• B. To deliver water for firefighting
• C. To supply power during outages
• D. To serve as an evacuation route

Answer: (B)

The primary function of a standpipe system in a building is to deliver water for firefighting. Standpipe systems are essential components of fire protection systems that allow firefighters to access water quickly and efficiently from various points within a building during an emergency. These systems are designed to provide water to a hose connection within the building, enabling firefighters to combat fires effectively without needing to bring hoses up from the ground level.

Standpipe systems are typically found in multi-story buildings where it may be impractical to transport large amounts of water up to the upper floors quickly. They ensure that firefighters have the resources needed to extinguish fires, thereby enhancing the overall safety of the building and its occupants. This system is especially critical in high-rise structures, where fire can spread rapidly and immediate access to water is vital for effective firefighting operations.
