3 Steps to Define Your Safety Critical Equipment (SCE) Define your Barriers / Categories and OwnersMaintenance / Reporting StrategyInitial Identification of SCEsReview with Technical Authorities, Safety Engineering, Independent VerifierFinalize your SCEs (30-50% of your asset register)
7 What is my SCE Maintenance / Reporting Strategy Fire and Gas Detection – Loop LevelPipeline Isolation – Valve or Item LevelUPS – Battery or Item LevelPressure Vessels – Item LevelEmergency Lighting – Loop or Area Level
9 Must Start with a Good Asset Structure What are my SCEs?Must Start with a Good Asset StructureFire and Gas Detection:Detectors – Gas, Flame, Heat, Etc.Defined / Maintained by Platform/Vessel, Deck, Zone, Loop, Area, Item?How are these defined? EX Equipment, Structures (TS,SS), Lifeboats, Emergency Lighting, ESD
10 Performance Standards Definition – Documentation of the specific measureable targets of an SCE to assure it is available and functioning to prevent or mitigate a Major AccidentDesign Vs Measurable?The Escape Route will be 1 meter wideThe Escape Route will be free of obstruction
11 Performance Standards should be: Understandable and Measurable Technicians need to be able to pick up a PS and understand exactly what they are required to do.The Assurance Activities should be measurable with either a Y/N or with a calculative response.valve closes <30 secondsGas Detector alarms at >10 PPMEmergency Lighting works? Y/N
