Product Description

Williams PKW (Purple-K), also known as PK Vivid, is mainly used in twin agent (PK/Foam) systems such as the Williams Firefighting Hydro Chemical Nozzle used in the petrochemical industry. Containing 2.05% of purple dye (compared to 0.0143% in Ansul Purple-K), PKW is specially formulated to produce a highly-visible dark violet stream to guide firefighters while being discharged in tandem with water. The 50 lb pail is Ansul part # 423650.

Like Ansul Purple-K, Williams PKW is used to combat fires involving flammable liquids, gases and greases (Class B) including such fires when involved with energized electrical equipment (Class C).

PKW is one of the most effective dry chemicals against Class B fires. It is a potassium bicarbonate-based material containing chemical additives. The resulting agent is free-flowing, water-repellant, non-abrasive and, when used as a fire extinguishing agent, will produce no toxic effects. Purple-K is violet in color to differentiate it from other dry chemical agents. Cleanup is readily accomplished with a vacuum cleaner or a broom and dust pan.

Purple-K is at least 4 to 5 times more effective in extinguisher applications than carbon dioxide and more than twice as effective as sodium bicarbonate-based extinguishers. This agent is approved or listed by nationally recognized testing laboratories and meets U.S. and Canadian government specifications. Caution: never mix this agent with phosphate-based dry chemicals. A chemical reaction will take place that is harmful to the extinguisher.

The shipping weight of the pails is 54 pounds (24.5 kg) and there are 36 containers per pallet. Given the heavy weight, a fixed shipping charge of $20 per container will be applied to your order at checkout which is valid only for ground shipment within the lower 48 US states. If you need rush delivery or delivery outside this area, you can contact us before ordering, otherwise, we will contact you with the actual freight costs before processing your order.

Purple-K is also available in 200 and 400 lb drums. See item #'s 09454-200 and 09454-400 for pricing.
