[u]Emergency management or Disaster Management [/u]
Overview
Emergencies, Disasters, and Catastrophes are not gradients, they are separate, distinct problems that require distinct strategies of response[citation needed]. Disasters are events distinguished from everyday emergencies by four factors: Organizations are forced into more and different kinds of interactions than normal; Organizations lose some of their normal autonomy; Performance standards change, and; More coordinated public sector/private sector relationships are required.[2]
Catastrophes are distinct from disasters in that: Most or all of the community built structure is heavily impacted; Local officials are unable to undertake their usual work roles; Most, if not all, of the everyday community functions are sharply and simultaneously interrupted, and; Help from nearby communities cannot be provided.[3]
Assets are categorized as either living things, non-living things, cultural or economic. Hazards are categorized by their cause, either natural or human-made. The entire strategic management process is divided into four fields to aid in identification of the processes. The four fields normally deal with risk reduction, preparing resources to respond to the hazard, responding to the actual damage caused by the hazard and limiting further damage (e.g., emergency evacuation, quarantine, mass decontamination, etc.), and returning as close as possible to the state before the hazard incident. The field occurs in both the public and private sector, sharing the same processes, but with different focuses.
Mitigation
Mitigation efforts are attempts to prevent hazards from developing into disasters altogether or to reduce the effects of disasters. Mitigation is the effort to reduce loss of life and property by lessening the impact of disasters. This is achieved through risk analysis, which results in information that provides a foundation for mitigation activities that reduce risk, and flood insurance that protects financial investment,.[8] The mitigation phase differs from the other phases in that it focuses on long-term measures for reducing or eliminating risk.[1] The implementation of mitigation strategies is a part of the recovery process if applied after a disaster occurs.[1]
Mitigation measures can be structural or non-structural. Structural measures use technological solutions like flood levees and building retrofitting for earthquakes. Non-structural measures include legislation, land-use planning (e.g. the designation of non-essential land like parks to be used as flood zones), and insurance.[9]
Mitigation is the most cost-efficient method for reducing the effect of hazards although not always the most suitable. Mitigation includes providing regulations regarding evacuation, sanctions against those who refuse to obey the regulations (such as mandatory evacuations), and communication of risks to the public.[10] Some structural mitigation measures may harm the ecosystem.
Response
The response phase includes the mobilization of the necessary emergency services and first responders in the disaster area. This is likely to include a first wave of core emergency services, such as firefighters, police and ambulance crews. When conducted as a military operation, it is termedDisaster Relief Operation (DRO) and can be a follow-up to a Non-combatant evacuation operation(NEO). They may be supported by a number of secondary emergency services, such as specialist rescue teams.
A well rehearsed emergency plan developed as part of the preparedness phase enables efficient coordination of rescue. Where required, search and rescue efforts commence at an early stage. Depending on injuries sustained by the victim, outside temperature, and victim access to air and water, the vast majority of those affected by a disaster will die within 72 hours after impact.[14]
