What safety measure is essential when working on different phases at the same time?

When working on different phases simultaneously, utilizing individual aerial lifts is crucial for ensuring safety. Aerial lifts provide a means to maintain a safe and stable platform for linemen to work at heights while being isolated from power lines. This isolation minimizes the risk of electrical shock and allows for safe access to all phases without having to come into close proximity with energized lines. Using separate lifts for each phase keeps linemen secure and prevents potential contact with dangerous voltages.

In contrast, other measures like gloves, while they are important for electrical work, do not provide the same level of safety as individual aerial lifts when working on different phases. Shifting phases may not effectively address the safety risks inherent in handling multiple energized lines at the same time, and time management, while valuable for efficiency, does not directly mitigate the hazards associated with the work environment. Thus, individual aerial lifts are recognized as a critical safety measure in this context.
