Explanation: The carbon dioxide is a gas which can prevent the spread of fire and extinguishes it. It is a gas which is used in an active fire extinguisher device which is used for extinguishing fire in the emergency cases. The carbon dioxide gas restricts the combustion of the fuel by the oxygen. It is filled in the fire extinguishing cylinders with force and compression …

Which gas is used as a fire suppression?
Only two gasses are used as fire suppression agents- carbon dioxide and Halon (bromotrifluoromethane). Halon, while effective at suffocating a fire by displacing air, is toxic and a powerful ozone depleting agent, so it is being phased out.
How do you prevent the spread of fire gases?
As a rule the spread of fire gases (and also smells from cooking and bad/old air etc.) is prevented by the pressure difference over the ventilation device (the hole in the wall).
How does a gas type extinguisher work?
A gas type extinguisher is filled with compressed CO2 gas which is released using a knob at the top (mostly). When the knob is unscrewed CO2 gas escapes the cylinder in the direction the nozzle is pointed.
Why is carbon dioxide effective at extinguishing a fire?
Carbon dioxide is effective at extinguishing a fire because it eliminates one side of the fire triangle. That is to say that it prevents oxygen from interacting with the fuel. Displacing the oxygen is much easier in an enclosed space such as a single room or vehicle compartment with limited availability of fresh air being replenished.
