FirePro® aerosol extinguishes fire by inhibiting the chain chemical reactions present in combustion on a molecular level.
Theory of Fire – Fire Extinguishing: Traditionally, there were three distinct elements assumed as necessary for combustion: heat, fuel and oxygen, popularly known as the “fire triangle”. Typical fire extinguishment involves either removing the fuel from the fire, limiting oxygen to the fire (smothering) or removing the heat (quenching).
This theory had to be modified as other agents like FirePro do not extinguish fire in any of these ways, but instead break up the chain reaction of the combustion process. Upon activation, FirePro starts a chemical reaction that in few seconds produces aerosol (i.e. potassium compounds (K2CO3), H2O, N2, CO2 and other gases in small quantities.
FirePro remains in suspension for a relatively long time in the protected volume allowing it to flow into the combustion core breaking the chain reaction upon flame contact with extremely high efficiency.
The fire tetrahedron is an addition to the fire triangle. It adds the requirement for the presence of the chemical reaction which is the process of fire. Combustion is the chemical reaction that feeds a fire more heat and allows it to continue.
