-- -- -- -- -- -- -- -- -- -- Today's evolution. We're gonna talk about proper cutting techniques -- -- power hydraulic cutters. Now most of your thinking. Dave I know how how -- -- guard -- works you know he goes up and cut things. What's the big deal for most of us when we learn how to cut. Things with a power hydraulic cutter -- was mostly sheet metal and it was a long time ago because up until fairly recently. Our cutters could not cut hard materials. Even -- -- lapses. So let's watch as a crew takes a student through how to cut parts of the vehicle we're. -- power hydraulic -- Prepare students gonna go up. And start his first cut -- and a new car technology Michael blade cutter. However. As you noticed. On the wrong side of the tool you never want to be between the -- pool and the vehicle. -- one of the things that you'll notice with. These. New -- technology like blades. Because of the shape -- the blade and and crimes. The pool will -- and torque on small. Items or sheet metal. One of the things to try and correct it is -- stop. Reposition the tool. Maybe flip it over to get a different angle. To make -- cut. Especially at the -- starts to going there actually do not want to go and remember. You want to let the -- do the work. You control the tool. You'll not be able to. Forced a tool to go one direction or the other. One of the things as you make your cut. Let the -- work all the way. That means even if you think the -- has stopped. Let the -- continue to run for a short period of time to make sure that cut is complete. And straight through. Whether -- sheet metal or hard and materials. Such is -- hard and reinforcement. Or changes or lapses. Now in this particular instance the students kind of -- a crash theme of the door. -- the -- -- should be approached at a ninety degree angle. Basically at a right angle to what's being cut. And since it has canceled its. It's going to react. Violently. When it's being seven. Now here in the student is going to make it caught on the B post. One of the first things he should check it where's the adjustable seatbelt bracket. Do. The choice of where cool let me cutting with the -- -- -- Want things to remember economy tool will not make a complete straight -- And also. As it squeezes. It will push away from where it's being. Remember your selection of Carter. But what's being caught it always -- match. Need to think a little bit about. Where -- your cutting what you're currently it. If we only have one -- that you have to do the best you can. Put a copy tool type of cut hear him -- being -- Is very difficult to try and cut want the size of it and the shape it. Because it's actually gonna -- it should be -- away. But the other point was that choice though. Location. Because he's trying to cut through me -- adjustable seatbelt bracket. Now again because we're cutting you'll pardon material. We need to let the Carter work -- all the way through this cycle that we need to keep the troll handle hell. It's always sure that that school is completely stop. The other part of this -- is. Many times because of the size of the cut and the size of -- -- You're gonna need to approach. The -- post cut. From different angles and different direction. Now what we're gonna show you is we're gonna show you -- three different. Types of cutters we used in this scenario today. The first -- as a comical which is basically a straight -- -- The second -- Is a new car technology type of -- New -- technology blades. And our last putter. There's going to be a nine inch. You L Connor or and here we have type of O'Connor. Now as you can see from each cutter each -- has dynamics. Individual to its own due to -- -- shape and size of the blade. Involved. -- giving them advantages and disadvantages for each type of cut. Depending on the situation. Okay when we're fighting hard and things such as crash means. Reinforcement. Latches and hinges. A new vehicle. Type of blade is is optimal. For you. So here. We're gonna cut McCain. And we're gonna cut the latch closed door. -- you can see the -- -- of this vehicle was peeled off. Because we try to do -- blue door pop. That failed. Using a -- The tactic of way to go today. It's been exposed -- -- their laps. Rather and then cut them. Such as we're doing now. -- -- -- Much safer. For the tool operator the patient. And it's easier on the pool itself. Most of these cuts you've seen us do today. Are surrounding cut. Where the actual -- has surrounded the object that's been. When we're cutting him is -- laughter we want to make sure artful ways to go completely around them. We don't want to hit the -- The tops and -- -- -- -- -- -- That won't ship load the -- And more than likely break that school. The other type of cut. Is -- penetrating cut. For example like we tried to perform live. -- -- -- -- -- -- -- -- Again one other thing -- listened for. As we make our cut. Listen for the power unit many primes are powered units have a second stage. You might think that -- was stopped working. But actually moved into the second stage to increase our. And again. We're gonna cut the wires between the vehicle in the and the door. It is the fact that power hydraulic cutters can make static electricity. We wanted to try and eliminate that by using -- Okay rescuers. -- just watched our instructors show -- student. How to -- various components of the vehicle. With a variety of different power hydraulic cutters. But if we cut -- -- material. Would cut sheet metal which -- why component we cut our -- Who -- it showed you how to use. It's protection corporate protection we showed you how to use proper patient protection that's gonna protect the EMS provider and the -- I'd like thank you for watching training and I'd like to think we'll watch -- -- sponsoring -- and training them. Be -- out there.
