Description
PKW is a highly specialized siliconized Purple-K that is one of the most effective dry chemicals used to extinguish flammable and/or combustible liquid fires. It is proven even more effective when used in conjunction with The Hydro-Chem™ Handgun Technology to extinguish pressurized or three dimensional liquid fires. Williams Fire & Hazard Control PKW is a potassium bicarbonate-based dry chemical containing chemical additives. The agent is free-flowing, water repellant, non-abrasive and, when used as a fire extinguishing agent, produces no toxic effects.
Its distinctive, deep purple color provides the firefighter with the ability to stay on target when the dry chemical is projected to the fire within the water/foam solution stream. The result, when combined with Hydro-Chem™ Technology, is the ability to achieve a quicker “knockdown”, in addition to using less chemical to complete the job.
