Fire is one of humankind's oldest discoveries; it's also one of our biggest threats. A fire can destroy in a matter of minutes a home or business that has taken decades to establish. That's why methods of putting out fires are so important. Many buildings are equipped with fire extinguishers
Putting out a fire caused, by a mortar attack, with a carbon dioxide (CO2) extinguisher. The white cloud coming from the horn is formed when liquid carbon dioxide stored under pressure in the extinguisher turns back to a gas

ring or pin on the handle stops the fire extinguisher from being set off by accident.
It also acts as a tamper-proof seal: if the ring is broken or missing, you know the extinguisher needs to be checked.
Inside the sturdy steel case, there's a canister containing high-pressure gas (orange with blue hashing).Most of the extinguisher is filled with water (blue).A tube runs right up the inside of the tube to a nozzle outside (gray).
The nozzle often ends in a piece of bendy plastic so you can easily direct it toward the base of a fire.To operate the extinguisher, you pull the ring and press the handle.Pressing the handle opens a valve (shown here as a green arrow) that releases the pressurized gas from the canister.
The gas immediately expands and fills the inside of the extinguisher, pushing the water downwardAs the water is pushed down, it rises up the tubeA jet of water emerges from the nozzle.
