Is there a carbon dioxide firefighting truck?

Question

I was watching fire trucks and a helicopter headed to a wild fire and started thinking about a giant carbon dioxide fire extinguisher mounted on to a truck, much like one used to deliver propane, with a low to the ground nozzle. It comes out extremely cold and removes the oxygen at the same time. Also, unlike water out here in west Texas, carbon dioxide can be pulled out of the air.

Answer 1

There is no such thing as a CO2 fire truck. For one thing CO2 is a compressed gas and is primarily used for electrical fires. Second CO2 is expensive and would take a vast quantity to fill up a fire truck. Third, you would need to be relatively close to the fire in order for it work and that's not always possible. Fourth it would have no effect on outside fires due to the vast amount of oxygen. Anyway CO2 doesn't remove oxygen, it displaces it. It can't be just pulled out of the air, it's a compressd gas. You would need a semi sized truck to carry the equipment necessary to compresse the gas.

Answer 2

They have something like this for firefighting at airports.  It's a foam that comes out to smother the fires.  If you look at several fire extinguishers you will see that many are actually designed exactly the way you are thinking.  There are also Halon systems that choke fires the same way that are installed in commercial kitchens and other places vulnerable to grease fires.

Answer 3

yes they do, they also got a liquid carbon dioxide bomb (like a water bomb except its filled with liquid carbon dioxide) for helicopters

not all fire (such as chemical accident) can be put out by water so they have to have an alternative method of putting it out and this is when CO2 become handy
