Which category is NOT part of the safety responsibilities of a traffic signal technician?

Efficiency in work completion is focused on the timely and effective execution of tasks rather than directly addressing safety concerns. While completing work efficiently is certainly important in the role of a traffic signal technician, it does not fall under the umbrella of safety responsibilities.

In contrast, ensuring the safety of motorists and pedestrians is a primary concern, as traffic signals are critical for managing vehicle and foot traffic and preventing accidents. Personal safety is equally essential, as technicians work in various environments, including roadways and construction sites, where they must protect themselves from potential hazards. Lastly, the safety of public and personal property is also a critical responsibility, as technicians must ensure that their work does not pose risks to infrastructure or vehicles. These categories illustrate that safety is a multi-faceted concern that encompasses various aspects of the technician's role, while efficiency pertains more to performance and productivity metrics rather than safety itself.
