Carbon Dioxide (CO2) Fire Extinguishers

At Fullworks Fire Safety, we supply a reliable range of carbon dioxide fire extinguishers for sale online, suitable for commercial, industrial, and electrical environments across Australia.

A CO2 fire extinguisher is specifically designed for fires involving electrical equipment and flammable liquids. It is commonly used in server rooms, workshops, offices, plant rooms, and industrial settings where electrical fire risks are present.

Carbon dioxide extinguishers work by displacing oxygen and rapidly cooling the fire area. This smothers flames without leaving residue, making them the preferred fire extinguisher for protecting computers, electrical machinery, and sensitive electronic equipment.

Unlike dry chemical extinguishers, CO2 extinguishers are a non-conductive and non-corrosive gas solution, reducing the risk of damage to electrical appliances and electrical office equipment during a fire emergency.

Benefits of CO2 Fire Extinguishers

Residue-free extinguishing agent

Carbon dioxide gas leaves no powder, foam, or residue. This eliminates clean-up and reduces downtime in areas containing computer or electrical equipment.

Designed for electrical and flammable liquid fires

CO2 fire extinguishers are effective on Class B fires involving flammable liquids such as petrol and other fuels, as well as Class E electrical fires involving live electrical equipment.

Safe for electrical hazards

CO2 is a non-conductive gas, making it suitable for electrical hazard fires where water or dry chemical extinguishers may pose additional risks.

Available in multiple sizes

Our range includes 2kg and 5kg CO2 fire extinguishers to suit small offices through to larger industrial environments and electrical machinery areas.

Australian Standard compliant

All carbon dioxide fire extinguishers are pressure tested, clearly marked with a black colour band, and approved to AS1841.6 Australian Standards.

Frequently Asked Questions About CO2 Fire Extinguishers

What is a carbon dioxide fire extinguisher used for?

A carbon dioxide fire extinguisher is used for fires involving electrical equipment and flammable liquids. It is commonly installed near server rooms, electrical cabinets, machinery, and areas where electrical appliances or flammable liquids are present.

Is a CO2 fire extinguisher a dry chemical extinguisher?

No. A CO2 fire extinguisher is not a dry chemical extinguisher. It uses carbon dioxide gas as the extinguishing agent rather than powder. This means it leaves no residue and is ideal for electrical equipment where dry chemicals could cause damage.

Are CO2 fire extinguishers safe to use indoors?

CO2 extinguishers can be used indoors but should be operated with care. Carbon dioxide displaces oxygen and produces an extremely cold discharge that can cause frost burn if direct contact occurs. Avoid use in confined spaces where ventilation is poor.

Can CO2 fire extinguishers be used on Class A fires?

CO2 fire extinguishers are not recommended for Class A fires involving materials such as wood, paper, or textiles. They have a short discharge time and do not cool the fuel sufficiently, which can allow flames to reignite.
