CO2 Fire Extinguishers

Best for Class B & Electrical Fires

CO2
Fire Extinguishers

COâ‚‚ Fire Extinguishers, labeled with a black label, are highly effective for tackling electrical fires and flammable liquid fires (Class B). These extinguishers are commonly found in computer server rooms, offices, and industrial facilities due to their clean-agent properties.

Suitable for:

  • Class B: Flammable Liquids (Petrol, solvents, spirits)
  • Electrical Fire Risks
Firepower-CO2

COâ‚‚ extinguishers are unique because they contain pressurized carbon dioxide gas, rather than a liquid-based extinguishing medium. One key advantage is their ability to suppress fires without leaving any residue, making them ideal for protecting sensitive electrical equipment.

According to the latest BS5306 standards, it is required to install an extinguisher that can combat electrical fire risks, such as COâ‚‚, within 10 meters of any electrical equipment.

How COâ‚‚ Extinguishers Work

COâ‚‚ extinguishers function by displacing oxygen at the base of the fire, effectively smothering the flames and cooling the fire to prevent re-ignition. However, since COâ‚‚ does not remove heat or fuel, there is a risk of fire reignition once the gas disperses.

Safety & Handling Precautions

  • Frost-Free Horn: COâ‚‚ is expelled at extremely low temperatures. Never hold the horn while in use, as it can cause severe frost burns.
  • Thermal Shock Risk: Be cautious when using on delicate electronic components, as sudden cooling may cause thermal shock.
  • Short Discharge Time: COâ‚‚ extinguishers discharge quickly—usually within 10 seconds—so aim directly at the fire’s base.
  • Ventilation Matters: Ensure proper ventilation after use, as COâ‚‚ gas displaces oxygen and can pose an asphyxiation risk in confined spaces.

Recommended Use & Pairing

While COâ‚‚ extinguishers are excellent for electrical and flammable liquid fires, they should be paired with other extinguisher types for broader fire protection. For example:

  • Foam or Dry Powder Extinguishers for Class A fires (wood, paper, textiles)
  • Wet Chemical Extinguishers for kitchen and oil fires

Frequently Asked Questions

A CO₂ extinguisher works by displacing oxygen at the base of the fire, cutting off the fire’s oxygen supply and reducing heat to prevent reignition.

They are most effective for Class B fires (flammable liquids) and electrical fires.

Yes! Since they leave no residue, COâ‚‚ extinguishers are safe for electrical fires without damaging sensitive equipment.

  • No residue – Safe for electrical equipment.
  • Fast-acting – Quickly extinguishes flames by displacing oxygen.
  • Compact & effective – Ideal for offices, data centers, and industrial spaces.

COâ‚‚ extinguishers are not as effective outdoors, as wind can disperse the gas too quickly before it fully suppresses the fire.

Most COâ‚‚ extinguishers discharge in 5-10 seconds, depending on the size. Always refer to the manufacturer’s guidelines for specific details.

No, COâ‚‚ extinguishers are not recommended for Class F (cooking oil/fat) fires. Use a Wet Chemical Extinguisher instead.

  • Short discharge time – Typically 10 seconds or less.
  • No cooling effect – Fire may reignite once COâ‚‚ disperses.
  • Risk of suffocation – Should not be used in confined spaces without ventilation.

Follow the PASS acronym:

  1. Pull the pin to break the tamper seal.
  2. Aim the horn at the base of the fire.
  3. Squeeze the handle to release COâ‚‚.
  4. Sweep the extinguisher from side to side to cover the fire evenly.

Only if the area is properly ventilated. COâ‚‚ displaces oxygen, which can be dangerous in small, enclosed spaces. Adequate ventilation is essential when using them in enclosed areas.
