Comprehensive in scope, it describes the process of system safety--from the creation and management of a safety program on a system under development to the analysis that must be performed as this system is designed and produced to assure acceptable risk in its operation. Unique in its coverage, it is the only work on this subject that combines full descriptions of the management and analysis processes and procedures in one handy volume. Designed for both system safety managers and engineers, it incorporates the safety procedures used by the Department of Defense and NASA and explains basic statistical methods and network analysis methods which provide an understanding of the engineering analysis methods that follow.

We all know that safety should be an integral part of the systems that we build and operate. The public demands that they are protected from accidents, yet industry and government do not always know how to reach this common goal. This book gives engineers and managers working in companies and governments around the world a pragmatic and reasonable approach to system safety and risk assessment techniques. It explains in easy-to-understand language how to design workable safety management systems and implement tested solutions immediately. The book is intended for working engineers who know that they need to build safe systems, but aren’t sure where to start. To make it easy to get started quickly, it includes numerous real-life engineering examples. The book’s many practical tips and best practices explain not only how to prevent accidents, but also how to build safety into systems at a sensible price. The book also includes numerous case studies from real disasters that describe what went wrong and the lessons learned.

A new approach to safety, based on systems thinking, that is more effective, less costly, and easier to use than current techniques. Engineering has experienced a technological revolution, but the basic engineering techniques applied in safety and reliability engineering, created in a simpler, analog world, have changed very little over the years. In this groundbreaking book, Nancy Leveson proposes a new approach to safety—more suited to today's complex, sociotechnical, software-intensive world—based on modern systems thinking and systems theory. Revisiting and updating ideas pioneered by 1950s aerospace engineers in their System Safety concept, and testing her new model extensively on real-world examples, Leveson has created a new approach to safety that is more effective, less expensive, and easier to use than current techniques. Arguing that traditional models of causality are inadequate, Leveson presents a new, extended model of causation (Systems-Theoretic Accident Model and Processes, or STAMP), then shows how the new model can be used to create techniques for system safety engineering, including accident analysis, hazard analysis, system design, safety in operations, and management of safety-critical systems. She applies the new techniques to real-world events including the friendly-fire loss of a U.S. Blackhawk helicopter in the first Gulf War; the Vioxx recall; the U.S. Navy SUBSAFE program; and the bacterial contamination of a public water supply in a Canadian town. Leveson's approach is relevant even beyond safety engineering, offering techniques for “reengineering” any large sociotechnical system to improve safety and manage risk.

We are building systems today-and using computers to control them-that have the potential for large-scale destruction of life and environment. More than ever, software engineers and system developers, as well as their managers, must understand the issues and develop the skills needed to anticipate and prevent accidents. Nancy Leveson examines what is currently known about building safe electromechanical systems and looks at past accidents to see what practical lessons can be applied to new computer-controlled systems.

A comprehensive, up-to-date introduction to the foundations of classical safety engineering, with an emphasis on preparing for future challenges.

A practical guide to identifying hazards using common hazard analysis techniques Many different hazard analysis techniques have been developed over the past forty years. However, there is only a handful of techniques that safety analysts actually apply in their daily work. Written by a former president of the System Safety Society and winner of the Boeing Achievement and Apollo Awards for his safety analysis work, Hazard Analysis Techniques for System Safety explains, in detail, how to perform the most commonly used hazard analysis techniques employed by the system safety engineering discipline. Focusing on the twenty-two most commonly used hazard analysis methodologies in the system safety discipline, author Clifton Ericson outlines the three components that comprise a hazard and describes how to use these components to recognize a hazard during analysis. He then examines each technique in sufficient detail and with numerous illustrations and examples, to enable the reader to easily understand and perform the analysis. Techniques covered include: * Preliminary Hazard List (PHL) Analysis * Preliminary Hazard Analysis (PHA) * Subsystem Hazard Analysis (SSHA) * System Hazard Analysis (SHA) * Operating and Support Hazard Analysis (O&SHA) * Health Hazard Assessment (HHA) * Safety Requirements/Criteria Analysis (SRCA) * Fault Tree Analysis (FTA) * Event Tree Analysis (ETA) * Failure Mode and Effects Analysis (FMEA) * Fault Hazard Analysis * Functional Hazard Analysis * Sneak Circuit Analysis (SCA) * Petri Net Analysis (PNA) * Markov Analysis (MA) * Barrier Analysis (BA) * Bent Pin Analysis (BPA) * HAZOP Analysis * Cause Consequence Analysis (CCA) * Common Cause Failure Analysis (CCFA) * MORT Analysis * Software Safety Assessment (SWSA) Written to be accessible to readers with a minimal amount of technical background, Hazard Analysis Techniques for System Safety gathers, for the first time in one source, the techniques that safety analysts actually apply in daily practice. Both new and seasoned analysts will find this book an invaluable resource for designing and constructing safe systems-- in short, for saving lives.

System safety is an engineering discipline that is applied during the design and development of a product or system to identify and eliminate/mitigate hazards, thereby preventing potential mishaps and accidents. System safety is ultimately about savings lives. It is a proven technique that is currently applied on a diversity of systems, such as commercial aircraft, military aircraft, ships, trains, automobiles, nuclear power plants, weapon systems, chemical processing plants, mining, software, and medical devices. The lack of system safety costs millions of dollars in damages and loss of lives every year due to preventable mishaps.
