1¾-inch and two-inch diameter hoselines are effective in residential firefighting because they flow sufficient water to rapidly control one or two rooms of fire and have the mobility to be easily advanced up stairs and around corners and furniture. Firefighters may encounter a problem when their hoseline must extinguish a first-floor fire before ascending to the second floor to stop any vertical extension. In this situation, there is no opportunity to “stretch dry” to the second floor or stair half-landing because the hoseline has already been charged and operated on the first floor. Advancing a charged hoseline up a stairway and operating it on the second floor usually requires three firefighters at minimum, who may not be immediately available if the first-due engine has a crew of three, including the driver-engineer: One is positioned at the base of the stairs to pull hose and feed it up the stairs; a second firefighter is at the top of the stairs to pull the hose up and then feed it to the nozzleman (the third firefighter) for the advance down the second-floor hallway. When only two firefighters are available to perform this operation, the following technique can be effective.
Photo 1. The nozzleman brings the charged hoseline nozzle-first into the stairway and positions himself at the bottom of the stairs to the second floor.
