Req 2B-e — Black Powder Storage Safety

Black powder is classified as an explosive, not merely a propellant. It is sensitive to spark, flame, friction, and static electricity. Improper storage can cause a fire or explosion. These rules are non-negotiable.

Storage Rules

Store in the original manufacturer’s container. Black powder containers are designed to limit the consequences of accidental ignition. The lid is intended to blow off rather than allow pressure to build. Never transfer black powder into a glass jar, metal can, or any non-approved container.

Keep in a cool, dry location. Heat increases the sensitivity of black powder. Moisture can degrade it. A cool, dry area away from direct sunlight and heat sources (furnaces, water heaters, stoves) is required.

Store away from any ignition source. No open flames, no smoking, no sparks, and no electrical equipment that could produce a spark. This includes keeping black powder away from workbenches where grinding, welding, or soldering takes place.

Store separately from percussion caps. Caps are themselves a source of ignition. If stored together and a cap detonates accidentally, it could ignite the powder. Keep them in separate locations or at minimum in separate locked containers.

Store separately from firearms. A loaded firearm near a powder supply creates an unacceptable risk chain.

Limit the quantity stored. Local fire codes and federal regulations (enforced by the ATF) limit how much black powder an individual may store. Common residential limits are 1–5 pounds. Know your local laws.

Keep locked and inaccessible to unauthorized persons. Children, unauthorized family members, and visitors should not be able to access stored black powder.

Label the storage location. If your local fire code requires it, mark the exterior of the storage area so firefighters know explosives are present inside.

On the Range

At the range, only the amount of powder needed for the session should be out. The main powder supply stays in its sealed container, away from the firing line. Powder is measured and poured using the powder measure—never pour directly from the container into the muzzle, because a residual ember in the bore could ignite the stream of powder back to the container.

The Counselor Conversation

Be ready to list at least five specific storage rules and explain the reason behind each. The counselor may ask: “What would happen if you stored black powder next to a furnace?” or “Why shouldn’t you pour from the main container?”
