Russ - Our pumpers are generally set up with three static hose beds for attack lines. Two 1/34 beds and one 2 1/2 bed. FDNY policy for the 1 3/4 hosebed is that you can have up to six lengths of 1 3/4 filled out by 2 1'2 hose. you can have less if you choose. We do not attach the two lines with a water thief or wye's. FDNY does not use preconnects for structural fires, One of the reasons is that each engine back stretches and gets its own water supply at the hydrant.
We have a lot of beach front property that has a zoning option of building up to floor stories. The problem is this does not include the FEMA mandated piers to keep the building out of the flood zones, so now the buildings are 5 stories. We were a strickly preconnect town, but a few good thinking heads put together and now we have the static load option. We increased it to 6 lengths with a SB nozzle recently, but I am haveing training issues as the men are used to TFTs and not having to worry about the kinks as much. On my own engine, the guys prefer the SB and pull it all the time, it is the OTs and detail men that we have problems with. We also have 12 lengths of 3" with a gated wye, and we have the option to back stretch, ( hydrants are not a problem here, evey 300 feet). When I lived in CA, we had a skid load of 2 150" lines connected up to a wye in the same configuration, lying on a tarp. We just dragged the whole tarp, and it fell to the ground, ( our hosebeds were low). Then the engine back stretched. It worked OK, not the best.
Worked RIT with Paul Debart this week;....great guy. Good fireman.
We do not have any static 1&3/4 beds. We run two 200 ft X 1&3/4 preconnects and two 150 ft X 1&3/4 hose packs that can be connected to a wye or leader tip off the 2&1/2 inch hose. OUr 2&1/2 static bed is 600 ft. We also have a 200 ft X 2&1/2 preconnect. All 2&1/2 inch hose as well as the 1&3/4 hose packs have SB nozzle.
The combination of a long 2 1/2 static hose bed (600') and (150") of 1 3/4 hose pack, works well. A problem that occurs with this type of ADD on stretch is misjudging 1 3/4" portion of the stretch. Often its short of the objective but more often its too long, with the 21/2 being stretched close and the excess hose in need of a good flaking spot. Firefighters using this type of stretch need to think about how far three lenghts of 1 3/4 hose will take them in the fire building and stop the 2 1/2 at the correct spot. Had they been connected to start with, makes the stretch math easier as the line is seen as one and not an ADD on feature.
Ray...what do you do if you stretch too long? Do you loop the line down the hallway, take it back downstairs, open an adjacent apartment and place it in there? Does FDNY have the first engine officer go in independently to determine the length of stretch, and then the control makes sure the proper amount is stretched?
The way it is usually done is the Engine officer enters and if it is a large building determines the best route for the hoseline. If the building is a standard one stairway building the officer will look for any unusual features that may impact the stretch. The control FF will be estimating the stretch based on the 5 standard stretch features. Additional hose may end up near the fire floor or in the street. All the methods you mention may be used. over stretching is fine as long as it is not way over.
Okay, not to drag out the questions but is the control guy the one who makes this connection? This is a stretch that works well for FDNY and is that because your Engines are staffed with 5? Thanks Ray.
