FAQs

1. What are the classes of explosives?

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)

For more information, visit https://www.atf.gov/explosives/explosive-storage-requirements.

2. Do I need a special foundation for my explosive storage?

It is not necessary to place your explosive storage container on a special foundation. However, a foundation such as concrete can help to provide a truly level surface. Be sure to check your local guidelines to determine if any footer is required.

3. Does my explosive storage need to be grounded?

Yes, high and low explosives should have a grounding system according to the NFPA 70 standard. NFPA 70 is the National Electrical Code (NEC) of the United States and covers every facet of the safe installation of electrical wiring and equipment. Grounding protects your building and its contents against electrical strikes and will need to be properly grounded by a licensed electrician.

4. Can DynaLoc magazines be customized?

Yes, like all our safe storage buildings, U.S. Chemical Storage can provide custom explosive storage magazines to fit your needs.

5. If storage magazines are mostly made of high-density wood, will that really contain a blast?

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.
