What is the primary purpose of a standpipe system in a multistory building?

• A. Automatically boost the sprinkler system pressure
• B. Be utilized only with Class II standpipe operations
• C. Deliver water to each floor of a building
• D. Reduce the pressure at non-operating sprinkler heads

Answer: (C)

Standpipe systems provide a ready water source on each floor of a multistory building so firefighters can pull a hose and fight a fire on that level without having to bring water all the way from the street. The vertical piping carries water from a building or municipal supply to outlets on multiple floors, giving crews quick access to water where the fire is happening. This is why delivering water to each floor is the primary purpose. The other ideas miss the core function: standpipes aren’t about automatically boosting sprinkler pressures, they aren’t limited to a single type of standpipe operation, and they aren’t used to reduce pressure at sprinkler heads. The key goal is to provide accessible water on every level for firefighting.
