Question about powder storage

[Alan]

I got like 5 different types of powder now and I'm keeping them in the original containers in a cabinet. Is that safe enough or should I be doing something else? I know this stuff can be dangerous if you're stupid about it. What's everyone's storage setup look like?

 

[Just_Matt]

Keeping them in the original containers is fine

Sealed and relatively cool environment.

Keep mine in a MTM Storage box, but I have more than you.
But they have several sizes. Small one might be better for only a Few Bottles
And if you like they come in RED!
