Which hazard severity category has the highest potential loss?

Which hazard severity category has the highest potential loss?

• A. Catastrophic (Class A)
• B. Negligible (Class D)
• C. Moderate (Class C)
• D. Critical (Class B)

Answer: (D)

Hazard severity scales rank potential losses from negligible to catastrophic to help prioritize risk controls. The category with the greatest potential loss is Catastrophic, which covers the worst outcomes such as loss of life or permanent disability, mission incapacity on a large scale, or irreversible environmental or economic damage. That level drives the most urgent mitigation actions because the consequences are the most severe. The categories that follow—Critical, Moderate, and Negligible—represent progressively lower losses, so they do not represent the highest potential impact. If your course materials use a different labeling for the top category, the underlying idea remains: Catastrophic is the most severe level and the one with the highest potential loss.
