Answer :

Final answer:

Wet chemical extinguishers are effective for CLASS F fires because they cool the burning fats and form a smothering film to cut off oxygen. The potassium acetate solution makes them specifically tailored for kitchen fires. Their operation allows for safe extinguishing without hazardous splatter.


Explanation:

Why Wet Chemical Extinguishers are Suitable for CLASS F Fires


CLASS F fires involve cooking oils and fats, which are common in kitchens and require specialized fire extinguishing agents due to their unique properties. A wet chemical extinguisher is specifically designed to tackle these types of fires effectively. Here are some key reasons:



  2. Cooling Effect: Wet chemical extinguishers work by cooling the burning oil below its ignition temperature, which rapidly reduces the heat.

  4. Chemical Reaction: They contain a solution of potassium acetate, which creates a surface film on the burning oil. This film helps to smother the fire by preventing oxygen from reaching the fuel.

  6. Acting Safely: Wet chemical extinguishers can be used at safe distances from the fire, minimizing the risk of splashing burning oil or fat back at the user.


Overall, the wet chemical extinguisher's design and chemical properties make it uniquely suited for dealing with CLASS F fires, ensuring safety and effectiveness in kitchen environments.
