Emergency management is the organization and management of resources and responsibilities for dealing with all humanitarian aspects of emergencies (preparedness, response, and recovery). The aim is to reduce the harmful effects of all hazards, including disasters. It should not be equated to "disaster management".
The World Health Organization defines an emergency as the state in which normal procedures are interrupted, and immediate measures need to be taken to prevent that state turning into a disaster. Thus, emergency management is crucial to avoid the disruption transforming into a disaster, which is even harder to recover from.
If possible, emergency planning should 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 become available, usually through the study of emergencies as they occur, a plan should evolve. The development of emergency plans is a cyclical process, common to many risk management disciplines, such as Business Continuity and Security Risk Management, as set out below:
There are a number of guidelines and publications regarding Emergency Planning, published by various professional organizations such as ASIS, National Fire Protection Association (NFPA), and the International Association of Emergency Managers (IAEM). There are very few Emergency Management specific standards, and emergency management as a discipline tends to fall under business resilience standards.
In order to avoid, or reduce significant losses to a business, emergency managers should work to identify and anticipate potential risks, hopefully 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 Business Continuity of critical operations post-incident. It is essential for an organization to include procedures for determining whether an emergency situation has occurred and at what point an emergency management plan should be activated. An emergency plan must be regularly maintained, in a structured and methodical manner, to ensure it is up-to-date in the event of an emergency. Emergency managers generally follow a common process to anticipate, assess, prevent, prepare, respond and recover from an incident.
Cleanup during disaster recovery involves many occupational hazards. Often these hazards are exacerbated by the conditions of the local environment as a result of the natural disaster. While individual workers should be aware of these potential hazards, employers are responsible to minimize exposure to these hazards and protect workers, when possible. This includes identification and thorough assessment of potential hazards, application of appropriate personal protective equipment (PPE), and the distribution of other relevant information in order to enable safe performance of the work. Maintaining a safe and healthy environment for these workers ensures that the effectiveness of the disaster recovery is unaffected.
