Where are ammonium nitrate and slurry stored?

• A. Ammonium Nitrate Magazine
• B. Dynamite Magazine
• C. Fuse Magazine
• D. Blasting Cap Magazine

Answer: (A)

Storing oxidizing materials like ammonium nitrate and slurry in a dedicated ammonium nitrate magazine is about keeping a sensitive combination of oxidizer and fuel separate from other components and from ignition sources. An ammonium nitrate magazine is built to protect these materials from moisture, heat, and accidental ignition, with secure access and appropriate separation from other explosives and from potential sources of heat or sparks.

This type of magazine is specifically designed for ammonium nitrate in its various forms, including slurry, because that material acts as an oxidizer in blasting formulations. Keeping it in the ammonium nitrate magazine minimizes the risk of unintended reactions and helps ensure controlled handling and inventory.

Other magazines exist for different explosive components—dynamite magazines for dynamite, fuse magazines for fuses, and blasting cap magazines for caps. These are not suitable storage for ammonium nitrate and slurry due to compatibility and safety concerns; mixing these materials or storing them in the wrong type of magazine could significantly raise the risk of unintended initiation.
