We are currently revamping our departments High Rise SOG. Long story short during training of stretching hose in an uncompromised stairwell we were reinforcing looping your nozzle section up the stairwell above the fire floor. During this we have come across an officer who states that "we never stretch an uncharged hose line above the fire floor." Of course I am not an officer and I happened to be doing the training the date this statement was made, lucky me. I am pretty up on my knowledge and took in the comment and tried to refer him to Chief McGrail's books and articles primarily the 'stairwell stretch', but was un successful. He insisted that no matter what the situation, even in an uncompromised stairwell, we never stretch and uncharged hose line above the fire floor. I agree with the officer in certain situations his statement is true, but not in this one. I was looking for other opinions/views and if anyone has anything to back up the officers claim. Thanks.
