What is the function of standpipes during high-rise firefighting?

• A. Deliver water to interior firefighters on upper levels.
• B. Provide ventilation.
• C. Provide electrical power.
• D. Support scaffolding.

Answer: (B)

Standpipes in high-rise firefighting are water distribution systems that deliver water to interior crews on upper floors. They connect to the building’s water supply (and often a fire pump) and provide pressurized water to outlets on each floor. Firefighters attach hoses to these outlets and push water up the standpipe riser to where they’re working inside the building. This setup makes it possible to attack fires on higher levels without lugging heavy supply lines up stairs, which is essential for effectiveness and safety during a high-rise operation. Ventilation, electrical power, and scaffolding serve different roles: ventilation removes smoke and heat, electrical power isn’t provided by standpipes, and scaffolding is a separate support structure.
