Fire department hose lines should operate from standpipe hose valves on which location in multi-story buildings?

• A. On the intermediate stair landing or floor below the fire floor.
• B. On the ground floor only.
• C. On the fire floor only.
• D. From the exterior of the building at hydrants.

Answer: (A)

The main thing this item tests is where firefighters should deploy a standpipe hose line in a multistory building to attack a fire safely and effectively. Placing the hose line at a standpipe valve on the intermediate stair landing or on the floor below the fire floor gives a protected, reachable position from which to advance the line up to the fire area. This keeps the operator out of the immediate heat and heavy smoke of the fire floor, reduces exposure to dangerous conditions, and allows for better control and coordination as you push the line toward the fire. Using a hose line from the ground floor only can force longer hose runs and heavier friction losses, and may not provide a practical or safe path to the upper floors once the fire is spreading. Limiting operation to the fire floor only would put the hose team directly in the hazardous zone, increasing risk. Operating from the exterior at hydrants does not utilize the building’s standpipe system, which is designed for interior attack and rapid deployment from within the structure.
