pretty taboo unless your only option. If your stretching from the protected stairwell, it isn't protected anymore. Once that hoseline leaves the stairwell that door to the stairwell will have to remain open. If that fire apt. door is open then the hallway is considered the fire area and very dangerous. Not where I would want my control guy maintaining pressure in my line! Id have to say avoid at all costs.

With training you will find that stretching from the floor below is easier to manage hose. We hook-up on the floor below and flake all the extra hose in the hallway there. That "protected stairwell" is only protected until you enter the fire area. If there stairwell is a smoke proof stairwell beware that this may draft fire toward the nozzle team. You should leave this as your evacuation stairwell and stretch from a non-smoke proof stairwell.

This past summer I had a job, and due to Stack Effect, the smoke decended 4 floors in the stairwell. Fire can do the same thing if you have an EWD situation. Some guys think plenums are protected. They are not. Hook up one floor below. The backup line should be 2 floors below. If you don't have the hose or the manpower. Wait. That fire is not going anywhere.
