Cold Fire™ is an environmentally friendly fire extinguishing agent that puts out ANY fire faster, safer, with less water, less damage to property, and less risk to firefighters. Cold Fire cools 21 times faster than water, and works to remove heat and the fuel sources from the fire tetrahedron, preventing reignition. Completely ‘green’ and non-toxic, Cold Fire puts out any Class A or B fire, hydrocarbons or polar solvents, as well as metals, tires, and asphalt and more. Also suppresses vapors and helps to remediate spills. UL Classified, 2N75
