Chemical Threats Accidental industrial chemical
releases Rail
According to the Federal Railroad Administration,
there were 14,264 rail accidents in 2002 -- 59 in
Florida. 704 involved cars carrying HAZMAT in
the US with 13 HAZMAT accidents in Florida. In
1978, an Atlanta St Andrews Bay Railway train
derailed near Youngstown, Florida.  Chlorine gas,
released from a derailed car, killed 8 persons
and injured 138 downwind of the accident site.

Chemical Threats Accidental industrial chemical
releases
Fixed Facility In 1984, a release of methyl
isocyanate in Bhopal, India killed 3,800 persons
40 suffered permanent total disability and
2,680, who lived as far as 25 miles downwind,
were partially disabled. Pipeline In May 2003,
gt 50 tons of anhydrous ammonia escaped after
someone tapped into a pipeline in Brandon, FL.
The leak sent noxious fumes into a subdivision,
shutting down two schools.

WMD and All Hazards Response
Chemical Threats Response
Except for the criminal investigation, a
deliberate release of an industrial chemical
would be handled as a HAZMAT event in the same
way as an accidental release.  Depending on the
characteristics of the chemical, met conditions,
etc., the event may require rapid evacuations and
decontamination. First responders should be aware
that terrorists may plant secondary explosives or
booby traps around the scene of a chemical
release incident.

Chemical Threats Response
The US Department of Transportation (DOT) is
responsible for coordinating the national safety
program for transport of hazardous materials and
for accident response.      DOT publishes the
Emergency Response Guidebook (ERG) that provides
info on identification of hazards, public safety,
emergency response, and initial isolation and
protective actions for over 3000 industrial
chemicals.

Chemical Threats Response Decontamination The Hot
Zone, also called the Exclusion Zone, fully
encloses the Incident site -- the immediate scene
of the terrorist event.   The hot zone will
extend downwind depending on the level of vapor
hazard.  All personnel must be in PPE.
35
WMD and All Hazards Response
Chemical Threats Response Decontamination The
Warm Zone, also called the Contamination
Reduction Zone, is located upwind and preferably
up gradient from the Hot Zone.  Rescue, decon,
and medical personnel are located here and all
must be in PPE.  A triage point is located near
the Hot Zone exit control point for rapid
assessment and further disposition of
contaminated casualties.
36
WMD and All Hazards Response
Chemical Threats Response Decontamination The
Cold Zone, also known as the Support Zone, is
located upwind and up gradient from the Warm
Zone.  All persons working in the Cold Zone
should have respirators available in the event of
a wind shift that would put them at risk for
downwind vapor inhalation.  A second triage
point and a medical aid station may be set up
here to further evaluate casualties for on-site
treatment or immediate evacuation to a fully
capable medical facility.

  • All major chemical releases must be reported to
    the State Warning Point 800-320-0519.  Suspected
    chemical terrorism events, must also be reported
    to the FBI.
  • The National Response Center maintains a
    one-stop point of contact site and hotline number
    800-424-8802 for reporting oil and chemical
    spills -- to include chemical or biological
    terrorism releases. 
  • CHEMTREC established by the chemical industry as
    a public service hotline 800-424-9300 for fire
    fighters, law enforcement and other emergency
    responders to obtain information about emergency
    incidents involving toxic chemicals and hazardous

Sarin (2810) Medical Management.   Depending on
the dissemination method and the dose received,
casualties may require decon, administering of
antidotes, ventilation, and supportive
care.   There are three therapeutic drugs used to
treat nerve agent exposure atropine, pralidoxime
chloride (2-PAMCl), and anti-convulsive drugs
such as diazepam.  In cases of severe nerve
agent exposure, ventilation has been required for
up to three hours.   Long term supportive care
will be required for those with prolonged central
nervous system effects.
45
WMD and All Hazards Response

Sarin Protection  Because nerve agents can cause
casualties from exposure to both vapors and
liquid contact, full respiratory and
non-permeable outer garment protection is
required (Level A Level B).  Decontamination  
Nerve agents hydrolyze under conditions of high
pH.  Hot soapy water solutions can be effective
in removing agent from skin, but complete
hydrolysis occurs over time and run-off from
decon waters may still contain sufficient agent
to cause casualties among unprotected people. 
Skin decontamination is not needed for those who
have only been exposed to vapor only however,
clothing should be removed because it may outgas
trapped vapor.

Chemical Threats Case Study
Tokyo Subway Attack
After numerous failed attempts to
disseminate anthrax spores and botulinum toxin,
in and around Tokyo, on March 20, 1995, members
of the Aum Shinrikyo cult, led by Shoko Asahara
succeeded in releasing sarin in 5 trains running
on three major subway lines converging in
downtown Tokyo.   More than 5,500 people were
affected.  There were 641 casualties resulting
from sarin inhalation that required medical
treatment and 12 deaths.

Chemical Threats Case Study
Tokyo Subway Attack The Tokyo Fire Department
transported 688 victims to area hospitals. The
remainder of the victims were transported by
police vehicle, taxicabs, or self-evacuated to
hospitals on their own.  The nearest medical
facility in central Tokyo was St. Lukes
International Hospital which treated 641
casualties on the morning of the attack with 349
follow-up cases seen during the next week.  
49
WMD and All Hazards Response
Chemical Threats Case Study
Tokyo Subway Attack The first EMS request was
made at 809 a.m. Tokyo Fire Department sent 340
units and a total of 1,364 personnel to 16
stations.
There was no attempt to establish
decontamination.  About 10 of the responding
personnel (a total of 135) were among the injured
after direct or indirect sarin exposure.
50
WMD and All Hazards Response
Chemical Threats Case Study
Tokyo Subway Attack There were 5 patients in
critical condition.  3 arrived with
cardiopulmonary arrest 2 were unconscious went
into respiratory arrest soon after arrival. 
Three were successfully resuscitated.  One
patient did not respond to cardiopulmonary
resuscitation and died.  A second patient was
resuscitated but died on day 28 after the attack
due to irreversible brain damage.   The other 10
deaths occurred at the attack scene.   Those who
died included two station employees who had tried
to remove the bags of sarin.
51
WMD and All Hazards Response
Chemical Threats Case Study
Tokyo Subway Attack 106 casualties (43 men and 63
women, including 4 who were pregnant) were
triaged into the moderate severity category and
hospitalized for overnight observation. Many
complained of headache dyspnea, nausea,
vomiting, muscle weakness, coughing, agitation,
and fasciculation.  Hospitalized patients were
treated initially with 2 mg of intravenous
atropine sulfate and 2 g of pralidoxime chloride
after the agent was confirmed as sarin. 
Intravenous diazepam was administered for
fasciculation.  The remaining 531 casualties had
mainly with eye problems (miosis).  They were
treated with intravenous atropine sulfate,
observed for six hours and released if no other
symptoms developed.  
52
WMD and All Hazards Response
Chemical Threats Case Study
  • Tokyo Subway Attack
  • One month after the attack, St. Luke's mailed
    questionnaires to 610 of those they treated.   Of
    those responding nearly 60 reported post
    traumatic stress disorders.   Many sought the
    services of psychiatrists to relieve their
    psychological symptoms.
  • 32 of the victims harbored phobias related to
    using the subway. 
  • 29 reported insomnia.
  • 16 still had flashbacks of scenes they witnessed
    on the day of the attack.
  • 16 reported depression.
  • 10 reported vivid nightmares.

53
WMD and All Hazards Response
Chemical Threats Case Study
Tokyo Subway Attack Lessons Learned 1. Attack
Effectiveness.  Although the sarin was not pure
or concentrated and the dissemination method was
crude, it created a mass casualty event. 2.
Initially, there was no control possible at the
scene.  Many of those affected self-evacuated to
area hospitals.  Some with mild symptoms chose
not to seek medical attention.   3. Although
Tokyo-area hospitals had emergency and disaster
plans because of the high incidents of
earthquakes, they were unprepared for a mass
casualty incident where all victims were exposed
to the same toxic substance.  
54
WMD and All Hazards Response
Chemical Threats Case Study
Tokyo Subway Attack Lessons Learned 4. There
was no attempt by on scene responders to alert
the hospital or communicate investigation
results. 5. There was no attempt to decontaminate
victims either at the scene or at the hospital. 
Although the major threat from sarin is vapor
inhalation, some of the victims apparently
contacted the liquid sarin or had pockets of
vapor trapped in their outer clothing.  Over 10
of first responders and 20 of the St. Luke's
staff who treated victims developed nerve agent
symptoms that included miosis, ocular pain,
headache, sore throat, dyspnea, nausea,
dizziness, and nose pain.  5. Mass psychogenic
illness and post traumatic stress are factors
that must be considered in the treatment of
weapons of mass destruction attacks in addition
to the treatment of physical symptoms.
