K Class Type

Principle of Operation:

Class K Extinguishers work on the principle of saponification. Saponification takes place when alkaline mixture such as wet chemical (Mixture of potassium acetate, potassium citrate, or potassium carbonate) is applied to burning Oil or fat, the wet chemical combined with the fatty acid creates a soapy foam layer on the surface which holds in the vapors and steam and extinguishes the fire.

Why can’t we use Multipurpose ABC Fire Extinguishers rather Kitchen Fire Extinguishers (Wet Chemical)?

Changes in frying oils from animal fats to vegetable oils have reduced the ability of Multipurpose ABC Fire Extinguishers to extinguish many kitchen fires. As we know Vegetable oils have a much higher auto ignition temperature than animal fats because of this Heat breaks down the weaker foam layer created and re ignition takes place.

Kitchen Fire Extinguishers have the ability to maintain the foamy layer enough to allow complete cooling.

In addition, these wet chemical agents pose minimal damage threat to hot appliances.
