What should be done if time is short when an electrical storm approaches?

• A. Launch the blast immediately
• B. Clear the area and guard as for a blast
• C. Wait until the storm clears
• D. Disconnect all equipment

Answer: (B)

When an electrical storm approaches, prioritizing safety is crucial, especially in mining operations where explosive materials may be present. Clearing the area and guarding as if preparing for a blast ensures that personnel are adequately protected from the storm's hazards, such as lightning. This procedure minimizes the risk of injury or accidents that could arise from both the electrical storm and any explosive handling during this time.

By treating the situation with the same caution as if preparing for a blast, you ensure that all personnel are at a safe distance and that no unauthorized individuals are in the potentially hazardous area. It also allows for better management of the situation, as personnel can be instructed to assemble in designated safe zones, thus reducing chaos and ensuring everyone's safety.

Other options do not address the fundamental need for safety during such conditions. Launching a blast immediately or waiting until the storm clears could expose workers to danger from both the storm and mismanaged explosive materials. Disconnecting all equipment might not adequately protect personnel who are still in the area, and it could lead to operational risks if not managed correctly. Thus, the best course of action is to clear the area while preparing for the storm with the same caution as for a scheduled blast.
