Ansul Purple-K Class BC Extinguisher Powder, 50 lb pail

Ansul Purple-K is used to combat fires involving flammable liquids, gases and greases (Class B) including such fires when involved with energized electrical equipment (Class C). This agent is widely used in the petroleum industry and in other areas where the fire risk is high. The 50 lb pail Ansul part # is 9335.

Purple-K 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 normally 24 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.
