DISASTER MANAGEMENT



INTRODUCTION
}  Disaster management includes:
      Types of disasters
      How to prepare for disasters?
      How to respond?
      If we are adequately prepared it is possible to reduce an impact of a disaster.
}  Impact can be reduced by understanding of preventive actions, having knowledge of certain lifesaving tools & techniques.

What is a disaster???
}  “A sudden accident or natural event that causes great damage or loss of life" - Oxford Dictionary.
}  A serious disruption of the functioning of a society, causing widespread human, material, or environmental losses which exceed the ability of the affected society to cope using its own resources.”



HAZARD
}  A natural or human made event that threatens to adversely affect human life, property or activity to the extent of causing a disaster.
}  Disaster Risk = Hazard +Vulnerability

RISK
}  Risk is a measure of the expected losses due to a hazardous event of a particular magnitude occurring in a given area over a specific time period.
}  Nature of the Hazard
}  Vulnerability of the elements which are affected.
}   Economic value of those elements.

VULNERABILITY
}  It is defined as “the extent to which a community, structure, service, and/or geographic area is likely to be damaged or disrupted by the impact of particular hazard, depending on their nature, construction and proximity to a disaster prone area”

EFFECTS
}  Physical: Infrastructure damage
}  Economic: Power disruption, Water problems, Agricultural damage
}  Social: Telecommunication loss, poverty
}  Emotional: mortality
}  Health:  injuries, morbidity, epidemic  
}  Environmental: Damage to inland and coastal environments, Flooding,  Landslides
}  Cultural: Disruption of standard of living, lifestyle
}  The loss during the actual event is not necessarily be high, but, the losses become very high due to inability to manage the situation in a timely manner and inability to properly manage and secure the utilities, like: electricity, gas, water etc.

WHY SHOULD WE STUDY??
}  Asia-pacific region: 60% of major natural disasters.
}  India manifests many natural disasters like floods, cyclones, landslides, earthquakes etc. due to vast variation of geographical terrain and climatic conditions.
}  INDIA: 2.4% of world’s land area. 7th largest country of the world with 15% of the world’s population.



ARE WE PREPARED???

DISASTER MANAGEMENT
DEFINITION:
}  Is a systematic process that aims to reduce the negative impact or consequences of adverse events.  

DISASTER MANAGEMENT CYCLE



MITIGATION
}  Mitigation refers to all the actions taken before a disaster to reduce its impacts on nation or community.
}  mitigation= prevention + preparedness
Four sets of tools that could be used to prevent or mitigate disasters include:
a)      Hazard management and vulnerability reduction
b)      Economic diversification
c)      Political intervention and commitment
d)     Public awareness

PREPAREDNESS
}  Measures which enable government, organizations, communities and individuals to respond rapidly and effectively to disaster situation.
Includes:
      Emergency exercises/training
      Warning systems
      Emergency communications systems
      Evacuations plans and training
      Emergency personnel/contact lists
      Mutual aid agreements
      Public information/education

Disaster drills/ Mock tests
}  Well planned, organized and coordinated.
}  Can be scheduled periodic or unannounced.

RESPONSE
}  Disaster response is the sum total of actions taken by people and institutions in the face of disaster.
}  The focus in the response phase is on meeting the basic needs of the people until more permanent and sustainable solutions can be found.
}  One of the main goals of disaster management is the promotion of sustainable livelihoods and their protection.
}  Where this goal is achieved, people have a greater capacity to deal with disasters and their recovery is more rapid and long lasting.

Aims of disaster response
  1. To ensure the survival of the maximum possible number of victims, keeping them in the best possible health in the circumstances.
  2. To re-establish self-sufficiency and essential services as quickly as possible for all population groups.
  3. To repair or replace damaged infrastructure and regenerate viable economic activities.
  4. In situations of civil or international conflict, the aim is to protect and assist the civilian population, in close collaboration with the International Committee of the Red Cross (ICRC) and in compliance with international conventions.

Disaster Response Activities
  1. Warning: Evacuate or secure property
  2. Evacuation and migration 
  3. Search and rescue 
  4. Post-disaster assessment: relief needs
  5. Relief: material aid and emergency medical care
  6. Logistics and supply
  7. Communication and information management
  8. Survivor response and coping: new and special needs
  9. Security: rights and safety
  10. Emergency operations management: Policies and procedures
  11. Rehabilitation: resume functioning, assist victim’s self-help efforts.
  12. Reconstruction: Permanent construction, services
  13. Revitalization of the economy.

Recovery
}  Returning the community to normal.
}  As the emergency is brought under control growing number of activities aimed at restoring their lives and the infrastructure that supports them.
Short-term recovery
}  Restore interrupted utility services, clear roads, temporary housing, public information, health and safety education, provide food and shelter for those displaced by the disaster. (few weeks)
Long-term recovery
}  Complete re-development of damaged areas for the community to return to a state that is equal to or even better than it was before. (months- years)

Steps of recovery
  1. Gathering basic information
  2. Organizing recovery
  3. Mobilizing resources for recovery
  4. Administering recovery
  5. Regulating recovery
  6. Coordinating recovery activities
  7. Evaluating recovery
Lifesaving tools AND techniques

VICTIM EVACUATION METHODS
}  Required to evacuate injured person from an emergency scene to a location of safety.
}  Manual carries are tiring for the rescuer and involve the risk of increasing the severity of the casualty's injury.
}  Choose the evacuation techniques that will be least harmful, both to rescuer and the victim.

Victim Drag and Carry Techniques
Tied-Hands Crawl


}  Crawl underneath a low structure.
}  Victim heavier than you, unconscious.
}  Head is not supported.
}  Longer distances to lift a victim safely.

One Person Arm Carry

One Person Pack-Strap Carry


Fire Man Carry

}  Longer distances.

Two Person Carry ( by arms & legs)

Chair Carry


}  Carrying victims up and down stairs or through narrow or uneven areas.

Ankle Pull
}  Fastest method for moving a victim a short distance over a smooth surface.


Shoulder Pull
}  Preferred over the ankle pull.
}  Requires the rescuer to bend over at the waist while pulling.


Blanket Drag
Preferred method for dragging a victim from confined area.
Keep your back as straight as possible.
Use your legs, not your back.


Two Handed Seat


Four Handed Seat


Three Person Carry
}  This technique is for lifting a patient into a bed or stretcher, or for transporting to short distances.


Improvised Stretcher


Blanket Stretcher


TRIAGE

}  It is the process of determining the priority of patient’s treatments based on the severity of their condition.
}  Useful for rapid evaluation, allotment of priority for treatment and/or evacuation of patients.
}  Also used in emergency departments.

Principles:
  1. Every pt. should be received and triaged by appropriate, skilled health care professionals.
  1. Triage process shouldn’t cause a delay in the delivery of effective clinical care.
  1. Triage is a clinical managerial decision and must involve collaborative planning.

Objectives
  1. Ensure immediate medical intervention in life threatening situations.
  2. Expedite the care of patients through a systemic initial assessment.
  3. Ensure that patients are prioritized for treatment in accordance with the severity of their condition.
  4. Decrease the morbidity associated with medical conditions through early intervention.
  5. Assist pts. requiring treatment in another department and health care institutions.
  6. Improve public relations by communicating appropriate information to people accompanying the pt.
  7. Improve pt. flow
  8. Assist in performance measurement.
