Agree with the simplified logistics to alleviate confusion (I learned reloading from a software engineer and his reloading room was, uh, creatively organized).
I did some quick research about house fires when I was trying to decide how to store reloading components. I figure that's my highest risk event. The closets burn the hottest (piles of fluffy fabric or cleaning agents provide an easy ignition and fuel), the walls of the basement are the coolest place (less ignition material). I ended up with storage tubs to keep everything dry, stored on the concrete floor along the outer foundation wall. Easy to access right next to my bench and the tub slides under the storage shelves easy enough.
I just realized Colorado probably doesn't typically have basements, but I think the same principle would apply.
