At sleep this morning after a flight back from Shanghai, I was awoken by a huge explosion that shook the house for some seconds and set off countless car alarms. It really woke the neighbourhood too, litterally This was at 06:02 according to the bedroom clock. My wife and I could only imagine that an aircraft had crashed as over time there were more, smaller, explosions. By now very wide awake, we turned on BBC News 24 to hear eye witness reports that a fuel depot near M1 J8 has exploded. Does any BRer no more?

Don't panic! - Doc
From BBC site:

Motorists urged not to panic-buy

Police and petrol companies have urged motorists not to panic-buy fuel after the explosions at the Buncefield depot.
As reports come in of long queues at petrol stations, authorities said there were sufficient alternative supplies for London and the South East.

The Petrol Retailers Association said there would be only "short term disruption to supply".

"No-one should be concerned about availability for fuel over the next few days," it added.

The Buncefield site may be a main supplier for the South East and London regions, but there were a number of other depots and storage facilities that would be able to fill the gap, authorities said.

We have no indication at this stage that this explosion will cause fuel shortages.

"We strongly advise against this as recent events have shown that panic-buying alone can cause fuel shortages."

or, from

The cause of the Flixborough explosion was a release of about 50 tons of cyclohexane, probably due to failure of a temporary pipe. The flammable cloud was ignited about 1 minute or so after the release. A very violent explosion occurred. The blast was equivalent to an explosion of about 16 tons of TNT.

Flixborough was a process plant: bellows section of pipe carrying flammable liquid at temperature failed: gas cloud ignited. Killed 32 I believe.

{Thread merged with "huge explosion" as discussion relating to this already going on. DD}

Just like when we had the refinery blockades , it only seems to take a few hours to bring hundreds of morons out ,desperate to squeeze fuel into their tanks.
This morning by 1030 one of the Tescos in Aylesbury had to cope with a queue of vehicles at the filling station, which reached back to the entrance. This was despite police announcements that there are contingency plans to supply filling stations normally serviced from Buncefield.
It makes me really angry and sorry for the few people who genuinely needed fueltoday. I dread to think how we will cope if our society ever suffers any real, prolonged crisis.
In this respect, it would help if filling stations switched to a rule in these circumstances:

YOU WILL BE CHARGED £15. IF YOU CAR CAN ACCEPT £15-WORTH OF FUEL ,IT WILL BE LIMITED TO THAT .IF IT CANNOT , THE BALANCE WILL GO TO CHILDREN IN NEED. IF YOU CO NOT ACCEPT THIS CONDITION, GO ELSEWHERE.

I'd make it £25.00 min charge - there are very few cars that take less than £30.00 for a proper fill up, and very few people who need >75% full at any time.

Same for me really. I put £10 per week in, every Wednesday night. Shall I do any different? No. (Unless I run short of course). Thing is, putting that amount in, people probably think that I?m panic buying too, but that?s enough to get me 120miles, which is practically all the miles I?ll do in a week.

I must be honest, when I heard of it, the thought of going out and filling my tank NEVER crossed my mind. Just assumed that other remaining 4 larger storage yards would make up the ?shortage?.

The problem, as I see it, is that very few people give credence to any 'official' announcements (see my post above re the allegation that these fire fumes are not toxic.)

A few years later our beef was banned all over the world and millions of cows were slaughtered at our expense. A few weeks ago the Government said don't panic buy fuel hurricane Katrina won't affect anything and so everybody went out and brimmed their tanks - not because they needed to but because they had been officially told that thay DIDN'T need to!!

Just as an observation, panic buying fuel in the North East doesn't seem to have reached the levels of those down south. The forecourts are a bit busier, but not exactly packed. I'd say, they're about 20% busier than normal. Are they still queuing up near you?

It is really absolutely amazing that no one was killed and that the two seriously affected from the 39 injured will, it is stated, recover over time. The reason would appear to be the fact it was so early on a Sunday morning.

What's the problem with having recyle air con on? Must be better than letting all the crud air in through the vents. Can someone enlighted please.

Huge Explosion - Gromit {P}
Growler asked: "I was watching BBC World here in the tropics and the reporter announced that the smoke was "carcinogenic but not toxic". Er, is there a difference or simply a fine distinction I must have missed?!"

Yes, there is a distinction: "toxic" indicates that short-term exposure to the substance can be fatal. The risk of developing cancer from most substances termed "carcinogenic" becomes significant when you are exposed to the substance over a long time.

So, for example, exposure to these levels of smoke over a few days until it disperses would not be as risky as, say, working in an enclosed warehouse with a diesel-engined forklift truck throughout your working life.

As to why approval was needed to use fire-fighting foam, the foam is a mix of nitrogenated bulls blood and fluorinated surfactants which form a stable foam at high temperature. It doesn't degrade well, so as another poster rightly pointed out, its wiser not to start using it until you can complete the job properly.

In many cases, oil fires are also allowed burn themselves out - its far safer than sending fire crews in among the tanks full of fuel that haven't (yet) ruptured! The priority will be to contain the fire so surrounding property isn't damaged.

Blue
Huge Explosion - Happy Blue!
Can someone please tell me why they had to wait for environment go-ahead to use the foam?

Firstly, the foam presumably has been developed over the years to be as kind to the environment as possible and it to be use as quickly as possible. Delaying using it becuase of environmental concerns defeats the purpose.

Secondly, the longer the fires burn, the more pollution is released into the atmosphere, where it can do the most damage.

We all know that the most efficient way to burn fuel is in a controlled environment, like inside an engine with a catalyst at the end of the exhaust manifold.

Which do-gooders got involved?

The foam used to be derived from cow's blood! Prhaps there is some newer version!

But a burst 3 million gallon tank would use up that bunded space, so any foam would run off the top, surely?

I was drinking with my mate last night who works for one of the foam producers. So far they hadn't been asked for supplies but he felt that the situation will help the company vastly at it's year end... They usually reckon on at least one major a year, this one was just a bit late in coming...

It's pointless starting with the foam until there's enough there to finish the job apparently.

And while I'm at it...

What effect would two days of raging fires have on the bunding, and any drainage systems.

I've seen bunded areas, sure, but they are designed to catch spillage I would imagine, not designed for these conditions I would suggest.
Huge Explosion - Armitage Shanks {p}
The bunding is huge earth banks so they certainly won't burn and from the look of the fire so far there isn't much left of any one tank's contents to overfill its catchment area ie I think there is probably still plenty of room for foam and water around each tank. The bunded areas are not drained as that would defeat the object of catching any spills or escaped liquid If a tank leaks the contents are held within the bunded area.

The bunded areas must have some kind of drainage, or they would turn into lakes! I understand that they would not drain freely into water courses - that would kind of defeat the point. There would be some sort of trap or mechanism in place somewhere - and how would they stand up to the conditions.

Hope they have been more careful since this (another couple of feet of earth needed perhaps?):

The bunds we design are usually reinforced concrete (on a smaller scale than at the fuel depot). If required we sometimes incorporate falls and a sump, so if too much rainwater collects, they can pump it out. In summer the rainwater usually just evaporates off.
We dont design earth ones, but they should have some form of impermeable liner, eg. concrete, or 1 metre thick clay, for example.

Re: Red Adair, my dad was talking to someone who worked for an oil company a few months ago. He was saying that if you ring Red Adair's office, you get a recorded message which says, "If you wish to be put through to this office, you will automatically incur a £25000 connection charge."!

I guess they have been waiting until all is in place.
Foam puts a film on top of burning liquid and deprives fire of oxygen. Heat is only removed by cooling therefore if foam skin is not maintained re-ignition will occur hence there must be enough foam to cover and maintain. One problem will be getting blanket in place the air convection / updrafts will make it extremely difficult. It maybe better to let it burn a little longer until liquids with a low ignition point all burnt out. Firemaster must be very strong and only move when he is ready.
Red Adairs biggest asset was the ability to tell everybody to leave him and his men alone until he and his equipment were ready to go.
Re-ignition is the major hazard, they will be cooling the place for a long time (week?) after the flames are out.
Good luck Mr Firemaster and don't let the panic merchants force your hand.

Why the huge explosion, usually these start as fires and quickly escalate. What could cause an explosion other than sudden ignition of vapour in a confined space.

Two Jags is an ex merchant marine steward. he should remember his basic fire training and hopefully he will stay in his place and take the Firemaster a nice cuppa.

Re Red Adairs answer phone, if you have let a well get away from you the time taken to make the call will have paid for it. Mr Adair used to order equipment the Oil Co would pay and Mr Adair would keep it after the job. Don't know if this still applies but if you are dumb enough to get into a bad position you deserve to pay.
I agree with thoery of explosion in confined space, most likly static. Bomb would need a lot of knowledge - type fluid in tank how full tank was and placement of device.
Hope all goes well over the next few days

What could cause an explosion other than sudden ignition of >> vapour in a confined space. I doubt this was an open air
explosion due to the damage cause (most damaging explosions >> ocurr when explosions are initiated in a sealed envelope).



It made me wonder too why there had been such a big explosion. But if fuel vapour mixes with air in the right proportions it will explode like a bomb when ignited. So sufficient vapour could have leaked out and weather conditions could have allowed it to mix in the right proportion. If it had been really windy, the explosion might not have happened. So did they have sensors that could detect vapour leakage, and if so, did they work?
Of course I'm only guessing.

Its like the "fuel/air bomb" that the US military has, which releases a big cloud of propane, then ignites it when its assumed to be the correct concentration in the air.

Don't mean to be a cynic - but how long would one of these large tanks burn if ignited? I am thinking around 3 days?
;o)

Regarding bunds - have been watching the coverage and haven't seen any obvious huge earth mounds. Guessing the fuel tanks are sunk into enclosures, and maybe water/foam/fuel being pumped to an empty tank or storage device as it is filling these bunds.

Went to fill my bike tyres this morning and the local petrol station was shut (Newbury). Not sure if this was due to lack of fuel - didn't see any signs and was in a rush. Anyone else seen evidence of fuel shortages?

Needn't have rushed either - BIB were escorting a 'plain' blue lorry up the A34. I managed to nip in behind the two riders up front who were cutting through traffic at 80+. Quickest ride to work ever ;o)

Still burning at 08:30/09:00 today. Extent of smoke drift very apparent viewed from north London.
Huge Explosion - Altea Ego
The tanks themselves probably wont combust unless they are ruptured allowing air in to provide oxygen.

So something leaked vapour, it hung around getting denser and bigger, and ignited, probably split open a tank which then exploded and split open the next tank etc.

Once you have a nice big fire going you only need to heat up the adjacent tanks to the point they burst and combust.

Possibly a BLEVE: boiling liquid expanding vapour explosion. Modelling for predicting the effects of such events is (or should be) routine in risk assessment. Won't go any further into speculation on causes.

I didn't realise that detailed modelling of blast loads on structures was so commonplace. It is a feature that has only relatively recently been added to one of the codes that I have used for more general structural analysis.

Flixborough (Nypro as was) gave many lessons re site structures, particularly control room siting. CIA (Chemicals Industries Association) guidance on design may be known to you.

No, I have never done any chemical industry work. For a structural seismic assessment project I was involved in, I used a finite element code, which was written by colleagues in a sister office of the company I worked for at the time. During my (slow and tedious - I'm not much good with FE) learning curve with the software, I met the chap who developed the software a few times, and during discussion with him, I found that the addition of blast capability to the software was causing him major headaches! This was about 2 years ago, hence my surprise at the idea of blast modelling being common.

Can you tell me what models the damaged cars were in the TV shots.
With door skins missing it is a case of clues like the shape or the badges on the wheel hubs.

While this thread may not be in the same league as;

"Do you rev your engine before swiching off?"

or

"Do you have a name for your car?",

I think that discussion about the provisions and infrastructure which supplies our fuel, and methods and techniques related to extinguishing fuel fires may just qualify as being related to motoring!

Dragging this further back onto motoring.

Reorts coming out today say it may have been started by a tanker driver, hitting the emergency kill switch on his rig when he saw/smelled the vapour cloud.

Now assuming this is the case, assuming the driver acted correctly (one would think turning off is a good idea) one would assume an emergency kill switch on a tanker was "spark proof"

Don't they normally have a plastic skin over them?

Personally I'd have left it running if it didn't, diesels being compression ignition...

I was surprised to hear a tanker driver say he filled up the night before and was arriving to start his shift without queueing to fill up.
I would have thought it better to only allow vehicles on a site, even like that for the absolute minimum period.
Even though they have protected electrics like the battery cut off switch demo-ed on TV lunchtime there must still be added risk.

I was looking at the tanks as they were cooling them down yesterday - after three days of intense heat from a fuel fire I was quite surprised that they still stood largely intact. What sort of steel do they use for these things, and why don't they use the same grade for *very* tall buildings??

They probably do. The problem with steel in tall buildings (and you'll have to bear with me, i'm a surveyor not an engineer) is that steel loses it's rigidity and goes floppy once it reaches a certain temperature, rather than melt. Hence the building collapses.

the current UK requirement is for 1, maybe 2 hours fire protection to steelwork, mainly by intumescent paint or board, i.e. enough time to get people out. The building is secondary, and to an extent sacrifical. If a fire was sufficently bad enough to affect the steel, you'll be looking at pulling it down anyway, because everything else will have gone. And new build is not much more expensive than modifying and refurbishing an exisitng structure.

So very tall buildings are designed to collapse in a fire? I didn't know this! I work in one sometimes!

And if the top floor of a VTB had a fire, the whole building is designed to collapse?

What temperature does this steel floppiness occur at?

Why send fire crews into a VTB if they are designed to colapse?

Does your car have a name? (motoring)
Huge Explosion - Blue {P}
The whole building isn't designed to collapse, it's deigned to withstand the fire for 1 or 2 hours and then perhaps be beyond repair, but still standing. In the example that you give the steel would become soft and the top floor would require demolition, however I'm sure the reast of the building would be saved.

As I understand it, the reason the twin towers collapsed was because the steel in the damaged sections softened, the floors holding it all together gave way and this lead to the top of the building dropping down several storeys, picking up momentum and therefore dragging the undamaged lower sections of the towers down with it.

This was made worse as large areas of fireproofing were missing at the time of the fire, and the fact that the circumstances weren't exactly given in the original design brief...

Talk of steel softening at temperature is just as relevant to exhaust valves and brake discs as it is to civil engineering uses of the material.

No, the fire would only affect the top floor. The steelwork supporting the roof is not protected however, and could in theory collapse earlier

Pass, very very high though

You have a 1-2 hour window. buildings over 7 storeys have fire fighting lifts i.e. a lift within a protected shaft that the fire fighters can use to get to the fire. Under 7 storeys, they use the stairs.

No it's a lump of metal with four seats and a steering wheel.

What happens if the building is exactly 7 storeys high? ;-)
