CO2 Fire Extinguisher is one of the widely used fire extinguishers. A CO2 fire extinguisher can effectively tackle electrical and B class fires. Carbon Dioxide (CO2) fire extinguishers contain non-flammable and pure carbon dioxide gas as a fire extinguishing agent which is the most effective extinguisher media on live electrical equipment. The gas is filled at very high pressure. As per the view of the chemistry of fire, few gases are very effective in extinguishing the fire. Carbon dioxide is one of them. CO2 is very economical and is not harmful to human health. Carbon dioxide gas does not leave any residue behind and does not require cleaning services after the extinguishing process. CO2 gas extinguishes the fire by cutting off the supply of oxygen to the burning substance.
Carbon dioxide extinguishers are used for electrical fire risks and are usually the main fire extinguisher type provided in computer server rooms. They are used to extinguish Class B fire. CO2 extinguishers create a barrier to fire fires by displacing the oxygen the fire needs to burn. We can recognize the CO2 fire extinguisher by its black band around the cylinder.
CO2 fire extinguishers are most suitable for the places such as:

Total Weight : 17.0Kg
Hose Length with Horn : 75cm
Range of Discharge : 4-5m
Duration of Discharge : 13Sec
Paint Finish RAL : 3000
Knowing the different classifications of fire is important in understanding which type of fire extinguisher to use in an emergency situation.
Co2 fire extinguisher is ideal for class B and class E fire.
Class B fire includes flammable liquids like gasoline, acetone, kerosene, grease, paint, and alcohols. Flammable liquids catch on the fire and start burning easily at normal working temperature. Once the class B fire starts it is very difficult to control the fire and prevent its spreading. This class of fire involves nonmetal burning in a liquid state. This class of fire is a common hazard in industries that are dealing with lubricants and paints. We can extinguish this class of fire with a CO2 fire extinguisher.
Electrical Fire can originate from energized electrical equipment. It can start ignition in wires, cables, circuit breakers, and other electrical components. An electrical fire can start because of overloading on the circuits when the supply of electricity is inadequate. Electrical fires are often fueled by motors, appliances, and electronic transformers.
CO2 fire extinguishers can extinguish the fire effectively and economically. The fire extinguisher is a cylinder full of pressurized carbon dioxide in liquid form, as the CO2 gas is expelled it turns into a cloud of dry ice (snow). This cloud reduces the amount of oxygen in the air around the fire and smothers it. The CO2 gas is heavier than the oxygen so it effectively pushes it out, Cutting off the supply of oxygen to the flames. Carbon dioxide fire extinguisher works by displacing the oxygen from the flames. Due to its freezing temperature, it cools down the burning substance. Due to the absence of oxygen, the fire smothers and cannot reignite.
The CO2 is a clean and non-flammable gas and is considered as the best fire extinguishing agent. It can effectively tackle the fire caused by oil, petrol, solvents, etc. A CO2 fire extinguishers can also tackle electrical fires which is the most dangerous type of fire. It is best because it stops the influence of oxygen and decreases the oxygen present in that fire which leads to the fallout of fire.
Co2 gas we are commonly using in high-pressure cylinders. When fill it in under high pressure it becomes in liquid form. Mostly the internal pressure of the cylinder is between 1500 psi to 2000 psi. These portable fire extinguishers are commonly used in computer rooms, electrical manufacturing unit.
We can use a CO2 fire extinguisher in confined premises as well as open places. But in confined places, we have to make sure that no occupant is inside the premises. In huge electrical installations mostly it is used. Its installation is commonly done by using a fire suppression method in which large capacity cylinders are connected to the battery system. In this system, we interlink the cylinder in battery position.
The fire extinguisher usually expires after every 12 months. After a year the user has to refill the fire extinguisher because the expiry date of the extinguishing agent is 12 months or immediately after every use.
All kinds of fire extinguishers require refilling because the extinguishing chemical expires after a year. A fire extinguisher refilling is part of regular maintenance. As per rule a fire extinguisher requires refilling when the extinguishing agent expires. Refilling of fire extinguishing means refilling the fire extinguishers with the extinguishing agent. For some instances, refilling means emptying the cylinder and then refill it with the agent again. The extinguishing agent is refilled by weight to the appropriate amount for the size of the unit and as specified in the recharging instructions for that unit.
The refilling cost of the CO2 fire extinguisher depends upon the size of the fire extinguisher user wants to refill. The refilling of the fire extinguisher is more economical than purchasing the new extinguisher. The local service provider charges the amount for refilling according to weight and the original price of the fire extinguisher. Do you want to refile co2 fire extinguisher? Contact Us here
It is very useful fire fighting equipment because it offers many advantages such as:
It is a clean gas.
Leaves no residue behind.
Although it is the best type of fire extinguisher it also requires some cautions such as:
The extinguishers are very heavy and are difficult to move from one place to another.
Short discharge range.
We cannot use it in enclosed places.
