Which of the following lists the four Emergency Classification Levels?

• A. Notification of Unusual Event; Alert; Site Area Emergency; General Emergency
• B. Unusual Event; Alert; Alert; General Emergency
• C. Site Area Emergency; General Emergency; Emergency Signal; Alarm
• D. Notification of Unusual Event; Site Area Emergency; General Emergency; Alert

Answer: (A)

These items test how you recall the four Emergency Classification Levels used for plant emergencies, arranged from least to most severe. The four levels, in the correct sequence, are Notification of Unusual Event, Alert, Site Area Emergency, and General Emergency. Each level signals a deeper level of potential or actual safety concern and drives specific protective actions and notifications.

Why this is the best choice: it lists exactly these four levels in the proper order, which is the standard progression used to guide responses and communications during emergencies. The other options mix in terms that aren’t classification levels (like Emergency Signal or Alarm), duplicate a level, or place the levels out of order, which wouldn’t align with the established response framework.
