The document outlines the critical role of EMS responders in incidents of terrorism, detailing types of terrorism, hazards faced, and essential response strategies. It highlights the importance of scene safety, threat identification, and specific protocols for chemical, biological, radiological, and explosive incidents. The text uses the Boston Marathon bombings as a case study to illustrate response challenges and the heroic actions of first responders.

1. EMS Response
to Terrorism
"I think about the job done yesterday, and tip my hat to the responders,
pray for the victims, and thank whatever forces led me to this calling." -
Michael Morse, rescue captain with the Providence Fire Department

2. Terrorism
● “The unlawful use of force or violence against persons or
property to intimidate or coerce a government, the civilian
population or any segments thereof, in furtherance of
political or social objectives"
● Types
o Domestic - activities are directed at a government or
population, without foreign direction
 Environmental terrorists, Survivalists, Militias, Racial-hate groups,
Extreme political or religious groups
o International -"activities are foreign-based and/or directed
by countries or groups outside the target country or
whose activities cross national borders.”

3. First Responders Role
● EMS is usually principle target of terrorist attacks
o keep safety top priority!
● Isolation
o Incident command and law enforcement's job is to isolate
hazards and organize evacuation
● Notification- potential crime scene
o follow protocols, incident communications may request
additional specialized agencies
● Identification of threat (containers, or specific indicators)
● protect critical assets!
● Gross decontamination (do it)

4. First Responder Role
Count.
● Scene Size-up
o signs of HAZMAT
o Unconscious
o SLUDGEM signs (explained later)
o skin irritants and symptoms
o difficulty breathing
●Situational Awareness
o mass casualties/fatalities with little or no trauma
o responder casualties
o dead animals and plants
●Don't Rush In! (clear scene, PPE, secondary explosive
devices, search all patients)

5. Identify Threat Posed by
Event - OTTO
● potential act of terrorism is crime scene
● OTTO
o Occupancy (location) - Symbolic targets,
public/assembly areas, businesses, infrastructure
o Type of event -scene involves guns, explosions, mass
casualty with no trauma
o Timing of event - holidays, anniversary, public
gatherings, busy times of day
o On-scene warning signs -unexplained patterns, signs,
symptoms, and containers

6. Take Home Message is you
remember nothing else
● Time/Distance/Shielding
o Time - minimize exposure, perform quickly
o Distance - maximize, distances given in Emergency
Response Guidebook
o Shielding - Emergency Response Guidebook for
specific shielding, appropriate PPE, breathing gear,
hide behind cars, buildings, wear HAZMAT suits, get
vaccinations

16. Boston Marathon
Bombings
● responders performed selfless and heroic acts of care and compassion, situation
was special due to large amount of EMS who were on hand for the marathon itself
and were on the scene within seconds, race tents were utilized as cold zone
o Doctors were "pulling ball bearings out of people in the emergency room...a
terrifying scene of shattered glass, bloodstained pavements and severed
limbs." -terrorism expert
o "Somebody's leg flew by my head. I gave my belt to stop the blood" -John
Ross
o "They just started bringing people in with no limbs" -Tim Davey
o "They just kept filling up with more and more casualties...Most everybody was
conscious.They were very dazed." -Lisa Davey
o "This is something I've never seen in my 25 years here ... this amount of
carnage in the civilian population." -Alisdair Conn, chief of emergency services
at Massachusetts General Hospital

17. CNN Report on First Responders

18. We Can't Always Help
● unexploded bombs were rampant Adrian judged scene
was not secure
● The conflict between personal priorities and the call to
duty can be significant
o sometimes we can become part of the problem not aid solution
● "They were disoriented and dehydrated from the race,
and really couldn't talk much...I couldn't do very much for
them, other than stay with them until friends arrived to
help them home."
o -EMT Adrian Will-Orrego, junior at Northeastern

19. Adam Lane
● We had just left the area a minute before the explosion...We could feel the
concussive energy of the primary blast wave
● At first we didn't know what it was...We saw a lot of people run by. It seemed
that it was almost instantaneous that medical responders were all over the
place, tending to the wounded
● I made the right decision to stay with my friends and go help other runners
who were not injured but were still shocked and exhausted by what happened
● You realize after something like this, there is a lot that is just beyond your
control...Had we been delayed a few minutes, things could had been very
different
o -Adam Lane EMT, PA student studying at the Massachusetts College of
Pharmacy and Health Sciences

20. Marathon: IEDs
● Improvised
Explosive Device:
o “homemade” bomb or
destructive device
created to destroy,
incapacitate, harass,
or distract
● wide variety of
forms
● can be thrown,
placed, or
concealed
composed of
● package
o e.g. vehicle, a package, cans,
backpacks, vests etc.
● initiating system
o set off the main charge to make it
detonate
o e.g. cell phone, toy RC, etc.
● main charge
o almost always includes a blasting cap
and batteries
o any type of battery can be used (e.g. 9-
volt, AA, car batteries, etc.)

21. IED Deployment
Triggered
● Over time: allow enemy to
escape or to target victims
● On command: choose the
optimal moment, used against
mobile targets with established
pattern
o include wires or radio
controlled devices
● Victim
o switches include pull or trip,
pressure, pressure release,
movement-sensitive, light-
sensitive, proximity
Deployment Techniques
● disguised in a variety of things
● Multiple IEDs can be linked together with
detonation cord
o charges detonate simultaneously
● often secondary devices and multiple
explosions to increase victims
o scene safety!
● gunfire, small bombs, and other
distraction tactics can bait victims into the
kill zone of a second IED
● Multiple locations are common with IED
bombers so command officers must be
mindful of their resources

22. Specific IEDs
● VBIED: parked vehicle in a high traffic area
● VBIEDS: suicide driver VBIED
o hard to detect and stop
o bomber -mobile, able to choose time, place, and victims

with an explosive vest, belt, or baggage attached to person
o commonly hold up to 12 lbs of explosives (can be as high as 45) and
incorporate fragment materials into the design
o potential attack
 attempting to circumvent security checkpoint or gate
 wearing too much clothing for the weather
 suspicious bulges in clothing
