High Rise Pack
What does your department use of a High Rise Pack? Size and length of hose? Nozzle selection? Any other equipment it the pack?
Our city has recieved conceptual plans for two 12-14 story hotels in our city and I am wondering what other departments use for carry up fire protection. Currently, our largest building is 3 stories. We use 100 feet of 1-3/4 inch attached to a gated wye. This is hooked into a play pipe which is hooked up to 2-1/2 inch hose. The playpipe has a shutoff built into it and stacked tips down to 2 inches to hook into the gated wye. The open end of the gaed wye has a combination nozzle on it so all that is needed is extra hose to hook into the wye, the nozzle is already there. The whole thing is packed using a Milwaukee strap designed for hotel packs.
Our current regulations require standpipes in all commercial and public buildings 2 stories or more. They are talking about 2 separate water mains, pumps, and water towers for fire protection and to help boost pressure for the hotels (or in the case of the towers the nearby area).
Oh, did I mention that there is word of the hotels subsidising for a replacement ladder for their protection.

We have several hi-rises in our city. All of them being elderly/low income housing. We carry 200 feet of 2" rubber jacket type with a solid bore nozzle. In the kit are spanner wrenches, hose straps, different type adapters. We run with four man engine companies and find we get the water we need with the 2" line and are still able to control it.

In our dept. we carry 100' of 1 3/4" hose with a low pressure automatic nozzle. Behind the auto nozzle we have a slug tip with a 15/16" smooth bore tip when we have to low a pressure for the automatiic.We also carry a 2 1/2" by 1 1/2" gated wye and a 2 1/2" to 1 1/2" reducer for the tight spaces.We have several highrise buildings in our city, and our biggest ladder is a 50' squrt.We run with two trucks and 4 man total shift strentgh . Sometimes were down to 3 man shifts.Thank goodness for off-duty and mutal aid.

We carry everything in ripstop nylon bags that are proving to be too bulky and obnoxious...I think most of the crews are about ready to strap a load together like you have. What we carry in them is: 200' of lightweight 2 1/2" w/1 1/4" or 1 1/8" (open bore)tips, 2 1/2" gated wye, spanners, pipe wrench...couple of stations have put a 3-5' length of 2 1/2" (or 3") to facilitate hookups. (Each bag has 100' of the hose...) We decided to go with the open bores because many of our bldgs have PRV's. A few stations have put assorted small things in their bags...door chocks, hose straps/ropes, etc. All other equipment is brought with the crew. Ideally we want 4 men on each crew but sometimes have 3; 2 guys usually carry one bag because of the bulk. At one point we tried strapping a "load" to a 2 wheeled dolly thinking that would be easy to move...however they had so much stuff on there that 2 guys could barely move it up stairs; more dollies with less load may have worked better but one of the Chiefs found a "deal" on the bags....

One thing to add...we use a lightweight, single jacket rubber lined hose in our "hi-rise" packs...they take up less space and weigh significantly less than traditional double jacketed.
Of course, they won't take as much abuse over time, but they're not used too often, and they have a distinctive color (int'l orange...yuck!) so they don't get mixed in with the rest of our hose!

I got one for you guys to think about. We all know the need for making the loads we carry up as light as possble such as in using lightwieght hose. Well guess what? The method used for making lightwieght hose is to reduce the material in the hose construction. Unfortunatly this also reduces the kink resistane capabilities that the hose has. In a highrise application this could be a critical problem because of the low pressures that NFPA has designed into our highrise building fire protection systems. We tend to judge thw weight of our equipment based on how much one firefighter can carry up the stairs. Funny thing is that when we get the big one in a highrise there usually is alot more than just one firefighter to do the job. Let's share the load. whoever said that the hose pack had to have the complete attack line connected in one pack? Don't sacrifice hose quality for less wieght

Big Paulie brings up a good point -- evaluate your hose carefully...there's big differences even within the same manufacturer's lineup.
Angus, for instance, lists 1.75" hose with FL of 42psi/50'@200gpm or 30psi/50'@200gpm, dependig on the materials and construction.
Also points out depending on pressure and flows desired, 2" and 2.5" hose isn't a bad idea...
Worse Case/Best Case examples using the Angus Charts:
1.75" Jacketed Hose, 150', 200gpm = 126psi friction loss
2.5" Rubber Covered, 150', 200gpm = 24psi friction loss
If your jurisdiction has tall buildings and PRVs, etc...you may just plain not have the PSIs to generate high flows in small lines!
So while you're looking at kinking, also check out weight, friction loss, and "stickyness" -- how easy is the hose to pull! Everything will be a compromise in the end...hopefully the best compromise for your own situation!
