CO2 Fire Extinguishers

Carbon dioxide (CO₂) fire extinguishers are essential fire safety equipment, purpose‑built to tackle Class B fires (flammable liquids) and safe for use on live electrical equipment. These extinguishers use CO₂, an inert, non‑conductive gas that suppresses combustion by displacing oxygen in the flame zone and delivering an intensely cold discharge to help cool heated surfaces.

Advantages of CO₂ extinguishers:

• Highly effective on energised electrical equipment: Thanks to its non‑conductive nature, CO₂ is ideal for protecting electrical equipment, servers, computers and other devices sensitive to dust or liquids. Unlike other agents, CO₂ does not impair the operation of such equipment.
• Leaves no residue: Carbon dioxide dissipates quickly after use, leaving no traces or residues. This is critical in environments where cleanliness and equipment protection are priorities, such as laboratories, data centres, server rooms and spaces with delicate electronics.
• Rapid cooling effect: The CO₂ discharge is extremely cold, which helps cool affected surfaces and reduces the likelihood of re‑ignition.
• Enhanced safety in industrial and commercial environments: Widely used where flammable liquids (oils, fuels, solvents) are present, CO₂ extinguishers provide effective protection without damaging assets.

Typical applications:

• Offices and commercial spaces: In workplaces with live electrical equipment (computers, servers, office devices), CO₂ extinguishers are commonly required to ensure appropriate fire protection.
• Laboratories and data centres: Recommended where flammable substances and electronic equipment coexist, including research labs, server rooms and IT equipment stores.
• Industrial facilities: Indispensable where risks stem from flammable liquids and electrical installations, enabling rapid, effective intervention.

How does a CO₂ extinguisher work?

CO₂ extinguishers discharge carbon dioxide gas at high pressure. On activation, the CO₂ forms a dense cloud that displaces oxygen around the fire, interrupting combustion. The gas is also very cold at discharge, which assists in cooling combustible materials and reducing the chance of re‑ignition.

Usage recommendations:

• Do not use on Class A fires: CO₂ extinguishers are not recommended for Class A fires (solid materials such as wood, paper, textiles) because they do not cool deep‑seated embers effectively.
• Use with proper training: Ensure designated users are suitably trained. Regularly check the extinguisher’s condition and pressure to confirm it is ready for use at all times.

Compliance with safety standards:

All extinguishers in this category comply with relevant national and international fire safety standards and are certified and approved for use in industrial and commercial environments (EN 3 series and applicable regulations), giving you confidence in the highest level of fire protection.
