What is the maximum effective range of a 15lb CO2 extinguisher?

The maximum effective range of a 15-pound CO2 extinguisher is indeed around 4 to 6 feet. This range allows the operator to safely direct the CO2 onto the fire while maintaining a safe distance from the flames. CO2 extinguishers work by displacing oxygen, thus suffocating the fire. A range of 4 to 6 feet is practical because it enables effective usage without putting the user at unnecessary risk.

Using the CO2 extinguisher within this range ensures that the concentrated stream of carbon dioxide can reach the base of the fire where it is most effective. It is important for users to be aware of this range to effectively control different types of fires and to avoid being too close, which could lead to heat exposure and potential burns.
