Your basic CO2 fire extinguisher is filled with compressed CO2 gas, which is released as you trigger the extinguisher. The CO2 smothers the oxygen away from the flames to put out the fire. The cold form the CO2 decompressing also helps to remove some heat. There is also a foam based fire extinguisher. The foam is essentially produced by mixing a soaping agent with water. A stand alone extiguisher of this type usually has the soap and water preset and pressurized to come out of the extinguisher. The water will remove heat from the fire, and the foam will act to block the oxygen from the fire. These types of extinguishers are most effective against oil based fires. The last type of extinguisher is a type of dry chemical based extinguisher. These extinguishers will have the dry chemical in the cylinder and will often have a small canister of compressed CO2 on them. When the extinguisher is needed, the small canister is used to pressurize the dry chemical to force is out of the extinguisher. In all cases, extinguishers will run out after use. In general an extinguisher will provide one to two minutes of fire fighting ability. Extinguishers can be recharged, but only by someone trained to do so. For more information, you cna probably contact your local fire department. Most store bought extinguishers are not rechargable, but will need replaced use.<br><b>References : </b><br> There are several types of fire extinguishers.
