Stretching a 3in with a gated wye or a water thief up the side of the building to the floor below and then stretching off that has proved to be effective and fast in our department.I think you should forget about the standpipe and also the line up the outside. Modify at least one of your hosebeds to handle a long stretch and practice stretching to the fire floor.
We use it in Class 3 OMD's and use the half landing window or if not available an apartment on the floor below window. The operation goes surprisingly fast when you have a good engine company.What window does the line go into?
My department is currently using 2 1/2 for these building I am not in favor of this. I would prefer 1 3/4 as a first line backed up with the 2 1/2.My reasoning for this is speed and manuverability. Over the last
few years we've had several residential high rise fires and after
speaking to the 1st due nozzlemen I realized the difficulty with the 2
1/2 in residential occupancies given our manpower.Now structuraly a
fire resistive OMD is more forgiveing then a light weight wood frame
OMD (I think we can all agree on that) here in lies the basis of my
argument against the 2 1/2 as the initial attack line.
