In a commercial kitchen, the WCFS is designed to discharge specifically in response to heat in which area?

• A. The entire restaurant interior.
• B. The dining area
• C. The protected kitchen hood space.
• D. The outdoor patio

Answer: (C)

The system is designed to discharge in the protected kitchen hood space. In commercial kitchens, the primary fire risk comes from cooking oils and fats that ignite near the cooking equipment and within the hood and exhaust plenum. Placing the heat detectors and release components in the hood area ensures that the wet chemical agent is released right where the fire would start, coating surfaces and forming a soapy layer that saponifies fats, cools the oil, and helps prevent re-ignition. This focused protection also helps prevent the flames from spreading through the ductwork and keeps the rest of the dining area or exterior spaces from unnecessary discharge.
