Disaster Planning And Management Flashcards
(367 cards)
Disasters
Events that occur when significant numbers of people are exposed to hazards to which they are vulnerable, with resulting injury and loss of life, often combined with damage to property and livelihoods
Paradigm change required in disaster management
Change from the application of unlimited resources for the greatest good of each individual client, to the allocation of limited resources for the greatest good to the greatest number of casualties
Main causes of disaster events
- Nature
- Technology
- Human conflict
- Combination
Examples of natural disaster potential hazards
- Firestorms
- Flood
- Landshift
- Tornado
- Epidemic
- Earthquake
- Volcano
- Hurricane
- High winds
- Blizzard
- Heat wave
Examples of technological disaster potential hazards
- Hazmat spills
- Explosions
- Utility failure
- Building collapse
- Transportation accident
- Power outage
- Nuclear accident
- Dam failure
- Fire
- Water loss
- Ruptured gas main
Examples of conflict disaster potential hazards
- Riots
- Strikes
- Suicide bombings
- Bomb threat
- Employee violence
- Mass shootings
- Equipment sabotage
- Hostage events
- Transportation disruption
- Weapons of mass destruction
- Computer viruses/worms
Parameters to classify disasters
- Number of fatalities
- Number of ill/injured
- Length of time for the impact
- Rescue time
- Radius of disaster area
Richter scale
Used to measure magnitude of earthquake
Modified Mercalli Intersity (MMI)
Subjective measurement used to describe the intensity, or nature and spatial extent of damage from an earthquake
Safffir-Simpson scale
Used to measure the strength of hurricanes
Fujiita scale
Used to measure the strength of tornados
Nat-tech disasters
Technological emergencies that result from natural disasters
Aka joint disasters
Examples of nat-tech disasters
- Earthquake causing ruptured natural gas lines and fires
2. Tornado causing chemical tank breach and chemical spill
Characteristics of nat-tech disasters
- Response for both events required simultaneously
- Likely to be more than one technologic event
- Major utilities may be disrupted
- Mitigation efforts may not work as anticipated because of natural disaster
Factors that contribute to the increased probability and severity of consequences of disasters
- Risk of disasters is greater
- People have become more vulnerable to nature
- Technologic disasters are more frequent and severe as result of increased complexity and dependency in these area
Reasons why risk of disaster is greater currently
- Growing population
- More technology
- Increased political turbulence resulting in threat of terrorism
Reasons people are currently more vulnerable to nature
- Mass migration
- Urbanization
- Building in high risk areas
- War
Dependency on the following areas causes technologic disasters to be more severe and frequent
- Telecommunications
- Computer systems
- High rise buildings
- Widespread power supply grids
- Global marketing
Disaster nursing
The systematic and flexible utilization of knowledge and skills specific to disaster related nursing, and the promotion of a wide range of activities to minimize the health hazards and life threatening damage caused by disasters in collaboration with other specialized fields
Emergencies defined
Any natural or man made situations that result in severe injury, harm or loss of humans, property and/or environment
Phases of Disaster Life Cycle Model
- Prodromal phase
- Impact phase
- Rescue or emergency phase
- Recovery or reconstruction phase
- Quiescent or interdisaster phase
Prodromal phase
- The warning period when signs or public announcements occur.
- Evacuation or taking shelter may occur in this hose if there is sufficient time
Impact phase
- When the disaster causing event occurs
- May be short (tornado) or prolonged (hurricane)
Rescue or emergency phase
The period when immediate assistance is provided by bystanders and first responders
