Stand pipes are needed in buildings where?

• A. Standpipes are not required in any building.
• B. Standpipes are only optional in high-rise buildings.
• C. Standpipes are only used for decorative purposes.
• D. Standpipes are required in buildings taller than 75 feet to the highest occupied floor or large one-story buildings.

Answer: (D)

Standpipes provide an on-site water source for firefighting inside a building, allowing hose streams to reach upper floors or large interior areas without relying solely on exterior hydrants. Codes require them where the building’s height or size would make a straightforward hose layout from the outside or from lower floors impractical. That typically means buildings taller than 75 feet to the highest occupied floor, or large one-story buildings where a centralized water supply is necessary to cover the entire space. In shorter or smaller buildings, standpipes aren’t required because other water sources and suppression systems are sufficient. So the correct rule is that standpipes are needed in buildings taller than 75 feet to the highest occupied floor or large one-story buildings.
