Which extinguishing approach is preferred for kitchens to minimize cleanup after discharge?

• A. Dry chemical
• B. Wet chemical
• C. Water mist
• D. Foam

Answer: (B)

Focus on the type of fire in a kitchen and the mess that follows discharge. Wet chemical extinguishers are designed specifically for commercial kitchen fires involving cooking oils and fats. They release a potassium acetate solution that saponifies fats, turning the oils into a soapy layer that both cools and seals the surface. This chemical action not only helps suppress the fire but also minimizes spread and residue, making cleanup much easier after discharge. Other agents tend to leave more difficult residue or create conditions that complicate cleaning: dry chemical leaves gritty powder that sticks to surfaces; water-based sprays or water mist can spread oil and create slick, slippery areas; foam can mix with oil and leave a mess. So, using wet chemical in kitchens offers effective suppression while simplifying post-fire cleanup.
