Williams’ “PKW™” is a highly specialized siliconized Purple-K that is one of the most effective dry chemicals used to extinguish flammable and/or combustible pressurized liquid fires. When used in conjunction with Hydro-Chem™ Technology it effectively controls and extinguishes pressurized or three dimensional “Class B” liquid fires. Its distinctively deep purple colour provides the fire fighter with the ability to stay ON-TARGET when projected to the fire within the foam and/or water stream. The result, when combined with Hydro-Chem™ Technology is the ability to achieve a quicker and more efficient “knockdown,” and extinguishment. Because it allows ON-TARGET delivery, it reduces waste, post-extinguishment cleanup efforts and costs.
Williams” “PKW™” is a potassium bicarbonate based dry chemical containing colourised additives. The agent is free-flowing, water repellent and non abrasive and, when used as a fire extinguishing agent, will produce no toxic effects. “PKW™” dry chemical is available in 22.6kg plastic pails.
