  1. CATEGORIESTerrorist Incidents • Biological • Nuclear • Incendiary • Chemical • Explosive

  2. T-D-S

  3. BIOLOGICAL AGENTS Pose a serious threat due to their accessibility, potential for rapid spread, and ability to cause multiple casualties. Routes of Entry Inhalation Absorption Ingestion Injection

  4. COMMON BIOLOGICAL AGENTSMost likely routes of exposure are inhalation and ingestion Bacteria Rickettsia Viruses Toxins

  5. BACTERIA & RICKETTSIA • Bacteria: single-celled organisms • Multiply by cell division • Rickettsia: smaller than bacteria • Live inside individual host cells to cause disease • Bacteria examples: • Anthrax (bacillus anthracis) • Cholera (Vibrio cholerae) • Plague (Yersinia pestis) • Rickettsia example: • Q-fever (coxiella burnetii )

  6. VIRUSES Simplest type of microorganisms Lack a system for their own metabolism Depend on living cells to multiply Won’t live long outside a “host” Examples: Smallpox Equine encephalitis Hemorrhagic fevers (Ebola, Marburg, Lassa).

  7. TOXINS • Toxic substances of NATURAL origin • Produced by a plant, animal, or microbe • Examples: • Botulism (botulinum) • SEB (staphyloccal enterotoxin B) • Ricin

  8. TOXINS Differ from “chemical” agents because... • They are not man made • More complex materials • By weight are usually more toxic than many chemical agents

  9. T-D-S

  10. THE NUCLEAR THREAT Threatened detonation of a nuclear weapon • Use of a threat as extortion • No known instance of any non-governmental group close to obtaining or producing a weapon Radiological Dispersal Device (RDD) • Use of a conventional explosive to disperse nuclear material to contaminate a large area • Example, truck bomb positioned near a nuclear power plant or an explosive device placed near nuclear cargo in transport

  11. NUCLEAR RADIATION TYPES Alpha Beta Gamma

  12. NUCLEAR RADIATION TYPESAlpha • Heaviest, most highly charged • Won’t penetrate the skin • Stopped by a sheet of paper • Internal hazard if radioactive particles are ingested by eating, drinking or breathing

  13. NUCLEAR RADIATION TYPESBeta • Smaller particle • Surface tissue penetration • Generally will not reach inner organs • May enter through unprotected open wounds, cause skin burns • Poses an internal hazard if ingested. • Disposal of contaminated clothing and thorough washing with soap and water as protective measure.

  14. NUCLEAR RADIATION TYPESGamma • Most penetrating • Produces acute symptoms • Skin burns • Nausea • Vomiting • Fever • Hair loss

  15. T-D-S

  16. An incendiary device is any mechanical, electrical or chemical device used intentionally to initiate combustion and start a fire. INCENDIARY INCIDENTS

  17. INCENDIARY DEVICES?

  18. CHEMICAL INCIDENTS • NERVE AGENTS: disrupt the central nervous system • BLISTER AGENTS (VESICANTS): cause severe burns • BLOOD AGENTS: interrupts Hemoglobin transport • CHOKING AGENTS: stress respiratory system • IRRITATING AGENTS: incapacitates by causing: • tearing, • respiratory distress, • pain.

  19. ROUTES OF EXPOSURE • INHALATION (primary) • ABSORPTION • DIRECT SKIN CONTACT: • nerve, • blister • irritant agents • INJECTION (least likely)

  20. NERVE AGENTS • Toxic even in small concentrations • Effects similar to organophosphate pesticides, but of a much higher toxicity

  21. Early outward warning signs and symptoms: NERVE AGENTS • Runny nose, nasal congestion • Profuse tearing, dimmed or blurred vision • Pinpoint pupils, eye pain aggravated by sunlight • Excessive salivation, abdominal pain, nausea • Involuntary urination and/or defecation • Chest pressure, cough, difficulty breathing • Excessive sweating • Muscle tremors, involuntary twitching • Giddiness, anxiety, difficulty in thinking or sleeping

  22. NERVE AGENTS • Resemble water or light oil in pure form • Odorless • Typically dispersed as aerosol • Important indicators and clues: • Small explosions • Presence of spray devices • Dead insects, birds, animals, people!

  23. Blister Agents • Readily penetrate clothing • Quickly absorbed • Very toxic, but less so than nerve agents • Effects similar to common corrosives • Examples: • Mustard Gas (H, HD) • Lewisite (L)

  24. Clinical symptoms may not appear for hours or days BLISTER AGENTS • Eyes (1 hr): Reddening, tearing, burning, “gritty” • Skin (1-12 hrs): Itching, redness, tenderness, burning pain, blisters,most intense in warm, moist areas of the groin and armpits • Respiratory (2-12 hrs): Burning sensation in nose/throat, hoarseness, profusely running nose, severe cough, shortness of breath • Digestive (2-3 hrs): Abdominal pain, nausea, bloody vomiting and diarrhea

  25. BLISTER AGENTS • Are heavy, oily liquids • Dispersed by aerosol or evaporation • Be alert for small explosions, fires or spray equipment • In a pure state are nearly colorless and odorless • Dark color and a garlic or onion odor • Outward signs: • Eye and respiratory irritation • Similar symptoms appearing in many individuals

  26. Result in asphyxiation by interfering with the ability of blood to transport oxygen BLOOD AGENTS • Toxic at high concentrations: rapid death • Common industrial compounds: • hydrogen cyanide (AC), cyanogen chloride (CK) • When under pressure are liquids • In pure form are gases • Victims require prompt removal to fresh air • And respiratory therapy in a hospital

  27. BLOOD AGENTS • Bitter almonds or peach blossoms • Clinical symptoms: • Respiratory distress • Vomiting /diarrhea • Vertigo / headaches

  28. Cause asphyxiation by respiratory edema(fluid in the lungs, resembling drowning) CHOKING AGENTS • Common industrial chemicals: • Examples: chlorine, phosgene • Clinical symptoms: • Severe eye irritation, coughing, choking • Phosgene has odor of newly cut hay

  29. Designed to incapacitate, “riot control” agents IRRITATING AGENTS • Generally non-lethal, but can result in asphyxiation • Confined spaces, high concentrations • Examples: • Chloropicrin, MACE (CN), • Tear gas (CS) • Capsicum (pepper spray) • Dibenzoxazepine (CR) • Clinical symptoms include: • Eyes and throat: burning, irritation, tearing • Respiratory: distress, coughing, choking, difficulty breathing • Digestive: nausea and vomiting, if in high concentrations

  30. T-D-S

  31. EXPLOSIVE INCIDENTS • Explosives used in 77% of U.S. incidents • Public safety agencies FIND only 20% • Residential properties common U.S. targets

  32. EXPLOSIVE INCIDENTS • 78% of terrorist bombs detonated or ignited • 22% failed to function as designed • 4% were preceded by a warning or threat

  33. BOMB THREATS • Telephone bomb threats are most common • All bomb threats should be considered “real.” • E-mail threats are more difficult to trace.

  34. EVACUATION CRITERIA • Pre-planned evacuation/assembly area • Have an alternate assembly point • Prior to use check evac area for suspect items • If any suspect item or vehicle is present, use alternate assembly point • Use terrain features or solid objects as shielding • If evacuating inside a structure go to farthest lateral point at least several floors below the device.

  35. EVACUATION CRITERIA • Avoid areas with flammable/hazmat, windows • Take a roll call and account for absentees • 300 ft. from small devices if you have shielding • 1000 ft. minimum from large devices in the open • Large device or vehicle bomb is suspected: >1000 ft.

  36. EXPLOSIVESDefinition Any substance, article or device designed to function by an extremely rapid release of gas and heat. For our purposes, if it goes “boom”, it’s a bomb.

  37. EXPLOSIVES/INCENDIARY Recap • IED’s and incendiary devices are designed and assembled to explode and cause fires • Explosions cause fires, and fires cause explosions! • Explosions release gas and heat • IED’s are designed to kill and terrorize • IED’s affect both structures and people • Bombings are the most likely terrorist attacks • Bombs usually work as designed • Always Evacuate after any explosion • The potential for secondary devices is real!

  38. T-D-S

  39. SCENE CONTROL • Public safety will coordinate incident response • Take control until “cavalry’s” arrival • Assist individuals in harm’s way to safety • Deny entry to unauthorized personnel • Establish perimeters and operational zones • Learn and initiate Incident Command System • Establish a safe refuge for the public • Begin media control

  40. If you witness suspicious activity or events: • Touch nothing • Evacuate the area immediately • Leave emergency response to the professionals • Be alert • Don’t become a victim!
