How does a carbon dioxide extinguisher put out an electric fire?

Answer 1

Yes, carbon dioxide (CO2) can be used by a firefighter (or a trained individual on scene) to extinguish an electrical fire. The carbon dioxide fire extinguisher is a specific type of fire extinguisher, and is in fairly common use. Compressed CO2 is pumped into the cylinder, and held in there behind a hand-operated valve. Pull he pin, grab the handle with one hand and the handle of the nozzle with the other, and get busy. Use the PASS system: pull the pin, aim the nozzle at the base of the flames, squeeze the handle, sweep the nozzle from side to side. The CO2 extinguisher can be distinguished by the large "cone" of its nozzle. Be sure to grab the nozzle by the handle as it is insulated. The CO2 exits the bottle and is really cold when it does. It will freeze your hand if you grab the nozzle or the hose instead of the handle. The extinguisher will make a fairly loud noise when you discharge it, but expect that and then ignore it. You're the first responder, and you can effectively use this device, just like a firefighter would.

Answer 2

Water is a good conducter of electricity and hence, causes electric shocks when it is used to estinguish electrical fires. But carbondioxide, being a gas, it is a bad conducter of electricity and doesn't results in shocks when it is used to estinguish electrical fires. Therefore, we can conclude that carbondioxide fire estinguishers are good on electrical fires.

Answer 3

CO2 extinguishers deprive the fire of oxygen (and to a lesser extent heat).

Answer 4

In two ways, it displaces oxygen and it's vary cold.

Answer 5

oxygen is a fuel necessary for flames to exist. when CO2 replaces the oxygen then the flame is unable to be present.
