Handheld extinguishers, which are commonly sold at hardware stores for use in the kitchen or garage, are pressurized with nitrogen or carbon dioxide (CO 2) to propel a stream of fire-squelching …
Answer (1 of 4): Fire is the result of a chemical reaction called combustion. At a certain point in the combustion reaction, called the ignition point, flames are produced. Flames consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen. Moreover if …

The first role chemistry plays in a fire extinguisher is when you pull the lever to fire the foam onto a fire you release Carbon Dioxide which then replaces all of the foam within the bottle. This is an example of single replacement reaction. Then the foam is next where chemistry is used.
FIRE Fire is the visible effect of the process of combustion – a special type of chemical reaction. It occurs between oxygen in the air and some sort of fuel. The products from the chemical reaction are completely different from the starting material. The fuel must be heated to its ignition temperature for combustion to occur. The reaction will keep going as long as there is enough …
People Also Ask what chemical reaction occurs in a fire extinguisher
What is the chemical reaction that occurs in a fire?
Mainly: oxidation. Oxidation in a fire is the chemical reaction between the fuel and oxygen from the air. For most fuels this means the formation of water (from the hydrogen atoms in the fuel) and carbon dioxide (from the carbon atoms in the fuel).
What chemicals are in a fire extinguisher?
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 with nitrogen or carbon dioxide (CO2) to propel a stream of fire-squelching agent to the fire. The active material may be a powder such as potassium …
What is the chemical equation for fire extinguisher?
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. A fire extinguisher is made by forming a tank out of steel and then the pressure vessel inside by aluminum.
How are fire extinguishers made?
A fire extinguisher is made by forming a tank out of steel and then the pressure vessel inside by aluminum. Then the chemicals are loaded into the tank, valve installed, and all other minor things including the hose are added on. There are 7 different types of fire extinguishers ranging from foam to water to even dry powder.
