In the three-level airfield risk system, which term represents the lowest level?

• A. Low
• B. Moderate
• C. Significant
• D. Critical

Answer: (A)

In an airfield safety framework, risk levels describe how serious a hazard is and what actions are needed. The lowest level means the hazard poses minimal risk to people and operations, so routine safety practices and standard monitoring are enough. In this kind of scale, terms typically move from Low to higher levels like Moderate, Significant, and Critical, with each step signaling greater likelihood or consequence. Since Low represents the smallest risk, it is the correct choice for the lowest level. The other terms describe progressively higher risk and would not be the baseline.
