Question: During excavation, a backhoe operator accidentally strikes an unmarked buried power cable, causing sparks and a power outage in the area. The operator feels a tingling sensation. What should be the operator's immediate course of action?

Answer options:

• Assume the machine is energized and, if safe to do so, jump clear of the machine ensuring both feet land together, then shuffle away. ✅ Stay in the cab, warn others to stay at a safe distance, and wait for emergency services to de-energize the line.
• Immediately move the machine away from the cable to prevent further damage.
• Contact the utility company directly to report the strike.

Correct answer: Stay in the cab, warn others to stay at a safe distance, and wait for emergency services to de-energize the line.

Explanation: Feeling a tingling sensation indicates the machine and ground around it are energized. The safest action is to stay in the cab, as exiting incorrectly can lead to electrocution. Warn others and wait for the power to be shut off. This is mandated by provincial OHS regulations.
