Emergency Management is a system of plans designed to handle, or manage, large-scale emergencies and disasters. These can be natural, technological or man-made. Emergency Management can be divided into four parts or phases: mitigation (prevention), preparedness, response and recovery. Actions are taken not only to prevent or reduce the frequency of disasters, but also to reduce the impacts of disasters. In the event that a disaster does occur, Emergency Management acts to coordinate response personnel and resources to address immediate damage and assists in recovery efforts to return the community back to its pre-disaster state.
