How long does a 27lb PKP extinguisher last and what is its range?

The chosen answer indicates that a 27lb PKP (Potassium Bicarbonate Powder) extinguisher has a range of 21 feet and lasts for 11 seconds when discharged. This information is based on the standard specifications for typical PKP extinguishers used in fire safety.

A 27lb PKP extinguisher is designed primarily for fighting Class B fires, which involve flammable liquids and gases. It has a powerful discharge that allows it to project the extinguishing agent over a substantial distance, which is essential for maintaining safety when combating fires from a safe distance.

The duration of 11 seconds is also significant, providing enough time to effectively extinguish a fire or to reach the affected area while applying the extinguishing agent. This time frame is adequate for targeting the base of the fire, which is key for fire suppression techniques.

While other choices present different ranges and durations, they do not align with the specifications for a 27lb PKP extinguisher. Understanding this detail helps in selecting the proper extinguisher type and ensuring effective usage in emergency situations.
