Emergency
management (or disaster management) is the discipline of dealing with and
avoiding risks. It is a discipline that involves preparing for disaster
before it occurs, disaster response (e.g. emergency evacuation, quarantine,
mass decontamination, etc.), as well as supporting, and rebuilding society
after natural or human-made disasters have occurred. In general, any Emergency
management is the continuous process by which all individuals, groups, and
communities manage hazards in an effort to avoid or ameliorate the impact of
disasters resulting from the hazards. Continue...
Actions taken depend in part on
perceptions of risk of those exposed. Effective emergency management relies
on thorough integration of emergency plans at all levels of government and
non-government involvement. Activities at each level (individual, group,
community) affect the other levels. It is common to place the responsibility
for governmental emergency management with the institutions for civil defense
or within the conventional structure of the emergency services. In the private
sector, emergency management is sometimes referred to as business continuity
planning.
Emergency
Management is one of a number of terms which, since the end of the Cold War,
have largely replaced Civil defense, whose original focus was protecting
civilians from military attack. Modern thinking focuses on a more general
intent to protect the civilian population in times of peace as well as in times
of war. Another current term, Civil Protection is widely used within the
European Union and refers to government-approved systems and resources whose
task is to protect the civilian population, primarily in the event of natural
and human-made disasters. Within EU countries the term Crisis Management
emphasises the political and security dimension rather than measures to satisfy
the immediate needs of the civilian population.[citation needed] An academic
trend is towards using the term disaster risk reduction, particularly for
emergency management in a development management context. This focuses on the
mitigation and preparedness aspects of the emergency cycle (see below).
Phases and professional
activities
The
nature of management depends on local economic and social conditions. Some
disaster relief experts such as Fred Cuny have noted that in a sense the only
real disasters are economic.[3] Experts, such as Cuny, have long noted that the
cycle of emergency management must include long-term work on infrastructure,
public awareness, and even human justice issues. This is not important in
developing nations. The process of emergency management involves four phases:
mitigation, preparedness, response, and recovery.

Mitigation
Mitigation
efforts attempt to prevent hazards from developing into disasters altogether,
or to reduce the effects of disasters when they occur. The mitigation phase
differs from the other phases because it focuses on long-term measures for
reducing or eliminating risk.[1] The implementation of mitigation strategies
can be considered a part of the recovery process if applied after a disaster
occurs.[1] Mitigative measures can be structural or non-structural. Structural
measures use technological solutions, like flood levees. Non-structural
measures include legislation, land-use planning (e.g. the designation of
nonessential land like parks to be used as flood zones), and insurance.
Mitigation is the most cost-efficient method for reducing the impact of
hazards, however it is not always suitable. Mitigation does include providing
regulations regarding evacuation, sanctions against those who refuse to obey
the regulations (such as mandatory evacuations), and communication of potential
risks to the public.[4] Some structural mitigation measures may have adverse
effects on the ecosystem.
A
precursor activity to the mitigation is the identification of risks. Physical
risk assessment refers to the process of identifying and evaluating hazards.[1]
The hazard-specific risk (Rh) combines both the probability and the level of
impact of a specific hazard. The equation below gives that the hazard times the
populations’ vulnerability to that hazard produce a risk. Catastrophe modeling
The higher the risk, the more urgent that the hazard specific vulnerabilities
are targeted by mitigation and preparedness efforts. However, if there is no
vulnerability there will be no risk, e.g. an earthquake occurring in a desert
where nobody lives.
Preparedness
In
the preparedness phase, emergency managers develop plans of action for when the
disaster strikes. Common preparedness measures include:
communication
plans with easily understandable terminology and methods.
proper
maintenance and training of emergency services, including mass human resources
such as community emergency response teams.
development
and exercise of emergency population warning methods combined with emergency
shelters and evacuation plans.
stockpiling,
inventory, and maintain disaster supplies and equipment[5]
develop
organizations of trained volunteers among civilian populations. (Professional
emergency workers are rapidly overwhelmed in mass emergencies so trained,
organized, responsible volunteers are extremely valuable. Organizations like
Community Emergency Response Teams and the Red Cross are ready sources of
trained volunteers. Its emergency management system has gotten high ratings
from both California, and FEMA.)
Another
aspect of preparedness is casualty prediction, the study of how many deaths or
injuries to expect for a given kind of event. This gives planners an idea of
what resources need to be in place to respond to a particular kind of event.
Emergency
Managers in the planning phase should be flexible, and all encompassing -
carefully recognizing the risks and exposures of their respective regions and
employing unconventional, and atypical means of support. Depending on the
region - municipal, or private sector emergency services can rapidly be
depleted and heavily taxed. Non-governmental oganizations that offer desired
resources i.e. transportation of displaced homeowners to be conducted by local
school district buses, evacuation of flood victims to be performed by mutual
aide agreements between fire departments and rescue squads, should be
identified early in planning stages, and practiced with regularity.
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 termed Disaster 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.[6]
Organizational
response to any significant disaster - natural or terrorist-borne - is based on
existing emergency management organizational systems and processes: the Federal
Response Plan (FRP) and the Incident Command System (ICS). These systems are
solidified through the principles of Unified Command (UC) and Mutual Aid (MA)
Recovery
The
aim of the recovery phase is to restore the affected area to its previous
state. It differs from the response phase in its focus; recovery efforts are
concerned with issues and decisions that must be made after immediate needs are
addressed.[1] Recovery efforts are primarily concerned with actions that
involve rebuilding destroyed property, re-employment, and the repair of other
essential infrastructure.[1] An important aspect of effective recovery efforts
is taking advantage of a ‘window of opportunity’[7] for the implementation of
mitigative measures that might otherwise be unpopular. Citizens of the affected
area are more likely to accept more mitigative changes when a recent disaster
is in fresh memory.
In
the United States, the National Response Plan dictates how the resources
provided by the Homeland Security Act of 2002 will be used in recovery
efforts.[1] It is the Federal government that often provides the most technical
and financial assistance for recovery efforts in the United States.[1]
Phases and personal
activities
Mitigation
Personal
mitigation is mainly about knowing and avoiding unnecessary risks. This
includes an assessment of possible risks to personal/family health and to
personal property.
One
example of mitigation would be to avoid buying property that is exposed to
hazards, e.g. in a flood plain, in areas of subsidence or landslides.
Homeowners may not be aware of a property being exposed to a hazard until it
strikes. However, specialists can be hired to conduct risk identification and
assessment surveys. Purchase of insurance covering the most prominent
identified risks is a common measure.
Personal
structural mitigation in earthquake prone areas includes installation of an
Earthquake Valve to instantly shut off the natural gas supply to a property,
seismic retrofits of property and the securing of items inside a building to
enhance household seismic safety. The latter may include the mounting of
furniture, refrigerators, water heaters and breakables to the walls, and the
addition of cabinet latches. In flood prone areas houses can be built on poles,
as in much of southern Asia. In areas prone to prolonged electricity black-outs
installation of a generator would be an example of an optimal structural
mitigation measure. The construction of storm cellars and fallout shelters are
further examples of personal mitigative actions.
Mitigation involves
Structural and Non-structural measures taken to limit the impact of disasters.
Structural Mitigation:-
This involves proper
layout of building, particularly to make it resistant to disasters.
Non Structural
Mitigation:-
This involves measures
taken other than improving the structure of building.

Preparedness
is aimed at preventing a disaster from occurring, personal preparedness focuses
on preparing equipment and procedures for use when a disaster occurs, i.e.
planning. Preparedness measures can take many forms including the construction
of shelters, installation of warning devices, creation of back-up life-line
services (e.g. power, water, sewage), and rehearsing evacuation plans. Two
simple measures can help prepare the individual for sitting out the event or
evacuating, as necessary. For evacuation, a disaster supplies kit may be
prepared and for sheltering purposes a stockpile of supplies may be created.
The preparation of a survival kit such as a "72-hour kit", is often
advocated by authorities. These kits may include food, medicine, flashlights,
candles and money.
Response
The
response phase of an emergency may commence with search and rescue but in all
cases the focus will quickly turn to fulfilling the basic humanitarian needs of
the affected population. This assistance may be provided by national or
international agencies and organisations. Effective coordination of disaster
assistance is often crucial, particularly when many organisations respond and
local emergency management agency (LEMA) capacity has been exceeded by the
demand or diminished by the disaster itself.
On
a personal level the response can take the shape either of a shelter in place
or an evacuation. In a shelter-in-place scenario, a family would be prepared to
fend for themselves in their home for many days without any form of outside
support. In an evacuation, a family leaves the area by automobile or other mode
of transportation, taking with them the maximum amount of supplies they can
carry, possibly including a tent for shelter. If mechanical transportation is
not available, evacuation on foot would ideally include carrying at least three
days of supplies and rain-tight bedding, a tarpaulin and a bedroll of blankets
being the minimum.
Recovery
The
recovery phase starts after the immediate threat to human life has subsided.
During reconstruction it is recommended to consider the location or
construction material of the property.
The
most extreme home confinement scenarios include war, famine and severe
epidemics and may last a year or more. Then recovery will take place inside the
home. Planners for these events usually buy bulk foods and appropriate storage
and preparation equipment, and eat the food as part of normal life. A simple
balanced diet can be constructed from vitamin pills, whole-meal wheat, beans,
dried milk, corn, and cooking oil.[8] One should add vegetables, fruits, spices
and meats, both prepared and fresh-gardened, when possible.
As a profession
Emergency
managers are trained in a wide variety of disciplines that support them through
out the emergency life-cycle. Professional emergency managers can focus on
government and community preparedness (Continuity of Operations/Continuity of
Government Planning), or private business preparedness (Business Continuity
Management Planning). Training is provided by local, state, federal and private
organizations and ranges from public information and media relations to
high-level incident command and tactical skills such as studying a terrorist
bombing site or controlling an emergency scene.
In
the past, the field of emergency management has been populated mostly by people
with a military or first responder background. Currently, the population in the
field has become more diverse, with many experts coming from a variety of
backgrounds without military or first responder history. Educational
opportunities are increasing for those seeking undergraduate and graduate
degrees in emergency management or a related field. There are eight schools in
the US with emergency management-related doctorate programs, but only one
doctoral program specifically in emergency management.[9]
Professional
certifications such as Certified Emergency Manager (CEM) and Certified Business
Continuity Professional (CBCP) are becoming more common as the need for high
professional standards is recognized by the emergency management community,
especially in the United States.
Tools
In
recent years the continuity feature of emergency management has resulted in a
new concept, Emergency Management Information Systems (EMIS). For continuity
and interoperability between emergency management stakeholders, EMIS supports
the emergency management process by providing an infrastructure that integrates
emergency plans at all levels of government and non-government involvement and
by utilizing the management of all related resources (including human and other
resources) for all four phases of emergencies. In the healthcare field,
hospitals utilize HICS (Hospital Incident Command System) which provides
structure and organization in a clearly defined chain of command with set
responsibilities for each division.
Within other
professions
Practitioners
emergency management (disaster preparedness) come from an increasing variety of
backgrounds as the field matures. Professionals from memory institutions (e.g.,
museums, historical societies, libraries, and archives) are dedicated to
preserving cultural heritage—objects and records contained in their
collections. This has been an increasingly major component within these field
as a result of the heightened awareness following the events on 9/11, the
hurricanes in 2005, and the collapse of the Cologne Archives.
To
increase the opportunity for a successful recovery of valuable records, a
well-established and thoroughly tested plan must be developed. This plan must
not be overly complex, but rather emphasize simplicity in order to aid in
response and recovery. As an example of the simplicity, employees should
perform similar tasks in the response and recovery phase that they perform
under normal conditions. It should also include mitigation strategies such as
the installation of sprinklers within the institution. This task requires the
cooperation of a well-organized committee led by an experienced
chairperson.[10] Professional associations schedule regular workshops and hold
focus sessions at annual conferences to keep individuals up to date with tools
and resources in practice in order to minimize risk and maximize recovery.
Tools
The
joint efforts of professional associations and cultural heritage institutions
have resulted in the development of a variety of different tools to assist
professionals in preparing disaster and recovery plans. In many cases, these
tools are made available to external users. Also frequently available on
websites are plan templates created by existing organizations, which may be
helpful to any committee or group preparing a disaster plan or updating an
existing plan. While each organization will need to formulate plans and tools
which meet their own specific needs, there are some examples of such tools that
might represent useful starting points in the planning process. These have been
included in the External Links section.
