The 2,500-ton storage limit without a sprinkler system applies to which material?

• A. Bagged ammonium nitrate
• B. Dynamite
• C. ANFO
• D. Liquid nitroglycerin

Answer: (A)

The main idea is that storage requirements for blasting materials depend on how reactive the material is and how much of it you’re storing. Ammonium nitrate fertilizer, when stored in bags, is an oxidizer that can fuel a large explosion if heated or contaminated. For safety, there’s a specific threshold: you can store up to 2,500 tons in a magazine without a sprinkler system. If you go beyond that amount, automatic sprinklers are required to help control a fire and reduce the risk of detonation propagation. The other materials—dynamite, ANFO, and liquid nitroglycerin—have different hazard profiles and separate storage requirements, so the same 2,500-ton sprinkler exception doesn’t apply to them. In short, that 2,500-ton limit without sprinkler protection is a rule tied specifically to bagged ammonium nitrate fertilizer.
