AFFF or aqueous fire fighting foam is a chemical agent that is added to water usually at a rate of about 300:1 (300gal water for 1gal foam concentrate) this mixture is then mixed with the outside air as it exits the nozzle and creates a blanket of foam that suffocates the fire.

What gas is used to make foam for firefighting?
which gas helps to make the foam that firefighters use
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 gas is used to make the foam for firefighters?
The same air that we breathe !!
What is the gas that is used in foam used by firefighters?

Which gas is in the foam used by firefighters?
Carbon Dioxide is the most common gas in fire extinguishers.
A gas that helps make foam?
Air is the simplest example.
What gas makes the foam firefighters use?
It's Carbon Dioxide (CO2)
What gas helps to make the foam that fire fighters use?
CO2
What gases are in firefighters foam?
The foam is not gas, but chemicals that prevent the fuel source in a fire from receiving the oxygen needed to sustain a fire.
Which is the gas that helps to make foam that firefighters use?
Air is the gas most commonly used to create the foam that firefighters use. Most commonly, the foam is generated by adding a small amount (1%-5%) of foaming agent into the water flow coming from the fire engine. This is done by either injecting it into the water stream with a small metering pump, or with a foam eductor which draws the foam into the water stream using a venturi. A foam play pipe, or Foam nozzle is used on the end of the water line which is designed to draw air into the stream of water, and creates the foam. More recently air compressors (CAFS - Compressed Air Foam System) are being added to some newer fire apparatus which injects air directly into the water stream. This allows for even less water to be used in firefighting, and produces a more consistant foam.
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.
Why does carbon dioxide helps to make foam that firefighters use?
it is a non-flammable gas that is effective at starving a fire of oxygen. Like other fire extinguishers (foam and water) it is only recommended for fighting certain types of fire. more infromation and recommendations on their use should be available through the fire department.
