How "cool" is cool for gunpowder storage.

Try replacing the petrol in your engine with black powder and igniting it. It wont go well I promise.

What is important, which these internet tables don't tell us, is how quickly a substance can release its energy, ie, convert its energy to heat.

And you can also add in the odd flour explosion from around the world. Maybe our wives shouldn't have flour stored in the house.

I currently have around 34 cans of powder (greater than 15 kg) which is stored in of all places my hay shed. Yeah, she'll be a ripper.
The cans are stored in two plastic drums, which have breathers.

An interesting aside is how porous the plastic powder cans that the manufacturers pack powder in are - one of my drums has only unopened cans in it. When I take the lid off the drum there is always a nice sweet smell of powder wafting out.

I store in my garage at most 2 cans (500 grams) of the current powder I may be reloading with.
If my garage, and attached house should burn down, one of the hassles I don't want is arguing the toss with my insurance company when they go looking for reasons to squirm out.

To each his own I guess.

BTW In my early stage of married life my powder (very small supply in those days) was stored in a cupboard in the bedroom. I had a can of milsurp party go off when it popped its screw cap and gave off lovely brown fumes. Haven't stored powder in main house since.

Old guy, now passed, had his collection stolen from a walk in safe in his garage using his oxy/acetylene torch to cut the lock off. Police were not amused and told him to store his gas set elsewhere, his answer was to leave the gas set where it was, but on repairing the lock he made a lockable cabinet on the inside the door right where the lock was. He wanted them to have another attempt, not a man trap, just the safest place to store black powder, in his opinion!!:cool:

Storing Black Powder in a safe is a good idea to give firemen the shits! But it would blow the fire out, with a bit of luck?
