Question: An operator observes a continuous drip of diesel (approximately 1 litre per hour) from the engine of their grader onto the ground after parking it overnight. What is the most appropriate first action?

Answer options: ✅ Place an absorbent mat or drip tray under the leak point and immediately report it for repair.

• Wait to see if the leak stops on its own, as it might be residual fuel.
• Attempt to tighten the hose clamp causing the drip with a wrench from the onboard toolkit.
• Cover the small puddle with sawdust and continue using the grader for the shift.

Correct answer: Place an absorbent mat or drip tray under the leak point and immediately report it for repair.

Explanation: Even a small, continuous drip can lead to significant environmental contamination over time. The correct first action is to contain the immediate spill by placing absorbents and immediately report the issue for professional repair to prevent further leakage and environmental damage, as per CCOHS guidance.
