Most firefighting foams use regular air. Before air is introduced, the liquid foam product is proportioned into water either ahead of time or as it flows through the fire house.
Air is mixed with the foam/water solution either at the nozzle or by using an air compressor (Compressed-Air Foam System(CAFS))
What else can I help you with?
What do the initials AFFF stand for?
AFFF stands for Aqueous Film-Forming Foam. It is used by fire fighters for the suppression of a fire where fuel is involved. It does this by coating the fuel and preventing oxygen enabling combustion.
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.
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.

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.
What gas is used by fire fighters?
Carbon dioxide. It will smother the fire.
Is a fire extinguisher the smae foam firefighters use?
No. Fire extinguishers use a dry powder to smother the fire. Firefighters use two types of foam that can be broken down into more categories. A class "A" foam is actually a type of soap. It is used to break up water tension so that water can seep into the ground and/or fuel better. A class "B" foam is used to make a blanket that smothers gasoline or diesel type 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 gas is used to make foam for firefighting?
which gas helps to make the foam that firefighters use
Where should expanding foam not be used?
Expanding foam should not be used in areas where it can come into contact with heat sources, as it is flammable and can pose a fire hazard.
Which gas helps make the foam that firefighter use?
well the tank that holds the foam is compressed with co2 but what actually makes the foam is the nozzle it acts as an aerator and thus making the liquid into foam ----------------------------------------- Air is the most simple example of gas used in foam fire extinguishers.
What type of foam is used to extinguish a polar solvent fire?
Alcohol-resistant foam is typically used to extinguish fires involving polar solvents, such as acetone or methanol. This type of foam forms a barrier between the fuel and the oxygen in the air, smothering the fire and preventing reignition.
