This book has 18 case study chapters investigating various injury scenarios through the use of a Human Factors and Ergonomics (HFE) analysis. Each injury scenario derives from one or more similar lawsuits (but names, places and some of the details are fictionalized). The scenarios describe a ‘slice of life’ of people interacting with products, equipment, tasks, and environments before they are seriously hurt. The forensic analysis that follows each scenario gives a background of prior similar events and systematically examines potential causes leading to the injury event. There is emphasis on the person-machine interface, human error, hazard analysis, hazard control and a model of communication-human information processing (C-HIP). Chapters are authored by highly experienced expert witnesses in HFE. The methods used are general techniques that can be applied to other injury scenarios, but would be better if employed earlier in a product’s life cycle to prevent or limit injury. The first three chapters introduce concepts useful for the analyses in the case study chapters. The last chapter offers some broad take-away points that cut across several of the case studies.

• Features contributions by persons who have extensive experience in HFE and who have served professionally in the role of an expert witness in various legal cases mostly in product liability
• Gives a broad range of situations to illustrate where HFE considerations could improve product or environmental safety. There is an emphasis on children/caregivers, and adult activities such as driving
• Uses mitigation strategies to reduce the likelihood of occurrence and severity of adverse events
• Includes a first-person scenario at the beginning of each chapter
• Allows the lessons learned to be adaptable to other domains where people interact with products and environments
