Funny picture and men have made errors also. We always need to be aware of every detail.
I was there to see an accident from a reloading mishap. A man had taught his wife to reload rifle cartridges. He showed up at the range for a registered match. Took his place on the line. The targets came up and the strange sound of a gun blowing up was heard. Well over a dozen pieces of the rifle were recovered, including the pieces in the mans face. She had filled the cartridges with Winchester 296 magnum pistol powder instead of Winchester 748 rifle powder.
My reloading room is a large closet in the basement, climate controlled, maybe 8x12. I have a combo lock door knob on it, to keep the kids out. One day while I was away on a deer hunting trip, wife asked what the combo was. So I gave it to her.My wife has never been in my reloading room. Frankly, I doubt she ever will, or cares to be in it anyway.
