An excavator operator has reviewed the 'Click Before You Dig' locates for a new trench. The locate marks indicate a high-voltage electrical line running parallel to the proposed trench, only 1.5 metres away from the edge of the planned excavation. What specific action, beyond standard safe digging practices, should the operator ensure is implemented?

Question: An excavator operator has reviewed the 'Click Before You Dig' locates for a new trench. The locate marks indicate a high-voltage electrical line running parallel to the proposed trench, only 1.5 metres away from the edge of the planned excavation. What specific action, beyond standard safe digging practices, should the operator ensure is implemented?

Answer options:

• Request the utility company to de-energize the line before starting work.
• Maintain a minimum clearance of 3.0 metres from the marked line with the excavator bucket. ✅ Implement a dedicated spotter whose only duty is to observe the electrical line and excavator's proximity.
• Install non-conductive barriers along the entire length of the electrical line.

Correct answer: Implement a dedicated spotter whose only duty is to observe the electrical line and excavator's proximity.

Explanation: When working in close proximity to critical utilities, especially high-voltage electrical lines, having a dedicated spotter is crucial for maintaining safe clearances and alerting the operator to potential hazards. While de-energizing is ideal, it's not always feasible or guaranteed, and 3.0 metres might not be the required safe limit depending on province/utility.
