From ACOP 415:

 

415 Metal boxes, including ammunition boxes, are not suitable and must not be used. This is because, firstly while metal is fire resistant it also transmits heat very well and secondly, because the metal container adds additional containment that significantly increases the explosive power of the powder. It should be noted that the requirements in this paragraph replace guidance permitting the keeping of black powder in a lacquered or tinned iron or steel trunk or box contained in A guide to the Control of Explosives Regulations 1991.46

 

Seems like there is a lot of inconsistency in hoe the elo's interpret the requirements then.

 INteresting, it was a while ago but he was more than happy with my ammo box bolted to the floor as long as the actual container I put the BP in and was carried in was wooden it was fine. 

Aren't we getting into silly town if we start thinking about metal jail bar type setups like Arthur mentions later?

Maybe if we weaken the ammo box it would be better and not contain as well. I suspect 15kg of BP would contain rather well in a concrete cupboard and an ammo crate would be largely irrelevant if it went off.?!?!

BP storage when discussed at ORDCON a while ago was suggested to be a standard wooden box (18mm ply with six bottle spaces and an unfastened flap lid).  This inside a cage of steel bars, this inside a plastic garden storage container.

 

This being to secure the contents from the weather (Plastic box that would melt in an accident)

Secure the contents against theft, ( prison bar type assembly that would let flames out.)

Separate the bottles in the event of a fire using the 18mm ply box that the regs have favoured for a while.

 

This arrangement being considered suitable for a full HT1 store for BP not just the "inside the home" small store.

Arthur

Can you expand on this a bit. I hope I'm not the only one who has no idea what doom and gloom you speak of.

What is ORDCON?, What is an HT1 and how does this all affect people like me who just want the basic licenses to do my hobby????

OK, ORDCON is simply "Black Powder Ordnance Conference", which is just a conference that talks about various topics including the legislation and how it affects certain groups.

 

HT1 is hazard type 1 (the .1 in 1.1), so no big deal as BP has always been HT1 as far as I am aware.

 

The regulation with respect to the storage of BP and shooters powders has been the same since MSER 2005 (although new version out soon). You can find a copy here http://www.hse.gov.u...priced/l139.pdf check out page 95 onwards for the rules. They are not too onerous. Basically all you need to do is ensure your box is in a locked room, no big hassle.

 

Hope this Helps


Phew that was close.

Crazy cat - if 'gunpowder formulations.pdf' is your own work, would you mine changing the ratio in the first box on the first page to read correctly - I suspect it's a typo but someone new might come along in the future and take it as gospel.
Cheers :)

Actually, it isn't my work, but a compilation from another forum, I'll correct the erroneous data once I find a good pdf editor.
