CO2 Extinguisher

Definition

A CO2 extinguisher is a portable device, either wheeled or hand-held, used to extinguish small fires by ejecting carbon dioxide.

Purpose

The purpose of a CO2 extinguisher is to put out fires by displacing oxygen and cooling the fire, effectively suppressing it without leaving residue.

Examples of Use

• CO2 extinguishers are commonly found in laboratories and computer rooms where water-based extinguishers could damage equipment.
• They are used in kitchens to quickly extinguish grease fires.
• Industrial settings use CO2 extinguishers for electrical fires due to their non-conductive properties.

Related Terms

• Fire Extinguisher: A portable device used to combat small fires, available in various types depending on the fire class.
• Fire Class: Categories of fires, such as Class A (ordinary combustibles), Class B (flammable liquids), and Class C (electrical fires).
• Dry Chemical Extinguisher: Another type of fire extinguisher that uses a powder to smother fires.

Notes

CO2 extinguishers are effective for Class B and Class C fires but are not recommended for Class A fires involving combustible materials like wood and paper.
