The book has two parts; one part is mainly related to hazard analysis methods applicable for all disciplines of engineering. The other part is based around recent IEC standards for life cycle analysis for safety instrumented systems (SISs). The book covers all major hazard analysis methods and safety instrumentation applicable for all industrial plants. The book enjoys granted permission from IEC Switzerland to utilize some figures from their standards IEC 61508 and 61511; the premier international standards for E/E/PEs for SIS and life cycle methods (duly acknowledged). In view of the total coverage of the book, international society IChemE has included the book in their series of technical books.

There are a number of books available on hazard analysis as well as quite a few books on SIS. However, there are hardly any technical books where people get the tastes of both in a single book. Also, the majority books are with theoretical approach with huge mathematical details, or only practical details without any basic approach. This book endeavors to act as a balancing means between two extreme lines of thinking, giving a comprehensive approach toward hazard analysis as well as safety instrumented systems. The book takes into account basic mathematics, but more emphasis has been put on physical explanations. Hazard analysis covers both qualitative type, word-based systems, and quantitative systems (including human errors analysis) have also been covered comprehensively with automated processes for hazard analyses. Hazard analysis part will help instrumentation practicing engineers in participating in various hazard analysis processes. For each case, both mathematical approaches as well as physical explanations have been put forward. Step-by-step SIS determination from various failure modes, reliability, and safety integrity level (SIL) calculations and selections from various approaches, for example, risk matrix, risk graph, etc. help to arrive at correct and appropriate SIL calculation. The book comprehensively discusses each and every stage in different phases, that is, all the aspects of life cycle process mentioned in IEC 61508 and 61511 for E/E/PEs, with respect to continuous process and manufacturing industries. The book also covers safety systems of batch process in line with ISA 88. It also includes an alarm as an independent protection layer (IPL), area classification including explosion protection, fire and gas system, process shutdown (PSD) and emergency shutdown (ESD). Finally, a discussion on SIS would be incomplete unless certification methods, FMEDA, proof testing, and partial stroke testing, etc. are not covered.

Detailed discussions at component level starting from sensors, safety field bus, safe logic solvers, and final control elements are a unique addition to the book. The book also covers the security aspects of various networks, viz. firewalls and zone-conduit to name a few, which is also another unique feature of the book. The book also covers application of SIS in various plants covering fossil fuel power stations, nuclear power stations, oil and gas sector such as upstream, midstream, refinery, and petrochemicals. There have been supplementary data and information on statistical approaches, embedded controls, and cost impact and life cycle cost analysis to take care of advancement in technology and systematic approach toward the problem.

The book is primarily meant for working professionals but budding (fresh) engineers who started their career in industrial plants and process plants will be equally benefitted. The book covers both hazard analysis and safety instrumentation from early stage to most advanced stage. It would be beneficial to engineers from other disciplines also in almost all industrial sectors – with special reference to process industries. For this comprehensive coverage, the book has been selected by IChemE in their series of technical books.
