Where should hose connections be located for Class I standpipes?

• A. At the end of the building corridor.
• B. In the corridor or space adjacent to the stairway enclosure.
• C. In the exterior courtyard.
• D. In the mechanical room.

Answer: (B)

Hose connections for Class I standpipes should be located in the corridor or in a space adjacent to the stairway enclosure. This placement keeps the connections easily accessible from the main egress paths on each floor, so trained personnel can quickly locate and deploy the 2.5-inch hose without delving into tenant spaces or locked rooms. Placing them near the stair enclosure also places the connections close to the vertical fire barriers and the primary means of egress, facilitating rapid firefighting operations as crews move through the building. Choosing an exterior courtyard or a mechanical room would hinder access during a fire: exterior spaces are not readily reachable from interior corridors under smoke conditions, and mechanical rooms are often locked or obstructed and not present on every floor. End-of-corridor locations can also be less reliable if that portion of the corridor is blocked or not immediately obvious, whereas a corridor or space by the stairs is a consistent, recognizable, and protected location across floors.
