If operating near an energized powerline (but outside the prohibited area) is unavoidable, which step best ensures safe operation?

• A. A meeting must be held with the lift team discussing how to remain outside the prohibited zone.
• B. Non-conductive tag lines should be used.
• C. Erect a visual aid for the operator to use as a guide to remain outside the prohibited area. If the operator cannot see the visual aid, a spotter must be used.
• D. If a spotter must be used, at least one of the following must be used: An insulating link; A high-voltage proximity warning device; An automatic warning device that tells the operator to stop movement of the boom/load line; An automatic movement limiting device.

Answer: (C)

Keeping a clear, visible boundary around the energized powerline is essential for safe operation. Erecting a visual aid gives the operator an always-present, easy-to-see cue to stay outside the prohibited area, so distance is maintained consistently as the lift moves. This direct guidance helps the operator and any spotter coordinate real-time actions and prevents drift toward the line. If the operator cannot see the visual aid, bringing in a spotter ensures another set of eyes enforces the boundary and stops movement before the danger zone is reached. While other protections like tag lines or proximity devices can help, they don’t provide the same immediate, visible reminder and require extra equipment or conditions. The visual boundary with spotter support offers the most reliable, straightforward way to sustain safe clearance from the line.
