There is no true 'gas' that is used to create the foam used to help extinguish any flammable liquids/metals that we run into. Most often you'll see AFFF (Aqueous Film Forming Foam) is the main foam that is used in most car fires or any flammable liquid fires. The foam is a concentrate, which can easily be compared to car wash soap. A small concentrate (usually from 3-6%) is used to create the foam blanket and eventually diminishing any air that the fire is using as fuel. All in all, it's not a gas, but more like car wash soap concentrate...that's the easiest way to compare it.
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.

What does afff mean?
AFFF stands for Aqueous Film-Forming Foam. It is a type of firefighting foam used to suppress fires by creating a film on the fuel surface, preventing the release of flammable vapors. AFFF is commonly used for combating fires involving flammable liquids, such as gasoline or jet fuel.
What is a afff fire extinguisher?
AFFF is Aqueous Film Forming Foam
Are you allowed to use the aqueous film forming foam on electrical fires?
No. I forbid it!
What gas is used to make foam for firefighting?
which gas helps to make the foam that firefighters use
What does atc stand for in firefighting foam?
Alcohol Type Concentrate
What is the suitable fire protection system to be used in a diesel engine generator room?
AFFF- Aqueous Film Forming Foam
What is aspirated foam?
Aspirated foam is a type of firefighting foam that is mixed with air to create a lighter, more expanded foam. It is commonly used in firefighting applications to suppress fires by smothering them and preventing oxygen from reaching the fuel source. The addition of air helps the foam to cover a larger surface area and adhere better to vertical surfaces.
What kind of fire extinguisher is required in diesel fire?
aqueous film forming foam (AFFF), if you have one, although CO2 or dry-chemical fire extinguishers are also rated for combustible liquids, such as diesel.
What two states of matter are required to form an aqueous foam?
To form an aqueous foam, you need a liquid (water) and a gas (air). The air gets trapped in the liquid to create bubbles, resulting in the foam.
An example of foam?
Shaving foam is an example of foam. It is a lightweight, frothy substance that is used to help lubricate the skin during shaving. Shaving foam is made up of tiny air bubbles dispersed in a liquid solution.
What propety of foam allows it to extinguish fire?
Most are water based, with a thickening power to make it heavier, the purpose of foam, in a firefighting use is to smother and deprive the fire of oxygen
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.
