What type of extinguisher rating is required for cooking appliances?

The appropriate extinguisher rating for cooking appliances, particularly those involving oils and fats, is a Class K extinguisher or a 2-A rated water-type extinguisher. Class K extinguishers are specifically designed to combat fires that occur in commercial kitchens, fueled by cooking oils and greases. These extinguishers contain agents that can effectively suppress fires involving such flammable liquids.

In addition to Class K extinguishers, a 2-A rated water-type extinguisher can also be suitable for certain cooking environments because it is effective against ordinary combustibles, although it may not be as effective against the specific hazards posed by cooking oils. Therefore, having a Class K extinguisher in environments where cooking appliances are used is crucial for enhancing safety and ensuring the appropriate response during a fire incident.
