A potassium bicarbonate-based dry chemical agent for Class B flammable liquid, gas and grease fires, including fires involving energized electrical equipment (Class C).
ANSUL (Johnson Controls)
ANSUL Purple-K is one of the most effective dry chemical agents available against Class B fires. It is a potassium bicarbonate-based powder containing chemical additives, produced by an exclusive ANSUL chemical process. The result is a free-flowing, water-repellent, non-abrasive agent that produces no toxic effects when used as a fire suppressant. Its distinctive purple colour sets it apart from other dry chemical agents.
Purple-K is designed for fires in flammable liquids, gases and greases (Class B), and remains effective where those fires involve energized electrical equipment (Class C). Because of its proven firefighting performance, it is widely used in the petroleum industry and other high-risk environments. In extinguisher applications, Purple-K has been shown to be at least four to five times as effective as carbon dioxide, and more than twice as effective as sodium bicarbonate-based agents.
The agent is used across a wide range of delivery systems, from hand-portable and wheeled extinguishers to large stationary units, mobile units and fixed-nozzle piped systems. Extinguishers charged with Purple-K operate at temperatures from −54 °C to 49 °C. After a fire, clean-up is simple with a vacuum cleaner or a broom and dustpan.
Caution: Never mix Purple-K with phosphate-based dry chemicals. The resulting chemical reaction will damage the extinguisher. After discharge, extinguishers must be refilled only with the original agent specified on the nameplate.
Industrial Fire & Hazard Control supplies ANSUL Purple-K with refill services and full technical support across Southern Africa.
