Introduction:
Carbon dioxide extinguishers are filled with carbon dioxide gas, which can’t start a fire. The CO2 fire extinguisher can be easily identified by its hard horn and lack of pressure gauge. The pressure in the extinguisher is so extreme that bits of dry ice may shoot out of the horn when discharged. Just like a typical ABC fire extinguisher, it is important to fire the CO2 extinguisher using the P.A.S.S. Method. For interested buyers, we are a reliable co2 fire extinguisher supplier and fire blanket supplier around.
What is Fire Extinguisher:
A carbon dioxide (CO2) fire extinguisher is a portable, active fire protection device that works by shooting carbon dioxide onto a fire. It works by taking away the oxygen that the fire needs to keep going. It is most often used to put out fires that are caused by flammable liquids or gases.
Carbon dioxide fire extinguishers are a very common form of fire extinguisher and are used in situations where traditional water and foam fire extinguishers or dry chemical fire extinguishers are not suitable. A carbon dioxide fire extinguisher is a “clean extinguisher” and leaves no residue on the area it is applied. We are among the fire hose reel manufacturers in town.
Top 5 Things You Need to Know About Fire Extinguishers:
What are They Made Off:
CO2 fire extinguishers are made for liquid fires in Class B and are safe to use on live wires. Class B fires that can be extinguished with a carbon dioxide extinguisher include flammable liquids and gases, solvents, oil, greases (excluding cooking oils/greases), tars, oil-based paints, and lacquers. CO2 can also be used to put out Class C fires, which involve electrical equipment that is turned on.
How Does it Work:
CO2 pushes the oxygen away, which puts out the fire. When the fire extinguisher lets out CO2 gas, it looks like dry ice. This “cloud” of CO2 makes the air around the fire have less oxygen, which puts out the fire. Due to wind drift, this type of fire extinguisher doesn’t work well outside. Carbon dioxide can be removed from a fire by the wind, which can also bring oxygen back to the flames.
Range of Fire Extinguisher:
The range of discharge is not very big. Once the CO2 is let out of the extinguisher, it will spread like any other gas. Because of this, the CO2 stream can only flow horizontally between 3 and 10 feet. This range is about half of what an ABC extinguisher’s average range is.
How to Use It:
They don’t leave anything behind when the fire is out. Carbon dioxide cuts off the fire’s supply of oxygen and makes the fire cooler because it is cold. Once the CO2 gas puts out the fire, it will just disappear into the air without leaving anything behind. Most of the time, no residue means no damage. This is a big advantage for expensive electronic equipment compared to using a typical ABC extinguisher, which uses a powder that can be corrosive.
Precautions:
Don’t let CO2 come in contact with your skin. It can make your skin freeze! When the carbon dioxide comes out of the extinguisher, it freezes into dry ice. CO2 is very cold, which helps to cool down liquids or electronics that could catch fire if there is a fire. But because the carbon dioxide is so cold, you should keep your bare skin away from the CO2 discharge.
How to Put Out a Fire with a CO2 Extinguisher:
CO2 fire extinguishers are mostly for electrical fires, but they can also be used on Class B liquid fires. Depending on the type of fire, they are used in different ways. Do not use CO2 extinguishers in small rooms because CO2 gas is poisonous at just 4% concentration and can kill at just 8% concentration.
With an extinguisher, you should only put out small fires. If the fire is already out of control, don’t try to fight it. Instead, get everyone out of the building and warn them about the fire. Then, call the fire and rescue service. If you try to put out the fire, make sure to stay safe and follow the steps below.
If the horn isn’t frost-proof, don’t hold it while it’s being used. It gets very cold and can cause severe frost burns. To keep this from happening, only buy CO2 extinguishers with frost-free horns.
If you squeeze the lever, the extinguisher will start to spray. Please keep in mind that the CO2 extinguishers make a very loud noise when they discharge.
Putting Out the Fire:
Liquids that can catch fire: Point the horn at the fire’s base and move around the area. Be careful not to get the powerful jet of the CO2 extinguisher on the liquid that is on fire.
Electrical Equipment:
Turn off the power where it is safe to do so to keep the fire from starting up again, and then point the horn straight at the fire.
Please keep in mind that a CO2 extinguisher can only be used for a very short time.
When using a CO2 extinguisher, make sure the fire is completely out. It is easy for fires to start up again. After use, CO2 gas escapes, and if the fire is still very hot, it might just start up again.
