Fire Safety Stick
It weighs far less than a conventional fire extinguisher and can operate for much longer. And best of all, there is NO residue left behind after use.
Environmentally friendly and can safely be stored for easy access in an emergency. The Fire Safety Stick will help you to contain a fire, preventing it from becoming a threat to life or property. In fact, for enclosed fires (eg. within a caravan) you can activate the Fire Safety Stick, leave it inside to extinguish the fire, as you get out to safety.
Unlike any other conventional extinguisher it needs no servicing, refilling, checks or maintenance and has no expiry date. No danger from pressurised containers which can explode or malfunction. Store the Fire Safety Stick in an easily accessible place. Strike the activator, point the nozzle at the base of the flames to smother the fire at its core.
Inside it’s a solid resin of Potassium nitrate. Once the chemical reaction begins, this is split into nitrogen gas (N2) which acts as the propulsion/creates the pressure. And potassium free radicals(K+) these have to bind onto the oxygen and so therefore take the oxygen away from the fire. By binding onto the oxygen they create potassium oxide (K2O). - very fine particles that blow away - totally inert.
How does the Fire Safety Stick work?
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). 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 stick to extinguish all types of fires through saturation, while its slow bio-degradation in the environment, further prevents the likelihood of subsequent fires. The extinguishing process involves two different reactions: one is physical and the other, chemical. The physical reaction relates to potassium’s tendency to oxidise rapidly in air. When in contact with air, alkaline salts consume great quantities of oxygen, thus depriving fires of oxygen. Then the chemical reaction is created through the stable link between potassium particles and the fire’s 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 fire’s natural chain reaction combustion process. Potassium has strong inhibitor qualities due to its weak ionization energies. The extinguishing agent being used is composed of Potassium Nitrate, organic oxidizer, and plasticizer resin. When Potassium Nitrate (KNO3) discharges from the extinguisher it vaporizes in the environment followed by the condensation of its extinguishing substance. When it reacts (inside the body of the extinguisher) it breaks down and the aerosol that is formed is made up primarily of free radicals of Potassium K+, of Nitrogen N (an inert gas), and water vapour. The aerosol that comes out of the unit reacts with the fire. Potassium radicals (K+) capture the Oxygen of the combustion thereby extinguishing it. At the end of the extinguishing process the following is discharged to the atmosphere: As a solid: particles of Potassium (that have reacted with the Oxygen of the fire) having a size between 3-4 microns. These particles are invisible at sight and heavier than air. They disperse in the atmosphere and tend to deposit on the ground in no appreciable amounts. As a gas: As Nitrogen; an inert gas which is already present in the air we breathe at more or less 78%. As water vapour (and lastly) extremely minimal toxic by-products that are a result of the combustion process.
