Which of the following can be stored with other explosives?

• A. Electric caps which have the lead wires shunted.
• B. Capped safety fuse.
• C. Primacord.
• D. None of the above.

Answer: (C)

Primacord, known as detonating cord, can be stored with other explosives because it is designed to be a safe and reliable means of initiating detonations and can be handled in proximity to other explosive materials under controlled conditions. Detonating cord, when handled properly, does not pose a significant risk of accidental detonation when stored alongside compatible explosives, as it is typically designed to carry a shock wave rather than initiate an explosion on its own.

Conversely, electric caps that have the lead wires shunted and capped safety fuses are generally considered to have a higher risk of accidental initiation due to their design and sensitivity. Electric caps, even when shunted, can still pose a danger if exposed to certain conditions. Similarly, capped safety fuses may contain components that make them more sensitive to shock or heat, increasing the risk of unintended ignition when stored with other explosives. Therefore, those options are less suitable for storage with other explosive materials.
