What type of fires is classified as Class K?

Class K fires are specifically associated with kitchen or cooking environments, primarily involving combustible cooking oils and fats. This class of fire is particularly critical to recognize in settings where cooking is done because it requires distinct firefighting methods and extinguishing agents that are different from those used for other types of fires.

The nature of Class K fires stems from the high flash points and the potential for rapid flame spread when oils and fats ignite. Common extinguishers for Class K fires contain agents designed to cool the flames and create a barrier between the fuel and the oxygen in the air, effectively preventing re-ignition. This specialized approach is crucial for ensuring safety in culinary areas, making the classification essential for fire guard training and safety protocols in shelters and kitchens.
