When is it critical to use a remote-operated motorized racking tool?

Using a remote-operated motorized racking tool is critical when distance from potential arcing faults is necessary. This situation arises when individuals are handling energized equipment where arcing can occur, presenting a significant risk to safety. By utilizing a remote-operated tool, personnel can operate the racking mechanism from a safe distance, mitigating the risks associated with electrical arcs and reducing the potential for electrical shock or injury.

The primary goal of implementing such tools is to ensure safety by maximizing the distance between workers and any potential hazards, particularly in environments where high voltage is present. This aligns with the principles outlined in NFPA 70E, which emphasizes the importance of maintaining safety measures to protect workers from electrical hazards. The other options may not fully address the critical safety implications during high-risk operations, underlining the specific importance of distance in the context of electrical safety in the workplace.
