HAZOP: Guide to Best Practice, 3rd Edition describes and illustrates the HAZOP study method, highlighting a variety of proven uses and approaches. This updated edition brings additional experience with which to assist the reader in delivering optimum safety and efficiency of performance of the HAZOP team. HAZOP is the most widely-used technique in the process industries for the identification of hazards and the planning of safety measures. This book explains how to implement HAZOP techniques in new facilities and apply it to existing facilities. The content covers many of the possible applications of HAZOP and takes you through all the stages of a study. This simple, easily digestible book is a favorite in the chemical and process industries. - A concise and clear guide to the do's and don'ts in HAZOP - New edition brings additional experience to help you deliver optimum safety and efficiency of performance. - Updated material includes a section on HAZOP study of a procedure with a detailed example, new sections on pre-meeting with the client auditing a study, human factors and linking HAZOP study to LOPA. A section on start-up and shutdown has been added to the chapter on specific applications of HAZOP.

These guidelines are intended to provide guidance on a specific technique developed for use in the chemical and process industries. This technique is HAZOP study - a detailed method for systematic examination of a well-defined process or operation, either planned or existing. ICI developed the HAZOP study method in the '60s and the CIA guide, published in 1977 encouraged development. Since then it has become, for many, the choice technique for hazard identification in new designs, processes and operations.

Hazop and Hazan were developed to identify and assess hazards in the process industries. The use of these techniques leads to safer plants. Understanding the practical issues involved in their correct implementation is the theme of this book.

This revised edition provides the basics of applying hazard and operability study (Hazop) and hazard analysis (Hazan). Hazop is a creative but systematic method of identifying hazards in process plants. Hazard analysis is then used to quantify the risks from these hazards, and to assess how far to go in reducing them. This book is presented in easy-to-read style and explains: what a Hazop is, who carries it out, when, and how long it should take; points to watch during a Hazop; an example of a Hazop; Hazops on flowsheets; the stages of Hazard analysis; the Fatal Accident Rate; risks to the public; estimating how often an accident will occur, with examples; and pitfalls in Hazan.

This unique manual is a comprehensive, easy-to-read overview of hazards analysis as it applies to the process and allied industries. The book begins by building a background in the technical definition of risk, past industrial incidents and their impacts, ensuing legislation, and the language and terms of the risk field. It addresses the different types of structured analytical techniques for conducting Process Hazards Analyses (PHA), provides a "What If" checklist, and shows how to organize and set up PHA sessions. Other topics include layout and siting considerations, Failure Modes and Effect Analysis (FMEA), human factors, loss of containment, and PHA team leadership issues.

This book provides, as simply as possible, sound foundations for an in-depth understanding of reliability engineering with regard to qualitative analysis, modelling, and probabilistic calculations of safety and production systems. Drawing on the authors’ extensive experience within the field of reliability engineering, it addresses and discusses a variety of topics, including: • Background and overview of safety and dependability studies; • Explanation and critical analysis of definitions related to core concepts; • Risk identification through qualitative approaches (preliminary hazard analysis, HAZOP, FMECA, etc.); • Modelling of industrial systems through static (fault tree, reliability block diagram), sequential (cause-consequence diagrams, event trees, LOPA, bowtie), and dynamic (Markov graphs, Petri nets) approaches; • Probabilistic calculations through state-of-the-art analytical or Monte Carlo simulation techniques; • Analysis, modelling, and calculations of common cause failure and uncertainties; • Linkages and combinations between the various modelling and calculation approaches; • Reliability data collection and standardization. The book features illustrations, explanations, examples, and exercises to help readers gain a detailed understanding of the topic and implement it into their own work. Further, it analyses the production availability of production systems and the functional safety of safety systems (SIL calculations), showcasing specific applications of the general theory discussed. Given its scope, this book is a valuable resource for engineers, software designers, standard developers, professors, and students.
