Methods for protecting employees and others from electrical hazards adjacent to electric utility vehicles

Electrical hazards related to electric utility vehicles working adjacent to a power line are generated from two sources: from induction due to the proximity of the vehicle to energized facilities, or an accidental contact between the vehicle and energized parts. The magnitude of the current and voltages, and thus the related hazards are quite different. Methods of minimizing the hazard and are discussed in the paper. Isolating the work site by barricading is the best method for protecting the public. Complete isolation is not practical for the worker. Grounding the vehicle will reduce the vehicle voltage but the resulting current flow will create step and touch hazards. Isolation from the grounding points and limitation of the time a work has contact with the vehicle are very desirable methods of protection
