What is the function of a standpipe connection in a high-rise incident?

• A. To vent smoke from the lower floors.
• B. To connect to a standpipe in the lower floors for drainage.
• C. To provide a pressurized water supply to floors above the pump operator's position.
• D. To support the building's fire alarm system.

Answer: (C)

The standpipe connection is the bridge that brings water from the fire department’s apparatus into the building’s standpipe system, delivering a pressurized water supply to floors above the pump operator’s position. In a high-rise, the standpipe network carries water up the building, and firefighters on upper floors rely on hose lines connected to those standpipes to attack the fire without hauling long, heavy hose up many flights of stairs. The pump operator powers water into the standpipe through this connection, ensuring adequate pressure and flow where firefighters need it most.

This function isn’t about venting smoke, draining water, or operating the building’s fire alarm system, so those options don’t apply.
