Storing Powder and Primers in a Residents

[grry10]

How much gun powder can you have in your residents legally and how must it be stored, according to local, state, federal fire codes? Are there also restrictions on primers? With component shortages these past few years I think we all may be guilty of hoarding and some may be inadvertently in violation.

I do not have an answer for you, but, if you are concerned about an accidental fire in your residence you might start with your insurance company in the event you have to file a claim to see if they have exclusions and or limits in this area.

Other than that you could Google legal storage limits in your state if you are concerned about it.

In my house I can legally store as much as my Wife will let me. Usually one closet full.

This is for Colorado, your state maybe different;
In Colorado, residential storage for personal use is generally limited to a maximum of 50 pounds of smokeless powder, provided it is kept in a compliant wooden cabinet. [1]

Storage Limits & Rules (Based on NFPA 495 / International Fire Code)

• • Up to 20 pounds: Can be stored in original containers in a single-family residential occupancy (Group R-3) without extra cabinetry.
  • 21 to 50 pounds: Allowed only if stored in a dedicated wooden box or cabinet with walls of at least 1 inch nominal thickness.
  • Over 50 pounds: Prohibited in standard residential buildings.
  • Small arms primers: Typically limited to 10,000 units in residential spaces unless kept in approved DOT-rated packaging.
  • Black powder: Usually capped at a strict maximum of 20 pounds (and some local or older codes restrict black powder much lower, or require special handling compared to smokeless powder). [1, 2, 3]

Important Local Exceptions

• • State and national guidelines provide a baseline, but local city or county fire codes can be more restrictive.
  • It is recommended to verify the specific ordinances enforced by your local fire protection district or municipal authority. [1, 2, 3]

The powder manufacturing companies put general storage information on their websites. A good review, most of us don’t follow manufacturers storage recommends-

I would be equaly interested in what the homeowner's insurance policy says.

Just curious but are you concerned due to maybe a fire or government invasion of your home? Fires happen different times different reasons. As for the other don't advertise what you have.

 

[grry10]

My concern would be that if an individual knowingly or unknowingly had a code violation and a fire it opens many issues and none of them good. For myself, I see that I need to build a storage cabinet for powder. Personally, anyone who handloads needs to be aware of the restrictions and address it in how they see fit. I didn't ask anyone to share what they have stocked, just if they know what the codes are where they live.

Wisconsin allows a maximum of 20 pounds in original containers and 10,000 primers.

Seems most codes state a wood cabinet that has one inch sides.

I store my powder a refrigerator out in my shed which is wired for electricity. Fridge is on and powder is kept very cool. I've done this for years and the powder seems to be unaffected. FWIW, the temp can easily reach 120 to 130 degrees in the summer. Between the summer heat and what heat the fridges and a freezer put out it does get hot in that shed yet the power stays nice and cool.

I worked for a large firearm retailer. We kept a limited amount of powder in two approved wooden powder bins. An inventory list hung inside of each bin. When the powder inspector came around, he would be taken to the bins for inspection. As a salesman, we were told to NEVER touch the powder in the bins. They had a separate room in the warehouse that had shelves full of powder. That's where we grabbed the powder that was actually sold to customers.

While this doesn't answer the OP's question, I thought that you would all find it interesting.

Smokeless Powder Storage Limits in a New York Residence​

In New York State, smokeless powder (a type of explosive) generally may not be stored indoors in a residence without a special permit, and local laws may impose strict limits — in some cases, as low as 14 lb for small supplies, with larger amounts requiring a magazine permit and compliance with explosives regulations LII / Legal Information Institute+1.

State law (12 NYCRR 39)​

Under New York State’s Part 39 rules, explosives — including smokeless powder — must be stored in facilities that comply with the regulations, and no indoor storage facility for explosives is allowed in a residence or dwelling unless an exception applies (e.g., during manufacture, blasting, or transport by a licensed person) LII / Legal Information Institute.
If storage is permitted, it must be in a locked “magazine” meeting construction, location, and safety requirements, and the total quantity is subject to the limits in Table 2 (Low Explosives) of 12 NYCRR 39 Department of Labor. These limits vary by explosive type and location, but for small quantities, a permit may allow up to 250 lb in a properly approved magazine Justia Law.
