AS 4568:2005 pdf – Preparation of a safety and operating plan for gas networks.
(d) communication/contact points for reporting of incidents:
(e) asset inspection patrols: and
(0 the integration of communication systems with those of third parties.
3.5.4 Sstem maintenance
The Plan should describe how, where network safet and/or reliability depends upon the function of specific components, the network operator ensures appropriate preventative maintenance programs are established to ensure the continued effective functioning of the corn ponents.
3.5.5 Change management
The Plan should describe how the management of changes (e.g.. technical, procedural and personnel) to safety processes and systems is achieved and should demonstrate the use of risk management principles to validate the effectiveness of the changes and to minimize any’ detrimental impact or consequences upon other systems.
3.5.6 Documented work practices
The Plan should describe, where network safety and reliability depends upon uniform or repeatable performance or defined work practices, how those work practices should be documented. The documentation should he to a level of detail that enables critical elements to he identified for communication and control.
3.5.7 Emergency response
The Plan should describe how the operator establishes and maintains an emergency plan for implementation in the event of facility failures, accidents or other emergencies. These plans should be developed in order to mitigate the consequences of the failure, accident or emergency.
All relevant operating and maintenance personnel should he competent and trained to carry out their responsibilities in the event of an emergency.
The emergency plan(s) should include the read mess of personnel, equipment materials and communication systems, access to necessary infi.rrnation. co-ordination with emergency services and organizations and liaison with customers and local communities.
Where appropriate, emergency event rehearsals and exercises (involving all relevant third parties) should be used fbr process validation, training and for maintaining readiness or response.
3.5.X 6as specification and characteristics
The Plan should describe how the network operator establishes and maintains a
specification for the quality composition of the gas to be distributed through the network.
and ensure its suitability for safe and reliable use in the proposed application/s.
4.1GENERAL
The Plan should describe how the network operator ensures that risk management is acontinuous process at all stages throughout the life cycle of a distribution network. Theprimary principle in managing risk is to achieve acceptable risk criteria and to reduce therisks to As Low As Reasonably Practicable (ALARP).
In order to identify the risks associated with the network,specifically potential high risks, aformal safety assessment shall be carried out.For each system or process identified by theformal safety assessment as critical to control the risk, the operator shall—
(a) identify those procedures,information links， skills and internal and external
authorities/responsibilities required for the system to operate effectively;
(b) provide the resources and arrangements required to maintain system readiness andeffectiveness; and
(c)utilize a process of monitoring and review of system performance to ensure that the
system continues to operate as designed.
