Question: A wheel loader operator is tasked with excavating a trench for a new water main. Before starting the work, what is the MOST critical action to take regarding potential underground utilities?

Answer options:

• Verify the soil type to determine appropriate excavation methods.
• Ensure all personal protective equipment (PPE) is being worn. ✅ Confirm that a 'locate' has been performed and documented through a provincial one-call centre or equivalent.
• Inspect the wheel loader for any mechanical defects or fluid leaks.

Correct answer: Confirm that a 'locate' has been performed and documented through a provincial one-call centre or equivalent.

Explanation: Provincial OHS regulations (e.g., OHSA R.R.O. 1990, Reg. 213/91 s. 228(1) in Ontario) and CCOHS guidance mandate that employers ensure the location of all underground services is accurately determined and marked before excavation work begins. Failure to do so poses severe safety risks.
