It must be assumed that power lines are:

When working near power lines, it is crucial to assume that they are energized. This assumption is vital for ensuring safety in the workplace, especially in activities involving cranes or other equipment that could inadvertently come into contact with the lines. Assuming power lines are energized helps workers maintain a cautious and respectful distance, avoiding the potential for electrical shocks, injuries, or fatalities that could occur if a line is inadvertently contacted.

Energized lines can carry a high voltage that poses significant danger, and taking this assumption into account prompts adherence to safety protocols, such as maintaining proper clearances and utilizing spotters or flaggers when operating equipment near these hazards. Always treating power lines as energized emphasizes the importance of planning and training to prevent accidents.
