Fire Extinguishers provide a fast and easy way of dealing with
a small fire in emergencies.

Fire Extinguishers in History
Kornel Szilvay
Fire extinguishers are used about 600 times a day in non-residential structures all over
the U.S and in the world.
They are used in Academic settings, Hotels/Motels, and the Environment
● Fire extinguishers are used 15,000 times each year in schools, colleges, and
● About 3,900 fires occur each year in hotels and motels. These damages result in
$76 million in property loss
● They are important in protecting the environment by controlling fires at very early
Fire Extinguishers provide many benefits in avoiding issues that can result from fires.
● A fire extinguisher works like a spray can.
● Excludes oxygen so that combustion can no longer continue.
● Has to extinguish the whole fire as soon as possible, so it
produces a powerful spray of water/foam/powder to do so.
Some might produce carbon dioxide, a heavy gas that
prevents burning.
● The extinguishing substance, like water for example, is put
under high pressure inside the extinguisher, and the pressure
forces the substance (or the water) out of the nozzle.
How it Works:
The Handle, or Discharge Lever,
is pressed.
The Valve in the Extinguisher
opens. The release valve admits
the gas inside the bottle to the
space above the water.
The Gas Escapes. The gas then
pushes down on the water, which
is driven up the Siphon Tube to a
hose connected to the nozzle.
The water (or foam) comes out of
the Nozzle and extinguishes the
