Having recently moved house i thought it would be a good time to reassess my chemical storage system.
I have decided that the metal shed furthest from the house is the place for fuels organic solvents, metal powders, organic fuel benzoates etc and fire wood. This is padlocked for security i also use an old fridge to store flammable organic solvents in and another to store metal powders etc in these are also padlocked for security.
I keep oxidizers in another locked shed with Ammonium perchlorate stored in one metal box and all other oxidizers in another metal box both locked.
Acids are currently in the fuel shed but will be moved to a small plastic shed as soon as i have it in place.
The very small amount of poisons i keep are in a locked ex medicine cabinet in the house.
I think the fridges are a good cheap way to store some of the more dangerous chemicals as i believe if they can keep heat out they should at least give some fire protection, they are also easy to secure. The only problem i've found with them is the plastic on the inside does seems to go a bit brittle with long term exposure to some organic solvents.
I think this is a good system but i would be interested to hear wat others do, also bare in mind that now EPP is live security is going to be more and more of a issue as you will have to declare any losses.
