Chemical Weapons of Mass Destruction
4
Types of Chemical Agents
  • Vesicants / Blister Agent


  • Pulmonary (Choking) Agent


  • Incapacitating (Blood) Agent


  • Nerve Agent
5
Classification of Chemical Agents
  • Persistent
    • Substance can remain on material, equipment and terrain for long periods

  • Non-Persistent
    • Substance dissipates fairly quickly
6
Vesicants / Blister Agent
  • Agent Types:  Nitrogen / Sulfur Mustard, Lewisite, Phosgene Oxime
  • Mode of Action:  Acid-forming compounds that damages skin and respiratory system, resulting in burns and respiratory problems
  • Rate of Action:
    • Mustard - Vapors 4-6 hours, eyes and lungs affected more rapidly;  Skin: 2 to 48 hours.
    • Lewisite – Immediate
  • Physical Properties:
    • Mustard – Oily liquid, clear when pure, brownish when impure, odor of garlic or mustard

7
Vesicants / Blister Agent
  • Signs and Symptoms:
    • Severe skin, eye and mucosal pain irritation
    • Skin erythema with large fluid blisters, slow to heal and may become infected
    • Tearing, conjunctivitis, corneal damage
    • Mild respiratory distress to                            marked airway damage
8
Vesicants / Blister Agent
  • First Aid
    • Water in large amounts


    • 10:1 concentration of bleach







9
Pulmonary (Choking) Agent
  • Agent Types:  Chlorine, Hydrogen Chloride, Nitrogen Oxides, Phosgene
  • Mode of Action:  Compounds are acids or acid-forming, action is pronounced in respiratory system, flooding it and resulting in suffocation
  • Rate of Action:
    • Immediate to 3 hours
  • Physical Properties:
    • Chlorine – greenish/yellow gas, odor of bleach
    • Phosgene – colorless gas, odor of new mown hay

10
Pulmonary (Choking) Agent
  • Signs and Symptoms:
    • Airway irritation
    • Eye and skin irritation
    • Dyspnea, cough
    • Sore throat
    • Chest tightness
    • Wheezing
    • Bronchospasm
11
Pulmonary (Choking) Agent
  • First Aid
    • Vapor:  fresh air


    • Liquid:  copious water irrigation










12
Incapacitating (Blood) Agent
  • Agent Types:  Most Arsines, Cyanogen Chloride, Hydrogen Cyanide
  • Mode of Action:
    • Causes intravascular hemolysis that may lead to renal failure.  Cyanogen chloride/hydrogen cyanide
    • Cyanide directly prevents cells from utilizing oxygen.  The cells then use anaerobic respiration, creating excess lactic acid and metabolic acidosis.
  • Rate of Action:
    • Immediate onset
  • Physical Properties:  Colorless gas, odor of bitter almonds
13
Incapacitating (Blood) Agent
  • Signs and Symptoms:
    • Possible cherry – red skin
    • Possible cyanosis
    • Confusion
    • Nausea
    • Gasping for air
    • Seizures prior to death
    • Metabolic acidosis

14
Incapacitating (Blood) Agent
  • First Aid

Nerve Agents
16
 
17
Nerve Agents
  • Most toxic of the chemical WMD agents
  • Equivalent of pesticides for humans
  • Attacks the nervous system, affecting nerve impulses until the system can no longer control basic body functions
  • A single drop of the most potent types can cause convulsions, loss of consciousness, and death.



18
Types of Nerve Agents
  • Nerve Agents
    • VX
    • GA (tabun)
    • GB (sarin)
    • GD (soman)
    • GF (cyclosarin)


19
Nerve Agents:  Physical / Chemical Properties
  • Normally liquid; clear when pure, tan / brown when impure


  • Fruity or sulfur odor
20
 
21
Signs & Symptoms:  Low Dose
  • Low Dose / Minor Poisoning
    • Increased saliva
    • Running nose
    • Pressure on the chest
    • Pupil of the eye becomes contracted (night vision, short range vision, & pain)
    • Accompanied by headache
    • Unspecific symptoms:  tiredness, slurred speech, hallucinations and nausea
22
Signs & Symptoms:  Moderate
  • Higher Dose / Moderate Poisoning
    • Bronchoconstriction
    • Secretion of mucous in the respiratory system (difficulty in breathing and coughing)
    • Gastrointestinal tract (cramp and vomiting)
    • Involuntary discharge of urine and defecation
    • Powerful discharge of saliva, running eyes and sweating
    • Muscular twitching, weakness, local tremors or convulsions
23
Signs & Symptoms:  Severe
  • High / Severe Dose
    • Muscular symptoms are more pronounced
    • Convulsions and loss of consciousness
    • Poisoning process rapid
    • Earlier mentioned symptoms may never have time to develop
24
Mnemonic for Nerve Agent Exposure Symptoms
  • S – salivation
  • L – lacrimation
  • U – urination
  • D – defecation
  • G – gastrointestinal pain
  • E – emesis
  • M - miosis
  • D – diarrhea
  • U – urination
  • M – miosis
  • B – bronchorrehea, bronchoconstriction
  • E – emesis
  • L – lacrimation
  • S - salivation
25
Time-Line
  • Symptoms
    • Onset within seconds to minutes (hours)
    • Dependent upon dose
    • Dependent upon route of exposure
  • In general, “for vapor exposure” the longer the time from exposure to development of symptoms, the less severe the effects


26
Types & Treatments for Exposures
27
Types of Exposures
  • Vapor
    • Generally more severe with faster onset of symptoms
  • Liquid
    • Slower onset.  Penetrate clothing to be absorbed through skin.
    • (With vapor exposure also consider liquid exposure via skin contact).
28
Mechanism of Action
  • Absorption (any body surface)
    • Skin
    • Eyes
    • Respiratory Tract



29
Treatment of Mild Exposure
  •  Symptoms
    • Constricted pupils, headache, mild runny nose, salivation, localized sweating, nausea, vomiting, localized muscle twitching, feeling of weakness
    • Onset:
      • seconds to minutes for vapor
      • 30 min to hours for liquids
  •  Treatment
    • Observation only
  • If shortness of breath is increasing
    • 1 MARK I Kit
30
Treatment of Moderate Exposure
  •  Symptoms
    • Constricted pupils, runny nose, SOB, wheezing, secretions, muscle weakness, vomiting, diarrhea
    • onset within 10 minutes
    • Treatment
    • 1 to 2 MARK I Kits
31
Treatment of Severe Exposure
  •  Symptoms
    • Unconscious, seizures, flaccid paralysis, apnea
    • Onset of symptoms immediate (1-30 minutes)
