Selecting hose for your high-rise hose pack is a series of trade-offs. It would be great to have 250 of 2″ or 2½” hose, but that will quickly prove impractical for carrying up many flights of stairs. Instead, aim for 150 feet of 1½”, 2″ or even 2½” hose. One or two firefighters in good shape can usually carry this hose pack. Important: Choose lightweight hose for a high-rise hose pack, even if this requires compromising on the flow. Also ensure your hoseline has a service pressure rating of 300 psi (the normal pressure rating for attack hose) or more and minimizes friction loss at the flows you need to achieve.
