Frequently Asked Questions
Each class requires a unique storage solution to ensure optimal safety and management. Type 2 is for storage of high explosives, Type 4 is for storage of low explosives, and Type 3 are day boxes that are used to transport both high and low explosives.
Our Type 2 and Type 4 explosive storage magazines are available in both indoor and outdoor styles, and every storage type we offer features theft-resistant, weather-resistant, and fire-resistant construction.
For storage purposes, federal requirements classify explosive materials according to their velocity. There are three classes of explosive materials, per ATF 27 CFR 555.202:
- High Explosives – explosives which detonate by means of a blasting cap (dynamite, emulsions, flash powders, etc.)
- Low explosives – explosives which deflagrate when confined (black powder, safety fuses, ignitor cords, “display fireworks,” etc.)
- Blasting agents – explosives consisting of fuel and oxidizer, intended for blasting and unable to detonated by a No. 8 test blasting cap when unconfined (ammonium nitrate-fuel oil and certain water-gels)

Absolutely. Like all our safe storage buildings, U.S. Chemical Storage can provide custom explosive storage magazines to fit your needs. A common addition is to mount a capbox on the outside of a type 2 indoor mag for convenience and safety.

No. A common misconception is explosive storage magazines will contain a blast inside the unit—this is not the case. Explosive storage magazines work as a safeguard against theft and accidental detonation by improper storage and the environment.
Yes, if the unit is placed outside. High and low explosives that are placed in outdoor magazines should have a grounding system according to the NFPA 70 standard. Grounding protects your magazine and its contents against lightning strike, and it will need to be properly grounded by a licensed electrician. For more information, please refer to NFPA .
Blasting caps, detonating primers, and primed cartridges should not be stored in the same magazine as other explosives. That is why cap boxes are vital. They are portable like a type 3 daybox, (2 man lift) and do not have wheels. Our DynaLoc™ cap boxes are constructed to be fire-resistant, weather-resistant, and theft-resistant.

Explosive Storage Magazine Types
Explosives are used in a variety of industries, from mining and law enforcement to entertainment and fireworks displays. Due to their inherent dangers, handling and storing these materials require strict adherence to federal safety standards.
- Type 1 – Permanent storage for high explosives
- Type 2 – Portable storage for high explosives
- Type 3 – Temporary, attended storage of high explosives (known as “day-boxes”)
- Type 4 – Storage for low explosives, suitable for indoor or outdoor use
- Type 5 – Storage for blasting agents
Each magazine type adheres to specific ATF requirements for construction and security, ensuring that explosive materials are stored safely and in compliance with federal regulations.
Safety Considerations for High and Low Explosives
The term “high” and “low” in referring to explosives does not indicate the danger or the intensity of the explosions they can cause. It refers mainly to the detonation velocity.
- High Explosives (e.g., RDX, PETN, TNT, C4, water gels, and emulsions) detonate by means of a blasting cap and require secure storage to avoid accidental detonation. They detonate greater than the speed of sound which creates a powerful shockwave that causes the damage, producing a “shattering” effect. However, they are considered generally more stable since they require a detonator.
- Low Explosives (e.g., black powder, flash powder, fireworks) are more sensitive to heat and flame, requiring extra caution and proper confinement to prevent accidental ignition. They deflagrate more so flame accompanies their detonation. Low explosives have slower reactions, are often used as propellants to produce a pushing effect, and must be confined in some sort of container in order to explode rather than merely burn.
