Question: During a pre-shift inspection, an excavator operator notices water seeping out of the cut face of a trench and small rocks beginning to dislodge. The trench is 3.5 metres deep. What is the immediate and most appropriate action?

Answer options: ✅ Immediately evacuate the trench and report the unstable conditions to the supervisor.

• Continue working, but monitor the situation closely for any further changes.
• Attempt to stabilize the area by placing large rocks at the base of the seepage.
• Install additional shoring in the affected area before continuing work.

Correct answer: Immediately evacuate the trench and report the unstable conditions to the supervisor.

Explanation: Water seepage and dislodging rocks are clear indicators of imminent trench failure due to soil saturation and instability. OHSA regulations require immediate evacuation and reporting of such hazardous conditions to prevent collapse, as attempting to work or stabilize from within puts workers at extreme risk.
