Chemical Warfare Agents

1. CWA

2. Objective CWA . Effects of CWA’s on human body. First aid for different type of CWA.

3. Introduction Definition :- Chemicals that are used to cause the disturbance, disease, or death of humans during dissemination.

4. CW AGENT ? The chemical substance that used to produce physiological immobilization in war

5. ROUTES OF ENTRY OF CHEMICAL AGENTS

6. QUALITIES REQUIRED FOR A CW AGENT High toxicity Imperceptibility to senses (undetectable/insensible) Rapidity of action after dissemination Persistency

7. CLASSIFICATION/ TYPES OF AGENTS (A s per effects on body) NERVE AGENTS BLISTER AGENTS BLOOD AGENTS CHOKING AGENTS MENTAL INCAPACITATORS TEAR AGENTS

8. BLISTER AGENTS

9. BLISTERING AGENTS SULFUR MUSTARS NITROGEN MUSTARD LEWISITE

10. BLISTER AGENTS A blister agent is a chemical compound that irritates and cause injury to the skin. These substances also attack the eyes or any other tissue they contact. These agents are also known as the queen of CWA. EXAMPLES :- DISTILLED MUSTARD NITROGEN MUSTARD - HN 1 TO HN 3 LEWISITE -L

11. SYMPTOMS HEAVY EXPOSURE MAY LEAD TO CORNEA SHRINK AND BLINDNESS . BLISTER FORMATION ON SKIN

12. INGESTION OF BLISTER AGENT LEADS TO DESTRUCTION OF INNER LINING OF GASTRO INTESTINAL TRACT. NAUSEA VOMITING BLOODY DIARRHEA SHOCK

13. BLISTER AGENTS

14. BLISTER AGENT EXPOSURE

15. TREATMENT Immediate clean the effected area of the body by water. Clean the eye by water and petroleum jelly and cipro floxin eye drop . Provide iodine tablet can be used on the blister .

16. CHOKING AGENTS

17. CHOKING AGENTS ATTACK THE BREATHING PASSAGE AND LUNGS OF THE VICTIM. EXAMPLES :- PHOSGENE - CG . DIPHOSGENE- DP . CHLOROPICRIN- PS .

18. TOXIC SIGNS AND EFFCTS IMMEDIATE - SORE THROAT - COUGHING, TIGHTNESS OF CHEST - NAUSEA, VOMITTING AND HEADACHE - COUGH WITH WHITE AND YELLOW SPUTUM. - GASTRIC PAIN. - RAPID BREATHING & CARDIAC FAILURE.

19. TREATMENT DIURETICS & ANTIBIOTICS LASIXS BECLAMETHASONE (BECLATE INHALER ) REDUCE CONGESTION BY REDUCING SWELLING IN TISSUES

20. BLOOD AGENTS

21. HISTORICAL BACKGROUND DISCOVERED IN 1782 A.D. BY A SWEDISH SCIENTIST. EXAMPLES :- HYDROGEN CYANIDE ( HCN) . CYNOGEN CHLORIDE ( CNCL) .

22. SYMPTOMS ACUTE POISONING CHARACTERISED BY :- DIZZINESS HEAD ACHE PALPITATION (FASTER HEART BEAT) ANXIETY PARALYSIS AND COMA. DEAD WITH IN FEW MINUTS.

23. FIRST AID CRUSH TWO AMPOULES OF AMYL NITRATE AND HOLD CLOSE TO THE NOSE. REPEAT TREATMENT EVERY 4 TO 5 MINUTES UNTIL NORMAL BREATHING RETURNS OR UNTIL 8 AMPOULES ARE USED.

24. NERVE AGENTS

25. NERVE AGENTS SARIN (GB) SOMAN (GD) TABUN (GA) VX

26. NERVE AGENT:- G Agent: sarine , soman & Tabun V Agent : Vx Pose most significant threat. (Most Danger) All in liquid but vaporize readily at normal temperature V agent is more toxic then G agent Order of toxicity: Vx > soman > sarin > tabun Volatility : sarin> soman > Tabun > Vx

27. RECOGNISE THE SYMPTOMS EARLY SYMPTOMS RUNNING NOSE AND INCREASE OF SALIVA. TIGHTNES OF CHEST. DIMMED VISION. DIFFICULTY IN BREATHING.

28. RECOGNISE THE SYMPTOMS OF NA LATER SYMPTOMS HEADACHE DROOLING OF MOUTH DIZZINESS AND GEN WEAKNESS EXCESSIVE SWEATING.

29. FIRST AID COMBOPEN AUTO INJECTOR HAVING 2 MG ATROPINE SULPHATE AND 220 MG OXIME IS USED EVERY 15 MINUTES. MAXIMUM THREE INJECTIONS

30. IRRITATING AGENTS : CAUSE IRRITATION IN THE NOSE AND THROAT WHICH CAN LEAD TO VOMITTING. e.g.: DIPHENYL CHLORO ARSINE- DA , ADAMSITE - DM .

31. MENTAL INCAPACITATORS : CAUSE TEMPORARY MENTAL DISTURBANCES USUALLY PRECEDED OR ACCOMPANIED BY PHYSICAL EFFECTS. e.g. - BZ, MARIJUANA AND LSD .

32. RIOT CONTROL AGENTS ALSO REFERRED AS TEAR AGENTS. CAUSE IRRITATION ON THE EYES, FLOW OF TEARS AND STINGING SENSATION ON THE SKIN AND NOSE. Exp: CN, CS,CR .
