Fire extinguishers contain different chemicals, depending on the application. Handheld extinguishers, which are commonly sold at hardware stores for use in the kitchen or garage, are pressurized …
It is aqueous film forming foam and it needs a chemical reaction between water, fluoro tensides, and other various chemicals to create a fire fighting foams. 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. Background Research
