Question: A dozer operator notices a burning smell and smoke emerging from the undercarriage. There are no flames visible yet. What is the recommended procedure?

Answer options: ✅ Park the machine in a clear area, shut down the engine, and investigate the source of the smoke carefully with a fire extinguisher ready.

• Accelerate and drive quickly to the designated maintenance shop for inspection.
• Inform the supervisor and continue operating until the smoke dissipates.
• Spray water onto the undercarriage to cool it down, if available.

Correct answer: Park the machine in a clear area, shut down the engine, and investigate the source of the smoke carefully with a fire extinguisher ready.

Explanation: Any sign of smoke or burning smell requires immediate investigation in a safe manner; parking and shutting down isolates potential fuel/ignition sources, as per IUOE 793 guidelines on equipment monitoring and early fire response.
