Fire Hose Has A Dirty Secret.pdf
The fire service is once again focusing on a topic that garnered a lot of attention in the 80’s and 90’s. Many are now revisiting the concept of attaining higher than standard flows through 1.75-inch handlines. 1.75-inch handline flows of 250gpm are being considered. This flow in small diameter handline is, in many ways, damaging to all fire ground operations because it limits the functional envelope of the stretch to around 200 feet due to high friction loss. Creating two distinctly different flows from one size hoseline also adds to fire ground confusion by complicating pump operations and line selection.
