The Fire Safety Stick (FSS) is a manual, portable fire extinguishing device. It uses a potassium powder jet (a unique method among conventional fire extinguishers) that employs the vaporisation of the powder in the environment followed by the condensation of its extinguishing substance. It works by interrupting a fire's chain of reaction (the "auto-catalyst" of the fire), effectively extinguishing a fire without making any mess or removing surrounding oxygen. Fire Safety Stick is composed of stable, solid minerals; it does not contain gas and is not pressurised. The aerosol-like jet is only produced when the charger is struck with its base. The produced aerosol jet is free of thrust and is essentially an inert salt that emits gas already present in the atmosphere.


This process allows the FSS to extinguish all types of fires through saturation. It's slow bio-degradation in the environment furthers the prevention of subsequent fires / re-flash. The extinguishing process involves two different reactions: one is physical and the other, chemical. The physical reaction relates to potassiums tendency to oxidise rapidly in air. When in contact with air, alkaline salts consume great quantities of oxygen, thus depriving fires of oxygen. The chemical reaction is created through the stable link between potassium particles and the fires combustion particles. Through the two reactions, a quick oxidation process takes place, immediately transforming the jet from a solid state into a gaseous state freeing the potassium particles. These atoms are able to intercept and interrupt any other free particles produced by the fires natural chain reaction combustion process. Potassium has strong inhibitor qualities due to its weak ionisation energies. The extinguishing agent being used is composed of Potassium Nitrate, organic oxidiser and plasticisers resin. When Potassium Nitrate (KNO3) discharges from the extinguisher it vaporises in the environment followed by the condensation of its extinguishing substance. When it reacts, it brakes down and the gas that is formed is made up primarily of free radicals of Potassium K+, of Nitrogen N (an inert gas) and water vapor. The aerosol that comes out of the unit reacts with the fire. Potassium radicals (K+) attaches itself to the oxygen surrounding the fire robbing its ability to stick to the chain of combustion thereby extinguishing it and preventing a re-flash and all the time not affecting ones ability to breath that oxygen.
