2. What is Gas Warfare and how is it used? A chemical weapon used in World War Gas warfare was used in the trenches even when no attack was going on. Unlike machine guns gas warfare was silent but deadly Soldiers blinded by gas poison

3. Four Primary Types Of Gas Were Used In WWI 1. Lacrimators: effected-the eye and made it irritant and also called "tear gases” 2. Sternutators: effect- nasal irritants also called "sneeze gases” & "vomiting gases"),. “Sternutator gases were mixed with the other, more lethal, gases in order to interfere with the men wearing their protective gas masks. Often a soldier could be taken down up to 48 hours after the attack. It was later mixed with chlorine to cause the vapor to be spread more widely and more deadly. It was usually delivered in high explosive shells leaving the troops unable to immediately recognize its presence.” 3. Lung irritants: made people feel suffocanted & caused respiratory irritantions. 4. Vesicants caused skin irritantion and escharotics

4. History behind gas warfare Chemical warfare agents were used extensively in World War I (the United States had approximately 70,000 chemical casualties) By 1918 the use of gas warfare was widespread but effective measures used to protect the troops caused it to lose some of its popularity which lead for people to make masks and the element of surprise was gone.

5. Long Term Disabilities Gas Warfare caused a huge number of disabilities, leaving many people unable to work and suffer. Flash- Blindness and Blindness Mental Illness Skin diseases Cancer Sometimes it was a temporary effect if the person was lucky

6. What were some of the technological advancements ? used as a weapon for hiding soldiers in the war so that there were no enemies left. killed many defenders Poison gas was indiscriminate and could be used on the trenches even when no attack was going on

7. Protection It was also said that often time soldiers would soak clothes in their own urine and place it over the mouth to give protection against a chlorine attack. Soldiers also used make-shift gas masks if they were caught in the open without a gas mask during a gas attack By the end of the war gas masks were available to all soldiers and that’s when the use of gas warfare become very rare

8. How important was the usage of gas warfare? It allow to the do the unthinkable, which was that it allowed either the Allied or German to attack from the trenches without worry the soldier would be shot. It was a easy way to eliminate the enemies

9. Did any particular warfare change the course of the war? This widespread use of these agents of gas warfare, and wartime advances in the composition of high explosives, gave rise to an occasionally expressed view of World War I as "the chemists' war” Gas warfare can never be used again in fighting again, leading its use in WWI its last
