This is a composite of their message: The book is great, but some of your chapters need updating. This third edition continues to address those subjects that the author believesmustbemasteredbythosewhostrivetoattainprofessional status in the practice of safety. In the essay form used, most of these subjects are not addressed elsewhere. Their purpose is to provide • A basis for introspection by those safety professionals who seek to improve their performance, to be perceived by management as pro- viding value, and to achieve professional recognition • A solid foundation with respect to the practice of safety for students in safety degree programs ThesecondeditionofOnthePracticeofSafety waswrittenin1995and 1996.Eachchapterhasbeenupdatedinthisthirdeditionandhasalsobeen extended or revised as needed. In several chapters, this work is extensive. Also, research I conducted on pertinent safety management subjects since 1996 provided new chapters, of which there are five. They are • Chapter 7, “Heinrich Revisited: Truisms or Myths” • Chapter 8, “Addressing Severe Injury Potential” • Chapter 15, “Acceptable Risk” • Chapter 21, “A Safety Management Standard: A Futuristic View” (This is a replacement for a chapter in the second edition which per- tained to an expected safety and health standard to be issued by the ix x PREFACETOTHETHIRDEDITION Occupational Safety and Health Administration [OSHA], the possi- bility of which is remote, at least temporarily.) • Chapter 23, “Behavior-Based Safety” This book is unique in its style, purpose, and content. This is what one college professor said about it. “Your book has made me think differently about safety management, and what I want my students to learn. I hope you keep the present format in which each chapter is a stand-alone essay. I know that requires some repetition but the reader benefits by not having to refer to other chapters while reading the chapter at hand.” With partial success, that format has been retained. Recognition has been given in several chapters to a transition that continues to move forward, and that is the bringing together under one management the staff responsibilities for safety, occupational health, and environmental affairs. Often in the book, safety is the only term used, but it connotes all of the foregoing responsibilities. As has been the case in previous editions, this third edition emphasizes the need to balance the design and engineering aspects, the management and operations aspects, and the task performance aspects of the practice of safety. FRED A. MANUELE PREFACE TO THE SECOND EDITION Four plus years have passed since the first edition of this book was published. And transitions in the practice of safety have continued to take place, requiring some revisions in all of the essays originally writ- ten and the addition of new ones. These are the new or significantly revised chapters. “Transitions in the Practice of Safety” is the first chapter in this edi- tion, and it replaces the first chapter in the previous edition. It addressed the changes that have taken place in the business climate and their effect on career planning. It also discusses how those changes require having a practice that has a sound theoretical and practical base, and the opportu- nities they present. This new chapter also includes the substance of the last chapter in the first edition, which was “On Management Fads.” The chapter on the “Principles for the Practice of Safety: A Basis for Discussion”shouldbeofinteresttothosewhothinkaboutthesubstanceof whatsafetyprofessionalsdoandwanttomovethestateoftheart forward. In recognition of the need to further our knowledge of hazards-related incident causation, a chapter offers “A Systemic Causation Model for Hazards Related Occupational Incidents.” “Designer Incident Investigation” is to help safety personnel craft prac- tical and realistic incident investigation systems, after considering the resources available and organizational sophistication. The chapter “Guidelines: Designing for Safety” is a concept paper that is to assist those whose responsibilities are extended into the design pro- cesses. In the first edition, there were separate chapters offering comments on hazards and risks. They have been combined into one chapter titled “Comments on Hazards and Risks.” The original chapter “Anticipating OSHA’s Standard for Safety and Health Program Management” has been extended to include comments xi xii PREFACETOTHESECONDEDITION on the safety management audit system that OSHA is exploring. Having sound safety performance measurement systems has become more important: thus the new chapter “Measurement of Safety Perfor- mance.” This second edition emphasizes the need to keep in balance the design andengineeringaspectsandthemanagementandtaskperformanceaspects of the practice of safety.
