In the event of a battery fire, the FirePro active agent consisting of potassium salts (K2CO) neutralizes the electrolyte’s decomposition products, such as Hydrogen Fluoride (HF). This prevents the formation of highly flammable gases such as Hydrogen (H).

The resulting neutralizing action ultimately controls the fire and allows the temperature in the enclosure to drop below the threshold necessary for the thermal runaway to sustain itself.
