System Safety Engineering and Risk Assessment: A Practical Approach

Rating:
Summary: A good book for the student and the experienced professional
Review: I used this book to teach system safety engineering to graduate students. The author provides the reader a background into system safety that lays the ground work for a functional and proactive system safety process. This book provided workable examples to the student for comprehension of the material. Students as well as the instructor had a better understanding of system safety and the integration of the processes into general industrial and avaition safety programs/processes. I wish I had this book when I was trying to explain to my management what system safety engineering was and how it benefits the engineering department.

Summary: Illuminating Systems Safety Overview
Review: In this book, Nicholas Bahr has taken the complex discipline of systems safety and made it accessible in a logical, useful format. The book is clear and well illustrated (although a couple of the charts are a bit cumbersome and unwieldy), and calls upon numerous case studies to illustrate key points. There are separate chapters of Hazard Analysis, Fault Tree Analysis, Safety Analysis in Engineering, and Safety Management.

While useful for engineers (particularly in the chemical processing or nuclear fields), this book is written in comprehensible terms that do not require an engineering background or technical education to understand. In fact, I believe that the biggest beneficiaries of this book are not engineers at all, but non-technical managers, who desperately need to understand safety systems, but often don't. In fact the chapter on Safety Management should be required reading for any manager in a safety critical environment, as it is an excellent "how to" guide to safety management of complex systems. This chapter has examples of correct safety management, and more importantly, excellent examples of the perils of management unwillingness to prioritize safety. The case study of the Nypro UK cyclohexane plant explosion in Flixborough, England is the best detailed, and has universal applications to safety systems across varying industries. The loss of the shuttle 'Challenger' is also reviewed from a systems safety vantage point, but while there are many errors to be analyzed and learned from there, more of the lessons are industry specific than are the lessons from the Flixborough example.

I used this book in a graduate class on systems safety. This is one of the best safety books I have seen, and is the most concise text on systems safety that I have ever read, far better, for instance, than the works of Perrow. Mr. Bahr is to be commended for his work; I look forward to reading more by him in the future.
