What is the effective range of a portable PKP extinguisher at 18 lbs?

• A. 21 ft
• B. 19 ft
• C. 23 ft
• D. 17 ft

Answer: (B)

The key idea is the distance at which you can reliably reach and knock down a fire with a PKP extinguisher. For an 18-pound PKP, the effective reach is about 18–20 feet. That means you want to be within roughly that range to hit the base of the flames with short, controlled bursts and to achieve a quick knockdown. Among the given options, the one that lies within that typical range is the best choice because it reflects the distance you should stay from the fire for effective use. Distances shorter than that may prevent you from reaching the base of the fire with adequate coverage, while distances much farther can reduce control and accuracy, making the extinguishing effort less reliable.
