Which are the four types of Sprinkling Systems?

• A. Flush Deck, Bilge, Overhead, and Deck Edge
• B. Deck Edge, Bilge, Overhead, and Firemain
• C. Flush Deck, Deck Edge, Bilge, and Overhead
• D. Flush Deck, Deck Edge, Bilge, and Overhead

Answer: (C)

The four types are flush deck, deck edge, bilge, and overhead sprinkling systems. This grouping covers the main areas where fires or fuel spills can occur during AFFF transfer operations: flush deck sprinklers wash and cool the deck surface to prevent reignition; deck edge sprinklers form a perimeter to help stop flame spread from the edges; bilge sprinklers address the lower spaces where liquids can pool and vapors can collect; overhead sprinklers spray from above to cool and knock down heat across the working area. The other options mix in terms like firemain or omit one of these zones, so they don’t reflect the standard set used for comprehensive coverage.
