[pause] [music] Hi, I'm Mike Wilbur. Welcome to Fire Engineering Training Minutes. In today's segment, we're going to educate you and explain to you how to properly deploy a [INAUDIBLE] ladder pipe at the scene of a structural fire. As you look at this apparatus you'll not that it has a pre-piped water way. This pre-piped waterway is a what the industry refers to as a pentable waterway. In the position that you see the waterway at the present, it is pinned back off the fly section and it is pinned in what we call the rescue mode. Firefighters now can use the ladder. For, survey and rescue, they can use the ladder to access roofs and windows, they can use the ladder to even ventilate windows without having the fear of damaging the water nozzle. Once we've established that we're going to use the water nozzle, we are going to then pull the pin out of the pinnable water way. And if I could have that pin please, we would like to show our audience this pin. This pin in an integral part of this assembly. Right now we've started with the apparatus in the rescue mode that frees up the tip of the ladder for rescue. windows, ventilating windows. We can access roofs, we can access windows, without fear of damaging the nozzle assembly. This pin is what holds the nozzle assembly into place. We've taken the pin out of the nozzle assembly. Where it was in the, "rescue" position. And now we're going to advance the nozzle, into the "fire" position. The pin as you see, plays an integral role in this. On the top of the pin is a plunger: it's a spring-loaded plunger. On the bottom, you see two spring-loaded, protrusions out. As you push the plunger, the protrusions go in, and it allows you to drop the pin into place. The spring loaded protrusions pop out, and it prevents the pin from juggling loose out of the assembly and keeping it safely all in one place. This pin was taken out of the assembly here. In a minute we're gonna move the nosel assembly up to here where the pin is then gonna be dropped down through the nosel will be advanced up to the fly section and we're gonna be ready to start water. [MUSIC] [MUSIC] [MUSIC] As you can see, we've retracted the ladder back and we're now ready to proceed. We're going to take the pin from the rescue position and now put the pin into the fire position. And now get ready to start water. [SOUND]. We have demonstrated now the importance of the pin in this assembly. Understand that members have died by not having the pin in properly and the nozzle assembly has actually rocketed off the truck. In many other cases. In our next segment, please stay tuned next month as we're going to talk about water hammer as it relates to supplying water to this particular appliance in this piece. Thank you for watching Fire Engineering Training Minutes. I'm Mike Wolber and we'll see you next time.
