Uses
Purple-K is commonly used in oil refineries, airport ramps, service stations, military facilities, naval warships, power plants, and other places where flammable liquids are handled. It is often paired with foam in twin agent systems, usually found fitted to airport fire appliances.
Purple-K is used in many forms, from small handheld fire extinguishers to large mobile and stationary units, including fixed-nozzle piping systems.
Cleanup of spent agent can be difficult, as it creates a mess when discharged. 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.
