Which of the following is NOT a recommended safety measure when working near energized lines?

• A. De-energize lines if possible
• B. Maintain clearance distances and use a spotter
• C. Assume lines are insulated and safe
• D. Follow regulatory requirements

Answer: (C)

The main idea is that you must treat lines near a crane as live hazards and use proven safety practices, not assumptions about insulation. De-energizing lines if possible removes the electrical danger entirely. Keeping safe clearance distances and having a spotter ensures you maintain the required space and have a dedicated observer to coordinate movements. Following regulatory requirements ensures you’re using established, tested procedures and protections.

Assuming lines are insulated and safe is not acceptable because insulation can be damaged, wear out, or fail, and energized lines can still arc or energize equipment even when they look insulated. Electricity doesn’t rely on appearance, so you must manage the hazard by de-energizing whenever feasible, maintaining proper clearances with a spotter, and adhering to regulatory rules.
