Question: Upon noticing smoke or flames emanating from the engine compartment of a wheel loader during operation, what is the operator's primary course of action?

Answer options:

• Continue operating to move the loader to a safe, open area before addressing the fire. ✅ Immediately activate the machine's fire suppression system (if equipped), then shut down the engine and exit the cab.
• Retrieve a portable fire extinguisher from the cab and attempt to suppress the fire.
• Request assistance via radio and wait for emergency services to arrive before taking further action.

Correct answer: Immediately activate the machine's fire suppression system (if equipped), then shut down the engine and exit the cab.

Explanation: The primary action is to activate any onboard fire suppression system. Then, safely shut down the engine and exit the machine, moving to a safe distance. Attempting to fight a large engine fire with a portable extinguisher can be dangerous and ineffective.
