Installing standpipes in a building eliminates the need to:

• A. Use a pool of water
• B. Evacuate the building
• C. Stretch ladder from the street
• D. Stretch hose from the engine up to the fire floor

Answer: (D)

Standpipes provide a built-in water supply inside the building, with outlets on the floors where firefighters can connect hoses and push water directly to the fire area. Because of that, you don’t have to drag a large supply line from the engine up to the fire floor. This is why this option fits best: installing standpipes eliminates the need to stretch hose from the engine up to the fire floor.

The other ideas aren’t addressed by standpipes: they don’t remove the need to evacuate occupants, they don’t replace ladders for access, and they don’t create or rely on a pool of water outside the building.
