The Fire Risk Alliance conducted a series of tests to determine the efficacy of FireIce® in extinguishing lithium-ion battery fires. The first goal of the test series was to compare the suppression performance of a 2.5-liter FireIce® extinguisher on a lithium-ion battery fire to that of a 2.5-pound Halon 1211 fire extinguisher. In the immersion of lithium-ion batteries, FireIce® demonstrated the ability to cool and create the thermal barrier necessary to extinguish. The FireIce® extinguisher was able to cool and prevent cell-to-cell fire spread extinguishing the battery fire.
