How can energized parts that are not enclosed be guarded?

Guarding energized parts that are not enclosed is crucial in ensuring safety and preventing accidental contact. Utilizing substantial partitions or screens effectively separates these hazardous components from personnel, significantly minimizing the risk of accidental exposure to electrical hazards. This method provides a physical barrier, which is a recommended practice within safety standards.

While alarms and signage can serve as additional measures to alert individuals of potential danger, they do not provide a physical barrier like partitions or screens do. Similarly, maintaining a safe distance is a good practice, but it cannot always be reliably maintained, especially in areas where personnel may need to work or interact with equipment. Therefore, substantial partitions or screens represent the most effective approach to guard against the risks posed by unprotected energized parts, aligning with NEC code guidelines and safety standards.
