What kind of equipment should be returned to the magazine in storm conditions?

• A. Blasting caps
• B. Surface relays
• C. Detonators
• D. Sound signals

Answer: (B)

In storm conditions, the primary concern is ensuring safety and preventing any potential hazards associated with explosive materials. Surface relays, which are not considered explosive themselves, can potentially be returned to the magazine to minimize risks during adverse weather conditions. This practice helps to keep sensitive equipment secure and away from the elements, thereby ensuring the safety of personnel and the integrity of the equipment.

In contrast, blasting caps and detonators fall under the category of explosive materials and require handling procedures that might be different due to the immediate risks they pose. Sound signals, while important for communication during mining operations, do not hold the same safety concerns associated with storm conditions as explosive materials do. Thus, returning surface relays rather than the more dangerous explosive items aligns with safety protocols in the presence of unpredictable weather.
