These emergency protocols usually start with
planning before an emergency occurs. One commonly used emergency management
protocol consists of four stages as shown in Figure
1.
Preparedness
Response
Recovery
Mitigation
Figure 1: Emergency Management Cycle (http://www.odpem.org.jm/DisastersDoHappen/DisasterManagementinJamaica/TheDisasterManagementProcess/tabid/240/Default.aspx)
Preparedness is the first step in the planning
phase of the emergency management system. In this step, the agencies
prepare themselves and make a strategy to respond to some incident or set of
emergency situations. Ideally, it should include command and control. It also
divides the tasks for agencies and removes the possible conflicts that can
occur for example four different agencies all start to provide emergency
shelter for the persons who become a victim of a disaster.
When a plan has decided which agency will provide
which services and what steps they should take to cater to the emergency. They
execute that plan and may provide some response.
After the response phase, agencies then take
steps for recovery according to the
type of incident, where they can provide medical treatment or financial
support, or help the people to overcome from that incident.
Mitigation is the fourth and last phase of the
emergency management cycle. It involves such steps that can ensure that the
same incident cannot be possible again, otherwise, in mitigation new plans are
suggested to avoid the maximum damage. Thus, it provides more precise and updated
feedback to the preparedness, to deal with future emergencies more powerfully.
A
natural disaster is an adverse
event that occurs due to change in natural by its own without any human
influence for examples floods, earthquake and tsunamis. A natural disaster can
take a lot of lives and properties damage that can vary from one person to an
entire region or cities or countries or maybe someday entire Earth might become
prey of it. Regardless of the loss of life and property damage its severity
also depends upon the ability to recover and on the available infrastructure
(G, Bankoff, et al., 2003).
