Disaster Management
Disaster management is the creation of
plans through which communities reduce vulnerability to hazards and cope with
disasters. Events covered
by disaster management include acts of terrorism, industrial sabotage, fire, natural disasters (such as earthquakes, hurricanes, etc.), public disorder, industrial accidents, and communication failures.
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:
·
Recognition
or identification of risks
·
Ranking or
evaluation of risks
·
Responding
to significant risks
·
Tolerate
·
Treat
·
Transfer
·
Terminate
·
Resourcing
controls
·
Reaction
Planning
·
Reporting
& monitoring risk performance
·
Reviewing
the Risk Management framework
Disaster
management consists of five phases: prevention, mitigation, preparedness,
response and recovery.
1. Prevention actions taken to
avoid and incident. Stopping an incident from occurring. Deterrence
operations and surveillance.
2. Preparedness activities increase
a community's ability to respond when a disaster occurs. Typical
preparedness measures include developing mutual aid agreements and memorandums
of understanding, training for both response personnel and concerned citizens,
conducting disaster exercises to reinforce training and test capabilities, and
presenting all-hazards education campaigns.
3. Response actions carried out
immediately before, during, and immediately after a hazard impact, which are
aimed at saving lives, reducing economic losses, and alleviating suffering. Response
actions may include activating the emergency operations center, evacuating
threatened populations, opening shelters and providing mass care, emergency
rescue and medical care, fire fighting, and urban search and rescue.
4. Recovery actions
taken to return a community to normal or near-normal conditions, including the
restoration of basic services and the repair of physical, social and economic
damages. Typical recovery actions include debris cleanup, financial
assistance to individuals and governments, rebuilding of roads and bridges and
key facilities, and sustained mass care for displaced human and animal
populations.
5. Mitigation refers to measures
that prevent an emergency, reduce the chance of an emergency happening, or
reduce the damaging effects of unavoidable emergencies.
Typical mitigation measures include establishing building codes and zoning
requirements, installing shutters, and constructing barriers such as levees.
