I'm looking to get an outdoor storage solution for a Wavian UN approved 20L fuel (diesel/petrol) jerry can which I should store outdoors.
So far a McGuiver approach is to keep the jerry can in a large wheelie bin (which would be insulated) outside. I do not want to store it indoors even in the garage.
Is there a product I can get (e.g. outdoor waterproof storage container) to store the jerry can outside? Am in Wales so it gets damp/humid and I think petrol cannot be stored below 5 degrees C so the outdoor box needs to be insulated.
Reason for doing this is the impending fuel rationing/fuel shortages.
Advice please
Fuel jerry can outdoor storage
Re: Fuel jerry can outdoor storage
Storing above 5C is about avoiding condensation. However, that should not be an issue with a full jerry can. Petrol can degrade quickly in part empty containers, but brim full should not show significant degradation even after a few years.TheEnd1 wrote: ↑Thu Apr 02, 2026 6:25 pm I'm looking to get an outdoor storage solution for a Wavian UN approved 20L fuel (diesel/petrol) jerry can which I should store outdoors.

Incidentally, the 30L limit does not apply if you simply inform the right officer on your local council. You CAN store 250L without paying for a licence. Just tell them and send them a schematic of your storage location.

Re: Fuel jerry can outdoor storage
Why would you need to insulate it? Is the fuel tank on your car insulated?
Add some Stabil to it and store it covered up,make sure the can is as full as you can get as well.
Mine stay outside under a tarp with no issues.

Re: Fuel jerry can outdoor storage
If you start storing any quantity worth making sure it's well away from the house well ventilated and ideally with a decent size fire extinguisher handy... Ive only got my shed so metal fuel cans I've added a 2kg fully automatic dry powder extinguisher on the roof
If your roughing it, Your doing it wrong

As I see it, Steel Jerry cans in good condition should only present an explosion/fire hazard if they find themselves already in a fire, or if they leak and generate fumes. Then they put you in a BAD place. Petrol is not going to burn gently.
Inside my garage was first thought, but that garage houses electricals and the CH boiler and even an occasional car, with hot engine etc. It's also attached to the house, and being closed, could suffer a build up of petrol fumes if a can were to leak.
Next choice was the shed, but that's only a timber structure, not likely to catch fire unaided, even if full of fumes. For now I've settled on a mix of shed and outside the garage, away from anything hot or electrical and shaded.

Plastic jerry cans are 5h1t. We've had two simply split for reasons unknown.
I really should get a big extinguisher for the garage. Incidentally, ALDI (or was it LIDL) had small Powder extinguishers in for a tenner today.

It's aldi saw them tonight I dont need any more extinguishers honestly
Near by stick a 6kg powder minimum imo rapid knock down and very quick...

If you are in a position to extinguish a big fuel spill you dont get a second chance

Re: Fuel jerry can outdoor storage
Don't forget that insulation on it's own won't keep it above ambient temperature , it will reach the same temperatures as the outside albeit a tad slower. You would need a source of heat if you wish to keep that wheelie bin higher than the outside world in winter for example.TheEnd1 wrote: ↑Thu Apr 02, 2026 6:25 pm I'm looking to get an outdoor storage solution for a Wavian UN approved 20L fuel (diesel/petrol) jerry can which I should store outdoors.

I know you don't want to keep it indoors but I really don't think it would be too much of a problem. I keep my diesel and a gallon or two of petrol in the attached but unheated garage . There seems to be enough heat from the freezer and what leaks from the house to keep it from ever dropping to freezing point. I have petrol in the workshop that is occasionally heated and again never drops too low.
Re: Fuel jerry can outdoor storage
I now have a 2 x 19kg outdoor LPG bottle enclosure that I plan to use to store the UN Wavian jerry cans. This enclosure is basically a mild steel box with a square cut out of 1 side to allow ventilation. There is enough room for potentially 3 jerry cans in this enclosure. This enclosure can be located 3m from the property and 1m from the property boundary and nowhere near (least 10m) from overhead services (e.g. electricity transmission poles, fibre optic), and not directly visible so discreet. And at least 8m from underground services (sewage/cold water) etc. In the scenario of accidental petrol drips the grass (which is damp near all year round) should absorb it. The only issue is that this specific location would be in the sun so would heat up a lot in summer.jennyjj01 wrote: ↑Thu Apr 02, 2026 9:04 pmGuilt tripping me for being a maveric?Yorkshire Andy wrote: ↑Thu Apr 02, 2026 8:37 pm If you start storing any quantity worth making sure it's well away from the house well ventilated and ideally with a decent size fire extinguisher handy...

I was thinking of either getting some heat reflective paint spray to keep the sun off or somehow insulating the box by using block insulation. I could build a secondary enclosure made out of timber, metal sheeting and block insulation and put this secondary enclosure over the LPG enclosure.
What do you think? If the UK has a roasting summer then temperatures could hit 30oC which does worry me with regard to the petrol cans.

I would say that as long as the cans are in direct sunlight for hours on end they should be fine. If they get too hot they won’t explode but more likely to expand with fumes which could breach the seal.
I would say ypthat you should take as many precautions as you want to ensure your safety,I’m much more of a maverick than Jenny.
