What is a Class K fire?

A Class K fire specifically refers to fires that involve cooking oils and greases, particularly those used in commercial kitchens. These types of fires require specialized extinguishing agents, as they can burn at very high temperatures and can spread rapidly if not addressed properly.

The Class K designation is important because it indicates the need for the right fire extinguisher types, which typically include wet chemical systems that can effectively cool and smother the flames while producing a chemical reaction that leads to saponification. This helps to create a barrier between the fuel and the fire, preventing re-ignition.

Understanding Class K fires is crucial for safety in environments where cooking takes place, as traditional fire extinguishing methods may not be effective and could potentially exacerbate the situation.
