Where must signs for a No-Lone Zone be posted?

• A. At the base gate
• B. At internal entry control points of the zone
• C. On all doors of facilities
• D. On the exterior perimeter of the zone

Answer: (B)

A No-Lone Zone sign belongs at the internal entry control points of the zone. This is the moment and place where someone first enters the restricted area, so the reminder is most effective and unavoidable as personnel step inside. Placing signs at internal entry points ensures the rule is seen before anyone proceeds deeper, supporting the requirement to avoid leaving someone alone in the zone. Signs at the base gate, on every door, or only on the exterior perimeter don’t guarantee visibility at the actual entry where the rule applies, making this option the least reliable for enforcing the No-Lone Zone.
