What is the maximum effective range of a 15-pound Co2 extinguisher from the outer end of the horn?

The maximum effective range of a 15-pound CO2 extinguisher is typically around 8 to 10 feet (2.4 to 3 meters) from the outer end of the horn. This distance allows for effective application of the CO2 gas to smother fires. However, optimal performance is achieved closer to the fire source, as the extinguisher's effectiveness decreases with distance. Always ensure to aim the horn at the base of the fire for the best results.
