Induced voltage represents a significant hazard for qualified electrical workers primarily because it can occur unexpectedly and without any visible indication of danger, unlike re-energization which typically has clear warnings and procedures associated with it. Induced voltages can arise from various sources, such as electromagnetic fields, and can lead to unexpected shocks or electrical arcs, posing serious risks while performing tasks on or near energized equipment.

In contrast, re-energization usually occurs under controlled conditions where workers are aware of the risks and take necessary precautions. Therefore, while re-energization is indeed risky, the unpredictable nature of induced voltage elevates its hazard level, making it essential for workers to be thoroughly trained and aware of how to recognize and mitigate these dangers in the work environment.
