Wet Chemical Fire Extinguisher
Three minutes is more than enough for turning a small flame into a big fire with the typical Class K fire. Class K fires involves cooking oil, fats, butter, lard etc. It usually starts from kitchens and cannot be extinguished using simple water. This is because oil is lighter and it forms a layer above water and keep burning.
Simple water will rather cause the oil to flow over it and this will transport fire to larger areas. Similarly extinguishers such as CO2, foam and powder will not be able to put out the big fire rather the pressure will cause the oil to spread out and cause more damage. For this purpose wet chemical fire extinguishers are used.
How Does Wet Chemical Fire Extinguisher Work?
Wet chemical fire extinguisher is a special kind of chemical based fire extinguisher that react with burning hot fuel (cooking oil, butter, wax etc.) and turn that fuel into soap which is almost impossible to burn. The mist of spray works as a coolant and brings the temperature of the burning area down to stop the fire from spreading further. They are highly efficient in their performance and can put off fire within a quick period of time by spraying over a small flame.
