This book examines the safety and security of event planning, from small and mid-sized events to large scale events requiring cross-jurisdictional and, potentially, national authority involvement. Natural (earthquakes, tsunamis, severe weather) and man-made (terrorism, chemical spills, train derailments) disasters present challenges for large event planners. Risk assessments are covered as well as the event planning process, response planning, crisis management, and the decision-making and chain-of-authority framework necessary to take critical action during and immediately following a crisis.
