What is the approximate effective range of a CO2 fire extinguisher?

The effective range of a CO2 fire extinguisher is typically around 30 feet. This range allows a user to safely operate the extinguisher while maintaining a suitable distance from the fire to minimize risk. CO2 extinguishers work by displacing oxygen, thus suffocating the fire, and their ability to be effective from this distance provides a greater safety margin for the operator.

Choice details highlight that CO2 extinguishers are designed for class B and class C fires, which involve flammable liquids and electrical equipment, respectively. Having an effective range of approximately 30 feet allows for effective discharging without putting the operator in immediate danger, making it a critical aspect of their design and function.
