Purple-K, also known as PKP, is a dry-chemical fire suppression agent used in some dry chemical fire extinguishers. [1] 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).

The fire blanket must be sealed closely to a solid surface around the fire. Fire blankets usually have two pull down tails visible from outside the packaging.
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
