Co2 Portable Fire Extinguisher

A CO2 (Carbon Dioxide) Portable Fire Extinguisher is a type of fire extinguisher that uses carbon dioxide gas to put out fires. CO2 extinguishers are most commonly used for fires involving electrical equipment and flammable liquids. Here's a breakdown of its features and uses:

Key Features:
Fire Classes: CO2 extinguishers are particularly effective for:

Class B: Flammable liquids (e.g., gasoline, oil, paints).
Class C: Electrical fires (e.g., wiring, electrical panels, computers, and machinery).
Mechanism: CO2 works by displacing oxygen in the vicinity of the fire, suffocating the flames. The gas is released through a nozzle as a cold, dense cloud that quickly cools and extinguishes the fire.

Advantages:

No Residue: Unlike foam or powder extinguishers, CO2 leaves no residue, making it ideal for sensitive equipment such as computers, electrical panels, and delicate machinery.
Effective on Electrical Fires: CO2 is non-conductive, making it safe for use on electrical fires without the risk of further electrical hazards.
Disadvantages:

Limited Range: CO2 extinguishers typically have a shorter discharge range compared to powder or water-based extinguishers.
Cold Temperature: The gas is extremely cold when expelled, so care must be taken to avoid frostbite or injury from direct contact with the nozzle or discharge.
Common Use Areas:
Offices (especially for computer equipment)
Data centers
Electrical panels
Laboratories
Vehicles
CO2 extinguishers are available in various sizes, and their portability makes them suitable for both small and larger spaces. The 2kg or 5kg models are the most common for home or office use.
