What is Fire fighting foam?
Fire fighting foam is used to smuther fires. The foam will work as a blanket on the fire to prevent oxygen and flames from re-igniting the area. Foam is best used on oil or gas spills but my fire department uses it for anything on fire to get the job done right and fast. Fire fighting foam is used to smuther fires.

How is aqueous film foam created for firefighting use?
Aqueous film foam (AFFF) is created by mixing water, fluorochemical surfactants, and stabilizers. The mixture is then aerated to produce a foam that can be used to suppress fires. When applied to a fire, the foam creates a blanket that separates the oxygen from the fuel source, effectively smothering the fire and preventing re-ignition.
Why do you use foam on a oil fire?
foam is used for fire suppression. what it does is it cools the fire and to coats the fuel, preventing its contact with oxygen, and then the fire is out.
Why is alkali foam used?
It is used as a fire-fighting agent in airports, oil refineries, etc where burning fuel and electrical wiring would rule out the use of water for fire fighting. that is my guess as to what you are talking about. water has to be combined with carbon dioxide- one process was the Cardox process once located in Hoboken- they made fire extinguishers of the foam pattern and also larger engines for applications at air fields and similar sites.

What is fire fighting equipment used for?
fighting fires
What type of fire extinguisher should be used on a potassium and sodium fire?
powder or foam :)
What should be used to put off petrol fire?
foam fire extinguisher or a fire retardant spray
What is the gas that helps to make the foam that firefighters use?
fire retardants used in the foam are trimethyltrimethylene glycol and hexylene glycol.
Which gas helps the foam that fire fighters use?
In a Compressed Air Foam System (CAFS), air or another gas is compressed and introduced into the foam solution. Larger systems use a dedicated air compressor and compresses regular air from the atmosphere.Smaller systems can use any inert compressed gas such as Carbon Dioxide (CO2), Compressed Nitrogen (N2) or smaller tanks of compressed regular air.The simplest, most efficient and least expensive way of producing foam is with a portable foam eductor. These foam systems use regular hand lines and an eductuor 100 feet from the end of the nozzle. The eductor siphons foam solution from a tank or drum using the "Venturi" principal. When the foam solution reaches a standard fog nozzle, water pressure and the broken stream produced by the nozzle introduce air into the foam solution.There are other forms of nozzles that introduce water using the "Venturi" effect that are not user adjustable like a fog nozzle.The quick easy answer is regular air is used most commonly in fire fighting foam however CO2 and N2 can be used depending on the design of the system used.In a Compressed Air Foam System (CAFS), air or another gas is compressed and introduced into the foam solution.

What is a fire suppressant used for?
A fire suppressant is used to remove one of 3 things from a fire. Depending on what the suppressant is, it operates by removing ONE of the 3. IE: CO2 works by removing the OXYGEN from the fire, water works by removing HEAT, and something like a fire fighting foam works by removing heat and the FUEL, by causing a blanketing action between flame and the fuel.
What type of foam is used to extinguish a polar solvent fire?
nonflameable kinds
