The foam is in a liquid form, that is clear with a light straw color, with a mild sweet odor and has a PH of 7-8.5. The AFFF or Aqueous Film Forming Foam is used for solid and regular fuels and also liquid fires like gasoline faster and without flashback. A carbon based fire has an equation of CH4+2O2->CO2+2H2O which then the foam puts out the fire by smothering it or basically taking away the oxygen from the equation.

In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire. If you want to put out a fire, just get rid of one of those three things – fuel, oxygen or heat. The charged squirt was then directed at the fire and the plunger pushed home to eject the water. Combustion is an intense chemical reaction. Fire extinguishing methods in ancient Egypt and Rome included use of hand water pumps and bucket brigades. Fire is a chemical reaction between oxygen and the fuel. It is completely soluble in water, not flammable, non explosive, and not an oxidizer. Flammable/Combustible Chemical Storage & Fire Protection Tips. While not everything is known about the combustion process, it is generally accepted that fire is a chemical reaction. 6.

The foam fire extinguishers use the foam to cover the whole fire and smother it, taking away the air so the fire can not keep on burning. Clean Agent: Interrupts the chemical reaction of the fire. Technology has advanced considerably to include other fire suppression techniques but still centers around removal of heat and/or oxygen from a fire and by interrupting the chemical reaction responsible for the fire. Because carbon dioxide is heavier than air, it displaces it. Fire is a very rapid chemical reaction between oxygen and a combustible material, which results in the release of heat, light, flames, and smoke. Then the chemicals are loaded into the tank, valve installed, and all other minor things including the hose are added on.
