CO₂ Fire Extinguishers
A CO2 fire extinguisher is an essential safety device for electrical fires and flammable liquid fires.
Carbon dioxide extinguishers work by displacing oxygen, smothering flames without leaving residue.
This makes a co2 fire extinguisher ideal for sensitive electronics, server rooms, and laboratories.
No cleanup means no damage to expensive equipment.
How it works: CO2 extinguishers discharge gas at extremely cold temperatures, rapidly cooling flames while eliminating oxygen.
Overview
Carbon dioxide fire extinguishers are engineered for Class B fires involving flammable liquids.
They’re also the safest choice for electrical fires where conductive agents pose serious risks.
The extinguisher contains pressurized liquid CO2.
Upon discharge, it converts to gas and creates a blanket effect that suffocates the fire.
- Class B liquids and electrical fires
- Server rooms and data centers
- Control panels and labs
- No residue; non-conductive
- Safe on live electrical equipment
- No cleanup required
- Use in ventilated areas
- Horn gets extremely cold
- Not for paper/wood fires
Why Choose CO2 Over Other Extinguishers?
When protecting valuable electronic equipment, CO2 extinguishers outperform traditional options.
Powder extinguishers leave corrosive residue that damages circuit boards permanently.
Water extinguishers conduct electricity and cause equipment failure.
Carbon dioxide extinguishers eliminate these concerns entirely.
Safe Use and Operation
Critical Safety Note: The discharge horn becomes dangerously cold. Always use the designated handle and never grip the horn directly to avoid frostbite.
- Pull pin, aim horn, squeeze, sweep
- Keep safe distance
- Use short bursts
- Ventilate area before re-entry
- Check for hidden embers
- Service/recharge immediately
Not for paper or wood fires – may re-ignite.
Ensure good ventilation after use.
Placement and Maintenance
Strategic placement ensures rapid access during emergencies.
Position units near electrical panels, server racks, and lab workstations.
Extinguishers should be mounted on walls at accessible heights.
Clear signage must indicate their location at all times.
- Mount near protected equipment
- Ensure clear access
- Install visible signage
- Monthly visual checks
- Annual professional service
- Recharge after any use
