcams in order to provide additional evidence in court due to guard against police corruption and insurance fraud. This version contains no music.

just damn...
I'm a RRT and know a little about 02
Good point. There may have been none.
But that wasn’t the question - at least as I saw it.
The question was what happens to any fire when a huge volume of
highly compressed oxygen is added to a fire.
I believe it would, for all practical purposes, appear the same as an explosion.
Not wanting to make a controversy or argument. Just wanting to point out a fact.
I think that this is like the Russian counterpart to the American Media’s portrayal of all rifles as AK-47’s.
All ‘tanks’ are OXYGEN tanks, no matter what is really in them. Either that or it’s just a translation problem. The original report may have said ‘compressed gas’ tanks.
Because.... the word OXYGEN is in the title of the article ?
And my point, and the point of other firefighters on this thread is that the TITLE is misleading.
OXYGEN is NOT flammable. PERIOD.
An Oxygen leak is WAY down on the list of concerns if the leak is outdoors.
The flammable/explosive gases on that truck were the cause of EVERY ‘explosion’ you saw.
NOT oxygen.
done here.
The “no smoking, oxygen in use” signs are so some schmuck doesn’t have their lit cigarette burst into flames, ignite their clothes and hair etc etc.
But the OXYGEN never burns - it just helps other stuff burn or blowed up real good ;-)
BTW, your O2 cylinders are green, right? Or come out the wall from a tank elsewhere?
Yes - increasing the O2 PPM or percentage of the atmosphere does indeed accelerate combustion. The reverse is also true.
The movie BACKDRAFT demonstrated the effect of suddenly introducing O2 to a hot fuel with a source of ignition.
I ‘hated’ that movie for one reason — They portrayed Fire Fighters as stupid - going into an active, enclosed fire with their gear open, (not even a balaclava or face shield) without a buddy, and no respirator/ rebreather etc etc.
Otherwise entertaining.
Green and 02 flow meters out of the wall have green on them.....
I think we all agree on that.
I merely noted that OXYGEN is NOT flammable. PERIOD.
Yeah... it's inflammable. (a firefighter joke).
An Oxygen leak is WAY down on the list of concerns if the leak is outdoors.
Rather like a large burst of CO2.
The flammable/explosive gases on that truck were the cause of EVERY ‘explosion’ you saw.
I find that unnecessarily redundant, but at the least we can agree that the 'fuel' for those explosions was in those tanks.
NOT oxygen.
It was Russia, could have been just about anything. None of those pesky signs to deal with either.
done here.
Thank you for your response.
