Okay once we've. Finished or stabilization we're gonna go move on to glass management and our member. We have three different types of windows that we can run -- out in the street. Laminated glass mostly from underway and we see -- all the -- -- windshield but remember. Laminated glass which is. Two layers of glass with a layer of plastic sandwich in the -- Besides the windshield he also sometimes confided -- side and rear windows on vehicles today. This type of glass we need to cut out to remove it from the vehicle. A -- second type of the last. -- safety glass. -- safety blast remember when it breaks -- and a small grains or pieces unlike laminated glass where it's a sandwich of glass and plastic together. -- to break out. This time -- gonna -- it impact device some sort of senator punch glass hammer. Or such like that does that impact us large amount of force into a small area on the window itself. Gonna break it's gonna -- for the groundbreaking. Right our third title glazing is going to be -- Carmen or Alexa and material now whereas that's not. -- that widely available yet we see in a mass transit vehicles buses trains planes and such like that. But in passenger vehicles it's fairly new. -- good example Seattle street -- the Ford Escape hybrid. Where it has the driver's side. Last window. Is also Lex and his as the -- air intake for the positive pressure system for the high voltage battery. That's -- window that's not gonna be broken by either our conventional tools either for laminated windows. Or tempered glass windows that type of materials and gonna need to be caught out with such as a reciprocating saw because it's glued in place. It wanna be instrument -- what we -- -- management. Our PP -- whereas were wearing our normal type of year. Helmet gloves. Here -- we will also need our protection we also need respiratory protection our port -- walking. Breathing apparatus. But when we cut -- windows were produced glass dust. Now we need to make sure that we protect their -- with such as it in 95 -- -- some simple type of dust mask that's gonna prevent that dust from entering our -- -- We want to make sure that that -- -- up when we're doing our glass management protect. -- to start our windshield removal because it's laminated glass. To cut it out we're gonna start with an access hall somewhere in the middle of the vehicle that we're gonna cut out around -- -- -- to remove the -- Now whether it's with a glass all our recent soft -- basically for work the same way you get rid of them for a flinch. All the way around same thing if the rear window is laminated as well. It. Yeah. Okay for glass management. We just cut out the laminated windshield in the front. In doing that we use a glass soft now glass soft it's a good tool for that but also remember if you upside. Windows that are laminated. Gonna need -- cut that out as well. -- tempered glass we've got a combination of tools to show you today. A glass hammer which we've all seen in -- and trade publications or wherever. Where it's basically impact device you're gonna swing it into the corner of the windows and pack a lot of force in that area to break it -- it. Ross and I have -- bring senator punch. Which is basically -- -- that's gonna put against the window -- back apart and let it slide back together which is gonna impact the same kind of tremendous amount forced into a small corner recognized. If. It. And also a spring loaded center punches well that will do the same thing. Breaking glass. Okay when we go up to remove our side windows or any glass in that matter -- you wanna do you wanna make sure that you announce it. So not only the rest of the crew on the outside can hear it. But also the EMS provider inside take care the patient. So -- go up to break glass we're gonna announce it breaking glass. Say it loud enough so everybody in the area can -- we know what works being done. Breaking. Think lasted broken -- it drops out victory in the window out with a cool not your hands clasped. Just stick its lumps themselves. Just show you some different techniques different -- -- absolutely right now have a lot.
