Black Powder is somewhat less dangerous than gasoline. At least it doesn't have fumes to spread out onto the floor.

Go have a chat with your fire dept. The most dangerous things in a house fire are aerosol cans. Especially now with enviromental regs forcing manufacturers to use highly flammable butane or propane instead of fire suppressing freon as propellants. An aerosol can is now a mini fuel-air bomb and highly explosive and dangerous.

Instead of the Mother Of All Bombs, we've all got a dozen or so Daughters Of All bombs in our kitchens, bathrooms and basements.

Make a "magazine" for your BP. Nail up (no glue or adhesive) a simple box out of 1" plywood with a decent pair of hinges and a sturdy hasp and shackle to allow it to be locked with a good padlock. The plywood will sheild things from fire for about an hour or so and the padlock will keep little fingers out of the goodies. Mine is in the garage under my computer room against a "1 hour" outside wall. It's also unpainted and unmarked. I never keep more than 10 lbs of BP. I keep my smokeless powders, percussion caps and primers in a similar but separate "magazine."
