What is a Carbon Dioxide Fire Extinguisher? Carbon dioxide fire extinguishers are filled with a non-flammable gas (carbon dioxide). These canisters contain extreme pressure, which enables the gas to spray out hard and fast. The pressure is so strong in these types of fire extinguishers that if you use one, you may see small bits of dry ice …
Carbon Dioxide fire extinguisher works by displacing oxygen from the fire triangle. The carbon dioxide is also very cold as it comes out of …
CO2 fire extinguishers – everything you need to know
CO2 fire extinguishers discharge CO2 gas, also known as carbon dioxide. This is stored in the extinguisher as a liquid, and the gas is created under pressure when the handle of the extinguisher is squeezed. This causes the CO2 gas to …
CO2s may be ineffective at extinguishing Class A fires because they may not be able to displace enough oxygen to successfully put the fire out. Class A materials may also smolder and re-ignite. CO2s will frequently be found in laboratories, mechanical rooms, kitchens, and flammable liquid storage areas.

How does a CO2 extinguisher work?
Instead, CO2 extinguisher work by replacing the oxygen surrounding the flames with carbon dioxide, meaning the fire can no longer burn. Pros: extremely effective on electrical fires; do not leave any residue behind when they are used.
What gas is in a carbon dioxide fire extinguisher?
Carbon dioxide fire extinguishers are filled with a non-flammable gas (carbon dioxide). These canisters contain extreme pressure, which enables the gas to spray out hard and fast. The pressure is so strong in these types of fire extinguishers that if you use one, you may see small bits of dry ice shooting out.
Do CO2 fire extinguishers work on chip pan fires?
This causes the CO2 gas to emerge at great speed, which is why CO2 fire extinguishers are not recommended for chip pan fires – they could literally blast the flames into surrounding areas. Unlike water and foam extinguishers, CO2 fire extinguishers do not work by cooling the fire and so are ineffective on fires…
