Power lines are always presumed to be what in crane safety guidelines?

• A. De-energized
• B. Energized
• C. Isolated
• D. Unknown

Answer: (B)

The key point is that power lines near crane operations must be treated as live at all times. Because lines can still be energized due to stored energy, weather effects, or re-energization, the safest approach is to assume they are energized until the utility has verified de-energization, locked out, and tested the circuit. This perspective drives essential safety practices, like maintaining the required clearance distances, using a spotter, and coordinating with the power company before moving the crane or lifting near lines. Saying the lines are de-energized or isolated would create a false sense of safety, and treating the status as unknown ignores the real hazard.
