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.
Contents: Introduction, Qualitative Methods of Risk Assessment, Quantitative Methods of Risk Assessment-I: Consequence Analysis, Quantitative Methods of Risk Assessment-II: Rapid Risk Assessment, Quantitative Methods of Risk Assessment-III: Probabilistic Hazard Assessment, Studies on Chain, of Accidents (Domino Effects), Methods of Hazard Identification, Screening and Ranking, Application of Risk Analysis in Process Design.
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.
Papers presented in this work reflect the need for everyone involved in the process industries to understand the demands of COMAH regulations. They include contributions on: COMAH - an HSE view and application; chemical and reaction hazards; risk assessment and simulation techniques.
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.
The tragic incident at Bhopal, India made it clear that safetyreviews for identification and control of accidents involving toxicchemicals must be more systematic. This guide shows how tointegrate hazard identification, risk assessment, consequenceanalysis, and risk mitigation into a formalized program forhandling hazardous chemicals. Most of the 21 contributors aresenior staff members at Stone & Webster EngineeringCorporation. They discuss how to perform and supervise safetystudies for chemical, petrochemical, petroleum refining, and otherfacilities. They discuss all aspects of detection, prevention, andmitigation of risks associated with processing, handling, andproduction of hazardous chemicals. Special attention is given tohazard identification and hazard assessment techniques ranging fromsimple screening checklists to highly structured Hazard andOperability (HAZOP) analysis. You're shown how to calculatepotential consequences of identified hazards, quantify thelikelihood of these events, and combine equipment failure rate dataand human reliability analysis with hazard assessment. You'll alsobenefit from the book's rundowns of how to * apply expert systems and artificial intelligence in riskmanagement * instill safety-oriented operating and maintenanceprocedures * train operators and emergency response personnel * conduct internal and external safety audits * perform chemical dispersion, explosion, and fire analyses * assess health effects from chemical releases * use insurance vehicles to deal with residual risk. Risk Assessment and Risk Management for the Chemical ProcessIndustry is an essential source on minimizing the dangers of toxicincidents and accidents. It is essential reading for safetyengineers, regulatory managers, environmental engineers, and otherprofessionals responsible for safety in chemical plants.
