Little information about the life and work of industrial safety pioneer Herbert William Heinrich is available nowadays; most discussions and presentations of his work are based on derivatives and later interpretations of his work, or approach the matter from merely one perspective. This book sets out to rectify this and add to current discourse and knowledge by providing information based on rich first-hand sources and then facilitate a better understanding of his ideas and concepts by providing context and considering them from various sides. Based on some serious ‘safety archaeology’ which gave access to many of Heinrich’s original papers, books and detailed biographical information, this book deals with the life and work of Heinrich as well as the context he worked within, and investigates his influences and his legacy. Reappraising H. W. Heinrich defines the main themes in his work and discusses these while paying attention to their origins, the developments that came from them, interpretations and attributions, and the criticism that they may have attracted over the years. Included are Heinrich’s well-known ideas and metaphors such as the accident triangle, the accident sequence (dominoes), the hidden cost of accidents, the role of the worker and management responsibility. The final chapter features a discussion of Heinrich’s relevance today. This book will provide safety scholars, researchers, specialists and students with a unique resource dedicated to the work of this hugely influential safety innovator, and offering many previously unavailable insights.
