What should be used to avoid contact with energized lines?

The appropriate method to avoid contact with energized lines is to use insulating material, insulate equipment, or maintain a safe distance from the energized lines. This approach is essential for ensuring safety in environments where electrical hazards exist. Insulating materials and equipment serve to prevent electrical current from passing through unintended pathways, thus protecting workers from shock or electrical burns.

Additionally, keeping equipment at a safe distance helps to minimize risks associated with unexpected electrical arcs or flashovers that could occur if equipment were to inadvertently come too close to live conductors. Effective distance maintenance, along with appropriate insulating practices, creates a safe working environment around energized electrical systems. Other options, while useful in specific contexts, do not directly address the fundamental need to maintain safe distances and insulation from energized lines.
