I keep mine on a high shelf in my workshop , in its plastic bottles.  As long as it’s in a cool dry place , away from a heat source, or naked flame it’s ok . I think the wooden box thing is just for black powder . It doesn’t surprise me that there is confusion. The FEO’s aren’t always experts in shooting . The thing is with nitro powder , it will just burn , if you put it in a safe or a tin box it will create pressure and explode if there is a fire ,  better to just be in the open, but out of reach of kids . 

Same with black powder then. That's exactly the same. It's not an explosive. It just produces large volumes of gas very quickly when it burns and if confined can cause containtors to burst explosively. Not sure what all the fuss is about.  As you say it's better in the open in a container with low pressure resitance such as a tin with a press on lid. That way if the worst happens, it simply pops the lid off. I'm guessing most won't choose a tin as it's not airtight, but a thin flexible walled plastic bottle should offer the least resistance and be the safest if it bursts.

Blackpowder is an explosive it ignites much easyer than nitro, if you keep your can in a cabinet it will cook down in to its components (with a lot of smoke) during a fire in your house.

Blackpowder is not technically an explosive although firearms regard it as such because you can get an explosion if confined. There's a lot of controversy over this on the internet. 

A true explosive explodes if triggered. eg. Hit nitro glycerine with a hammer (not recommended if you have any!) It explodes on contact and depending on the amount may cause injury. TNT explodes when a smaller explosion causes a similar reaction in the TNT (kind of like a BIG hammer). If you light black power (trigger it) outside of any containment it simply burns. Black powder therefore is not technically an explosive. To cause an explosion you have to confine it and even then it isn't the black powder that explodes but the container it's in that explodes when the pressure of the gas becomes to high to contain, which is simply the black powder burning rapidly in the container. So black powder isn't an explosive in the true definition of the word. That's also why fireworks use black powder. It's the tightly wound cardboard tube that explodes. Take the powder out of confinement (taking them apart not recoomended), it just burns.
