Differences between manmade and natural catastrophic disasters

*    Public panic due to unfamiliar agent

*    Rapid assessment and technical consultation essential and time

*    Close coordination with crisis management essential

*    Law enforcement concerns are significant

*    Demand for health and safety information by public and health
     professionals. Requires prepared messages.

*    Rapid response required to save lives from toxic chemicals and

*    Most first responders have limited knowledge and experience
     with N/B/C/agents

*    Integrated response is required

*    Decontamination of patients and bodies is essential with
     nuclear and chemical agents

*    Mixed agent "cocktail" must be routinely checked for.

*    Worker safety depends on the use of specialized equipment

*    National security concerns are important

                      "A Threat to National Security"
                  Richard Clark, asst. to the President:

Presidential Decision Directive 39: "classified"
"FEMA with appropriate support from other agencies shall review
the FRP to deal with Nuclear/Biological/Chemical incident",
stockpiles and training deficits shall be identified and
resolved. (mentioned NDMS specifically)
                          "Combatting Terrorism"
                     Coordinator for Counter-Terrorism
                              Dept. of State
                        Ambassador Philip P. Wilcox

-    Terrorism: "the use of violence against non-combatants as a
     political threat"

New phenomenon:

Pattern toward mass casualties produced by terrorist acts.
Religious based terrorism, exploit religion or emotion to justify
acts of terrorism.
     -    More difficult to deter

-    Desperate & mentally ill terrorists who live on the fringe of

Use of materials for mass destruction: somewhat scientifically

Copy-cat phenomenon: once the barrier has been breached, what was
once unthinkable becomes reality.

Seven countries that harbor or support terrorism:
Iran           Libya          Iraq
Syria          Sudan          Cuba
North Korea

Better Intelligence is the key to combating terrorism.

Legislative action to decrease funding of terrorism.
     - Counter Terrorism Legislation
     - Strengthen international support of the same

President has issued a directive with a work agenda for the Federal
Govt.: deals with the issues of consequence management

When asked to define the threat and resources planned:
Threat of terrorism internationally has declined, however
terrorists are increasing in their knowledge and sophistication,
their access to weapons is increasing. They have proved that they
can carry out terrorist acts.

                      "Making a big problem smaller"
                              Richard Danzig
                        Under secretary of the Navy

Share and pool knowledge.
Biological threats are more complicated and more challenging
than chemical or other modes of terrorism.

Biological terrorism difficulties:
     -    A weapon of mass destruction
     -    Potent
          -    1 g of anthrax can kill at lethality rates measured
               in millions
     -    Access to biological weapons are better than other modes
     -    Lends itself to attractiveness due to similarity between
          biological weapons and other clandestine activities: ie:
          drug labs
     -    cheap lethality rates (more damage per pound)
     -    Delivery methods
          -    Chemical is easier than other methods
          -    Biological is one of the easiest:
               -    crop duster, fogger, delivered by wind via
                    aerosol dispersion
     -    Ambiguity
          -    Easily disguised as symptoms don't show up
          -    Allows perpetrators time to cover their tracks
          -    Enables uncertainty as to who "started it"
     -    Troops, mass gatherings, etc. occur quickly due to our
          ability to mobilize quickly. This allows opposition to
          deliver biological agents and inflict damage on a large
          number of the responders.

     -    Biological warfare has occurred throughout history
          -    Catapulting plague infected cadavers over walls of
               cities under siege in medieval times
          -    British infecting blankets with smallpox and giving
               them to the indians
          -    Japanese testing biological agents in manchuria
               prior to WWII
          -    Iraq developing biological weapons program

     -    Biological detection is the key, the technology is there
          but $ have not yet been spent on bio-tech weapon

     -    Increased human intelligence, increased knowledge of
          biological threat through inter-personal contacts

     -    Example of contact with one chemical agent: Ricin
          -    Potent
          -    Produced by common household chemicals and easy to
          -    Found by a highway patrolman and eventually
               analyzed and discovered: was going to be used by a
               drug gang toward a rival gang
          -    In minnesota: ricin was developed and brought into
               a local police dept in a coffee can.
What's being done:

     -    Military developing a Marine unit (2000 persons)
          specially prepared to deal with biological threats.
          Focused for 6 month deployments abroad (mediterranean).
          Although not geared toward domestic response, lessons
          learned will help domestic response units.

     -    Every agency needs to develop a crisis response unit that
          has a deeper knowledge of the biological / chemical agent
          threat, analysis and response

     -    Antibiotic "cocktails" and immunizations can provide a
          measure of protection against some agents if the threat
          is imminent or expected.

     -    Detectors: investment in this technology is sparse

     -    Education in personal protective equipment (PPE) use

                         "FBI Terrorism Briefing"
                                John O'Neil
                       FBI Counter-Terrorism Section

-    There is no law that makes terrorism illegal: ie:
     -    no law against transfer of biological hazards other than
          laws such as mail fraud, etc.

-    FBI's role in Terrorism Arena
     -    Designated by Pres. Reagan to be lead agency in US
          against Terrorism:
     -    FBI can under the auspices of Dept. of State can protect
          citizens overseas
     -    Lead crisis agency for the Feds

-    Terrorism categorized as:
     Domestic Terrorism
     -    Those individuals indigenous to US and not controlled by
          foreign power
     International Terrorism
     -    Persons controlled or supported by foreign powers

-    FBI Mission:
     -    Prevent acts of terrorism prior to occurrence
          -    Intelligence & surveillance
          -    Strengthen the targets of terrorism against
               terrorist acts
     -    Swift and robust action against terrorist act after the
          -    Seek out and prosecute terrorists
         -   Continued tracking and evidence collection of past
             terrorists and terrorist acts

-   Terrorists are more interested in large scale terrorism with
    mass casualties:
    -    World Trade Center
    -    Oklahoma
    -    Japan (gas)

-   As a result of World Trade Center & Oklahoma bombing:
    -    need to put pressure on countries that support terrorism
    -    focus more attention on religious or other fanatics and
         trans-national movements
    -    became aware of organizations that seek funds and
         donations to support terrorism abroad (Israeli peace
    -    Special interest groups and right-wing groups
         -    Anti-Abortion, Environmental, Animal Rights, and
              special interest groups who have political agendas
         -    Militias, white supremacists, etc.
              -    behavioral science section of FBI does
                   outreach to these groups

-   Events that fire the Radical Extremist movements:
    -    Shaw of Iran downfall
    -    Anwar Sadat killed
    -    Bosnia, Sudan, etc.
    -    Vatican re-opens diplomatic ties with Israel
    -    Anniversary dates of other events

-   Preparation for special events: Olympics, Pope visit, etc.
    -    "inside the center of olympic village is a working Nuc.

-   Threat assessment component:
    -    grouping of behavioral sciences, PHS, FEMA, FBI Lab, etc.
    -    EG: video received by a public facility that indicated a
         threat to that facility during a mass event
         -    team assessed the threat and personnel were
              deployed to protect that facility
    -    Uses the joint command center

-   100 person hostage rescue team out of Quantico:
    -    Trained in personal protective equipment use and can
         execute their law enforcement role while protecting
         themselves against N/B/C threats

-   Various table-top and field exercises are being developed to
    train FBI and other agencies for N/B/C hazards

-   In the event an agent has been disbursed, the command of the
    response would shift from the senior FBI field officer to
    FEMA. The focus of the response would shift from law
    enforcement to consequence management. Law enforcement would
     still continue but would not hinder rescue or other responses
     to the consequence.

        "Concerns over chemical and biological dual-use technology"
                             Robert D. Walpol
              Deputy Director, Non-Proliferation Center, CIA:

Non-Proliferation: 4 aspects to US strategy
     -    Prevent acquisition of the technology
     -    Roll back program that generates that technology
     -    Deter use of the technology
     -    Adapt military and other existing resources for response
          to the use of the technology

-    Agent used for terrorist act depends on the terrorists intent:
     -    The intent of their act will determine what weapon they
          choose as each has a different effect

-    Chemical Weapons Convention:
     -    Libya & Iraq have refused to sign it, Iran signed it but
          does not comply
     -    Iran:
          -    Develops mustard and other choking agents
     -    Iraq:
          -    develops many chemical agents that can be delivered
               by numerous means
     -    Libya:
          -    Many agents and numerous facilities for Chemical
               Weapon production and delivery

-    Biological Weapon
     -    Cheap: so used by developing countries
     -    uses dual use equipment and supplies
     -    manufacturing of other legitimate agents can mask
          production of biological weapons (can be hidden from
          international inspectors).
     -    Shift from legitimate agent production to Bio-weapons can
          be done in a matter of days to weeks
     -    Delivered by off the shelf equipment (garden sprayers)
          rather than conventional weapons delivery systems
     -    Iran:      end of development stages of Research &
                     Development of Bio-weapons
     -    Iraq:      maintains an aggressive Bio-Warfare program
     -    Libya:     lacks biological technology and sophistication
                     to make Bio-weapons

              "Medical Aspects of Biological Warfare Agents"
                      LTC Edward Eitzen, MD, US Army
Biological Warfare: the use of microorganisms or toxins derived
from living organisms to produce death or disease in humans,
animals or plants

     -    unicellular organisms
     -    vary in size, shape
     -    under special conditions some can be transformed into
          spores: resistant to cold, heat, desiccation
     -    cause disease by invading the body tissues

     -     smaller than bacteria
     -     require a host cell in order to multiply

     -     products of living organisms that adversely effect other
           animals or plants
     -     not man-made

Bio-Weapon Characteristics:
     -    dispersed by aerosols and not visible
     -    silent, odorless, tasteless
     -    relatively inexpensive to produce
     -    may be unpredictable
     -    simple technology for delivery available
          (sprayer attached to any vehicle)
     -    user could tailor choice of arsenal to fit needs
     -    terrain and physical structures are usually spared
     -    may be easily used in combination
     -    used with other forms of warfare
     -    large area coverage capability (100's of miles)
     -    create fear, terror and panic

Lethal vs. Incapacitating Agents

Lethal         Incapacitation
Anthrax        Vee Virus
Ricin Toxin

Hypothetical dissemination by airplane of 50kg Anthrax along a 2km
line upwind of 500,000 people

agent                 downwind    dead        incapacitated
-------------------   ---------   ---------   -----------------
rift valley fever     1           400         35000
typhus                5           9,500       35000
anthrax               >20         150         125000

Routes of exposure to Bio-Weapons
     -    Inhalation
          -    most significant route
          -    invisible clouds of small droplets (10 microns)
          -    Large droplets >10 microns are filtered or drop out
               of the air
          -    Smaller than 5 microns are delivered to alveoli and
               absorbed systemically
          -    same disease via lung as when ingested
     -    Oral
          -    Potentially significant route of delivery
          -    contamination of food or water supplies either
               purposefully or accidentally
          -    unlikely that an aerosol attack with toxins would
               significantly contaminate water supplies
          -    direct contamination of water supplies by pouring
               toxins into the water would require that it be done
               downstream from the processing plant
          -    Usually the body of water itself, dilutes agent
     -    Dermal
          -    Intact skin provides an excellent barrier for most
          -    damaged skin (abrasion) makes it more likely to
          -    intradermal injection: ricin poisoning of bulgarian
               defector Georgi Markov by pellet from the end of an

General Preventive Measures
     -    Physical protection
          -    most important
          -    prevent exposure with full face respirator
               (respiratory tract and conjunctiva)
          -    surgical masks not effective
          -    need to decontaminate yourself prior to removal of
               protective equipment
     -    Decontamination
          -    dermal exposure should be treated with soap and
          -    dilute chlorine or bleach for 10-15 minutes
     -    Vaccines
          -    civilian population are not routinely vaccinated
               foremost Biological Warfare agents
     -    other drugs:    prophylaxis
               -     secondary exposure protection

Post Exposure Management
     -    Anthrax
          -    Prototype Biological Agent
          -    Vaccinate immediately and antibiotics
          -    antibiotics for 12-16 weeks if not vaccinated
          -    primarily occurs in herbivores
          -    reservoir is in the soil
          -    person-to-person transmission does not occur
          -    Problem in: Pakistan, Iran, Sudan, Haiti
    -   Easy to make and cheap
    -   Short incubation period
    -   small number of spores to create infection
    -   spores are very hearty
    -   produces toxins that are responsible for most of
        anthrax's lethal effects
    -   Cutaneous form (95%)
        -    papule on skin that enlarges into ulcer
             surrounded by vesicles, swelling
        -    treatable with antibiotics
    -   Gastrointestinal
        -    ingestion of infected animal products
        -    high mortality rate >50%
    -   Pulmonary
        -    doesn't infect the lung but is absorbed by
             lung, picked up by lymph system and infects
             the mediastinal lymph glands, breaking down
             the mediastinal organs
        -    incubation for 2-5 days with sudden onset of
             cardiorespiratory symptoms: hemorrhagic
             mediastinitis, pulmonary effusion, etc.
        -    Chest Xray shows widened mediastinum as a
             clinical hallmark
    -   Anthrax vaccine available with very minor side
        effects: 3 doses over 4 weeks
    -   Dual treatment of antibiotics (Cipro) and vaccine

-   Botulism
    -    Affects the neuromuscular junction similar to the
         way a nerve agent would work, but in the opposite
    -    Food born most prominent due to improperly prepared
         food. Most common form affecting infants, fed
         milk, etc. Infant cant break down and combat the
         botulin toxin.
    -    Wound botulism is rare, infects open wounds and
         produces botulin toxins that have a systemic
    -    Inhalation botulism occurs
    -    Onset of symptoms 24-36 hours to several days after
    -    Descending paralysis: cranial nerves first
         (drooping eyelids), last symptoms being muscular
         paralysis and respiratory paralysis
    -    Senses are not effected, so although paralyzed,
         victim is aware of what is going on
    -    Can be confused with Myasthenia Gravis, Guillain-
         Barre, Organophosphate, nerve agents poisonings
         given too much atropine
    -    Vaccine available (investigational new drug)
         -    takes 12 weeks
    -    Management:
         -    ICU type care (ventilatory, etc)
         -    Anti-toxin is available but has secondary
                   risks due to it being a horse serum (allergic
                   rx): must be given prior to toxins being
                   absorbed into the nerve endings

    -    Ricin:
         -    Castor bean plant
         -    Used to kill Georgi Markov (Belgian defector)
         -    Cyto-toxic: severe necrotizing process to all cells
              it comes in contact with
              -    Lung, GI tract, etc.
         -    Causes Pulmonary necrosis, effusion, etc.
         -    Ingestion causes severe symptoms in 8-10 hours,
              abdominal cramps, hemorrhagic processes to mucus
              membranes and death within 2-3 days
         -    No specific medical therapy. Supportive management
              usually ICU required. Activated charcoal can be
              used for GI exposure if used within the first 1-2
         -    Prophylaxis: physical protection
         -    Vaccine not yet available

    -    Staphylococcal Enterotoxin:
         -    Same as those that cause GI infection
         -    When inhaled cause severe problems and
              incapacitates for a couple of weeks: usually not
         -    Complex interaction with immune system: super-
         -    3-12 hour onset of symptoms
         -    High fever (103-106), SOB, N/V/D
         -    Diagnosis is epidemiologic
         -    Medical management is supportive
         -    No vaccine available

    -    Need to determine if a situation is an endemic infection
         or a Biological Attack
         -    Bio attack
              -    Increased number of victims than typical
              -    More respiratory exposure than normal
              -    Multiple or mixed attacks
              -    Exposure in a non-endemic area

    -    Impact on medical infrastructure
         -    overwhelming casualties and demands on ICU care
         -    barrier nursing (masks, gowns, etc)
         -    Agent dependent

                     "Potential Incident Scenarios"
                           William C. Patrick
                          BioThreats Assessment

-   Meteorology:
     -      Inversion layer that keeps smoke and dispersal on the
            -    most often occurs during early morning and at night

-    Munitions efficiency: number of infectious units rendered
     airborne in the 1-5 micron size

-    New york subway system: thrown from the back of trains
     -    Egland Air Force Base:
          -    Disseminated bacilli and infected base housing and
          -    Didn't need to get close to the security perimeter

Amount of Agent (kg) to produce 50% casualties on 1.5 KM^2 target:

     Anthrax    0.09
     SEB        78
     Botulism   512

14 story building attacked with 8g of bacilli
     -    introduced into ventilation system
     -    penetrated all floors of bldg in 15 minutes
     -    remained viable for 5 hours

Success of attack:
     -    Size of bldg in liters
     -    Man breathes 10L per minute
     -    number of doses of agent

World Trade Center scenario using various toxins:
     -    10 billion liters of air
     -    Grow botulona Toxin in garbage cans
     -    would need 264 gallons of toxin to spread through bldg.
     -    Botulana toxin requires more strength for pulmonary route
          and thus would not be feasible
     -    however, if you use dried botulana toxin, the volume
          required is only 1 kg of material to produce an effective
          dose in 1.2 hours
     -    Tulleremia would produce an infectious dose after 20

Dedicated   Terrorist Group:

                               "Chemical Agents"
                             Fred Sidell, US Army
              Medical Research Institute for Chemical Defense

Chemical agents are not new:
     -    13th century was the first. greeks used during the 14th
     -    Cyanide shells used during WWI
     -    Chlorine shells used during Civil War
     -    WWI Germany used Chlorine gas, 1/3 of the casualties
          involved chemical agents
          -    CN tear gas, Chlorine, Phosgene, Cyanide, Mustard
     -    Since WWI: Nerve agents, CS tear gas

Physical Forms:     Gas, vapor, aerosol, liquid, solid

Chemical Hazard
     -    non-persistent (hours)
          -    vapor
          -    liquid: evaporation
     -    Persistent (1 day to years)

Agents of concern:
     -    Nerve Agents
     -    Vesicants
     -    Cyanide
     -    Phosgene and related
     -    Riot control
     -    Incapacitating agents (makes one unable to function
          normally for a period of time with a full recovery)
          (loss of vision, dizziness, GI upset)

Vesicants of Concern:
     -    Cause vesicles or blisters
     -    Mustard
          -    Chemical warfare Agent
          -    Synthesized in 1822
          -    Low lethality (<5%) causes lots of casualties
          -    100th of lethal amount will cause eye damage
          -    10mcg of liquid will cause a blister
          -    Skin, eyes and airways are affected, causes damage
               in bone marrow, CNS and GI tract
          -    Absorbed in minutes: action must be taken within
               minutes as effects are irreversible
          -    Clinical effects occur 2-48 hours later (4-8 hours
     -    Luicite
          -    similar effects to mustard
          -    Causes immediate pain
          -    very irritating to eyes and mucous membranes
     -    Cyanide
          -    effects within seconds
          -    burning plastics contain cyanide
          -    small amounts can be detoxified
          -    High amounts needed for lethality, no effects at
         lower doses
    -    Inhibits intracellular enzyme that helps cell use
    -    Ingestion:
         -    Vertigo, nausea, weakness, respiratory &
              cardiac depression
         -    Antidote very effective if given soon after
    -    Inhalation
         -    death in 5-10 minutes
         -    Not effective outside due to dispersion
         -    Effective in confined space
    -    Antidote: amyl nitrite
-   Nerve Agents
    -    Inhibit cholinesterase allowing toxic buildup of
    -    Carbamate (insecticides)
    -    Organophosphate (malathion)
    -    Tabun(GA), Sarin(GB), Soman(GD)
    -    Colorless, odorless, tasteless
    -    Penetrate skin and clothing very well (not safe
         with just a gas mask)
    -    Volatile and evaporate readily (but less quickly
         than water)
    -    Vapor hazard
    -    Lethal dose is quite small (10mg for VX)
    -    Glands hypersecrete, muscle stops contracting,
         bronchial constriction and hypersecretion, vagal
         stimulation of heart, CNS effects from confusion to
         death which may linger weeks
    -    Atropine only effective on muscarinic effects
         (muscles, secretions)
    -    Initial effect depends on amount of exposure
    -    Skin exposure: small drop = localized sweating and
         fasciculation, larger drop = GI effects, Large drop
         = CNS effects and death within a few minutes
    -    Management:
         -    Decontamination
              -     Skin decontamination only worthwhile if
                    within minutes of exposure (skin
                    decontamination will help to protect
              -     Most victims of nerve gas are exposed
                    only to vapor and no decontamination is
         -    Ventilate: will have very high airway
         -    Atropine: has side effects and doesn't correct
              nicotinic effects (skeletal muscle paralysis)
              -     2mg effective dose (self-administered)
                    with up to 20mg total dose for severe
         -    Remove agent
              -     Oximes: help with nicotinic effect

                           James A Genovesse
                    US Army R&D Engineering Center

-   "$30 shop-vac is a good disseminator for chemical agents"
    -    good example of a simple piece of equipment that can be
         purchased anywhere and used for chemical dispersal

-   Chemical vapors:
    -    All get into the deep lung and can be absorbed
    -    Work well in closed environment

-   Focus: chemical incidents involving volatile chemical agents
    in close quarters

-   Comparing Terrorism to Military Operations:
    -    terrorism targets are non-combatants
    -    minimal civilian training and preparedness
    -    open field engagement vs. covert, close quartered
    -    terrorism evokes psychological and physical response from
         its victims
    -    Infinite number of scenarios (targets) possible

-   Why chemical terrorism?     IT'S EASY TO DO !!

-   Easiest cloud to generate
    -    Almost independent of dispersion method
    -    Gaseous molecules - well behaved - high rate of diffusion
    -    Rates of droplet evaporation
         -    Particle size
         -    Number density
         -    Heat of vaporization
    -    Already in respirable range

    -    Easy to get
    -    Nerve Agents:
         Sodium Fluoride + Methyl Phosphonic Dichloride +
         Isopropyl Alcohol = Sarin
         -    Commercially available
         -    Methods to make agents available on the Internet,
         -    Malathion / Parathion: readily available and about
              1/10th the toxicity of Sarin (GB)
         -    Industrial hazards commercially available:
              Chlorine, Phosgene, Methyl Isocyanate, Hydrogen

    -    Environmental mixing - outside
         -    Winds
         -    Solar heating
    -      Large "atmospheric" mixing bowl
    -      hence:
           -    Concentration rapidly decreases
           -    Lethality low

-   Environmental mixing - inside
    -    Physical barriers (walls)
    -    Forced air currents
    -    No wind and no infinite source of air
    -    Comparatively little dilution
    -    hence:
         -    concentration remains lethal for longer
    -    Commercial buildings have air intakes, personal
         houses usually get their fresh air from diffusion

-   ie: Cruise ship
         -    where do you evacuate to ?
         -    closed system

-   Why explosive dissemination ? (what the terrorist knows):
    -    Old wives tail: Chemical / biological material is
         consumed in the fireball - Not true
    -    Chemical / Biological material rides the shock wave
         ahead of the fireball
    -    Instant gratification for the terrorist

-   Pyrogenic agent generation: ie: Cigar dipped in teflon
    -    Produces Phosgene, Hydrogen Fluoride, sub-micron
         polymeric fumes (.01 micron particles), not
         recognized by alveolar macrophage thus absorbed
         interstitially (Hold what's absorbed in them for
         weeks until they degregate and then release the
    -    As more building materials are polymeric, when
         burned they release more toxic agents

-   What   is needed to cover a chemical incident
    -      Early detection
    -      Respiratory protection
    -      Consequence management education
    -      Responsive medical treatment
    -      Hazard prediction & analysis

-   Summary
    -    Chemical incidents are easy to accomplish
    -    Effective, lethal alternative to conventional
    -    Training and education are mandatory
    -    Blower masks (made by Israel company) are excellent
         public protection devices

        Allan Holmes, Asst. Secretary of Defence for Special Ops
-   "A nuclear/biological or chemical terrorist is no longer
    beyond the imagination"

-   15 Countries known to have offensive Chemical weapons programs
    "the poor mans atomic bomb"

-   Advantages to conventional weapons: widespread death &
    destruction, built in hostages, news media coverage, allow for
    covert acts (death hours after, mis-identification), Terrorist
    knows: probability of a response in kind is low (he controls
    the lethal action)

-   Some of our allies find it difficult to comply with threat of
    terrorism because they are afraid of becoming a target

-   Even when State sponsorship is suspected it is difficult to
    prove and thus difficult to retaliate.

-   Cooperation between Fed, State & Local authorities is the most
    -    Cant use military domestically
    -    most assets to combat chemical/biological weapons are in
         the military

-   Crisis managers must rely on responders who can do mass care
    and cleanup:
    -    planning and actions of crisis managers can inadvertently
         affect rescue and cleanup efforts and thus must be
         closely coordinated
    -    Warning, detection, identification, rendering safe, final

-   US has three courses of action
    -    Maintain status quo:
         -    assumes that terrorists wont use c/b weapons

Questions posed to residents:
1st questionnaire: 3 weeks after incident
-    471 had subjective symptoms
-    40 Admitted to hospitals
-    156 visited Out Patient clinics
-    277 did not consult MD

at 4 months
-    55 had symptoms

-    Analysis of questionnaire showed correlation between wind
     direction from release of Sarin to reports of symptoms from
     those who returned the questionnaire

-    Casualties of Rescue Teams
     -    18 teams, 52 persons from 5 departments
     -    8 persons complained of symptoms, 1 admitted to hospitals
          for one day
     -    Wore no protection for gas or toxins
     -    Staff who developed symptoms worked early in the incident
     -    Rare symptoms from personnel at hospital, meiosis was

The agent identified as Sarin (GB)
-    Compared with Hydrogen Cyanide, Halogenated compounds
     (Hydrogen Fluoride, HCL), Organophosphate, Phosgene
-    Identification of sarin was not possible from medical exam, it
     was only Identified after chemical detection
-    Sarin, byproducts of manufacture, or degradation products of
     sarin were detected in all of the dead victims

-    Less than 20 liters was deployed
-    Deployed from a truck with a heater and fan
-    Perpetrators were poisoned and treated by the terrorists

-    did not use many oximes for treatment
     (were used and were effective in subway gas attack)
-    Information exchange system
-    Registration system of casualties
-    20L or less was released
-    Casualties lived 400m downwind from release
-    Deaths lived 80m downwind
     -    All dead victims had window open due to weather
     -    None were on the first floor, all were 2nd or 3rd
          -    1st floor keep windows closed for safety
-    Symptoms observed were all typical of sarin
-    a large number of rescue team experienced symptoms who worked
     during the early part of the response
-    Not many people displayed psychological (psychogenic) symptoms
    -    The cause was unknown until later

                         "Japan Subway System"
                   "Japanese medical team briefing"
         Dr. Sadayoshi Obu, St. Luke's International Hospital

-   Subway station involved was at the juncture of 3 lines
-   5500 passengers and employees sickened, 11 deaths
-   Converted chapel to observation area (22 patients held
    overnight in the chapel for observation)
-   08:16 first call to Emergency      08:32 first critical victim
-   by 14 :00 all ambulatory patients were evaluated (650 victims)
-   5 patients in critical condition (3 in Cardiopulmonary arrest,
    one of which expired (meiosis remained even after death), 1
    had brain death and expired 28 days later, 1 who responded
    after 5 minutes of resuscitation)) 2 were admitted in drowsy
    condition, went into respirator arrest and then treated and
    responded. (both were discharged from ICU in 4-5 days)
-   PAM (oxime) was used in most of the critical patients
-   111 patients (45 males / 66 females (5 pregnant)) were
-   80 were discharged the next day (within 24 hours)
-   Within 24 hours all hospitalized patients were given Atropine
    and PAM (after diagnosis of SARIN was received 3 hours after
    attack), all received IV rehydration.
-   Patients could have been managed without PAM, however Serum
    Cholinesterase levels returned to normal faster than typical
-   A small percentage of hospital staff had symptoms (meiosis and
    other visual problems)

-   Sarin used in this attack was dilute

-   Factors that made response to this attack successful?
    -    Preparedness for disaster: frequent drills and practice
    -    Faculty design: had non-medical area that was used for
         holding / waiting
    -    Time of day (just prior to busy working day) which
         minimized victims
    -    Demographics of victims (young and middle aged) no very
         young or elderly
    -    Isolated injury: no trauma or other injuries
    -    Police suspected the incident, the terrorist group
         preempted their planned strike. Government had
         stockpiled PAM and Atropine incase of an incident

         Dr. Tatsuo Yamaguchi, St. Luke's International Hospital
Ocular symptoms of Sarin Gas incidents in Tokyo:

-    Anatomy of eye:
     -    Anterior chamber:   controls eye pressure by secretion of
          vitreous humor

-    07:50 incident occurs
-    08:28 first patient arrives (hospital 5 minutes away)
-    08:50 first patient arrived in ophthalmology dept,
-    09:00 Ophthalmologist sent to ER
-    09:40 Acetonitrile was determined to be agent
-    11:00 Sarin was determined, cholinesterase level was examined
     on all patients
-    11:30 symptoms and treatment for SARIN faxed to St. Lukes from
     Tokyo Ophthalmology Assoc. (sent also to other area hospitals)
-    14:00 patients showing light reflex
-    17:00 all 112 outpatients with ophthalmologic problems were
     sent home with D/C instructions to return for problems
     (saw 112 victims of the attack along with regular appointments
     of 185 persons)
-    1 day later: 138
     2 days later: 139
     3 days later: 81
     4th day: 100
     total 480

-    Treatment for meiosis
     -    Mydrin-P: 4-5 hours   (preferred)
     -    1% Atropine: 5-7 days
     -    1% Cyclogyl: 6-24 hours
-    Meiosis lasted days
-    ciliary injection / conjunctival congestion / constricting
     visual field / changes in accommodation

-    Anterior Chamber showed edema
-    Electro-Retinal-Gram (ERG) showed decreasing of the A & B

-    3 months after incident: 41 patients reviewed (17 admitted, 24
     -    15 still had eye complaints
     -    16 had systemic complaints
     -    1 had psychological complaints
     -    Meiosis in 28 patients
     -    None experienced new blindness
     -    2 had increase in corneal thickness
     -    13 had abnormality in ERG

-    Treatments used:
     -    Miosis
     -    Hyperemia
     -    Foreign body sensation

-    Long term follow-up is needed in these patients even though
    symptoms are not severe.

                        US Medical Team Briefing
         Fred Sidell, US Army Medical Research for Chem Defense

-   Cited example of victim who after the subway incident, hailed
    a taxi and traveled to hospital, kept clothing on and was not
    decontaminated: potentially could have contaminated the taxi
    and other areas as she came within 6 feet of the SARIN.

-   US Govt. Team of:
    Scott Lillibridge, Sanford Leffingwell, John Liddle, Frederick
    -    In Tokyo for two days, 1 afternoon at St. Lukes hospital
    -    5510 casualties: 12 deaths, 17 critical (required ICU),
         37 severe (had GI complaints), 984 moderate (has meiosis)
         -    ~1400 patients that went to hospital and had
              nothing wrong

    -    4073 patients seen on day one and not hospitalized,
         dozens came during the next 48 hours who thought they
         were exposed.
         -    80 % of the casualties reported had no chemical
         -    Incidents of those who are scared and uninjured may
              be quite high and hamper access to those who are
              actually injured.

    -    Should antidote be administered via auto-injector on site
    -    Those physically exposed to an agent must be
         decontaminated, those who are exposed only to vapor may
         not need to be.

    -    Treatment:     Atropine (0.5mg q 15 minutes) use pupil
                        size as indication
                        Pralidoxime (1g q 8 hours)

    -    Why few deaths?
         -    Single source
         -    Slowly evaporating
         -    No dissemination
         -    People left quickly
         -    Factors caused low dose in most

"State of the art terrorism: lessons learned from the tokyo
subway attacks"

-    8am monday morning March 20, 1995:
-    Similar attack in Matsumoto: June 27th, 1994
     -    No political, military or symbolic significance
     -    Nobody claimed responsibility
     -    Released at night in a residential neighborhood
-    Kamakuishiki in July 1994
     -    HQ of Aum Shinrikyo sect with factories and dormitories
     -    Cult members seen ill and claimed they were targets of
          chemical weapon attacks
-    Other similar events of gas and suspicious items
     -    Noxious chemical around Tokyo released in a train
     -    Tokyo: 3 briefcases found with a fan, battery operated
          and was releasing a gas (unidentified)

-    All these events indicated that someone was experimenting and
     testing techniques for a terrorist act

-    Plan:
     -     Place sarin on five trains, all converging on the center
           of tokyo
     -     Plan was to involve a large number of deaths and injury
     -     One delivery man, one "puncture" man who activated the
     -     15 stations affected

-    Japanese authorities had planned a raid to attack the sect and
     raid their locations
     -    Training in PPE and hazardous chemicals for police
     -    Raids and arrests occurred very fast (2 days) after
     -    Found a number of chemical and biological substances in
          raided establishments

-    The cult has a number of branches in other countries:
     -    Sarin was tested in Australian site prior to incidents in
     -    Successful in attracting Scientists
     -    Most leaders were college educated
     -    Did have business arrangement with the Japanese mob

Since March 20th, 1995
-    At least 5-6 subsequent attacks on train stations
-    3 incidents of Cyanide gas devices that were disabled prior to
     "going off" (some are very sophisticated)
-    Significant media attention in Japan
-    Continuing public fear
-    Public demands for changes in the system

-    Specifics about Tokyo Sarin
     -    Manufactured with the German Salt process
     -    not distilled: ~25 % pure
     -    Acetonitrile (solvent) used to activate
     -    Produced in swiss-built chemical synthesizer
          -    Purchased in Tokyo
          -    Used to prototype chemicals
          -    possibly used an american software package
     -    Produced two days prior to the attack
     -    Less than 24 liters of the chemical
     -    Other chemical agents were made: VX, TABUN, Mustard,
          Cyanide compounds
          -     two assassination attempts with VX by cult
     -    Delivery system was very crude
     -    Two Japanese transit workers died trying to move chemical

-    Reasons for attack?
     -    Attempt to deter Police who the cult realized were close
          to raiding their establishments (warning)
     -    Fulfillment of a prophecy (doomsday)
     -    "kids with matches", novel curiosity about the deadly
          aspect of the gas attacks

-    Could have been worse?
     -    Satyam7 (cults dedicated sarin production plant)
          -    never successfully operated
          -    designed to manufacture thousands of kilo's of sarin
          -    Included a distillation column
          -    Possibly had problems with leaks (plastic on floor,
               bucket to catch drops) and could have contaminated
               the area during production
     -    Previous unsuccessful attempt to produce botulin toxin
          and aerosolize it
     -    Had a truck with large air compressor and hidden vents
          and two helicopters with spray apparatus that could have
          been used for dispersal
     -    Nuclear option
          -    Cult had a russian connection
          -    Obtained access w/ frequent travel to Russia
          -    Notebooks captured by police made reference to
               various nuclear devices
          -    Had attempted to obtain land where uranium could
               have been mined

     -    Still 8 cult leaders out on the street
     -    Followers are trying to salvage business holdings

What Tomorrow?:
     -    Others will learn the lessons of tokyo and use CW or BW
          and use them with greater effectiveness.
     -    The taboo has now been erased after the first event

Genetic Evolution:
Host-parasite co-evolution
Co-adaptation to mutualism or accentuation of virulence?? Jury is
still out. (May & Anderson) Many zoonotic convergence. Probably
divergent phenomena, with short term flair ups and pyrrhic
victories, atop long term trends to co-adaptation

          -    Potentially unlimited capability; bacterial
               metabolism and genetic structure
     -    Anti-viral Chemotherapy

Influenza as a prototype:
     -    Has periodic outbreaks and accounts from 5-7 % of deaths
          -     mostly to elderly and young
     -    Genetic re-assortment is accountable for rapid shifts in
          antigen characteristics
     -    1918: a variety of influenza that was similar to Hanta-
          Virus and was probably the result of a particularly
          virulent strain (SWINE FLU)

-    Distinction between Terrorist usable substances and those

NIH has identified:
-    About 400 viruses that identified as hazardous and need
     extraordinary precautions
-    a couple dozen that require extreme precautions and have
     caused death or serious illness to a researcher
-    Fortunately it requires sufficient sophistication to isolate
     and culture these viruses so as to make most of these not
     usable for terrorists

In the year 1346, Caffa was again besieged by the Mongols. During
this same time, a vast epidemic of bubonic plague had rapidly
spread through the Mongol empire. In the words of Gabriel De
Mossie, a contemporary chronicler, "the Tartars, fatigued by such
a plague and pestiferous disease, stupefied and amazed, observing
themselves dying without hope of health, ordered cadavers placed on
their catapults and thrown into the city of Caffa, so that by means
of these intolerable messengers, the defenders died widely"

-   Look at the history of recent events and it is obvious that
    there is a problem

-   Consequence managers must be responsive to plans for managing
    a chemical / biological incident as well as emerging diseases

-   The problem is now on the scope of the highest level policy
    makers in the country
    -    They will be coming to us for more information and help
         when the policies are going to be written

-   PDD 39: Response to weapons for mass destruction
    -    US will be prepared to respond
    -    US will work with other countries
    -    Policy making being pushed down to the agencies that are
         most involved

-   Enhancing the field of intelligence and information on Foreign
    chemical / biological weapons programs and networks to obtain
    pre-cursors and equipment for their manufacture

-   Training and educational programs are key all the way down to
    the "front line" level
    -    Tap into the US military training for improving domestic
         response capability
    -    Exercise at all levels (including the state and local

-   Better communication & coordination between Federal, State and
    Local agencies

-   Equipment development (detection, warning, decontamination,
    etc) need to be further developed

-   More investments in Antibiotics, vaccines, other therapies and
    the stockpiling of such
