10lb Co2 Fire Extinguisher

The 10lb CO2 Fire Extinguisher is designed to control fires involving flammable liquids and energized electrical equipment when the fire risks fall within its approved rating.
It uses carbon dioxide (CO2) as the extinguishing agent, releasing the gas through a discharge horn to help suppress flames. Unlike dry powder and foam extinguishers, CO2 does not leave solid extinguishing-agent residue, making it suitable for selected areas containing computers, electrical panels, control systems, and other sensitive equipment.
With a nominal CO2 charge of 10lb (approximately 4.54kg), this extinguisher provides a larger agent capacity than smaller portable CO2 models. During discharge, the pressurized carbon dioxide expands rapidly, helping reduce the oxygen available around the fire while producing a cooling effect.
The cylinder, operating valve, and discharge assembly must meet the applicable safety requirements. Before installation, check the fire rating, operating conditions, and local regulations to ensure the extinguisher is suitable for the intended location.

Key Features of the 10lb CO2 Fire Extinguisher

01.

CO2-Based Fire Suppression

Carbon dioxide helps suppress flames by reducing the oxygen available around the fire. It is commonly used for certain flammable-liquid and energized electrical equipment fire risks, subject to the extinguisher's approved rating.

02.

Residue-Free Discharge

CO2 disperses as a gas and does not leave powder or foam residue. This can be useful in areas containing sensitive electronic equipment, control panels, and electrical components.

03.

Aluminum Alloy Cylinder

The aluminum alloy cylinder stores the CO2 charge under pressure. Its construction must meet the applicable cylinder design and testing requirements. Regular inspection helps identify visible damage or other conditions that may require professional attention.

04.

Portable 10lb Capacity

The nominal 10lb charge is approximately 4.54kg of CO2. The actual filled weight and dimensions should be checked when selecting a mounting bracket, cabinet, or installation location.

Applications of the 10lb CO2 Fire Extinguisher

Electrical Equipment Areas

Suitable for selected electrical fire risks when the extinguisher's approved rating and local requirements permit its use.

Offices and Control Rooms

Can be considered for areas containing computers, control panels, and electronic equipment where avoiding powder residue is important.

Commercial and Industrial Facilities

May be installed near selected machinery and electrical equipment after a fire risk assessment confirms that CO2 is appropriate for the identified hazards.

10lb co2 fire extinguisher Components

CO2 Cylinder

The cylinder stores the carbon dioxide charge under pressure. It must be designed and tested for the specified charge and applicable working conditions.

Operating Valve

The valve controls the release of CO2 from the cylinder. It should be inspected for visible damage and maintained according to the manufacturer's instructions.

Discharge Horn

The discharge horn directs the expanding CO2 toward the fire. It must remain securely connected and free from visible damage or obstruction.

Safety Pin and Operating Handle

The safety pin helps prevent accidental operation during storage and handling. The operating handle activates the discharge mechanism when the extinguisher is used.

Product Label

The label provides essential information, including the nominal CO2 charge, fire rating, operating instructions, and applicable certification details. It should remain readable throughout the extinguisher's service life.

FAQ

What is the capacity of an extinguisher?

A fire extinguisher has a nominal carbon dioxide charge of approximately 4.54kg. Its total filled weight is higher because it includes the cylinder, valve, discharge assembly, and other components.

What types of fires can a CO2 fire extinguisher handle?

CO2 extinguishers are commonly used for certain flammable-liquid fires and energized electrical equipment fire risks. The permitted applications depend on the product's approved fire rating and the standards applicable in the installation market.

Does a CO2 fire extinguisher leave residue?

CO2 does not leave solid powder or foam residue after discharge. This makes it useful in selected areas containing sensitive equipment. However, the gas can displace oxygen, and the discharge horn can become extremely cold.

How long does a CO2 fire extinguisher discharge?

A typical market reference range is approximately 9–12 seconds. The actual discharge time depends on the extinguisher's design, operating conditions, and approved specifications.
