What is the minimum percentage of foam recommended for Class A fires using Firebull A/B?

The minimum percentage of foam recommended for Class A fires using Firebull A/B is 0.25%. This percentage is crucial because Class A fires typically involve ordinary combustible materials like wood, paper, and textiles. The use of foam enhances the effectiveness of water by creating a blanket that suppresses fire and prevents re-ignition.

Firebull A/B is specifically formulated to function effectively at this concentration, providing sufficient coverage to smother the flames and offer better cooling for the exposed surfaces. Using the recommended percentage ensures optimal performance of the foam, enhancing firefighting strategies for Class A incidents while maintaining safety and efficiency. This minimum percentage reflects the balance needed for effective fire suppression without wasting resources or compromising safety measures during firefighting operations.
