I'm looking at requirements for hose valves (FHV) at exit passageways and I'm a little confused.
The code states that a hose connection is required: "in every exit passageway at the entrance from the exit passageway to the other areas of a building.
Exception: Where floor areas adjacent to an exit passageway are reachable from exit stairway hose connections by a 30-foot (9144 mm) hose stream from a nozzle attached to 100 feet (30 480 mm) of hose, a hose connection shall not be required at the entrance from the exit passageway to other areas of the building."
What is the rationale behind locating a hose valve at the entry of the exit passageway?
Is this for fighting fires outside?
I have been told it is so that the fire department can quickly locate the hose valve, but I can't imagine they would want to run their hose 130-feet in the passageway just to then have another connection in the stairwell. My passageway is about 100-feet long and it connects to a stairwell that does have a fire hose valve located at the main landing.
Why would I need a fire hose valve at the entry of the exit passageway also, which is 100-ft away?
