Co2 fire extinguisher
Fires are different according to their type, that's why fire extinguishers are divided into different categories and each of these categories is used to deal with specific fires. One of these types of capsules is the CO2 fire extinguisher, which is very suitable for fire incidents in classes B (flammable liquids and gases) and C (electricity and electrical energy) and has high efficiency. This capsule is filled with carbon dioxide gas, which is non-flammable. The internal pressure of the CO2 fire extinguisher is very high and its very low temperature makes it able to extinguish the fire by cooling the heat. This pressure is so high that when emptying the capsule, ice pieces along with carbon dioxide gas may come out of it. Similar to other standard fire extinguishers, the P.A.S.S method must be followed when using CO2 fire extinguishers. CO2 fire extinguishers are easily portable and prevent flames by displacing the oxygen needed for a fire. This type of capsule can also be used for class E fire incidents and it can be used for circuits such as generators, fuses, electrical panels and computers. Also, the CO2 capsule does not leave any residue after use and prevents cleaning problems. This capsule is also resistant to the risk of freezing and can be stored in cold environments. Although this capsule has advantages, there are also disadvantages, for example, CO2 fire extinguishers are not suitable for Class A fire incidents.
How to use a CO2 fire extinguisher
Being non-conductive, cheap price of co2 gas, not damaging electronic equipment, high speed of operation, no harm to nature, ease of recharging and the ability to extinguish a wide range of materials are among the advantages of this gas. This type of capsule does not damage the device when turning off the electrical equipment. 6 kg weight is usually used for electrical panels in residential houses.

In general, the price of this product varies according to volume and weight. To buy this capsule with good quality and good price (affordable), you can buy it from reputable companies such as Sepehr Immunizers. Despite such advantages, it is better to know that the toxicity of CO2 gas, which can cause suffocation in a closed environment, and CO2 gas is very cold and can cause burns. Despite all these things, the way to use the CO2 capsule is as follows.
Bring the fire extinguisher to the nearest fire place.
Remove the fuse.
Point the CO2 nozzle hose at the fire.
Press the valve.
Aim the CO2 gas directly at the fire.
Now that you know how to use CO2 fire extinguishers, know the safety tips when using CO2 fire extinguishers as follows.
Do not use CO2 fire extinguishers in closed spaces.
Do not use CO2 extinguishers near people or animals.
Do not use CO2 fire extinguishers to extinguish flammable liquids because the high pressure of CO2 when exiting will cause the liquid to spray and spread and spread the fire.
Types of CO2 fire extinguishers
CO2 fire extinguishers can be divided into several categories in terms of weight, which we will provide you with complete explanations below.
CO2 capsules are produced in sizes of 3, 4 and 6 kg in terms of weight, and these capsules are moved manually. These capsules are also produced in 12 and 30 kg sizes, which are moved by wheels. Of course, know that the weight declared for these capsules is not the actual weight of the capsule and the capsules are generally heavier. The stated weight is the weight of the extinguishing agent used in the capsules.
The price of co2 fire extinguishers

CO2 gas is considered as one of the most common fire extinguishing gases. Being non-conductive, cheap price of co2 gas, not harming electronic equipment, high speed of action, no harm to nature, ease of recharging and the ability to extinguish a wide range of materials are among the advantages of this gas.
Carbon dioxide gas is non-combustible, odorless, non-toxic and heavier than air, which has a density of 1/5 and is not a conductor of electricity. Its mechanism of action during a fire is in three ways: first, suffocating the fire by forming a heavy layer resistant to the passage of air, second, diluting the oxygen in the air around the fire area, and third, cooling the fire. Carbon dioxide increases in volume to 0.5 cubic meters of gas per kilogram of liquid during phase transformation. This ratio of liquid to gas is about 450 times, phase transformation from liquid to gas also absorbs a lot of heat. This gas is not effective when the fuel is able to produce oxygen to continue the fire.
Another characteristic of CO2 gas is that it does not cause damage to materials in the fire environment. Therefore, it is more suitable than water in cases where valuable materials have caught fire. CO2 is very suitable for electrical and electronic fires because it does not conduct electricity and does not cause damage to sensitive systems due to the absence of residual materials.
To extinguish the fire, the concentration of CO2 in the air should be proportional to the burning substance, but in general, for all fires, at least 34% should be provided. Therefore, at least 0.68 kg of liquid CO2 should be considered for each cubic meter of fire area. This ratio can be increased up to 1.5 kg for each cubic meter for the types of fire and its characteristics as well as the importance of flammable materials.
Because the body of this extinguisher must bear a lot of pressure, for this reason it is made of steel without seams. CO2 gas is heavier than air and non-flammable. For this reason, during extinguishing, it covers the surface of the fire well and replaces the oxygen, and as a result, the extinguishing process is carried out efficiently.
This extinguisher is mostly used in closed places and for extinguishing electrical installations and computer devices, because the said gas does not leave any traces in the place of consumption. These extinguishers are usually controllable. The head of the CO2 extinguishing pipe is in the shape of a funnel or trumpet, and the reason is this: 1- It prevents the high speed of the gas when leaving and allows it to expand. 2- Directs the fire extinguisher to the desired location.
Although carbon dioxide is not poisonous, it can be dangerous when it is used in large quantities in a closed space to extinguish a fire. If a cylinder containing carbon dioxide is used in a place without ventilation, it will reduce the amount of oxygen and anyone in that place will become unconscious. or even death due to lack of oxygen. In addition, the creation of fog caused by CO2 can reduce visibility and the error caused by this. If for any reason the pressure inside the cylinder increases, the safety valve that is set on the cylinder will operate and the excess pressure will be discharged. Therefore, this cylinder should not be placed under direct sunlight or in the vicinity of heating devices.
In order to work with the fire extinguisher, we first hold the carrying handle and remove the locking pin and press the discharge handle, and we must be careful that the body parts do not come into contact with the discharge pipe (during operation) because this part is very cold and It causes burns at the contact site.
In addition, this extinguishing agent is used in rescue groups to hunt vermin such as snakes, etc.
