Summary of “Chp 41 Terrorism Response and Disaster Management”

This video lecture covers key concepts, principles, and practical guidance for Emergency Medical Technicians (EMTs) responding to terrorism-related incidents and disasters. It provides an overview of terrorism types, weapons of mass destruction (WMD), responder safety, patient care, and incident management in such scenarios.

Main Ideas and Concepts

1. Introduction to Terrorism Response

Terrorism has existed since early civilizations, aiming to intimidate or coerce populations.
Terrorism can be international (outside the U.S.) or domestic (within the U.S.).
Only a small percentage of groups resort to terrorism, including religious cults, political extremists, and lone wolf attackers.
Examples include the Boston Marathon bombing, Pulse nightclub shooting, and other mass casualty events.

2. Key Principles for Responding to Terrorism and Disasters

Emphasize scene safety and situational awareness.
Use the acronym THREAT for managing terroristic events:
- Threat suppression
- Hemorrhage control
- Rapid extrication to safety
- Evaluation (assessment) by medical providers
- And Transport to definitive care
EMS crews may work with law enforcement and wear protective gear like bulletproof vests.
Always stage vehicles safely (uphill, upwind, at a safe distance) and wait for police if uncertain.

3. Weapons of Mass Destruction (WMD)

Mnemonics to remember WMD types:
- BE NICE: Biological, Explosive, Nuclear, Incendiary, Chemical, Explosive
- SEBURN: Chemical, Biological, Radiologic, Nuclear, Explosive
WMDs prefer explosives over firearms for mass casualties.
Types of agents:
- Chemical agents: Vesicants (blister agents like mustard gas), pulmonary agents (chlorine, phosgene), nerve agents (sarin, VX), metabolic agents (cyanide).
- Biological agents: Viruses (smallpox, viral hemorrhagic fever), bacteria (anthrax, plague), neurotoxins (botulinum toxin, ricin).
- Radiological/Nuclear: Dirty bombs (radiologic dispersal devices), nuclear bombs, radiation exposure types (alpha, beta, gamma, neutron).
- Incendiary devices: Used to start fires.

4. Chemical Agent Details

Vesicants cause skin blistering, respiratory tract damage, and eye injuries; no antidote exists.
Pulmonary agents cause respiratory distress and pulmonary edema; treatment is supportive oxygen therapy.
Nerve agents cause SLUDGE/DUMBELS symptoms (salivation, lacrimation, urination, diarrhea, etc.); treated with DuoDote autoinjector.
Metabolic agents like cyanide cause respiratory arrest; treatment depends on availability of antidotes.

5. Biological Agents and Syndromic Surveillance

Biological agents are hard to detect; spread via vectors or direct contact.
Important diseases: smallpox (highly contagious), viral hemorrhagic fever, anthrax (treatable with antibiotics), plague.
Role of EMS includes monitoring clusters of patients with similar symptoms to detect outbreaks.
National Strategic Stockpile contains emergency medications and PPE for rapid deployment.

6. Radiological/Nuclear Incidents

Radiation types vary in penetration and danger; gamma and neutron are most dangerous.
Radiologic dispersal devices (dirty bombs) combine explosives with radioactive material.
Acute radiation toxicity symptoms vary by exposure level.
EMS role: focus on ABCs; decontamination handled by hazmat teams.
Principles to reduce radiation exposure: minimize time, maximize distance, use shielding.

7. Blast Injuries from Explosions

Four phases of blast injuries:
1. Primary: pressure wave damages hollow organs (lungs, ears).
2. Secondary: flying debris causes penetrating injuries.
3. Tertiary: body thrown against objects causing blunt trauma.
4. Quaternary: other injuries like burns or crush injuries.
Explosives often contain nails, glass, or metal shards to maximize injury.

8. Incident Command and Safety

Establish command quickly; EMTs may serve in various leadership roles.
Continually reassess scene safety.
Be aware of secondary devices aimed at harming responders.
Always notify dispatch of event nature, resources needed, and patient numbers.

9. Threat Levels and Public Awareness

Department of Homeland Security issues daily threat advisories using a color-coded system (green, yellow, orange, red).
EMTs should be aware of current threat levels and adjust response accordingly.

Methodologies / Instructions for Responders

THREAT Acronym for Terrorist Event Response:
- Threat suppression
- Hemorrhage control
- Rapid extrication to safety
- Evaluation by medical providers
- Transport to definitive care
Scene Safety and Vehicle Staging:
- Park uphill, upwind, and at a safe distance.
- Wait for law enforcement if unsure.
- Watch for secondary devices.
Patient Assessment and Decontamination:
- Always assume scene is unsafe until proven otherwise.
- Decontaminate patients before contact to prevent cross-contamination.
- Use PPE and trained responders for WMD incidents.
Recognition of Chemical Agent Exposure:
- Identify symptoms based on agent type (blistering, respiratory distress, SLUDGE symptoms).
- Administer antidotes when available (e.g., DuoDote for nerve agents).
- Provide supportive care (oxygen, airway management).
Radiation Exposure Mitigation:
- Limit time exposed.
- Maximize distance from source.
- Use shielding (lead, concrete).
- Do not assume low hazard; treat as worst-case.
Blast Injury Management:
- Assess for primary to quaternary blast injuries.
- Focus on airway, breathing, circulation.
- Prepare for traumatic amputations and penetrating injuries.
Syndromic Surveillance:
- Monitor for clusters of patients with similar symptoms.
- Report unusual patterns to public health authorities.
