How long does an 18lb PKP extinguisher last and what is its range?

An 18-pound PKP (Potassium Bicarbonate) extinguisher is designed primarily for extinguishing Class B and Class C fires. The typical range of such an extinguisher is around 19 feet, which allows the user to maintain a safe distance from the fire while effectively applying the extinguishing agent. The duration of discharge is approximately 10 seconds, giving the operator enough time to aim and control the flow towards the base of the fire.

This combination of range and duration is critical for ensuring effective fire suppression while also minimizing risk to the user. Longer range and a decent discharge time allow for better targeting of flames and provide an opportunity to retreat in case the situation worsens. Additionally, the specifications align with the design standards for fire extinguishers, which are meant to offer both safety and efficacy in emergency situations.
