25
Nerve Agents work how?
Interfere with normal transmission of the nerve impulses in the parasympathetic autonomic nervous system
26
What are the physical characteristics of a nerve agent?
Odorless, almost colorless liquids, varying in thickness and readily able to vaporize
27
Signs and Symptoms if exposed to nerve vapor
Pupils will constrict (pinpoint) muscular twitching Runny nose, difficult breathing, diarrhea, vomiting, convulsions, drowsiness, coma and unconsciousness
28
Treatment of Nerve Agent
Three 2mg auto-injectors of Atropine | Three 600mg auto-injectors of 2-PAM CI
29
For medical personnel what is the required therapy for Nerve agents?
Continue to administer atropine for 15 minute until mild atropinization occurs. This is noted by tachycardia and dry mouth.
30
Blister Agents work how?
Primary action on the skin, producing large and painful blisters that are incapacitating.
31
What are the common blister agents?
Mustard (HD), Nitrogen Mustard (HN), Lewisite (L)
32
How long does it take for blister agents to manifest and what does it effect?
Several hours. They attack the eyes and respiratory tract, as well as the skin.
33
Mustard (HN) and Nitrogen Mustard (HD) physical characteristics
Oily, colorless, or pale yellow liquids, soluble in water.
34
S/S of Exposure of Mustard
``` Gritting feeling in the eyes, spastic blinking of the eyelids photophobia. Burns in the sweaty areas (groin, armpits, face and neck). Irritation of the throat, hoarseness, a cough, difficult breathing, fever moist rales. ```
35
How long does it take for blistering to begin for Mustard?
12 hours but can delay to 48 hours
36
What is a frequent complication of Mustard?
Bronchopneumonia
37
What is the treatment for mustard poisoning?
No antidotal treatment. Remove as much of the Mustard as possible, asap.
38
Lewisite (L)
Arsenical (an arsenic-based compound) Light to dark brown liquid that vaporizes slowly.
39
S/S of Exposure to Lewisite
Lewisite causes intense pain upon contact. | Similar respiratory sxs of mustard
40
Treatment of Lewisite
EYES:Flushing eyes with copious amounts of water. Sodium Sulfacetamide, 30% solution, may be used to combat eye infection within 24 hours. SYSTEMIC: British Anti-Lewisite (BAL), Dimercapol
41
BAL is somewhat toxic, so how much can you inject before a person has severe symptoms?
3mg/kg
42
Blood agents work how?
Interfere with enzyme in the body, i.e. block oxygen transfer.
43
What are common blood agents?
Hydrocyanic acid (AC) and Cyanogen chloride (CK)
44
S/S of Exposure to Blood Agents
Either death or recovery. Violent convulsions after 20 to 30 seconds and respiratory failure with cessation of heart action within a few minutes.
45
Treatment of Blood Agents?
Amyl Nitrate in Crushed ampules (first aid) and IV Sodium thiosulfate solution.
46
What type of odor is Blood agents?
Almonds
47
After atmosphere has been cleared of Blood agents how many amyl nitrate ampules can be used on a patient who has been exposed to a Blood agent?
No more then eight.
48
What is required after the initial lifesaving measures for blood agents?
Sodium Thiosulfate
49
What is the required dose of Sodium Thiosulfate?
100 to 200 mg/kg given over a 9-minute period.
50
What is the key to success to cyanide therapy?
Speed
51
Choking Agents work how?
They cause extensive damage to alveolar tissue, resulting in pulmonary edema.

S/S of Exposure to Choking Agents
Watering of the Eyes, Coughing, and a feeling tightness in the chest. There will be no symptoms for 2 to 6 hours after exposure. LATENT SYMPTOMS: Rapid, Shallow, Labored breathing. Painful cough, Cyanosis, Frothy sputum, Clammy skin, Rapid, Feeble pulse, and low pressure. Shock may develop, followed by death.
55
Treatment of Choking Agents
Bed rest is mandatory. Keep victims moderately warm and treat resulting anoxia with oxygen.
56
Incapacitating Agents work how?
Produce mental confusion and an inability to function intelligently.
57
Characteristics of the Incapacitants
High Potency Effects produced mainly by altering or disrupting the higher regulatory activity of the CNS Duration of action comprising hours or days, rather than momentary or transient action.
58
S/S of Exposure to Incapacitating Agents
``` First symptoms can appear in 30 minutes to several hours and may persist for days. irrational statements delusions or hallucinations. dizziness, muscular incoordination, dry mouth, difficult swallowing. ```
59

60
Riot control/harassing agents work how?
Harass enemy personnel or to discourage riot actions
61
What are the two classes of riot-control/harassment agents?
Lacrimators and Vomiting Agents
62
Lacrimators work how?
Local irritants that act primarily on the eyes. High Concentrations- Irritate respiratory tract and the skin.
63
Chloracetophenone (CN) and Orthochlorobenzilidine Malanonitile (CS)
CN- Training Agent (Tear Gas) | CS- Riot Control Agent
64
S/S of Exposure to Lacrimators
Intense pain in the eyes with excessive tearing.
65
Treatment of Lacrimators
Fresh Air. Change Clothes. Wash yourself.
66
What are the different vomiting agents
Diphenylaminochloroarsine (Adamsite(DM)), Diphenylchloroarsine (DA) and Diphenylcyanoarsine (DC)
67
S/S of Exposure to Vomiting
``` Strong pepper-like irritation in the upper respiratory tract, irritation of the eyes lacrimation. sneezing, coughing, nausea, vomiting general feeling of malaise. burning sensation in the nose and throat, hypersalivation, rhinorrhea, frontal headache. ```
68
