This book aims to provide a multidisciplinary approach to risk management. Risk management is addressed in ergonomics, soils, business, public management, mines, mechanics, information technology, and learning systems. These chapters present different evaluation methods and different approaches. The book is a valuable support for researchers, practitioners, students, professionals, entrepreneurs and employees. The risk approach must be aligned with organizational policy and development strategies. Treatment techniques are complex and require experience and evaluation of organizational history. The new approaches and the environment dynamics have contributed to the emergence of new risks for which the approach must differ.
