What is a CO2 Fire Extinguisher?
CO2 fire extinguisher works best in extinguishing Class B & C which are – flammable liquids & electrical equipment. It achieves this by occupying the place of oxygen, thus disrupting the fire triangle, and it also has a cooling effect in order to prevent re-firing.
Types of CO2 Fire Extinguishers
Here are the different types of CO2 fire extinguishers:
1. Portable Fire Extinguisher CO2
These fire extinguishers are purposefully small and designed to be easy to pick up and use. Their sum weight is not greater than 10 kg. They are available in the following specifications:
- 2 kg
- 3 kg
- 4.5 kg
- 5 kg
2. Trolley Type Fire Extinguisher CO2
These fire extinguishers are larger and come with a trolley for easy maneuverability. Their total weight is more than 10 kg. They are available in the following specifications:
- 10 kg
- 20 kg
- 25 kg
- 30 kg
Both types of CO2 fire extinguishers are effective for Class B and C fires, providing versatile options for different fire safety needs.
How CO2 Fire Extinguishers Work
CO2 fire extinguishers extinguish fires by displacing oxygen, breaking the fire triangle, and producing a cooling effect to cool the fuel, thus preventing re-ignition.
Details of CO2 Fire Extinguishers
The cylinder of a CO2 extinguisher is filled with highly pressurized carbon dioxide gas. It features a strong horn that helps reduce the high pressure of the gas, which may turn into tiny pieces of dry ice when discharged.
Pressure and Temperature
CO2 extinguishers contain carbon dioxide at a high pressure of 55 bars (825 psi). At this pressure, the gas is in liquid form. Upon discharge, the pressure is reduced, and the gas exits in its gaseous form, effectively extinguishing the fire. The temperature of the CO2 gas is -60°C, which is sufficient to cool the fuel and remove heat from the fire.
Co2 Fire Extinguisher Use
A CO2 fire extinguisher is used for Class B and C fires. Moreover, it is appropriate for electrical equipment.
Pros and Cons of CO2 Extinguishers:
Pros:
- Very efficient in dealing with electrical fires.
- May not leave behind any traces or residues when used
Cons:
- It is dangerous to hold the extinguisher by the horn as this can lead to cold burns.
- Not as eco friendly as other extinguisher types.
- They also displace oxygen in the surrounding area with CO2, which can lead to suffocation in case these are used indoors.
Applications of CO2 Fire Extinguishers
Here are the primary applications of C02 extinguishers:
Initial Fires in Various Settings
- Books and Archives: Protect valuable documents and archives without damaging them.
- Valuable Equipment: Safe for use on sensitive and high-value equipment.
- Precision Instruments: Ideal for protecting delicate and precise instruments.
- Electrical Equipment (below 600 volts): Safe for use in electrical fires without causing the conduction of electricity.
Suitable for Class B Fires
- Paraffin
- Diesel
- Crude Oil
- Methanol
- Ethanol
- Asphalt
- Paraffin
Suitable for Class C Fires
- Gas
- Natural Gas
- Methane
- Ethane
- Propane
- Hydrogen
Suitable for Class E Fires
- Electrically Burning Objects: Effective for fires where the primary source of ignition involves electrical equipment and installations.
These applications make CO2 fire extinguishers an important safety tool in environments such as laboratories, server rooms, oil refineries, and places where sensitive and valuable equipment is used or stored.
Identification of C02 Fire Extinguishers
CO2 fire extinguishers have a red cylinder with a black label for easy identification.
Co2 Cylinder Price in Pakistan
CO2 cylinder price in Pakistan varies depending on the size and brand, with options ranging from 1 kg to 50 kg, including brands like Naffco (UAE), Bavaria (Germany), and others from China. However, a Co2 Cylinder (3 kg) is available for Rs. 9,000 in Pakistan.
Wrapping Up
CO2 fire extinguisher can be used for Class B and C fires and it is suitable for electrical equipment.
They are ideal for computer laboratories, computer server rooms, telecommunications companies, petrol stations, and the oil business.
