Emergency management plans allow communities to reduce vulnerability to hazards and cope with disasters. These plans do not avert or eliminate threats, instead focuses on decreasing impact of disasters. Failure to create a plan could lead to death and injuries, damage to property, and lost revenue. Events covered by disaster emergency plans include acts of terrorism, industrial sabotage and accidents, fire, natural disasters, and communication failures, to name a few.
There are a number of guidelines and publications regarding Emergency Planning. All of them include the aim to prevent emergencies from occurring, and failing that, should develop a good action plan to mitigate the results and effects of any emergencies. As time goes on, and more data becomes available, usually through the study of emergencies as they occur, a plan should evolve.
In order to avoid, or reduce significant losses emergency management should identify and anticipate potential risks, to reduce their probability of occurring. In the event that an emergency does occur, managers should have a plan prepared to mitigate the effects of that emergency, as well as to ensure continuity of critical operations post-incident.
