Secure storage for powder

[Vegeta]

Hey all did a search for this but no joy,

 

Anyway I have gathered from another forum that a safe is not a safe place to store powder in the event of a fire. (see what i did there with the word safe da dum dish )

 

My question then is what the hell is secure storage for powder and what is the cook off temperature of modern powders.

 

SO say it was stored in a wooden lockable chest, house goes on fire, what would happen first? Wooden chest burns through thus not allowing the burning powder to build any pressure or internal temp of the wooden chest reaches cook off temp and boom.

 

Just wondering

Powder needs to be stored in a wooden box so that it can burst with ease.

If you kept it in a metal safe, then once the temperature reached ignition point the whole safe would become a massive shrapnel bomb.

Biscuit tin in the kitchen cupboard next to the oven?

There is always one, you probably read the instructions on fireworks with a lighter

 

If you speak to your FEO he will have drawings of what requirements are needed for a powder storage box and all the relevant drawings and material lists.

 

If he doesn't ring Essex Police because they have.

No I understand the story with a metal box. Conducts heat very well but will not burn and if its not ventilated pressure builds and boom

 

I am asking what is the ignition temperature of modern powders because I have heard about 200 degrees C and I worry that the powder would go boom before the wodden box has suffered enough structural damage to prevent pressure building up.

 

Has anyone seen tests for this on the net or anything.

No you keep it in the hot press beside the boiler to keep it dry, don't you know anything

The best way to store your 5kg limit is in loaded shells. We obtain our propellant and load it in 'one go' in an evening. Two grabbers, a 650 and an electric Dueffe professional loader = 3500 shells.

 

For the mathematically minded, 5 (kg) x 2.2 (lb) x 7000 (grains) divided by 21 (grains) = 3,666 pigeon loads. (approx)

Most of these boys are on about loading CF rifle carts, obviously powder storage requirements are similar but one question (sorry), you must find this economical compared to buying shells? I've looked into this and I couldn't make it work, what's your secret?

My secret? There is a vast reservoir of forgotten components out there resting in sheds, airing cupboards, garages and attics. All you have to do is to be in the right place... write the ad.... read the ads.... attend the auctions... and be retired like me and have the time!

 

Sometimes you get gems, like sealed cans of Schultze or Neoflak, etc,.. unopened tins of Joyce caps, boxes of purple Eley 'Pneumatic' wads, (made from cardboard when the wool for felt was needed for military uniforms etc.)

 

Latest acquisition: Box of 500 Eley printed overshot cards No.61/2. Box printed 12/6d (62.5p)

 

Happy looking!

Mung how come you're still alive and appearing on PW? and I don't mean from the threat of a blow out but of your appalling SOH
