Trunk Tunneling

Dave Dalrymple and his crew demonstrate how to extricate patients by proceeding through the trunk and into the front of the vehicle. Sponsored by Holmatro.



[BLANK_AUDIO] [MUSIC] [MUSIC] Hello, rescuers. Welcome to Fire Engineering Training Minutes. I'm Dave Dalrymple. In this segment, we're going to talk about trunk tunneling. Now, the first thing that comes to mind when you hear trunk tunneling for vehicle extrication, is the vehicle's. Under road a larger vehicle, say a box trunk or a tractor trailer. But also take in to considerations too today, what happens if your tools can't cut or sever the roof post and you have no access to the sides of the vehicle or the sides are so damaged you can't get the sides open either. Think about the kind of construction and materials that go into vehicles today. So one of the things that, even though it might sound far-fetched, it's becoming more and more reality is. Maybe we need to displace the back of the vehicle in some way, shape, or form. And one of the ways to do that is to tunnel through the trunk to get to our occupants in the front. Now, in order to do this we have to go, we have to force the trunk. When the trunk lifts up, we either cut it or displace it in some way. We cut the package deck. Get rid of that. We get rid of the seatback after that. And then the seat bottom will follow that, will follow that. Get that out of the way, and then we'll be to the front seats to where our patients are to get them out. So now let's watch this evolution as we walk through it and the crew walks through and shows you how to do it step by step. Rescuers, the crew is gonna come in and start our trunk tunneling evolution. First they're gonna make. A purchase point and then they're gonna force the trunk. Now, once the trunk is opened, they're gonna come in, they're gonna inspect to see if there's any type of debris, any type of materials or anything like that that needs to be moved out. Prior to starting the trunk tunneling evolution. Then they'll actually cut the trunk off the vehicle. [MUSIC] [SOUND]. [MUSIC] Okay, rescuers, now that we've taken the trunk away from the vehicle, the next part of the vehicle we need to do in our truck tunneling evolution is we need to remove the package deck. The crew is gonna make a relief cut on each side of the package deck with a hydraulic tool, and then they're gonna finish the cuts forward with a reciprocating saw, and then across. The entire deck to get it out of the vehicle. [SOUND] [MUSIC] [MUSIC] [SOUND] [NOISE] [SOUND]. [MUSIC] [SOUND] [SOUND] We're seeing the packet shelf being removed. The crew here cut through the torsion bar that hinges the trunk up and down. One of the other options you can do with that torsion bar. Is either pop it, or push it out of the way with either a halligan, a fubar tool, or a small combi tool to get in there, just push it out of the way, and it'll pop out and release. Okay, rescuers, now that we've removed the package shelf, the Cur is gonna come in and inspect the rear seat back. The rear seat back is usually held at the bottom by either a bolt, a bracket, or a tab of metal. Something fairly simple. The crew is gonna do two different evolutions here to show you two different options. On the driver's side, we're gonna take a combination tool, and actually spread the seat back off of the tab. [MUSIC] [SOUND]. [MUSIC] Now rescuers on the passengers' side, we're going to take the power hydraulic cutter and we're going to actually cut through the tab. Again, this two different options to show that we can use a variety of different tools for this instance. This. [SOUND] Now that the crew has finished removing those tabs. The seat back, can be removed from the vehicle. We have the option of either leaving the seat bottom in place, for the rear seat. Or, taking it out, to give us some extra room. Okay rescuist's, wrap up this evolution, we're gonna disentangle the patient at this point. The crews gonna come in, they're gonna fold the driver seat down. To extricate the patient. And then they're gonna insert a long spine board. Now as you can see, once the board goes in even with the roof on the vehicle there's a tremendous amount of space. You'll have very little difficulty removing the patient from the vehicle. Now, again, remember, trunk towing can be used for vehicle. For an under ride override situation, but also, say we're in the situation where the vehicle has roof posts where you can't sever it with your tools, you can stretch the roof out and do a trunk tunneling to make space to move your patients just as well. Now, we watched how we did the trunk tunneling maneuver, step by step. Couple things to remember as we do this though. Always, with any kind of tool of evolution. Need to put a hard barrier between your patient, and interior rescuer. Some sort of hard protection. We also wanna cover up sharp edges as we work. Because we don't wanna be injured, nor do we wanna injure the patient as they're coming out, being disentangled. But one of the things to remember with trunk tunneling as well, Hybrids and alternative fuel vehicles, we have to always be careful of what's in the trunk of these vehicles. Specifically, the Honda Civic Hybrid, the Honda Accord Hybrid, and the new Ford Fusion Hybrid and Mercury Milan Hybrid. Those vehicles, the high voltage battery actually lives in this rear seatback itself. So, we don't want to tunnel through that trunk area. That would be bad to cut through the high voltage battery. I'd like to thank Hobracho. I'd like to thank you for watching training minutes. My name is Dave Dalrymple. Be safe out there.
