What is the effective range of a potassium bicarbonate (PKP) portable extinguisher?

The effective range of a potassium bicarbonate (PKP) portable extinguisher is typically between 19 feet to 21 feet. This range allows the operator to effectively discharge the extinguishing agent onto the fire while maintaining a safe distance. PKP is commonly used for Class B fires, which involve flammable liquids and gases, and the ability to reach this effective range is crucial for both safety and effectiveness in controlling such fires.

Understanding the effective range helps personnel to operate the extinguisher properly, ensuring that they can reach the fire without putting themselves in hazardous proximity to the flames or toxic fumes. Familiarity with this specification is essential for safe firefighting operations aboard naval vessels and in other environments where these extinguishers are employed.
