FK-5-1-12 mechanism of suppressing fire is through physically cooling the fire at the molecular level. FK-5-1-12 is an efficient heat transfer agent and suppresses fire by absorbing heat energy at its molecular level faster than the generated heat. The removal of thermal energy from the fire causes
insufficient heat energy for combustion to occur. Additionally, free radicals are released into the fire to interfere with the chain reaction of the combustion process. This makes it a highly effective irefighting agent that is safe for people and causes no damage to equipment.
