• A. 5
• B. 10
• C. 15
• D. 20

Answer: (A)

Lightning Warning is about danger from a nearby storm, not distant weather. When lightning is within a very close radius of the installation, the risk to personnel and exposed equipment increases rapidly, so immediate protective actions are required. This near-zone threshold is set so you act quickly—pause or stop open-air operations, move people to shelter, and secure or shield sensitive gear—before a strike or arcing could occur. The idea is to err on the side of safety; warnings issued only when lightning is very close prevent waiting until the storm is farther away, which would leave less time to react. If the lightning is farther out, other weather advisories might cover it, but the Lightning Warning specifically triggers at the near-distance to maximize protection.
