Safety question

[ranger335v]

"...anyone ever known a primer to ignite spontaneously?"

No, not to my knowledge. And I've been doing this since '65.

I'm still loading and using primers that were made in '65

(Inheritance from a departed uncle)

EDIT: they packed them a lot different back then too. Stacks of 10 next to each other. Not all separated by enormous plastic trays like today. Much easier to use.

Lost Sheep:

For powder, you don't need as much strength or thickness of the structural plywood, but a fire-resistant lining (e.g. 5/8-inch, "fire-code" drywall sometimes called Type X has twice the fire resistance of normal sheet rock/drywall). This would protect the powder from fire from another source (cooking or electrical for example) and tend to contain the heat from the powder if it were to somehow ignite (except what escapes from the necessary pressure vents). Don't forget the bottom. Do all six sides.

I recently decided to build a powder box. I checked several places on the net and went with OSHA.
"Exterior ply, 1" thick (all six sides), rabbetted joints using wood screws on the rabbetts."
As there is no 1" plywood available in my neck-of-the-woods, I used 5/8" + 1/2" screwed together (about 1.1"). I also used the different thicknesses to form the rabbets at all the joints.
Mine is fairly small @ 24"wide X 12" deep X 31" tall. I built it like a miniature cabinet with two compartments. One opens from the top, and one opens from the bottom front. Both "doors" are self closing. I sawed formed four small 4"" legs" from extended sides and front ply.
It sure won't blow away, as it's heavy and solid.

Not unless your house burns down.

That will set them off, but it's about the only thing that will.

Primers & smokeless powder are far safer in your house then aerosol cans of hair spray, insect spray, lawn mower gas, BBQ grill tanks, and any number of other supposedly "safe" household products.

I can be characterized as a 'Safety Sally' (to quote a youtube gun video blogger) but I tend to store all of these listed items outside of my house - in a shed/storage box/etc.
We generally don't buy hair spray, and I do break my own rule on insect spray, but all of the others are never allowed in the house or attached garage. And in the garage, where I keep an exotic car or two, I have heat activated halon sprayers. Turns out that cars catch on fire quite often after they've been shut off. I don't mind losing the car, but I don't want to lose my house for a hobby of mine. So practicing my thesis, I'd keep these things apart and outside the house except when I'm using them.
Yes, I'm hopeless.
