powder storage

[Czech_too]

OK, my curiosity has got the better of me here. I've done a search, both here and elsewhere, and can't seem to find SPECIFICS on the proper method of storage and quantities allowed for BLACK POWDER.
I have found those for smokeless powder.
This would be for a residental application.
I guess what I'm looking for is 'chapter and verse' citing the above.

The BATFE used to give you a copy of their "Orange Book" for free, I think they now charge for it but I would contact them to see if a copy is available. If you have a local field office it might be worth a phone call. I think it is also available at places that sell fireworks making supplies.

It might be better just to search the atf site for the info. Or maybe you want the atf to know of your intrest in how many pounds of explosives are ok to store in your residence. They do have good reputation for screwing regular folks,arbitrary and capricious help, and reckless intrusion all the while aiding and abetting ANTI-AMERICANISM. They did that fine job at WACO, remember. You don't have to be a thug even. BvT

As a practical matter: Unlike smokeless, real black does NOT deteriorate over time, it is immune to cold and heat (short of ignition), and it's only real enemy is moisture. Keep it in the original cans and dry, and it will last forever.

For insurance and legal specifics, your greatest restrictions will probably be local residences for urban residential storage. I'm lucky because I have the use of a cinderblock barn in rural La. Nice and dry in there, big thick wooden door I can padlock. and not close to a dwelling. I buy it 25 lbs at a time, and just keep a month's supply or so in the house.

Maybe 4 o'clock in the morning isn't good time to do a search, or I just needed more coffee in my system.
What I've found so far is that black powder falls under the "low explosives" category.
Sec. 555.202 Classes of explosive materials.

For purposes of this part, there are three classes of explosive
materials. These classes, together with the description of explosive
materials comprising each class, are as follows:
(a) High explosives. Explosive materials which can be caused to
detonate by means of a blasting cap when unconfined, (for example,
dynamite, flash powders, and bulk salutes). See also Sec. 555.201(e).
(b) Low explosives. Explosive materials which can be caused to
deflagrate when confined (for example, black powder, safety fuses,
igniters, igniter cords, fuse lighters, and ``display fireworks''
classified as UN0333, UN0334, or UN0335 by the U.S. Department of
Transportation regulations at 49 CFR 172.101, except for bulk salutes).
(c) Blasting agents. (For example, ammonium nitrate-fuel oil and
certain water-gels (see also Sec. 555.11).

It needs to be stored in a "type 4 magazine".
Type 4 magazines. Magazines for the storage of low explosives,
subject to the limitations prescribed by Secs. 555.206(b), 555.210(b),
and 555.213. Blasting agents may be stored in type 4 magazines, subject
to the limitations prescribed by Secs. 555.206(c), 555.211(b), and
555.213.

Construction of a indoor type 4 magazine.
Sec. 555.210 Construction of type 4 magazines.

(b) Indoor magazine--(1) General. Indoor magazines are to be fire-
resistant and theft-resistant. They need not be weather-resistant if the
buildings in which they are stored provide protection from the weather.
No indoor magazine is to be located in a residence or dwelling. The
indoor storage of low explosives must not exceed a quantity of 50
pounds. More than one indoor magazine may be located in the same
building if the total quantity of explosive materials stored does not
exceed 50 pounds. Detonators that will not mass detonate must be stored
in a separate magazine and the total number of electric detonators must
not exceed 5,000.
(2) Construction. Indoor magazines are to be constructed of masonry,
metal-covered wood, fabricated metal, or a combination of these
materials. The walls and floors are to be constructed of, or covered
with, a nonsparking material. The doors must be metal or solid wood
covered with metal.
(3) Hinges and hasps. Hinges and hasps are to be attached to doors
by welding, riveting, or bolting (nuts on inside of door). Hinges and
hasps must be installed so that they cannot be removed when the doors
are closed and locked.
(4) Locks. Each door is to be equipped with (i) two mortise locks;
(ii) two padlocks fastened in separate hasps and staples; (iii) a
combination of a mortise lock and padlock; (iv) a mortise lock that
requires two keys to open; or (v) a three-point lock. Padlocks must have
at least five tumblers and a case-hardened shackle of at least \3/8\
inch diameter. Padlocks must be protected with not less than \1/4\ inch
steel hoods constructed so as to prevent sawing or lever action on the
locks, hasps, and staples. Indoor magazines located in secure rooms that
are locked as provided in this subparagraph may have each door locked
with one steel padlock (which need not be protected by a steel hood)
having at least five tumblers and a case-hardened shackle of at least
\3/8\ inch diameter, if the door hinges and lock hasp are securely
fastened to the magazine. These requirements do not apply to magazine
doors that are adequately secured on the inside by means of a bolt,
lock, or bar that cannot be actuated from the outside.

All this pretty much answers all my questions and then some. There's a lot to digest here and at least TRY to adhere to.

Here is a link to Ohio Fire Code:

https://www2.iccsafe.org/states/ohiofire/OH_Fire/fire_frameset.htm

You're looking for Section 33, Explosives, which classifies BP as a low explosive, with a storage limit of 50 pounds. There is info on magazines, etc.
