What is the capacity of a CO2 extinguisher?

The capacity of a CO2 extinguisher is typically recognized to be around 15 pounds. This size is commonly used for a variety of fire situations, especially in environments where flammable liquids or electrical fires may occur. CO2 extinguishers are effective because they displace oxygen, effectively suffocating the fire, and they leave no residue, making them suitable for use on sensitive equipment.

While other capacities like 10, 20, and 25 pounds do exist, the 15-pound capacity is considered a standard size for commercial use, providing a good balance between portability and firefighting effectiveness. It's important to know this standard capacity as it helps in selecting the right type of extinguisher for specific fire risks in various environments.
