Management of Hazardous Energy: Deactivation, De-Energization, Isolation, and Lockout

Extracting lessons learned from hundreds of accident summaries, this book explains the effects of hazardous energy on humans, and discusses the critical role of human factors, including limitations of information processing and sensory overload, on the safe performance of work. It then covers how equipment, machines, and systems operate and are controlled and develops the logic for assessing and managing hazardous energy during production, and in standby and shutdown mode. Simple, logical, practical procedures for deactivation, de-energization, isolation, and lockout are essential for ensuring worker safety and achieving regulatory compliance. The book applies these concepts to different systems in which hazardous energy is present.
