Fire Extinguishers come in several different shapes, types, and sizes.
The most common extinguisher is an 'ABC' extinguisher, which contains a dry chemical powder which suppresses the fire, and disrupts the fire tetrahedron, which is necessary for any fire to exist (Fuel, Oxygen, Heat, Chemical Chain Reaction).
Class C(Electical fire) extinguishers often contain Carbon Dioxide(CO2), which is a gas. CO2 is used due it's non-conductive nature, and ability to remove oxygen from the fire tetrahedron.
Some fire systems employ the use of gases such as Halon, which is used in highly sensitive areas, such as computer server rooms, or areas where intricate equipment is used which would be damaged with the use of sprinkler systems or chemical fire suppressants.
N2, you know nitrogen gas
The gas becomes a liquid inside the extinguisher. When the extinguisher is operated, the liquid changes back to a gas when released.
There is equipment that connects from the gas tank to the fire extinguisher, and is deigned to keep from overpressurizing the extinguisher. Do NOT try this without the equipment.
Foam, dry powder or CO2 gas- a Class B extinguisher
Carbon dioxide
Carbon Dioxide
A self-contained fire extinguisher includes an extinguishing agent and usually a pressurized gas. In a CO2 extinguisher, the pressurized gas is also the agent.
Nitrogen can be used in fire extinguishers as gas propellant.
foam, NOT LIQUID
yes but it is depend on nature of gas whether it is flammable or not.... co2 is fire extinguisher gas widely used ....
The most common 'gas' in a fire extinguisher is carbon dioxide (CO2), but there are others. They include Halon 1211, Halon 1301, FM200, FE-36, Halotron I and a few more.
The gas extinguisher that is filled with carbon dioxide and one that is filled with foam can help put out a fire.
