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, > 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:

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.

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.

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 anticonvulsive 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.
WMD and All Hazards Response
Chemical Threats: Chemical Warfare Agents
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.

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.
Luke’s International Hospital which treated 641
casualties on the morning of the attack with 349 followup cases seen during the next week.

Tokyo Subway Attack
The first EMS request was made at 8:09 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.

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.

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.

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.

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.
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.
