Question: During a pre-shift inspection, an operator notices a 20 mm (0.8 in.) deep cut on the sidewall of a wheel loader tire. What is the appropriate action to take?

Answer options: ✅ Immediately report it to a supervisor and cease operating the machine until the tire is repaired or replaced.

• Monitor it closely during the shift and report it at the end of the day.
• Fill the cut with a temporary sealant and continue operating.
• Reduce the tire pressure to relieve stress on the cut.

Correct answer: Immediately report it to a supervisor and cease operating the machine until the tire is repaired or replaced.

Explanation: Any significant damage to a tire, especially a deep sidewall cut, compromises its structural integrity and poses an immediate safety risk. Operating with such damage can lead to a blowout, which can cause serious injury or damage. Alberta OHS Code Part 14 emphasizes the importance of inspecting mobile equipment for safe operation.
