Steve White demonstrates basic extrication techniques for cabs of large-sized trucks like big rigs.
[SOUND]. Welcome to Fire Engineering's Training Minutes. I'm Steve White, Battalion Chief, Fishers Fire Department. In this segment were gonna discuss basic extrication to the cab of the truck. Again, building on our principles that you can't take a small vehicle approach. To a big truck rescue. A simple task is moving the door can be very challenging. When we look at certain items such as the mirror, the breather, the grab handle, and the stack. Even looking the door on size up with the latches, we cannot be sucked into thinking that that's where the neater is. On this evolution we're gonna attack the door from the nater side. I open the door, you can see that the nater actually latches at the center of the door frame. So that's where our tool work needs to begin while we're doing this tactic. As in every other extrication evolution the vehicle is stabilized through four points of contact. We have box cribbing. On four points at the front and the back. We're gonna start with gaining access through glass removal. Remember, when we have a victim, it's important to make sure that they're covered with a rescue blanket. Typically our side glass is tempered and can be removed with a standard center punch. When we remove the windshield, it is also a standard laminate. Two piece laminate usually is kept in place by a two-part gasket which we'll remove to get the windshield out. There are several different ways that we can remove the laminated glass through the gasket. One is pulling the center bead. [SOUND] >> They're making that gasket loose. Ultimately the goal was that we were trying to take it out without having to use a glass tool, which reduces the amount of small pieces of particle and glass that are associated with using a glass tool. [SOUND] >> As you can see from working outside the cab. Having the victim covered, removing of the windshield is relatively simple. [NOISE] >> Over here. [NOISE] >> In this step, working as a team, we're going to remove the [NOISE]. >> [NOISE]. >> [SOUND] Here something important to remember: we must steady the object before we cut it. >> [SOUND] Dropping the object down control, and then carrying it away, is a good safe approach. [BLANK_AUDIO] [NOISE]. >> [NOISE]. >> (Sound of drilling) [BLANK_AUDIO] [NOISE] It's always important to remember that we should never place ourselves between the tool and the vehicle. [NOISE] >> Now we have all the obstacles removed from our means of attacking the door at the nater word pin. One thing I wanna point out in the na, evolution was that we used a combination of tools. Power hydraulics. [UNKNOWN] and chisels, which can all be used on these various components. The next step is to attack the nadir in the door and get it removed. One thing that we wanna point out, as you can see, the use of the ladder is pretty critical for rescuer safety. As an alternative, you could bring in a flat bed wrecker which provides a, a base of stability for the rescuers when operating their tools. Otherwise, we'll be working above our waist which is where our common point is for attacking cars. But now, we're going to be a bit higher. We can also do that with an in-frame ladder. But by using a flat bed wrecker, we've provided a suitable base for our personnel, our equipment, and even to the final step, when you remove the victim, because just imagine trying to get a victim out of that seat with a great deal of height to overcome. The flat bed wrecker when special called for. Can address a lot of these challenges for rescuers in big truck extrication. To gain access to the, in there, we're gonna try to gain a purchase point so we can fit the tips of the spreader between the door and the B post [SOUND] Gaining access to the layer can be very challenging. So, starting at the top of the door frame and tunneling your way down is usually your best approach. [SOUND] >> Once the nader is exposed, we can either continue attempting to spread, or we can gain enough room to get the cutters in to cut the door from the nader. [NOISE] Now come down. [NOISE] There you go. [NOISE]. [SOUND] [INAUDIBLE] [SOUND] [SOUND]. [SOUND] Now that the evolution is done, you can see how we were able to remove the door. Attacking from the [UNKNOWN] pin really is very challenging. A good alternative option would be to go from the hinge side. So, rescue, being the science of alternatives, you've got to be able to take from this evolution, what the actual impact or the accident will give you. The use of a flatbed wrecker, again, proved its worth in providing a safe base for rescuers to keep their tools at their waists, not bring it above their waist. Having a good platform for balance and control. And had we had a victim, to be able to package and remove onto the platform, to the edge, to a waiting personnel. To take, to transport to the hospital. That concludes this segment for training minutes. We'd like to thank [UNKNOWN] for sponsoring the segment. [BLANK_AUDIO]
