How to use a CO2 fire extinguisher and its proper mechanism of operation

A CO2 fire extinguisher is one of the most essential types of firefighting equipment used to combat electrical and flammable liquid fires. It works by displacing oxygen around the fire and cooling the fuel source, effectively stopping the combustion process without leaving any residue. Whether for offices, factories, or laboratories, understanding how CO2 extinguishers work is crucial for maintaining safety in any environment.

What Is a CO2 Fire Extinguisher Used For?

A CO2 fire extinguisher is primarily used for Class B and Class E (or electrical) fires. This includes fires involving flammable liquids like petrol, diesel, oil, and solvents, as well as electrical equipment such as computers, panels, and appliances. Because CO2 doesn’t leave residue or cause corrosion, it’s ideal for protecting sensitive electronic devices and machinery.

Unlike water or foam extinguishers, CO2 models don’t cause short circuits or equipment damage, making them a reliable choice for IT rooms, server areas, and commercial offices. You can find a wide range of certified firefighting tools at Alsafi for Safety Company, a trusted provider in Saudi Arabia known for quality and compliance with Civil Defense standards.

Is CO2 an ABC Fire Extinguisher?

No, a CO2 fire extinguisher is not an ABC extinguisher. ABC extinguishers are typically dry chemical types that can handle Class A (ordinary combustibles), Class B (flammable liquids), and Class C (electrical) fires. CO2 extinguishers, on the other hand, are designed for Class B and electrical fires only.

They are not effective on Class A fires (involving wood, paper, or cloth) because CO2 gas quickly disperses, allowing these materials to reignite once the gas has evaporated.

Is CO2 a Dry Chemical Fire Extinguisher?

No, CO2 is not a dry chemical fire extinguisher. Instead of using powder or foam, CO2 extinguishers contain compressed carbon dioxide gas stored under high pressure. When released, the gas expands rapidly, cooling and suffocating the fire by removing oxygen.

This clean agent leaves no residue, making it perfect for locations where cleanliness and equipment protection are priorities, such as hospitals, offices, and control rooms.

Pros and Cons of CO2 Extinguishers

Pros:

• No residue: Safe for electrical and electronic devices.
• Effective on flammable liquids and electrical fires.
• Clean agent: Doesn’t harm surfaces or equipment.
• Environmentally friendly: CO2 doesn’t deplete the ozone layer.

Cons:

• Limited range: CO2 discharges quickly and can’t cover large fires.
• No cooling effect: Fires may reignite once oxygen returns.
• Risk of suffocation: Should not be used in confined or poorly ventilated spaces.
• Requires regular maintenance: Pressure levels must be monitored for safety and effectiveness.

FAQ

Can CO2 extinguishers be used on electrical fires?
Yes, they are highly effective for electrical fires because CO2 is non-conductive and leaves no residue.

How often should CO2 fire extinguishers be serviced?
They should be checked annually and refilled or replaced every five years depending on pressure and condition.

What should I do after using a CO2 extinguisher?
After use, always have it recharged and inspected by a certified safety technician to ensure it’s ready for future use.

Can CO2 extinguishers be used outdoors?
They can, but wind can quickly disperse the gas, reducing effectiveness. They work best indoors in controlled environments.

How do I know if a CO2 extinguisher is still pressurized?
Check the weight or the pressure gauge. If it feels light or the indicator shows low pressure, it should be serviced immediately.
