Mass-Casualty Incidents
Due to Terrorism and Disaster
• Risks and responsibilities of operating on
the scene of a natural or man-made
disaster
Introduction
• Terrorist attacks have sharply increased
over the last decade.
− Your personal health and safety should be your
primary concern.
− Additional training and drills can help develop
response skills.
Terrorism
• A violent act dangerous to human life to
intimidate or coerce a government, the
civilian population, or any segment thereof,
in furtherance of political or social objectives
Terrorism
• Terrorism is often
used as a form of
asymmetric
warfare.
• Terrorists tend not
to discriminate
when selecting
their targets.

• Failure to park your
vehicle at a safe
location places you
and your partner in
danger.
Responder Safety
• Responder health and safety can suffer
more than usual during WMD incidents.
− Events can cloud decision making and create
tunnel vision.
Responder Safety

Notification
Procedure/Resource Requests
• As soon as you suspect a terrorist or WMD
event, notify the dispatcher.
• Establish a safe staging area.
• Request HazMat teams as early as
possible.
Command
• If Incident Command System (ICS) is in
place, find medical staging supervisor for
assignment.

Radiation
• Energy emitted
from a strong
radiologic source
has four
categories.
− Alpha
− Beta
− Gamma (x-rays)
− Neutron radiation
Sources of Radiologic Material
• Thousands of radioactive materials found
are generally used to benefit humankind.
− Once it has been used for its purpose the
leftover material is called radiologic waste.
• Remains active but is no longer useful.
Radiologic Dispersal Devices
(RDD)
• Any container designed to disperse
radioactive material
− Generally requires a bomb (dirty bomb)
− Has potential to injure with both radioactive
material and explosives
− Destructive capability is limited by explosives
that are attached to it
Nuclear Energy
• Released by altering or splitting active
atoms
• Results in an immense amount of energy
• Nuclear material gives of all forms of
radiation.

How Radiation Affects the
Body
• Effects vary depending on amount and
route of entry
• Three levels of exposure:
− Radioactive exposure
− External contamination
− Internal contamination
How Radiation Affects the
Body
• Radiation can enter through all routes of
entry as well as through irradiation
• Symptoms of acute radiation sickness
− Nausea
− Vomiting
− Diarrhea
Medical Management
• Exposure to a radiation source does not
make a patient contaminated or radioactive.
− Occurs when radioactive source is on the body
− Must have initial treatment from HazMat
responder before treatment begins
Protective Measures
• To protect yourself from the source, use:
− Time
− Distance
− Shielding
Summary
• You may be called to respond to a terrorist
event. Prepare yourself mentally and
physically.
• Weapons of mass destruction complicate
the management of an incident.
• Terrorism is a violent act to intimidate or
coerce a group to further political or social
objectives.
Summary
• International and domestic terrorist groups
are categorized as violent religious
groups/doomsday cults, extremist
political/social groups, technology or cyber
terrorists, single-issue terrorist groups, and
narcoterrorists.
• NTAS replaced the color-coded system with
threat levels of elevated or imminent.
Summary
• Based on the threat level take appropriate
actions and precautions.
• Clues as to whether an emergency is the
result of an attack include the type of
location, type of call, number of patients,
patients’ statements, and preincident
indicators.
• If you suspect a terrorist or WMD event,
ensure the scene is safe before entering.
Summary
• Notify the dispatcher and inform of the
nature of the event, additional resources
needed, estimated number of patients, and
upwind or optimal route of approach.
• Establish a staging area, keeping in mind
access and exit routes.
• Constantly assess and reassess the scene
for safety.
Summary
• A weapon of mass destruction is any
nuclear, chemical biologic, or explosive
weapon or agent designed to bring mass
death, casualties, or damage to property
and infrastructure.
• Explosives are the most common weapons
of terrorists.
Summary
• Chemical agents include vesicants or blister
agents, respiratory or chocking agents,
nerve agents, metabolic or blood agents,
and irritating agents.
• Exposure to nerve agents is treated with an
antidote delivered as an auto-injector.
Summary
• Biologic agents include viruses such as
small pox and those that cause viral
hemorrhagic fevers, bacteria, and
neurotoxins.
• Standard precautions are extremely
important when treating patients exposed to
biologic agents.
Summary
• Nuclear or radiologic weapons can create
massive destruction.
• Patients who are potentially exposed to
radioactive material must be
decontaminated before contact.
