Not every fire can be safely extinguished with water or powder. In facilities with electrical equipment or flammable liquids, CO₂ fire extinguishers provide a clean and effective solution.
What Is a CO₂ Fire Extinguisher?
CO₂ (carbon dioxide) extinguishers discharge a high-pressure stream of CO₂ gas. This gas:
- Removes oxygen from the fire, suffocating the flames.
- Cools the fire as the CO₂ rapidly expands.
Best Uses for CO₂ Extinguishers
CO₂ extinguishers are especially effective for:
- Electrical fires in offices, server rooms, and industrial settings.
- Flammable liquid fires (Class B).
Benefits of CO₂ Fire Extinguishers
- No residue – Leaves equipment clean, ideal for electronics.
- Non-conductive – Safe to use around live electrical equipment.
- Effective on liquids and electrical fires.
- Environmentally safe – CO₂ is a naturally occurring gas.
Limitations to Consider
- Not effective on Class A fires (paper, wood, fabric).
- Risk of cold burns or oxygen depletion in small spaces.
- Limited discharge range compared to other extinguishers.
Final Thoughts
For businesses with electrical systems or flammable liquid risks, CO₂ extinguishers are an essential part of a fire protection plan. When paired with ABC or specialized extinguishers, they provide well-rounded safety coverage.
