How long does an 18 lb PKP extinguisher last during discharge?

An 18 lb PKP (Potassium Bicarbonate) extinguisher typically lasts about 14 seconds during discharge. This duration is based on the design and capacity of the extinguisher, which is engineered to effectively deliver a sufficient amount of its extinguishing agent to combat fires, particularly those involving flammable liquids and gases.

The 14-second discharge time allows for a concentrated and effective application of the agent, providing enough time for the user to target the base of the fire while also ensuring safety by maintaining an adequate distance. Understanding the discharge time is essential for effective fire fighting, as it helps users gauge how to approach the fire and manage their extinguisher's use efficiently.

Each type of extinguisher is designed with specific characteristics to suit different classes of fires, and knowing the discharge duration is critical for effective response in emergency situations.
