Two-Person violation can be declared when a lone individual in a No-Lone Zone had opportunity to perform an incorrect or unauthorized act.

Two-Person violation can be declared when a lone individual in a No-Lone Zone had opportunity to perform an incorrect or unauthorized act.

• A. Not specified
• B. False
• C. True
• D. Only during drills

Answer: (C)

The main idea here is two-person integrity combined with a No-Lone Zone. In nuclear surety practice, two-person integrity means sensitive actions must always involve two authorized individuals present. A No-Lone Zone enforces that no single person can be alone with equipment or in certain areas. If a lone individual is in a No-Lone Zone and has the opportunity to perform an incorrect or unauthorized act, this indicates a lapse in the two-person controls. Even if no real unauthorized act occurs, the mere opportunity shows that the two-person protection could be bypassed, which is enough to declare a two-person violation. The rule is about maintaining two-person presence to prevent errors or misuse, not about whether a mistake actually happens. This isn’t limited to drills; the requirement applies whenever the zone rule is in effect. So a situation where solo presence could lead to an improper action is a violation, regardless of whether the act is carried out.
