They can use one of three gases. In a foam extinguisher, it's usually compressed air which is very cheap--the price is just the electricity required to make it--and works well. They can also use carbon dioxide or nitrogen.

More often, however, they are made of metal or other strong materials (e.g., graphite-epoxy cylinders) that are designed to contain chemicals under pressure, whether those chemicals are water, CO2, dry powder or any other extinguishing agents.
The first recorded fire extinguisher was patented by Ambrose Godfrey in 1773 in England.
The first fire extinguisher was made in 1723 by Ambrose Godfrey.
"foam" fire extinguishers are made for hydrocarbon fires...i.e: gasoline, diesel, etc. These fires are considered class "b" (flammable liquids), and are mostly used by professionals and in commercial and industrial settings. These extinguishers are charged with anther AFFF, FFFP, or AR-AFFF, however, these class of extinguishers are only rated class A & B fires and are hazardous to the environment, humans and animals in addition to being very corrosive.
Aero Foam was created by Dr.Julius, a African American scientist. It is made out of soybeans, and has saved thousands of soldier's lives. It's a fire extinguisher tool, used by the navy. If you want to find out more about the scientist or Aero Foam, visit the Related Link.
Never ever use water on a gasoline fire or the fire will just spread. Smother it with sand, dirt, or a fire extinguisher specifically made for a gasoline fire.
Yes, Fire Extinguisher body made of mild steel iron
Thomas J Martin had an 1872 patent for a "Fire Extinguisher." He didn't invent the portable fire extinguisher; it had been around for over 100 years before he made his contribution to fire sprinklers. His motivation is not known.
The first carbon dioxide portable fire extinguisher in the USA was made by Walter Kidde & Co., Inc. in 1924.
A special fire extinguisher made for gasoline fires.
all i know is that the fire extinguisher was made by French C. Hopffer. It was patent in 1722 or 1724. This is all the info i know. I hope it helps!
It smothers AND cools because the extinguishing agent is made up of foam and water. The main reason for the foam is to keep vapors from rising from the flammable liquid and the water is naturally cool.
Because that is what the Dry powder (or Dry Chem.) is made for.
