What Is a 5kg CO2 Fire Extinguisher Used For?
A 5kg CO2 fire extinguisher uses pressurised carbon dioxide to suppress suitable fires without leaving powder, foam or water-based residue.
CO2 extinguishers are primarily used for: Electrical Fire Risks
CO2 is commonly selected for appropriate electrical fire risks involving equipment such as:
- Electrical switchboards
- Computers and servers
- Data and communications equipment
- Electrical machinery
- Control panels
- Office equipment
- Laboratory equipment
- Other sensitive electronic equipment
Because CO2 leaves no residue, it is particularly useful where powder or foam could contaminate equipment or cause additional cleanup.
Class B Flammable Liquid Fires
A 5kg CO2 extinguisher can also be used for suitable Class B flammable liquid fire risks, including certain fires involving petrol, oils, solvents and other flammable liquids.
Always select fire protection equipment according to the specific hazards present at your premises.
Why Choose a 5kg CO2 Fire Extinguisher?
A 5kg CO2 fire extinguisher provides greater extinguishing capacity than smaller CO2 models, making it suitable for larger areas and higher-risk applications with electrical equipment or suitable Class B hazards.
Common applications include:
- Server rooms
- Data centres
- Electrical rooms
- Electrical switchboards
- Offices
- Workshops
- Laboratories
- Commercial premises
- Manufacturing facilities
- Industrial environments
For smaller areas or lower-risk applications, a 2kg or 3.5kg CO2 extinguisher may be more appropriate.
Where Should a 5kg CO2 Extinguisher Be Used?
A 5kg CO2 fire extinguisher can suit locations with electrical equipment and suitable flammable liquid hazards.
Server Rooms & Data Centres:
CO2 provides residue-free protection for sensitive IT and electronic equipment.
Electrical Rooms & Switchboards:
Suitable for appropriate electrical fire risks where a clean extinguishing agent is required.
Offices:
Ideal for areas containing computers, printers and other electrical equipment.
Workshops:
Suitable where electrical equipment and appropriate Class B flammable liquid risks are present.
Commercial & Industrial Premises:
A practical option for larger areas with electrical equipment and suitable flammable liquid hazards.
CO2 vs ABE Fire Extinguishers
The correct extinguisher depends on the fire risks present.
A CO2 fire extinguisher is particularly suited to electrical equipment and suitable Class B flammable liquid hazards. It leaves no powder or foam residue.
An ABE dry chemical powder extinguisher provides broader coverage, including Class A fires involving ordinary combustible materials such as wood, paper, cardboard and textiles, as well as suitable for Class B and electrical fire risks.
If your premises contain a combination of general combustible materials and electrical equipment, an ABE extinguisher may provide broader overall fire protection.
What Fires Should a CO2 Fire Extinguisher NOT Be Used On?
CO2 extinguishers are not suitable for every type of fire.
They should not be used for Class A fires involving ordinary combustible materials such as:
- Wood
- Paper
- Cardboard
- Fabric
CO2 is also not suitable for Class F cooking oil and fat fires or fires involving flammable metals.
CO2 can be affected by wind and should not be relied upon for outdoor fires where the gas can rapidly disperse.
Always use an extinguisher only for the fire class for which it is rated and only when it is safe to do so.
Does CO2 Leave a Residue?
No. One of the major advantages of a carbon dioxide fire extinguisher is that CO2 does not leave behind powder, foam or water-based residue.
This makes CO2 particularly suitable for:
- Computers and servers
- Electrical equipment
- Switchboards
- Control panels
- Data equipment
- Laboratory equipment
- Sensitive electronics
Although CO2 leaves no chemical residue, discharged carbon dioxide can create an oxygen-deficient atmosphere. Appropriate safety procedures and ventilation are essential, particularly in enclosed areas.
5kg CO2 Fire Extinguisher Servicing & Maintenance
Fire extinguishers should be inspected and serviced in accordance with applicable Australian requirements and the conditions applying to the installation.
Commercial and workplace fire extinguishers require regular inspection and servicing to ensure they remain ready for use. CO2 cylinders also require periodic pressure testing in accordance with applicable requirements.
Always have fire extinguishers inspected and serviced by a suitably qualified fire protection professional. Call Fire Products Direct - 02 8313 5404
