What action is required when lightning is detected within a five nautical mile radius for operations involving exposed EIDs?

• A. Proceed with normal precautions
• B. Pause operations and reassess after weather clears
• C. Proceed at reduced speed
• D. Operations cease and area vacated

Answer: (D)

Lightning poses a real initiation risk to exposed EIDs, so when it’s detected within five nautical miles, the only safe action is to stop operations and evacuate the area. This immediate, clear response removes everyone from the potential hazard zone and prevents any chance that a nearby strike or induced surge could trigger sensitive devices. Simply proceeding with precautions, slowing down, or pausing and reassessing still leaves personnel in a hazardous area and does not eliminate the risk. After the weather passes, a formal clearance and review are needed before resuming work, but the priority during a lightning threat is to vacate.
