These Guidelines provide principles and responsibilities for control authorities and service providers for access to apparatus associated with the generation, transmission and distribution of electricity.
These Guidelines also detail the minimum general requirements for work to be carried out under access authorities. These Guidelines are not intended to cover specific requirements for other work such as welding and cutting, working at heights, mobile plant, confined spaces, excavation work or work on extra low voltage exposed conductors.
The application of approved live high voltage working techniques is not covered by these Guidelines.
