3 Check customer s file regarding current transformer (CT) / voltage transformer (VT) information, meter type, etc. Failure to notify affected consumers: public risk reliance on supply for health, safety and medical reasons required to eliminate or minimise the risk of Notify affected consumers if outage required Communicate with land owner/customer to determine safe entry requirements (if required) Ensure authorisation from consumer to shutdown supply if identified as a life support / sensitive load consumer Traffic management (if required) Vehicles, pedestrians, unauthorised access: Confirm that an accredited traffic management company has been engaged (if required) Control pedestrian and vehicle interface Keep pedestrians and vehicles apart, Control vehicle movements on site and when vehicles enter and exit the workplace inimise vehicle movements anage the risks of reversing vehicles Vehicle and equipment movement: impact,, property damage Unauthorised access: Ensure suitable traffic and pedestrian management arrangements are in place. 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 b. reversing vehicles c. persons are on the ground and in proximity to moving vehicles and d. in other situations as indicated by a risk assessment. Ensure visual (flashing lights) warning devices, reversing alarms and high-visibility markings for powered mobile plant are operational prior to commencing work. Workplace set up Confirm correct location / apparatus Advise Project anager / Site Foreman Conduct risk assessment include all staff Contact with live electrical apparatus: shock, Electrical apparatus failure: shock, Asbestos or fibreglass material: harm Restricted space: sprain, cramp, fatigue Confirm correct location, apparatus, service order details Communicate with land owner / consumer to determine safe entry requirements (if required) Use up-to-date maps and drawings (if required) 3.2, 3.3, 3.9, 3.10, 4, 5.7, 6, 7, 11.1 WP sections: 2.1, 2.2, 2.4, 2.6, 2.7, 2.8, 2.12, Western Power Safe Work ethod Statement igh Voltage (V) etering Installation Commissioning page 3 of 5
