Purple K Class Wheeled Fire Extinguishers. Purple K Wheeled fire extinguishers are designed for industrial settings such as auto shops that have multiple cars in the same garage, airplane hangars, airplane repair shops, or airports where larger fires may occur to be able to cover a larger area.
Our solution is Purple K, a fast, efficient, environmentally friendly fire suppression agent. It is a potassium bicarbonate based dry chemical agent that extinguishes by changing flame chemistry and cooling. Purple K suppresses Class B (petroleum, oil, lubricant) and Class C (electrical) fires by interrupting a fire’s chemical reaction and cooling the flame/hot surfaces (endothermic …
Purple-K – Wikipedia
Purple-K, also known as PKP, is a dry-chemical fire suppression agent used in some dry chemical fire extinguishers. It is the second most effective dry chemical in fighting class B (flammable liquid) fires after Monnex (potassium allophanate), and can be used against some energized electrical equipment fires (USA class C fires). It has about 4–5 times more effectiveness against class B fires than carbon dioxide, and more than twice that of sodium bicarbonate. Some fire extinguishe…
P- break the tamper seal by pulling the pin on the extinguisher. A-Aim it low with the nozzle pointed at the bottom base of the fire. S-squeeze the handle firmly to release the extinguishing agent. S- sweep the nozzle from side to side while firmly pointing at the base of the fire until it is completely extinguished.

How does Purple K extinguish fire?
It is a potassium bicarbonate based dry chemical agent that extinguishes by changing flame chemistry and cooling. Purple K suppresses Class B (petroleum, oil, lubricant) and Class C (electrical) fires by interrupting a fire’s chemical reaction and cooling the flame/hot surfaces (endothermic reactions and surface cooling).
How do you remove purple K from spent fire suppression agents?
If the spent agent is dry it can be removed by suction, but when combined with water, hydrocarbons and other liquids, it forms a thick crusty scum that can be challenging to remove. Purple-K should never be mixed with phosphate -based fire suppression agents ( ABC dry chemical ), as the resulting chemical reaction will destroy its efficiency.
How does a fire extinguisher work?
The extinguishers leverage wet mist with alkaline mixtures in the form of potassium citrate, potassium acetate, or potassium carbonate. The alkaline mixture interact with cooking media to effectively quench the fire and reduce the risk of re-ignition
What is a Class K fire extinguisher made of?
Currently, the only effective extinguishers rated as Class K are the Wet Chemical Fire extinguishers that meet regulatory and industry standards. The extinguishers leverage wet mist with alkaline mixtures in the form of potassium citrate, potassium acetate, or potassium carbonate.
