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.

Sparks, flames, and smoke resulted from the cable connection operation. 2.7.2 SAFETY DEVICES If the hazard cannot be designed out, because it is either impossible or cost-prohibitive, then the next best solution is to use fail–safe ...
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...
Murphy's law captures the idea “whatever can possibly go wrong, will.” The origin of Murphy's law is ascribed to an Air Force engineer, Captain Ed Murphy, and his colleagues, who were conducting crash tests in 1949.
After all, to err is human. Instead, this book sets forth a national agendaâ€"with state and local implicationsâ€"for reducing medical errors and improving patient safety through the design of a safer health system.
He knew that Courtenay-Latimer was always interested in seeing unusual specimens and thought she might like to come down and view the catch. Reaching the quay, Courtenay-Latimer opened the net and picked away at the layers of detritus.
In this book, she draws on more than 20 years of experience as a certification authority, an avionics manufacturer, an aircraft integrator, and a software developer to present best practices, real-world examples, and concrete ...

In addition, the book discusses causes of safety recalls; how to use metrics as differentiators to win business; criteria for a successful safety organization; and more.
This valuable guide approaches the manufacture of polymers from two perspectives, incorporating the principles of green chemistry with the guidance of the Polymer Exemption Rule to design environmentally benign polymers.
