Knowledge evolves over time as research and development yields operational enhancements to process facilities. ISA-TR84.00.04-1 Annex R provides examples of key performance indicators that can be used to monitor aspects of the SIS lifecycle. Events involving abnormal operation may identify weaknesses in the risk-reduction strategy, leading to the need for more safeguards and improved performance metrics. New ideas identify ways to lower risk further. [Pg.28]

Update documents to as-built status, incorporating changes made since the last formal drawing/document revision. Maintain documentation under revision control for the life of the equipment. Documentation should be traceable to the process hazard analysis and should be auditable. [Pg.28]
