Why is direct supervision emphasized in the guidelines for working with secondary voltage?

Direct supervision is emphasized in the guidelines for working with secondary voltage primarily to minimize risk and ensure safety. Secondary voltage systems involve electrical work that can pose serious hazards, including electrical shock or fire, if not handled properly. By requiring direct supervision, experienced professionals can monitor and guide workers—particularly those who are less experienced or unfamiliar with specific safety protocols—thus reducing the chances of accidents or mishandling of equipment.

The presence of a supervisor ensures that safety practices are followed meticulously, enabling immediate assistance or intervention in case of an incident. This guidance is crucial in environments where electrical hazards are prevalent and where understanding the proper techniques for managing secondary voltage is essential for the protection of all individuals involved.

While other choices touch on important aspects of training and teamwork, they do not address the critical focus on safety that direct supervision ensures in potentially dangerous situations involving electricity.
