CO2 Fire Extinguisher Full Specification a CO2 fire extinguisher is a vital safety tool used to combat fires caused by electrical equipment or flammable liquids. Unlike water or foam extinguishers, it uses carbon dioxide (CO2) to extinguish flames. This article provides an overview of CO2 fire extinguishers, their specifications, and key features. It also covers their importance and practical applications.

What is a CO2 Fire Extinguisher?

A CO2 fire extinguisher is a portable device that uses carbon dioxide gas to put out fires. It works by displacing oxygen around the fire, suffocating the flames. This makes it highly effective for electrical fires and sensitive equipment protection.

CO2 Fire Extinguisher Specifications

Here are the key specifications of CO2 fire extinguishers:

• Capacity: CO2 fire extinguishers come in 2 kg, 5 kg, and 10 kg sizes. The 2 kg is ideal for small offices, 5 kg for moderate risks, and 10 kg for larger spaces.
• Operating Pressure: The pressure inside a CO2 extinguisher is typically between 55 and 60 bar at 15°C. This pressure ensures CO2 stays in liquid form until it’s discharged.
• Discharge Time: A 2 kg CO2 fire extinguisher discharges in 8-12 seconds. A 5 kg extinguisher takes 12-15 seconds, while the 10 kg model lasts around 15-20 seconds.
• Discharge Range: The typical discharge range is 2-4 meters (6-12 feet), depending on the size of the extinguisher and internal pressure.
• Temperature Range: CO2 fire extinguishers can function in temperatures from -20°C to 60°C, making them suitable for both indoor and outdoor use.
• Material: These extinguishers feature steel cylinders for durability. The discharge nozzle and hose are made from corrosion-resistant materials for long-lasting performance.
• Fire Classes: CO2 fire extinguishers are effective against Class B and Class C fires. Class B involves flammable liquids, such as oil and solvents, while Class C covers electrical fires like those in circuit boards or computers.
• Maintenance: CO2 extinguishers need periodic inspection, typically every 1 to 2 years. This involves checking the pressure gauge, inspecting for leaks, and verifying that the nozzle is unobstructed.

Features of CO2 Fire Extinguishers

• Non-Conductive: CO2 is electrically non-conductive, making it perfect for electrical fires, such as those involving circuit boards, computers, or electrical panels.
• No Residue: CO2 leaves no residue behind, unlike foam or powder extinguishers. This makes CO2 ideal for protecting sensitive electronics and equipment, especially in server rooms or laboratories.
• Effective Cooling: CO2 absorbs heat and cools the surrounding area, which helps extinguish the fire quickly while minimizing further damage.
• Portable and Easy to Use: These extinguishers are lightweight and easy to operate. The nozzle can be aimed at the base of the fire, and the user can activate it with a simple squeeze.

Advantages of CO2 Fire Extinguishers

• Ideal for Electrical Fires: CO2 is the best choice for electrical fires, such as those involving computers, appliances, and electrical panels.
• No Damage to Equipment: Since CO2 leaves no residue, it won’t damage valuable equipment. This is especially important in data centers, laboratories, and offices.
• Environmentally Friendly: CO2 is a non-toxic and natural gas, making it more environmentally friendly than other chemical-based extinguishers.
• Long Shelf Life: CO2 extinguishers have a long shelf life and require minimal maintenance, aside from occasional pressure checks.

Applications of CO2 Fire Extinguishers

• Offices and Commercial Buildings: CO2 fire extinguishers are common in offices, especially around electrical equipment like computers, servers, and office machines.
• Industrial Settings: In industries with flammable liquids or gases, such as oil refineries and chemical plants, CO2 extinguishers are crucial for fire suppression.
• Laboratories and Research Facilities: CO2 extinguishers are ideal for labs, where fires may involve chemicals or delicate equipment. The lack of residue makes them a safe choice for these environments.
• Data Centers and IT Rooms: These extinguishers are widely used in data centers and server rooms because they won’t damage sensitive electronic equipment.

How to Use a CO2 Fire Extinguisher

1. Pull the Pin: First, remove the safety pin to unlock the lever and discharge mechanism.
2. Aim the Nozzle: Point the nozzle at the base of the fire, where the fuel source is located.
3. Squeeze the Lever: Apply steady pressure on the lever to release the CO2. Move the nozzle side to side to cover the fire.
4. Keep a Safe Distance: Stand at least 1-3 meters away from the fire to avoid the cold blast and ensure safety.

Conclusion

CO2 Fire Extinguisher Full Specification CO2 fire extinguishers are highly effective for extinguishing electrical and flammable liquid fires. Their ability to leave no residue and work in sensitive environments makes them an essential tool in offices, industrial settings, and homes. Understanding the specifications and features of a CO2 fire extinguisher will help you select the right model for your needs.
