Speaking as a genuine fire truck chaser, THIS TRULY IS THE DAMNDEST THING I'VE EVER SEEN!!

Whatever you do, don't stop watching after you see the wreck happen.
Trust me, this video gets a LOT better after you see that!!

(p.s. credit goes to yella for finding this)



p.p.s the guy who keeps videoing this must have a death wish!

I had seen this but must add that it would make a pretty good BLEVE (boiling liquid expanding vapor explosion) training video.

I guess it's safe to assume the driver didn't survive. The car that stopped next to it was way too close.

Watch it again. Right after the truck explodes in the beginning you can see the driver exiting the driver side and running toward the concrete barrier in the median.

The bystanders were lucky. When those canisters start exploding they could have easily been hit by shrapnel.

I didn't see that. He appeared to be driving too fast when he hit that van. Where is the van?

I wondered the same thing about the vehicle he collided with. The camera perspective doesn't let us see it clearly enough after the collision.

It's not clear whether the guy from the truck ran or the guy from the van. The van was pushed into the truck in the right lane. The guy in the truck clearly hit the van from the back.

I think you're right. Good observation.

"About 36 of “gas tanks” (possibly oxy-acetylene for welding) exploded over a period of about 10 minutes after the crash. Some of them were even projected like missiles causing a very dangerous situation for onlookers. Fortunately everyone survived, including the driver who quickly ran into the woods."

Very interesting to watch from my point of view. The burst discs in the valve assemblies work flawlessly until the temperature causes the pressure to rise past the containers rated strength. They all lose integrity at the bottom which is in line with popular theory on BLEVE incidents. The flames you see shooting out is product that is escaping the burst disc (a type of relief valve) and burning. This type of incident generally requires creating a hot zone evacuation area of 1000 feet and allowing the product to just burn itself out.

The accident happened in Russia.

And the guy seriously needs to invest in some new speakers for his car...those are sooooo shot

It was quite a firework demo for sure . . . . didn't equal the Molino derailment in Nov. '79 however. In that incident the fireworks began with the explosion of 280,000 gallons of LP . . . . . then the other ones began to heat up since they were lying in the fire and two of them bleve which was quite a sight.

How much of the consist was haz mat at that incident knothead? We recently had a class where we were told that in a consist now most haz mat is put up towards the loco for terrorist reasons

Gunz, the rules governing these types of shipments require a minimum of six empty spacer cars between the haz mat cars on the head end of the train. The cars in this particular incident were picked up in Flomaton, Al and the train had six empty box cars between locomotives and the haz mat . . .

(possibly oxy-acetylene for welding)

Has to be one of the other. I would wager that they were Acetylene. Many years ago I used to work for Keenan welding supply's on Palafox st. I have knocked the tops off of a few Oxygen, Argon, CO2 cylinder. Those cylinders look pretty short to be a K3 cylinder. FWIW Acetylene cylinders are not hollow. The acetylene cylinder (fig. 15-27) is filled with porous materials, such as balsa wood, charcoal, and shredded asbestos, to decrease the size of the open spaces in the cylinder. Acetone, a colorless, flammable liquid, is added until about 40 percent of the porous material is filled. The filler acts as a large sponge to absorb the acetone, which, in turn, absorbs the acetylene

Propane, Butane, MAP are not filled with a porus meterial.

LOL More than you want to know

Thanks itchy, I could listen to stuff like that all day

True Story

One time we had a pool in the back yard.  The PH was down so I thought I would add some Chlorine and some other chemical, algeside I think..  I was in a hurry so I told the wife just pour the two chemical together while I held this glass tea pitcher. Hell, they are together in the pool, right? She did and the shit erupted and shot almost to the ceiling.  It coated my hands and when I looked down all the skin was coming off my hands.  I ran in to the shower and washed the rest that had splashed on me.  I was wearing a bathing suit.  We went to to Baptist ER but they were assing around and made me wait.  I sent my wife to the Tom thumb and she bought be a cooler and some ice.  I jammed my hands down in the ice while I waited.  It seemed like forever but at last they took me back and treated my burns. I think they used that Silver Oxide(?) stuff.  When they finished it looked like I had 2 boxing gloves on.  LOL  what a Fng mess.  
What a dumb ass........

It was probably Silvadene cream (silver sulfadiazine) which is used for burns..  It's great stuff..

On my submarines, small plastic (1 pint) bottles of chlorine granuals were stored in special plastic 1 gallon containers with locks and seals on them, then locked in seperate lockers in different areas of the sub out of the normal living areas and away from any possible exposure to water. It was not fun crawling into the areas to check on them occasionally.. They were to be opened and used if I found bacteria in the drinking water.. I never found any at all..

Jake, I'm curious . . . how do subs acquire a sustainable safe water supply? An on board desalinization system? If so, it must also include a method to contain/kill microorganisms . . . . .

Yes, an onboard system that removes the salt and everything else..  Basically, it's turned into steam and then turned into distilled water, similar to how whisky is distilled..  Alcohol turnes into steam at a lower temperature than water and the alcohol gas is cooled and turns back into a liquid....  Same thing with the water..  We normally let a few gallons of sea water into the tank to give it a little taste..  I NEVER had any bacteria or other things growing in the water samples taken in 7-8 places weekly..  Even if I let the cultures grow 4-5 days instead of 1, nothing ever grew..  

Just for info, we ran the fresh water with 90% KOH (potassium hydroxide) added to promote electrical flow between positive and negative electrodes which turned the water into hydrogen and oxygen gasses.  The oxygen was pumped into big oxygen bottles and the hydrogen was pumped back into the ocean.  Hospital labs use 10% KOH to disolve skin and other things to check for fungus if you go in with a rash..  The oxygen was returned into the air at 1 cubic foot/minute per man on board..  The oxygen content of the normal everyday air onboard was 18.5-21%  The trace elements (polutents) CO, CO2, hydrogen, freon, benzene, toluene, ozone, and a few others are normally kept a lot lower than they are in YOUR normal air..  Basically, the air is very clean and as pure as resonably practical for health and cost..  Even aerosol cans are NOT allowed with a few exceptions..  NO aerosol cans of shaving cream or deodorant........  Anything in an aerosol can is kept in a locked storage area and not used without written permission of the commanding officer..  

Ozone would come from the generators arcing between the contacts..  I had high readings once that got higher by the day until we pulled into port and they changed a big generator because the contacts were getting burned up from the arcing.  The arcing was caused by a high amount of parafin in the floor wax..  The wax evaporated over time, just like in your house..  The contract the govt had for floor wax expired and another company got the new contract, but the supply system didn't enforce the requirements of the chemical content of the wax, and thousands of gallons were in the supply chain..  
The crew normally caught colds within a 3-5 days of leaving port and 3-5 days after returning to port due to the changes in the air quality..  The air onboard, even after months under water is cleaner than the air 500 miles from the coast out in the oceans..  We knew any little thing would affect every person on the boat, so there was very little that wasn't enforced by all hands..

Thanks for an overview of the systems which you are obviously very knowledgeable and it was also very interesting! I understand why the air MUST be clean to avoid making the entire crew ill from some airborne or marine organism . . . . a lot of thought over many years has gone into these protocols.

Thanks again for a in depth answer . . .

Wooowey I would be like the truck with the blue top on it , Id put my mustang 5.0 in reverse -and how does that song go -youll never see me no mo.
