Session 20 2
Session Objectives
1. Discuss Emergency Response from a Global Perspective
2. Describe the Life-Saving Response Functions
3. Describe the Life-Sustaining Response Functions
Session 20 3
Response
Decisions and actions aimed at limiting injuries, loss of life, and damage to property and the environment from a specific, defined
hazard
Session 20 4
Response Actions
• Relative to the disaster, response actions nay be taken:– Prior to
– During
– Immediately following
• Response begins as soon as it becomes apparent that a hazard event is imminent, and lasts until the emergency is declared to be over
Session 20 5
Response Characteristics
Response is typically performed:
• During periods of very high stress
• In a highly time-constrained environment
• With limited and imperfect information
Session 20 6
Response Phases
• Pre-Hazard
• The emergency phase: hazard effects ongoing
• The emergency phase: hazard effects have ceased
Session 20 7
Pre-Disaster Response Processes
• Warning and evacuation
• Pre-positioning of resources and supplies
• Last-minute mitigation and preparedness measures
Session 20 8
Hazard Recognition Shortfalls• The scope of the unfolding event is underestimated in light of
early impacts
• The hazard’s initial effects are unrecognizable or undetectable
• The hazard’s initial effects are kept hidden from response officials
• Disruptions of, inefficiencies in, or a lack of communications infrastructure prevents the affected from reporting an emergency in progress
• Response officials are fully engaged in response to another hazard and are unable to receive information about a new, secondary hazard
Session 20 9
Life Saving Functions
• Search and Rescue (SAR)
• First Aid Medical Treatment
• Evacuation
Session 20 10
Search and Rescue (SAR)
• SAR Actions:– Locating victims
– Extracting (rescuing) victims
– Providing initial medical first-aid treatment
• The majority of search and rescue is performed in the initial minutes and hours of a disaster by untrained, average citizens, who include victims’ friends, family members, and neighbors
Session 20 11
SAR Tasks: All Team Types
• Search collapsed buildings for victims, and rescue them
• Locate and rescue victims buried in earth, snow, and other debris
• Rescue victims from swiftly moving or high water
• Locate and rescue victims from damaged or collapsed mines
• Locate and rescue victims lost in wilderness areas
• Provide emergency medical care to trapped victims
• Provide dogs trained to locate victims by sound or smell
• Assess and control gas, electric service, and hazardous materials
• Evaluate and stabilize damaged structures
Session 20 12
First Aid Medical Treatment
• Victims may outnumber responding technicians
• Supplies may be short or depleted• Transportation of victims may be delayed,
obstructed, or simply impossible• There may be no adequate facilities
available to bring victims for longer-term care
Session 20 13
Triage
• Ranks victims according to the seriousness of their injuries, ensuring that the highest priority cases are transported to medical facilities before less serious ones
• Two systems (primarily):– START– Advanced Triage
Session 20 14
Evacuation
• Moves populations away from the hazard
• Decisions cannot be taken lightly
• Requires established statutory authority and evacuation capacity
• Most effective when limited just to the risk area
• Must be sanctioned and facilitated
Session 20 15
Life Sustaining and EM Functions
• Assessment• Treating the Hazard• Provision of Water, Food, and Shelter• Public Health• Sanitation• Safety and Security• Critical Infrastructure Resumption• Emergency Social Services• Donations Management
Session 20 16
Assessment
• Tells Responders:– What is happening– Where it is happening– What is needed– What is required to address those needs– What resources are available
Session 20 17
Assessments Continued
• Assessment Types– Situation Assessment– Needs Assessment
• Reports– Flash reports – Initial assessment report– Interim report – Specialist/technical report – Final report
Session 20 18
Treating the Hazard
• Three types of hazard effects:– Effects that are over before any response
activities may be initiated to treat them– Effects that persist, but for which no response
actions exist that can limit or eliminate them– Effects that persist that may be limited or
eliminated completely through existing response actions
Session 20 19
Water Provision• Used for:
– Hydration– Hygiene – Food preparation
• Met by:– Transporting to victims (in mass storage devices or bottles)– Tapping unexploited water sources within the community– Providing access to a functioning but restricted water source
within the community– Pumping water into the community– Providing filters or other treatments– Moving the population to another location where water is
available
Session 20 20
Food Provision• Must suit the affected population• Distribution:
– Wet– Dry
• Concerns– Nutritional Assessments– Cleanliness– Points of Distribution– Storage– Vermin– Others
Session 20 21
Shelter
• Protects from:– Natural elements– Insecurity– Damage to psychological well-being
• Immediate Shelter
• Long-Term Shelter
Session 20 22
Public Health
• Facilities that normally manage health issues may be full, overtaxed, damaged, or nonexistent
• Measures:– Crude Mortality Rate
– Morbidity Rates
– Prevalence
– Incidence
– Attack rate
Session 20 23
Public Health Response Tasks
• Rapid Assessment of Health
• Disease Prevention
• Disease Surveillance
• Outbreak Control
• Disease Management
Session 20 24
Sanitation
• Primary Sanitation Issues:– Collection and disposal of human waste. – Wastewater– Garbage (trash)– Dust– Vector control (bugs, rodents, etc.)
Session 20 25
Fatality Management• Factors that contribute to human mortality in
disasters:– Direct injuries from the hazard
– Indirect injuries resulting from the aftereffects of the hazard event
– Unrelated accidents and natural causes of death
• Actions:– Search and recovery of corpses
– Transportation of the bodies to a centralized facility
– Examination and identification of the body
– Final disposal of the body
Session 20 26
Safety and Security• Police/fire officials affected by disaster and may
be victims• Police/fire officials overtaxed• Common disaster security concerns:
– Looting – Assaults on victims – Assaults on response and recovery officials – Security within shelters and resettlement camps– Rapes– Robberies– Domestic violence
Session 20 27
Critical Infrastructure Resumption• Infrastructure = basic facilities, services, and installations
required for the functioning of a community or a society
• Critical infrastructure – vital to disaster response and the safety and security of the public
• Examples of Critical Infrastructure:– Transportation systems (land, sea, and air)
– Communications
– Electricity
– Gas and oil storage and transportation
– Water supply systems
– Emergency services
– Public health
Session 20 28
Emergency Social Services
• Psychological stresses of:– Victims– Responders
• Common names:– Disaster Counseling– Psychosocial Services– Disaster mental health
Session 20 29
Donations Management• Without an effective mechanism to accept, catalogue,
inventory, store, and distribute those donations, however, their presence can actually create what is commonly called “the second disaster.”
• Cash is best• Goods:
– Address the actual needs of the affected population
– Be appropriate for the cultural setting into which they are donated
– Be in good condition
– Be able to clear customs
