The objective of these Guidelines is to support the Electricity Supply Industry in the development of appropriate safe working processes for aerial surveillance of Overhead Electricity Networks.
The principles within these Guidelines may be enhanced or supplemented provided this does not result in reduced safety standards.
These Guidelines are intended to:
(a) ensure the safety of pilot, monitor(s) and the general public;
(b) specify the minimum standards required for aerial surveillance of Overhead Electricity Networks; and
(c) assist Network Operators to develop work procedures and related training and awareness programs.

These Guidelines apply to aerial surveillance of Overhead Electricity Networks. They shall be applied in the context that:
Appropriate workplace hazard and risk assessments are carried out and documented.
The Minimum Separation Distances (MSD) and Maximum Work Distances (MWD) used for aerial surveillance are appropriate for the type of work to be performed. (Refer to Section 13).
Other Guidelines applicable to particular work processes are to be used.
While the principles of aerial surveillance of Overhead Electricity Networks contained in these Guidelines have been written in relation to work near overhead lines, the concepts may be equally applicable to work in other areas such as aerial surveillance of communication and control equipment, when combined with appropriate training and work controls.
These Guidelines do not constitute a training manual for aerial surveillance of Overhead Electricity Networks nor do they set down procedures for aerial surveillance of Overhead Electricity Networks. Procedures shall be developed by the Network Operator and/or Service Provider in accordance with the principles contained in these Guidelines.
These Guidelines exclude:
low voltage and high voltage line work; and
high voltage live line work.
