Info On Filters

• Filters come in many different shapes and sizes
  but they all use the same concepts and
  principles. Most gas masks are made mostly up of
  charcoal and a little other bit of filtering
  chemicals. These other filtering chemicals
  neutralize the bad chemicals or bacteria in the
  air. Some gas masks also have a piece of fine
  woven felt in it to catch the large nuclear,
  biological, and chemical (NBC) particles in the
  air.

P-M on Filters

• Positive now a day there is something else
  which is a lot safer. Its called chromium VI
  which is also known as a carcinogen which is
  harmless when solid but when damaged or over the
  age of 8 years old should be disposed of as if it
  was hazardous material.

• Minus until about 50 years ago there was
  something called asbestos which was in the mask.
  It causes bad respiratory problems and is not
  used any more. It is replaced with something else
  less harmful.

The Inventors 1/2

• Leonardo Da Vinci thought about making a mask
  made out of wet cloth, and in 1849 an man by the
  name of Lewis P. Haslett went off of Leonardos
  idea and made a lung-protector made out of wet
  wool.
• Other people in the 1600s tried to make a mask
  to protect from plagues and viruses. They used
  herbs and spices for it. John Stenhouses used
  charcoal as the filter and George Crofutts
  rubber eye and lung protector and William Moran
  made a mask out of asbestos for firemen.

The Inventors 2/2

• Garret A. Morgan he created the Morgan safety
  hood and smoke protector was patented in 1912
  and was mostly for fireman and engineering work
  where hazardous gases are present but was not
  meant in any way for war events.

The Gas Masks of 1917-1930

• 1917s-1930 during this period gas masks took a
  leap of faith and were used in the military. All
  the masks at that time were big, heavy and had
  very inefficient filtering. You had almost zero
  sight in this mask. The filters lasted less than
  an hour each.
• In this picture is a1919 mask which looks very
  tight. This mask used by the U.S. Navy.

Gas Masks of 1939-1948

• 1939-1948 gas masks were starting to show their
  advantages. Demand was rising and the quality of
  the masks decreasing. There were varieties of
  masks, but most failed. The masks were heavy and
  bulky by todays standards. They developed better
  glass, but it dirtied easily. The masks were
  poorly made and expensive.

Gas Masks of 1951-1968

• 1951-1968 these gas masks were similar to
  today's except they were not as comfortable, and
  the filter was dangerous. The lenses were clear
  and were rain proof. The masks were well made and
  were still very popular. The military was now
  putting filters on the side of the mask by your
  cheek and was attached directly. The masks
  design progressed and they could now drink from a
  concealed straw.

The Gas Masks of 1980-1990

• 1980-1990these masks were almost like ours today
  except for the technology and comfort. They had
  the same filter and lens as today. They were
  still a small burden but not as much as the
  1950s masks. As you can tell by the picture the
  mask design has progressed and is doing well.

10
The Gas Masks of 1991-2002

• 1991-2002these masks are the ones we use today
  in the field and are very little burden and are
  light. These masks are good looking and have
  Plexiglas lenses that are shatter proof and dont
  dirty easily. You can tell by the picture that
  this is the most advanced mask.

Other Gas Masks!

• Horse mask the US in WWI created the mask. It
  consisted of a muzzle piece connected to two
  filters.
• Armored car maskwas a light mask that had a
  small filter and the option to hook up to an
  oxygen tank.
• Air flight maskswere for dropping the NBC
  weapons and doing low scouting missions.

The Related Vocabulary Words

• Innovators- innovators are people who create new
  ideas and products just like Garret A. Morgan
  when he created the Morgan safety hood and smoke
  protector.
• Labor- labor is the act of people who are working
  in a factory or something that requires physical
  or mental work. The people that made the masks
  were working in a factory to do it.
• Great war- the great war was WWI and the gas
  masks were worn and made during WWI and therefore
  is related to the great war.

How Its Related to History

• Since WWI, the gas mask has been use to protect
  people from deadly nuclear, biological, and
  chemical warfare. It has saved the lives of
  many. They have allowed us to win anything from
  wars to fires, and have allowed us to do
  remarkable things over the years. The gas mask
  was used in WWI, WWII, Vietnam, Korea, desert
  storm and beyond.

What Do I Want to Teach You

• I want to teach that over the past centurys NBC
  has been made and has killed many and no matter
  how hard we try to protect ourselves we will
  always suffer in the aftermath. I propose that
  the US stop all countries that produce weapons of
  mass destruction and rid them of them. If they
  dont cooperate we should force them until they
  do. Nobody wants, or should have to die for
  something they have no say or part in. Gas masks
  are the way we protect ourselves, and if other
  countries want a fight,they should fight with
  wits and skill not mass killing.
