[MUSIC] Welcome to Fire Engineering's Training Minutes, my name is Dave Dalrymple. Today we're going to talk about alternative tool evolutions. Well, when you think about alternative tool evolutions, what comes to mind? Think about the way vehicles are made today, what they're made of and some of the components that comprise part of the vehicle. Some of our two evolutions we're used to in the past are gonna be more and more and more difficult to do as time grows long. So two of the evolutions we wanna show you today all are turnative methodology to some of the evolutions we do every day. One of them has actually been around for quite awhile. That's a roof trench. The other evolution we're going to show you is a roof tent evolution. Now if you watch, our rescue crew is going to go through this step by step for each one of these. [MUSIC] Okay, our rescue crew is going to come in they're going to do a roof tent evolution first. Now one of the things we wanna try and do first, before we start lifting the roof, we wanna put some sort of cribbing underneath on the package deck to help spread the load across the package deck. Now they put the sp, spreader in place next into the window opening [MUSIC] And as the tool spreads and opens it up, it lifts the roof, thus widening the rear window area. [MUSIC] Okay, rescuers, one of the things we can do to improve upon our roof tent evolution, we can make two relief cuts inboard of the last roof post on the rear window, and open the roof even farther, like a can opener. We're gonna leave our spreader in place, putting it under, keeping the roof under tension as we make our cuts. Now one of the things to remember, we've already pulled the trim on the inside of the post so we know there are no hazards. [MUSIC] [MUSIC] [SOUND] Now, once the relief cut is done, we're gonna lift the roof again. Now you can see we've gained actually even more space with our roof tent evolution this time. [MUSIC] Kay rescuers, now we're gonna do a roof trench evolution. That's gonna be basically a cut in board of the roof edge on each side, with the saws all, a hydraulic tool, and air chisel. One of the things with this tool evolution, the tool operator is gonna run the tool and you're gonna have at least one or more rescuer to watch and guide the tool operator as the tool passes down the loop side. [SOUND] [NOISE] [SOUND]. [SOUND] [SOUND] [SOUND] 'Kay, good tip, once we've made a cut down the one side of the vehicle, would be to swap the blade on the sawzall. Now we wanna also make sure we wanna unplug whatever power source it runs by, whether it's a battery 110 or here in this example, a robo pack. Unplug it before you change the blade. Then plug it back in. One of the things to be aware of too if the roof has a sol-, has a sunroof. Of some type it's gonna have extra weight to it. Make sure you have enough rescuers on hand to manage the roof. Rescuers a tip to hold the roof up on the other side because it's a very sharp edge. Each of the rescuers on the driver's side have put a pry bar in place so they don't pinch their fingers or cut their hand as it's being cut to hold the roof up. [SOUND] [SOUND] [SOUND] [SOUND] [NOISE] [MUSIC] Now that the roof is removed, we're going to make sure we cover up all the sharp edges. [MUSIC] Okay we just watched our crew go through alternative too evolutions a roof trench and a roof tenting operation. The ideas behind these again is to get around some of the issues with vehicle construction and technology. Remember though, with every, any type of tool evolution you do, we still need to put a hard protection barrier between our patient and our interior rescuer. You wanna make sure that the trim is pulled any time you're working around the roof environment to make sure we don't run into any side curtain airbags. And to be sure to cover up sharp edges as we go. Now I'd like to think our sponsor [UNKNOWN] I'd like to thank you for watching training minutes today, and be safe out there.
