 Slips, trips, missteps and falls can have consequences that range from losses of balance to severe injuries with costly, disabling, life-altering, or fatal outcomes. This third edition is a comprehensive reference for all aspects of ambulation slips, trips, missteps, and falls. The authors have provided the material as a valuable reference to understand how ambulating people slip, trip, misstep, and fall and a guide for implementing preventive or mitigating controls to reduce the likelihood of these incidents occurring. This third edition includes updated scientific literature, standards, codes, and guidelines; entirely new chapters on distracted ambulation and drug-induced falls; and ordering of chapters for more helpful information flow. The previous versions are Falls and Related Injuries: Slips, Trips, Missteps and Their Consequences published in 2002 and Slips, Trips, Missteps, and Their Consequences (Second Edition) published in 2007. The first chapter provides an overview of the role of the human ambulation process and covers human factors and ergonomics principles. Chapters 2 through 8 address why people slip, trip, misstep, and fall; the different types of falls; the fall-inducing hazards; and other human components of the ambulation system. Chapters 9 through 11 discuss the effects of distractions, aging, and pharmacology on ambulation and falls. Chapters 12 through 22 apply human factors/ergonomics, biomechanical, and cognitive principles to ambulation environments. Also discussed are the standards of care to eliminate hazards or control exposure and mitigate the severity of predictable or expected hazard exposure consequences. Chapter 23 addresses the role and value of an expert witness in the preparing an ambulation fall-related case. Chapter 24 is a fall prevention manual that contains checklists for inspecting and identifying premise ambulation hazards. Chapter 25 includes a list of codes and standards applicable to ambulation falls at publication time. Gary M. Bakken, Cindy A. LaRue, and H. Harvey Cohen collaborated to author Chapters 1-10 and 12-25. Chapter 11was co-authored by James J. O’Donnell III and James T. O’Donnell.
