How is WCFS activated manually?

• A. By a readily accessible manual pull station.
• B. By turning a valve on the agent cylinder.
• C. By flipping a switch on the electrical panel.
• D. By waiting for automatic discharge.

Answer: (A)

Manual activation of a Wet Chemical Fire Suppression System is accomplished by pulling a readily accessible manual pull station located at or near the kitchen hood. This action mechanically releases the agent from the storage vessel and directs it through nozzles into the hood, duct, and cooking surface to suppress the oil fire. The pull station is designed to be quick to operate, requiring no tools and clearly marked for fast use in an emergency. This method is preferred for immediate control during a fire, whereas turning a valve on the cylinder, flipping a switch on an electrical panel, or waiting for automatic discharge do not provide the rapid manual initiation needed in cooking-oil fires.
