What classification of fuel leak does the loader have?

• A. Class 0
• B. Class 1
• C. Class 2
• D. Class 3

Answer: (B)

Fuel leak classifications indicate how serious a leak is and what action is needed. A small, slow seepage with little or no pooling that can be contained and repaired without an immediate fire hazard fits Class 1. It signals a fault to fix soon—like tightening a connection or replacing a hose—while not requiring the urgent shutdown or containment steps of higher classes. No leak would be Class 0, a larger pool or continuous dripping would be Class 2, and an active spray or large hazardous release would be Class 3. So, a minor fuel seepage on the loader is best described as Class 1.
