How should a worker ensure safety when working near conductors with a cluster bar and personal jumper?

Creating an equipotential zone is essential for ensuring safety when working near conductors, especially with the potential for electrical hazards. An equipotential zone is established when all conductive parts within a specific area are at the same electrical potential, minimizing the risk of electrical shock or arc flash. By ensuring that the worker and the conductors are at the same potential, the chance of a difference in voltage that could lead to a hazardous situation is significantly reduced. This practice is critical when dealing with live conductors, as it helps protect the worker from unexpected electrical surges and provides a safer work environment.

Other methods, while relevant to safety, do not address the specific electrical hazard present in this scenario as effectively. For instance, maintaining high visibility is important for general safety but does not mitigate electrical risks. Using insulated tools is critical; however, insulation alone does not eliminate the dangers of working near energized conductors. Staying within arm's reach of equipment may help in terms of accessibility or tool management but does not enhance safety against electrical hazards. Therefore, establishing an equipotential zone is the most effective and crucial step in this context for ensuring worker safety.
