Choosing the Right Fire Extinguisher for Cooking Fires
When it comes to cooking fires, especially those involving combustible fats and oils, it is crucial to use the correct type of fire extinguisher. Fires involving these materials are classified as Class K fires. Therefore, the best fire extinguisher for this type of fire is:
- Class K Extinguisher: Specifically designed for kitchen fires, it utilizes a special agent that effectively cools and extinguishes the flames caused by cooking oils and fats.
- Class A Extinguisher: Used for ordinary combustibles such as wood and paper, but not effective for oil fires.
- Class B Extinguisher: Designed for flammable liquids, but does not address the chemical nature of cooking oil fires.
- Class D Extinguisher: Suitable for metal fires and not relevant in kitchen scenarios.
In summary, to ensure safety in the kitchen, always have a Class K extinguisher readily available if you are cooking with oils or fats.
