Ray McCormack discusses advancing a 2 1/2-inch hoseline into a commercial building.
(music). Hi, I'm Ray McCormick and welcome to Training Minutes in this episode we're going to be stretching a two and a half inch line into a commercial building we've laid out our lead length a particular way to make our advance that much easier. Two and a half inch hose is a very hard to move line. By making a loop in our lead length, we'll be able to advance much easier into the fire occupancy. We won't be dragging as much hose along behind us. This loop will assist us with our forward motion of the line, enough to get us, at least, 25 feet in. They'll be able to advance, by themselves, just the nozzle team. We wanna place the first coupling back between lengths one and two, right near the entrance to the occupancy, and then fold our line back on itself and bring the nozzle towards the occupancy door. This does two things, it'll give us a measurement of how far in we are once we get in. And also it leaves half the hose at rest when were pulling only half the line in. If, the line is left on the street, as it normally might be, you will be dragging a lot more hose with you to make that initial entry. [BLANK_AUDIO] [SOUND] In this particular stretch, the nozzle team has not laid out the first coupling close to the entranceway. It is farther away. We're gonna pick up a lot of friction trying to advance into this occupancy by this nozzle team. [SOUND] Commercial building fires are difficult all by themselves. We don't need our hose line operation to make it anymore difficult. If we lay out the hose in a nice u shaped pattern, right in front of the main entrance door. Our initial entry to the store will be much easier. You wanna make it easy for yourself initially, it's gonna get more difficult as you advance deeper into the occupancy. Use this hose layout technique at your next commercial building fire. And I guarantee you a smoother, quicker, and easier advance. I'm Ray McCormick, and this has been Training Minutes. [MUSIC]
