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). [2]
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.

The larger the burn pan fire, the larger the rating and the longer the extinguisher must discharge to be able to handle the larger volume of fire before running out. For a given size extinguisher the resulting effect is a lower flow rate, resulting in a higher UL rating. Generally for same size extinguishers (agent capacity)
Gaseous fire suppression, also called clean agent fire suppression, is the use of inert gases and chemical agents to extinguish a fire. These agents are governed by the National Fire Protection Association (NFPA) Standard for Clean Agent Fire Extinguishing Systems – NFPA 2001 in the US, with different standards and regulations elsewhere.

For a fire to burn, all three elements of the fire triangle must be present: heat, fuel and oxygen. The fire blanket is used to cut off the oxygen supply to the fire, thereby putting it out. 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.
