                                                                                                    Warfare and
                          the eyes, excessive watering from the eyes, reddening of face and neck,    Its Types
                          soreness of throat, increase in pulse and respiration are observed.
                     (c)  After 24 hours of exposure, there is a general increase in severity of above
                          effects. Inflammation of inner thighs, axilla, genitalia, tocks, followed by
                          onset of blister formation - blisters are large, filled with yellow fluid and
                          may be pendulous.
                                                                                                Note
                     (d)  After 48 hours, the blistering becomes more marked. Swelling of genitalia,
                          bronchitis, expectoration of mucous and dead cells with increased
                          temperature is observed.
               III. Blood Agents: Blood agents are mostly used as vapours and the usual entry
                     route is through the respiratory system. They produce their effects by interfering
                     with some of the vital body functions. In the liquid form the skin can absorb
                     them. Hydrocyanic Acid (AC) and Cyanogen Chloride (CK) are the important
                     agents in this group. Blood agents affect the respiratory system causing
                     inflammatory changes leading to pulmonary edema and stop of breath besides
                     local effects such as irritation of the eyes.

                     Symptoms of Blood Agents :Inhalation of AC or CK in sufficient quantity may
                     produce symptoms within seconds and death within minutes. Acute poisoning is
                     characterized by: -
                     (a)  Dizziness.

                     (b)  Headache.
                     (c)  Palpitation.

                     (d)  Anxiety.
                     (e)  Ataxia, paralysis and coma.

                     (f)  Cardiovascular collapse, respiratory arrest, convulsions and metabolic
                          acidosis are seen in severe cases.

               IV.   Choking Agents: These are chemical agents, which attack the lung tissues
                     causing pulmonary edema. The most common choking agent is Phosgene, which
                     is a non-persistent chemical agent. It is a colourless gas with a suffocating odour
                     reminiscent of moldy hay. Phosgene is rapidly hydrolysed in water leading to the
                     formation of hydrochloric acid, which is corrosive, affects lung tissues and
                     damages the capillaries. This is followed by seepage of fluid into the air sacs,
                     leading to pulmonary edema.

                     Symptoms of Choking Agents:
                     The symptoms are delayed and initially no symptoms are observed for two to
