In a multi-story building with a standpipe system, the connection should be made on which floor relative to the fire floor?

• A. On the floor above
• B. On the floor below
• C. On the same floor
• D. In the basement

Answer: (B)

In interior standpipe operations, water pressure and safe handling are strongest when you minimize vertical lift and keep the connection out of the immediate fire area. Connecting on the floor below the fire floor puts the attack line in a safer, more accessible spot while still allowing water to be moved up to the fire floor. This position reduces friction losses and the required pump head compared to tying into a standpipe on or above the fire floor, which would push water farther up the vertical column and into a hotter, more hazardous environment. From the floor below, firefighters can advance a hose up to the fire floor with adequate pressure and control.
