The property used is its heaviness than air. CO2 being heavier than air, settles over the flames and cuts off contact with O2. Fire cannot continue without the oxygen supply and is extinguished.
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 bicarbonate (KHCO3), liquid water, an evaporating fluorocarbon or the propelling agent itself. The most effective and common fluorocarbon used until recently for this application had been bromochlorodifluoromethane (CF2ClBr), referred to as halon 1211. By international agreement, however, production of all types of halons ceased in 1994 because the bromine and chlorine atoms in the chemical were found to migrate over time to the stratosphere, where they react to deplete ozone in a very efficient catalytic cycle.

CO2 needs space, much space, as it expands from the extinguisher, so it removes the air around the fire. Without oxygen- there's no fire.
Carbon dioxide fire extinguishers can be used on Class B, C and E.
Fire extinguishers!!
Carbon dioxide.
Yes, a carbon-dioxide type of fire extinguisher contains ONLY carbon dioxide. Other extinguishers might use compressed nitrogen or other inert gases as propellants, as well as compressed carbon dioxide.
Carbon dioxide fire extinguishers are generally used because they absorb the oxygen content present in the air and thus help in extinguishing fire.
we can control the fire by the release of carbon dioxide which can be done by a fire extinguishers
The contents of some fire extinguishers are indeed a gass (Carbon Dioxide)
In fire extinguishers, they put carbon dioxide in it because it extinguishes fires. The two ingredients of carbon dioxide are; baking soda and vinegar.
Carbon Dioxide can be used to add fizz to drinksand is used in fire extinguishers because it dose not support cummbustion.
Carbon Dioxide based extinguishers are classified by the letters BC and ABC. They are primarily used in laboratories and should not be used in homes or businesses.
Carbon Dioxide is the most common gas in fire extinguishers.
