backpacking stove gone out of control?
[ ouch ]
That's "safe" now that it's vented off. Just allow to burn out cover with spray, or you can do as our trainee did many yrs a go put flame out 🙄 then we had to evacuate due to gas leak.

can't believe people were driving past taking pictures, tbh;

That's a great idea *in theory* but what about all those cars full of people just metres away on the other carriageway?
How long will that take to burn out?
And yes, I'd want to be nowhere near that just in case it does go pop...

As long as you've put out the fire that's causing the overpressure, otherwise you get into BLEVE territory, and they are not things you want to be around.
Looks like a fairly stable flame to me. Hopefully everyone got out okay and they will just let it burn itself out.
Edit Obviously what Bruneep said about the spray to keep the temperature down. If it's propane the tank pressure will only be about 9 barg, initially.

I thought it was Binners lighting one his farts.

Weirdly I was having this discussion the other week, should road tankers have depressurizing valves in addition to relief valves. Much bigger flame, but less chance of an explosion.

Boiling Liquid Expanding Vapour Explosion
Scary stuff.
Some video of a training course I went on at RAF Spadeadam. My favourite is at 1:10 min, the 70 barg jet fire.
Edit oh and at 2:13, why you shouldn't store LPG bottles in a building.
That's a couple of miles from me right now. Should I be shutting the windows?

Nah - take all the glass out and put it somewhere safe... 😉
a LGV was stopped before hitting the bridge in Frodsham town centre main road, due to being overheight, luckily the driver noticed its now parked up but blocking road, traffic appears to be jammed up past cheshire oaks,dunkirk and chester, and the HA are cutting central barriers to allow vehicles to turn round.
Long delays on M53 through tunnel as vehicles divert the long way round.
And now there is a multi vehicle accident on the M62, all 3 lanes blocked it appears
Wow, Frodsham in the news 🙂

is that a Rapha jacket he's wearing?
Those crazy Russians...
Pah, who needs the Ruskies when you can strap one of these to your back. I want a go.
^^^^That "Jet tank" is my new favourite thing! 😀
Just remember to put the handbrake on before throttling up....... 😉
Ive just spent the last 2 hours directing our drivers off the M56 and home, stupid thing is they decided to sit in it rather than find an alternative route , words tomorrow me thinks

I went past Gary Barlow's mum's farm not long ago.
Apparently the tanker driver tried to put the fire out when he realised things were warming up and stopped, you can see the two extinguishers by the front wheel in that second photo.
Got to give the bloke credit for having the cojones to stand by a burning propane tanker with a standard extinguisher trying to put it out. If I was asked what steps I took under similar circumstances, I'd reply ****ing big ones, as far away as possible!
How long before an engine or cab fire begins to affect the pressure of the gas stored as a liquid inside the tank though?
From the pictures and the descriptions I understand that there is a vent on top, either heat or pressure activated, which allows gas to blow off vertically upwards so as to prevent a build up of pressure to the point where the tank fails and ruptures, which is when you get this devastating BLEVE.
The last time I saw that acronym was in the Iain Banks novel Complicity where a man is murdered sadistically by Bleve, apparently a favourite method of the Welsh nationalists who burned English holiday cottages in the 70s and 80s.
How long before an engine or cab fire begins to affect the pressure of the gas stored as a liquid inside the tank though?
It depends on a number of things, however the relief valves will be calculations done (although probably only once per truck design) to determine the likely maximum heat flux into the vessel (probably from a petrol or diesel pool fire) which will then give the required gas outlet rate. It's a fairly standard calculation in industry and from the photos it appears that it did the job it was intended to do.
another vehicle fire on the same road same place but other side now, and a lgv has overturned at Runcorn on the entry slip.
All tankers are shielded round the engine to encapsulate a fire below the cab, and the pressure realease valve opened to vent the gas, been a safety item since the start of boiler explosions on steam trains.
