Which combination of explosives can be stored together?

• A. Detonators and blasting agents only
• B. Detonators, blasting agents and explosives
• C. Only blasting agents
• D. Explosives with non-explosive materials

Answer: (B)

Storing explosives is about safety systems that control what can coexist in a designated storage area. When a storage facility is approved and designed for mixed storage, it provides separate, protected spaces and safeguards to prevent any initiating event from one item reaching another. In this context, all three categories—detonators (the initiators), blasting agents (the main explosive material), and other explosives—can be kept in the same storage setting as long as the magazine is designed for it, access is controlled, containers are appropriate, and required precautions (like segregation within compartments and proper distance from ignition sources) are followed. The idea is that the storage system itself, not the potential incompatibility of the materials, governs what can be stored together, making this combination acceptable under the standard procedures tested.
