Chapter 41: Terrorism Response and Disaster Management

Overview

  • Focuses on the EMT's response to terrorism and disaster management.
  • Understanding of weapons of mass destruction (WMD) agents and countermeasures.

Terrorism

  • Definition: Violent acts to intimidate or coerce civilian population or government.
    • International Terrorism: Outside U.S. jurisdiction.
    • Domestic Terrorism: Within U.S. jurisdiction.
  • Types of Terrorist Groups:
    • Religious extremist groups
    • Doomsday cults
    • Violent supremacy groups
    • Cyber terrorists
    • Lone wolf terrorists: Single actor with no external support.

Active Shooter Events

  • Frequent threat in the U.S., difficult to predict.
  • Often involve firearms.
  • Response Plan (THREAT):
    • T: Threat suppression
    • H: Hemorrhage control
    • R: Rapid extrication to safety
    • A: Assessment by medical providers
    • T: Transport to care

Weapons of Mass Destruction (WMD)

  • Definition: Agents designed for mass casualties or damage.
  • Categories:
    • Chemical
    • Biological
    • Radiological
    • Nuclear
    • Explosive
  • Chemical Agents: Blister, choking, nerve, metabolic agents.
    • Vesicans (blister agents): Cause skin blisters, e.g., sulfur mustard.
    • Pulmonary Agents: Respiratory symptoms, e.g., chlorine, phosgene.
    • Nerve Agents: Extremely toxic, e.g., sarin, VX.
    • Metabolic Agents: Affect oxygen use, e.g., cyanide.

Biological Agents

  • Types:
    • Viruses (e.g. smallpox)
    • Bacteria (e.g. anthrax, plague)
    • Neurotoxins (e.g. botulinum toxin, ricin)
  • Dissemination: Spreading the agent; communicability is key.

Radiological/Nuclear Threats

  • Dirty Bomb: Radiological dispersal device causing panic and injury.
  • Nuclear Incidents: Rare but possible; e.g., Hiroshima, Nagasaki.
  • Protection: Time, distance, and shielding.

EMT Response to Terrorism

  • Situational awareness and scene safety are paramount.
  • Use proper protective equipment (PPE).
  • Coordinate with law enforcement and other responders.
  • Follow command structure and reassess scene safety continuously.
  • Decontamination: Critical for chemical and biological agents.

Mechanisms of Injury in Explosions

  • Primary Blast: Direct effects on the body (e.g., hollow organs).
  • Secondary Blast: Injuries from flying debris.
  • Tertiary Blast: Whole body displacement impacts.
  • Quaternary Blast: Other blast-related injuries (e.g., toxic inhalation).

Protective Measures

  • Radiation Exposure: Use shielding, limit time, increase distance.
  • Explosive Devices: Be aware of secondary devices.

Conclusion

  • The lecture emphasizes the importance of preparedness and understanding different types of threats and appropriate responses to enhance safety and effectiveness of EMTs in emergency situations.
