Foam-water spray system?

Foam-water spray system?

• A. Foam-water Deluge System
• B. Foam-water Dry Pipe System
• C. Foam-water Preaction System
• D. Foam-water Spray System

Answer: (D)

Foam-water systems mix foam concentrate with water to create a foam solution that blankets and cools the fire. The spray system version is designed to deliver that foam-water through spray nozzles to produce a wide, spraying discharge that quickly coats surfaces and forms a foam layer over the fuel. This delivery method is what sets it apart from other foam-water arrangements: a deluge system releases foam-water through all heads with open sprinklers after activation, a dry-pipe system uses pressurized air in the pipes until the system is activated, and a preaction system requires a detection-triggered release before water enters the piping. Therefore, the foam-water spray system is the correct choice due to its spray-application delivery.
