The book is a guide for Layers of Protection Analysis (LOPA)practitioners.   It explains the onion skin modeland in particular, how it relates to the use of LOPA and the needfor non-safety instrumented independent protection layers. Itprovides specific guidance on Independent Protection Layers (IPLs)that are not Safety Instrumented Systems (SIS).  Using theLOPA methodology, companies typically take credit for riskreductions accomplished through non-SIS alternatives; i.e.administrative procedures, equipment design, etc.   Itaddresses issues such as how to ensure the effectiveness andmaintain reliability for administrative controls orinherently safer, passive concepts. This book will address how the fields of Human ReliabilityAnalysis, Fault Tree Analysis, Inherent Safety, Audits andAssessments, Maintenance, and Emergency Response relate to LOPA andSIS. The book will separate IPLs into categories such as thefollowing:Inherent Safety eliminates a scenario or fundamentally reduces a hazardPreventive/Proactive prevents initiating event from occurring such as enhancedmaintenancePreventive/Active stops chain of events after initiating event occurs but beforean incident has occurred such as high level in a tank shutting offthe pump.Mitigation (active or passive) minimizes impact once an incident has occurred such as closingblock valves once LEL is detected in the dike (active) or the dikepreventing contamination of groundwater (passive).
