The document discusses chemical weapons used in World War I, including mustard gas and tear gas. Mustard gas caused large blisters on exposed skin and in the lungs, resulting in a painful death. Tear gas was non-lethal and caused temporary blindness, tears, and pain. While chemicals caused few direct deaths, they were effective at clearing out areas since there were no effective countermeasures at the time like gas masks. The document goes on to discuss phosgene gas and chlorine gas, which were both lethal, as well as early fragmentation bombs fired from artillery shells.

1. Types of Weapons & Gases
By: Gabriel Miller

2. World War I
• In World War I, chemical warfare became a
major component of the war.
• It developed more and more all the way
throughout the 20th century

3. Types of Gases
• Mustard Gas (also known as sulfur mustard):
this type of gas caused large blisters on
exposed skin and in the lungs, therefore
resulting in long painful death. In its pure
form, it is colorless and a viscous liquid. In its
impure form it is yellow-brown and has an
odor resembling mustard plants

4. Types of Gases
• Tear Gas: this is a non-lethal type of gas,
unlike mustard gas. It causes temporary
blindness, tears and extreme pain and affects
the corneal nerve (cornea is the transparent
part of the eye on the top).

5. Deaths/Usage
• Only 4 percent of the deaths in World War I
were from chemicals. At the time they were
very limited and not developed enough to
cause serious damage. However, it was very
effective when it came to clearing out areas.
There were no countermeasures to be used,
because gas masks hadn’t been invented yet.

6. Phosgene & Chlorine
• Both of these gases are lethal. They were both
used during the second world war.

7. Bombs
• In October 1914, German troops fired the first
fragmentation shells. A frag shell is a shell on
impact explodes into many pieces shooting
out pieces of metal (usually) to hit multiple
targets with a single shell.

8. Effects of Phosgene during War

9. Effects of tear gas (used nowadays
also)
