What does the Restricted Approach Boundary refer to?

The Restricted Approach Boundary defines a specific distance from energized electrical conductors or parts where the risk of electric shock due to arc-over increases significantly. This boundary serves as a critical safety measure in electrical work environments to protect workers from the dangers associated with electric shock. Within this zone, personnel must exercise heightened caution and implement specific safety protocols because the potential for a hazardous event, such as an electric arc flash or contact with live parts, is elevated.

Understanding the Restricted Approach Boundary is essential for ensuring that individuals working near energized systems do so with the proper precautions. It emphasizes the importance of using appropriate personal protective equipment and adhering to established safety guidelines when working near potential electrical hazards. This boundary is a crucial element of the overall strategy to reduce workplace electrical risks and to help ensure the safety of all personnel involved.
