What precautions should be taken if an electrical storm approaches a loaded blast hole pattern?

• A. Clear the area around the hole
• B. Only guard the area if the storm is severe
• C. Remove surface relays if time permits
• D. Both clear the area and remove surface relays if time permits

Answer: (D)

In situations where an electrical storm is approaching a loaded blast hole pattern, it's crucial to prioritize safety due to the risks associated with lightning and other storm-related hazards. Clearing the area around the hole ensures that personnel are kept at a safe distance from the potential danger of an accidental detonation triggered by lightning. The act of removing surface relays, if time allows, adds another layer of precaution by eliminating possible paths for inadvertent electrical charges that could lead to an explosion.

Combining both actions—clearing the area and removing surface relays—creates a comprehensive safety strategy. By doing so, the risks associated with the combination of a storm and the presence of explosives are significantly minimized, thereby safeguarding personnel and the environment.

While it may be important to monitor the severity of the storm, the recommended actions are proactive measures aimed at ensuring safety before any critical situation escalates. Unlike other options that suggest less comprehensive actions, the correct choice encompasses a complete response to the potential threat posed by an approaching electrical storm.
