This will involve the development and implementation of a traffic and pedestrian management plan by a competent authorised Western Power representative. Provide separate clearly marked pedestrian walkways that take a direct route where possible. If the walkway crosses a roadway, provide a clearly signed and crossing point where drivers and pedestrians can see each other clearly. Before exiting the work zone ensure both vehicle and pedestrian traffic can be clearly seen in both directions. Keep walkways clear to avoid pedestrians having to step onto the vehicle route. Designate parking areas for workers and visitors vehicles outside the work zone. Appoint a vehicle spotter when: a. vehicles or plant are operating in close proximity to each other Western Power Safe Work ethod Statement Replace Overhead Consumer Service Core at SWER ine Transformer page 2 of 5
