This Standard describes the requirements to be applied by all rail organisations to ensure that safety risks associated with changes to railway operations, assets, or systems are identified and eliminated or reduced so far as is reasonably practicable (SFAIRP). Management of change (MOC) is a methodology that is used as part of the risk assessment and control process. This Standard outlines the key actions under the MOC methodology along with a number of matters that should be considered as part of the MOC process. This Standard applies to all organisations who are responsible for safety under the Rail Safety National Law (RSNL) Act and Regulations. Specifically, there is a requirement under the RSNL Regulations Schedule 1 clause 12. For the purpose of this Standard and to be consistent with the RSNL, all organisations are referred to as rail transport operators (RTO).
