The Code provides, for gas industry network operators, a basis for the development of a Safety and Operating Plan, (or Safety Case), referred to as a Plan. It describes the fundamental elements to be addressed in the preparation of a Plan (or Undertaking) by a distribution network operator, for the safe and reliable operation of new and/or existing gas reticulation networks supplying fuel gases suitable for domestic, commercial or industrial utilisation. The extent of application of these fundamental elements is a matter of judgement according to the operational issues. The Code does not address a Plan for systems covered by AS 5601 / AG 601 Gas installations. The Code is directed primarily at the Plan, which would in turn refer to other documents for supporting details and practices. AG 603 - Gas Network Management describes the management and operation of a gas network. The relevant design and construction standards i.e. AS 1697, AS 3723 and other appropriate national, industry and company standards would be referenced in other documents according to the adopted framework.
