Purple K
Dry Chemical Extinguishing Agent
Fast. Efficient. Environmentally friendly.
Kidde strives to recognize the environmental impacts of extinguishing agents. Our solution is Purple K, a fast, efficient, environmentally friendly fire suppression agent.
It is a potassium bicarbonate based dry chemical agent that extinguishes by changing flame chemistry and cooling. Purple K suppresses Class B (petroleum, oil, lubricant) and Class C (electrical) fires by interrupting a fire's chemical reaction and cooling the flame/hot surfaces (endothermic reactions and surface cooling).
In comparison to water-based extinguishing agents, water is undesirable for a Class B fire because it can spread the flames, and it is undesirable for a Class C fire due to potential shock hazards.
Comparison of Purple K to Other Agents
