:youcrazy: I said I wasn't going to do this, but what the heck. We hashed this subject back and forth on another tread I started. The long and short of that was, there is probably as many different ways of powder being stored out there as there is opinions on the subject! :grin:
I have the same problem in my neck of the woods heat and high humidty. .
Like alot of you I thought an old ammo can, or a fridge seemed to address the concerns of storage. Here's where the rub comes in though! My thread was about fire also. More than one person said in a fire that metal container becomes a shrapenal type bomb! :shocked2:
After going thru more ideas and opinions, than I can remember, one stuck. The man said check your own state regs of BP storage. :hmm:
You will find that your state most likely has storage procedures for the individual as well as bussinesses! The bottom line in my state was for an individual it must be stored in a wooden box 1" thick exterior, must have divided partitions or 1/2" thicknes. Must have handles for easy lifting, and must be paddlelocked. Also has to be marked all sides and top w/Explosives - Flamable.
Now that will put you in compliance with state code.
To me that says heat and humity are not a problem! This regulations were drafted with the aid of experts in this field, to give the best of all worlds, saftey and useable storage!
Do a Google search: storage regulations black powder (State).You may have to wade thru alot of info to get to the one or two paragrphs pertaining to you, I did! Hope this helps! :wink:
