Download and read online ebook Guidelines for Initiating Events and Independent Protection Layers in Layer of Protection Analysis write by CCPS (Center for Chemical Process Safety). This book was released on 2014-12-31. Guidelines for Initiating Events and Independent Protection Layers in Layer of Protection Analysis available in PDF, EPUB and Kindle. The book is a guide for Layers of Protection Analysis (LOPA) practitioners. It explains the onion skin model and in particular, how it relates to the use of LOPA and the need for non-safety instrumented independent protection layers. It provides specific guidance on Independent Protection Layers (IPLs) that are not Safety Instrumented Systems (SIS). Using the LOPA methodology, companies typically take credit for risk reductions accomplished through non-SIS alternatives; i.e. administrative procedures, equipment design, etc. It addresses issues such as how to ensure the effectiveness and maintain reliability for administrative controls or “inherently safer, passive” concepts. This book will address how the fields of Human Reliability Analysis, Fault Tree Analysis, Inherent Safety, Audits and Assessments, Maintenance, and Emergency Response relate to LOPA and SIS. The book will separate IPL’s into categories such as the following: Inherent Safety eliminates a scenario or fundamentally reduces a hazard Preventive/Proactive prevents initiating event from occurring such as enhanced maintenance Preventive/Active stops chain of events after initiating event occurs but before an incident has occurred such as high level in a tank shutting off the pump. Mitigation (active or passive) minimizes impact once an incident has occurred such as closing block valves once LEL is detected in the dike (active) or the dike preventing contamination of groundwater (passive).

This book was released on 2013-11-18. Guidelines for Enabling Conditions and Conditional Modifiers in Layer of Protection Analysis available in PDF, EPUB and Kindle. The initial Layer of protection analysis (LOPA) book published in 2001 set the rules and approaches for using LOPA as an intermediate method between purely qualitative hazards evaluation/analysis and more quantitative analysis methods. Basic LOPA provides an order-of-magnitude risk estimate of risk with fairly reproducible results. LOPA results are considered critical in determining safety integrity level for design of safety instrumented systems. This guideline clarifies key concepts and reinforces the limitations and the requirements of LOPA. The main scope of the guideline is to provide examples of CMs and ECs and to provide concrete guidance on the protocols that must be followed to use these concepts. The book presents a brief overview of Layer of Protection Analysis (LOPA) and its variations, and summarizes terminology used for evaluating scenarios in the context of a typical incident sequence. It defines and illustrates the most common types of ECs and CMs and shows how they interrelate to risk criteria as well as their application to other methods.
Guidelines for Revalidating a Process Hazard Analysis

Download and read online ebook Guidelines for Revalidating a Process Hazard Analysis write by CCPS (Center for Chemical Process Safety). This book was released on 2022-10-21. Guidelines for Revalidating a Process Hazard Analysis available in PDF, EPUB and Kindle. GUIDELINES FOR REVALIDATING A PROCESS HAZARD ANALYSIS This book is derived from the experience of many companies in the chemical and hydrocarbon processing industries, and presents demonstrated, concise, and common sense approaches for a resource-effective revalidation of process hazard analyses (PHAs). It includes flowcharts, checklists, and worksheets that provide invaluable assistance to the revalidation process. The new edition, now as a guideline, provides a compete and thorough update of the first book and will provide much needed and requested guidance on PHA Revalidations including evaluating Prior PHA Studies, Identifying an Appropriate Revalidation Methodology, Preparing and Conducting the Revalidation Study Sessions, and Documenting the Revalidation Study.

Download and read online ebook Guidelines for Preventing Human Error in Process Safety write by CCPS (Center for Chemical Process Safety). This book was released on 2010-08-13. Guidelines for Preventing Human Error in Process Safety available in PDF, EPUB and Kindle. Almost all the major accident investigations--Texas City, Piper Alpha, the Phillips 66 explosion, Feyzin, Mexico City--show human error as the principal cause, either in design, operations, maintenance, or the management of safety. This book provides practical advice that can substantially reduce human error at all levels. In eight chapters--packed with case studies and examples of simple and advanced techniques for new and existing systems--the book challenges the assumption that human error is "unavoidable." Instead, it suggests a systems perspective. This view sees error as a consequence of a mismatch between human capabilities and demands and inappropriate organizational culture. This makes error a manageable factor and, therefore, avoidable.
Guidelines for Safe and Reliable Instrumented Protective Systems

Download and read online ebook Guidelines for Safe and Reliable Instrumented Protective Systems write by CCPS (Center for Chemical Process Safety). This book was released on 2011-11-16. Guidelines for Safe and Reliable Instrumented Protective Systems available in PDF, EPUB and Kindle. This book explains the decision-making processes for the management of instrumented protective systems (IPS) throughout a project's life cycle. It uses the new IEC 61511 standard as a basis for the work processes used to achieve safe and reliable process operation. By walking the reader through a project's life cycle, engineering, maintenance, and operations, the information allows users to easily focus on their responsibilities and duties. Using this approach, the book is useful as a primer, guidelines reference, and resource manual. Examples provide the added "real-world" experience applications.
