System safety is the application of engineering and management principles, criteria, and techniques to optimize safety within the constraints of operational effectiveness, time, and cost throughout all phases of the system life cycle. System safety is to safety as systems engineering is to engineering. When performing appropriate analysis, the evaluation is performed holistically by tying into systems engineering practices and ensuring that system safety has an integrated system-level perspective.The NASA System Safety Handbook presents the overall framework for System Safety and provides the general concepts needed to implement the framework. The treatment addresses activities throughout the system life cycle to assure that the system meets safety performance requirements and is as safe as reasonably practicable.This handbook is intended for project management and engineering teams and for those with review and oversight responsibilities. It can be used both in a forward-thinking mode to promote the development of safe systems, and in a retrospective mode to determine whether desired safety objectives have been achieved.The topics covered in this volume include general approaches for formulating a hierarchy of safety objectives, generating a corresponding hierarchical set of safety claims, characterizing the system safety activities needed to provide supporting evidence, and presenting a risk-informed safety case that validates the claims. Volume 2, to be completed in 2012, will provide specific guidance on the conduct of the major system safety activities and the development of the evidence.

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.
Demonstrating safety for the application of ever more complex technologies is a formidable task. System engineers often do not have the appropriate training, are unfamiliar with the range of safety approaches, tools and techniques, and their managers do not know when and how these may be applied and appropriately resourced. Aircraft system safety provides a basic skill set for designers, safety practitioners, and their managers by exploring the relationship between safety, legal liability and regulatory requirements. Different approaches to measuring safety are discussed, along with the appropriate safety criteria used in judging acceptability.A wealth of ideas, examples, concepts, tools and approaches from diverse sources and industries is used in Aircraft system safety to bring the theory of safety concisely together in a practical and comprehensive reference. Engineering students, designers, safety assessors (and their managers), regulatory authorities (especially military), customers and projects teams should find Aircraft system safety provides an invaluable guide in appreciating the context, value and limitations of the various safety approaches used in cost-effectively accomplishing safety objectives. - Explores the practical aspects of safety - Invaluable guide for students, designers, and safety assessors - Written by a leading expert in the field
