Yesterday I took my fuel can (http://www.amazon.co.uk/Anti-Spill-P.../dp/B002XN0624) to the garage to fill it up so that the lawn mower could be refilled. But as I was putting the fuel in the car first, it occurred to me that I would be leaving my car in full daylight for the remainder of the day, and that it does get quite hot in there.

So I left it until the end of the day before filling up the fuel can, to avoid leaving the full fuel can in the car in the full glare of the sun.

Was I right to be cautious, or was I being overly paranoid?

The car doesn't have a covered boot, so whilst I could put the can in as shady as possible a spot in the car, I couldn't really prevent the can from being exposed to the greenhouse that is my car on a working summer day.

I would day you were right.

Petrol vapour is explosive.

Minimise chances of it occurring and don't rely on no ignition sources
being available.

Few petrol cans are pressure tight and hot vapour does escape,

And in case it hasn't been metioned elsewhere, unleaded petrol is
[apparently] far more carcinogenic than leaded due to the additives that
they use to replace the lead content - and shouldn't be stored in a car boot
or sealed room on a regular basis or for long periods of time.

Please don't ask me for links, but the info us from a HSE course that I and
several employees attended before I retired many years ago, which resulted
in the PITA of having to carry full AND empty petrol cans on open-backed
vehicles.

The traditional WW2 jerrycan style are.

you open it a times in the summer.

In the "old days" everyone kept a 1-2 gallon can of petrol in the car.

If it's shaded and upright it will be fine.

Go back to the real Old days then the can was often stored on the
running board,

In some estates and hatch backs shading could be difficult.
An answer could be a fuel can of less than normal size,you can get
smaller ones for motorcycle use. And place that in one of those
plastic insulated picnic boxes or large cool bags with some of those
pre frozen gel packs or if there is enough room just a plastic milk
container filled with water and stuck in the deep freeze for a while
will do the same job for some hours.

Whether that is a practical solution may depend on how thirsty the
OP's mowers is. That's igonoring any protests from another half about
using the household inventory of domestic equipment for a use they
don't appove of.

No you are not being paranoid. Many years ago I had a Datsun

hatchback, no boot as such, and I always kept a gallon of petrol in a

purpose-made low-profile metal petrol can behind the back seat. On

arriving home late one afternoon, when the car had been parked in the

hot sun all day, I noticed that the petrol can was actually bulging,

so I thought I'd just release the pressure before putting the car in

the garage. But the pressure was so high that as I loosened the cap it

blew right off, and the can went off like a foam fire extinguisher. A

jet of petrol foam, about two inches wide, shot out of the can like a

fountain and went about six feet into the air, and continued for

several seconds before the can finally emptied. The petrol was

obviously well above it's boiling point and instantly boiled as the

cap was released. I was absolutely drenched in petrol. I count myself

very lucky that there wasn't a spark caused by static or whatever when

the can popped like that, because at best I would have been very badly

burnt, and at worst died from burns. It's an experience I shan't ever

forget!



Never, ever, keep a can of petrol exposed in a hot car! I'm not sure

I'd even keep a can in a closed car boot.

At a guess, that's why metal 10l and 20l jerry cans don't have screwtops,
but have the bayonet-style hinged lids. The lid CANNOT, physically, open
until some point after the pressure's been released.

That BP would be at atmospheric pressure though. Significantly
different in a container in which the pressure had risen.

Let's forget posted that shall we...


I've seen the top blow off a metal can when it was loosened a turn or two.
Scary to say the least

I've never got anything like that with the WW2 style jerrycans.

Can some of you buggers snip the ever expanding GG **** please. It's
dead boring having to scroll through pages of blank lines just to see a
one-liner.


I firmly echo that request its a PITA to scroll down and further still
for a one of two line reply. I'm more akin to skip that post and go to
the next easily readable one!...

Yes, the BP would be *higher* not lower.

Only while it's still pressurised. Take away the pressure and
whoosh...

Think car cooling systems, they can still go whoosh when still hot
but below 100C. Maybe there is something like a fizzy drink
mechanisium taking place? Under pressure more air gets dissolved into
the fluid, remove the pressure and the air comes out of the fluid all
of a whoosh.

Indeed - but there's no way that petrol got to 95C!

Fizzy drink is carbon dioxide, which is quite soluble in water under
pressure. Air, OTOH, is not particularly soluble either in water or in
hydrocarbons.

Nothing like in fact.

Doesn't happen with petrol.

It sounds like a very badly made can. After all why should the cap be

No idea of the make, but it was rather like one of these, but red.

I have a vague recollection that the really old cans (red rectangular
ones in metal) had a slightly tapered thread.

Not sure what features it has to make it "explosive proof".

I wasn't doubting your experience, just that unless the can had got up
to well over 100 C I can't see a physical mechanism to explain that.
Now, whether there might be a *chemical* mechanism, e.g. acid in the can
as well as petrol which resulted in a significant overpressure from
hydrogen, I don't know. There are probably quite good ways to "booby
trap" fuel cans, but I guess we should not be discussing that these days.

A BBC "effects" man once told me that the standard "exploding" car on
film/tv is done with a traditional five litre oil can containing petrol,
plus an ounce of gelignite.

It has a metal mesh inside the tank, which spreads heat and is supposed
to prevent fuel exploding. It used to be touted as something you wanted
in your car if you took part in motor sport. There is a cut-away view of
the can he

Could the rapid expulsion of the pressurised air from the can create a simulateously low pressure zone around the surface of the (say) 60degC petrol, which then boils / expands exiting the can, further reducing pressure in the can? Or something similar?

No, that doesn't happen in a way that would produce the effect he got.

No you are not being paranoid. Many years ago I had a Datsun
hatchback, no boot as such, and I always kept a gallon of petrol in a
purpose-made low-profile metal petrol can behind the back seat. On
arriving home late one afternoon, when the car had been parked in the
hot sun all day, I noticed that the petrol can was actually bulging,
so I thought I'd just release the pressure before putting the car in
the garage. But the pressure was so high that as I loosened the cap it
blew right off, and the can went off like a foam fire extinguisher. A
jet of petrol foam, about two inches wide, shot out of the can like a
fountain and went about six feet into the air, and continued for
several seconds before the can finally emptied. The petrol was
obviously well above it's boiling point and instantly boiled as the
cap was released. I was absolutely drenched in petrol. I count myself
very lucky that there wasn't a spark caused by static or whatever when
the can popped like that, because at best I would have been very badly
burnt, and at worst died from burns. It's an experience I shan't ever
forget!

Never, ever, keep a can of petrol exposed in a hot car! I'm not sure
I'd even keep a can in a closed car boot.



Sod that for a lark!!. Whenever petrol's needed we go down to the
filling station collect the juice and it comes straight back here.

I carry some dicey things around in my estate car but I'm buggered if
I'd want to go any distance with a can of Petrol on in the back even if
it was a very stout strong metal one with a leak proof filler cap and
most these days are flimsy plastic affairs...

Since they opened a Morrisons within easy walking distance, my gardener
simply walks down with the can and hands me the receipt when I next see
him, rather than him relying upon me to remember to buy petrol on one of
my about once a fortnight visits to a filling station to buy diesel.

Mine is a plastic one, and it's more spherical than when it was new, but
it's still pretty stout. Never had problems with the cap either.

A can of diesel lives in the car, and the petrol comes with us on
holiday for stoves.
