In terms of safety, where is the best position for trolley wire regarding worker proximity?

The safest position for trolley wire in relation to worker proximity is at least 6 inches from the operational area. This distance is significant for ensuring that workers can safely perform their tasks without risk of accidental contact with the high-voltage trolley wire, which can pose severe electrical hazards. Maintaining this distance minimizes the likelihood of an electric shock or injury while allowing for safe movement and operations in the work area.

Being positioned directly above the worker's head, as suggested in another option, could lead to potential hazards if workers need to reach overhead or if equipment is operated in that area. Similarly, placing the trolley wire on the ground or at the same height as the rail increases the risk of contact with both the wire and moving equipment, creating dangerous situations for workers nearby. Thus, ensuring that the trolley wire remains a safe distance away is crucial for protecting personnel and facilitating a safe working environment.
